New scientific discoveries are moving society toward the era of “personalized solar energy,” in which the focus of electricity production shifts from huge central generating stations to individuals in their own homes and communities.


That’s the topic of a report by an international expert on solar energy scheduled for the November 2 issue of ACS’ Inorganic Chemistry, a bi-weekly journal. It describes a long-awaited, inexpensive method for solar energy storage that could help power homes and plug-in cars in the future while helping keep the environment clean.

Daniel Nocera explains that the global energy need will double by mid-century and triple by 2100 due to rising standards of living world population growth. Personalized solar energy — the capture and storage of solar energy at the individual or home level — could meet that demand in a sustainable way, especially in poorer areas of the world.

The report describes development of a practical, inexpensive storage system for achieving personalized solar energy. At its heart is an innovative catalyst that splits water molecules into oxygen and hydrogen that become fuel for producing electricity in a fuel cell. The new oxygen-evolving catalyst works like photosynthesis, the method plants use to make energy, producing clean energy from sunlight and water.

“Because energy use scales with wealth, point-of-use solar energy will put individuals, in the smallest village in the nonlegacy world and in the largest city of the legacy world, on a more level playing field,” the report states.

Professor Guillermo Bazan and a team of postgraduate researchers at UC Santa Barbara’s Center for Polymers and Organic Solids (CPOS)  have announced a major advance in the synthesis of organic polymers for plastic solar cells.

Bazan’s team reduced reaction time by 99%, from 48 hours to 30 minutes, and increased average molecular weight of the polymers by a factor of more than 3.

The reduced reaction time effectively cuts production time for the organic polymers by nearly 50%, since reaction time and purification time are approximately equal in the production process, in both laboratory and commercial environments.

The higher molecular weight of the polymers, reflecting the creation of longer chains of the polymers, has a major benefit in increasing current density in plastic solar cells by as much as a factor of more than four. Over polymer batches with varying average molecular weights, produced using varying combinations of the elements of the new methodology, the increase in current density was found to be approximately proportional to the increase in average molecular weight.

The methodology, detailed in a recent Nature Chemistry paper, “will greatly accelerate research in this area,” stated Bazan, “by making possible the rapid production of different batches of polymers for evaluation.” He further noted, “We plan to take advantage of this approach both to generate new materials that will increase solar cell efficiencies and operational lifetimes, and to reevaluate previously-considered polymer structures that should exhibit much higher performance than they showed initially.”

To make these gains, the team:

Mike McGehee, Director of Stanford’s Center for Advanced Molecular Photovoltaics, hailed Bazan’s work, commenting, “Many synthetic chemists around the world are making copolymers with alternating donor and acceptors to attain low bandgaps. Most of them are having trouble attaining adequate molecular weight, so this new synthetic method that creates longer polymer chains is a real breakthrough. The reduction in synthesis time should also make it easier to optimize the chemical structure as the research moves forward and will ultimately reduce the manufacturing cost.”

Bazan is a Professor of Chemistry and of Materials at UC Santa Barbara, and is co-director of CPOS and a faculty member at the NSF-funded Materials Research Laboratory.

The ocean is a potentially vast source of electric power, yet as engineers test new technologies for capturing it, the devices are plagued by battering storms, limited efficiency, and the need to be tethered to the seafloor.

Shown is the view from the far downstream end into the test section of the U.S. Air Force Academy water tunnel. Three blades of the cycloidal turbine are visible at the far end. Engineer Stefan Siegel and his colleagues test the turbine using the tunnel, with both steady and oscillating flow conditions simulating a shallow-water wave-flow field.

Now, a team of aerospace engineers is applying the principles that keep airplanes aloft to create a new wave-energy system that is durable, extremely efficient, and can be placed anywhere in the ocean, regardless of depth.

While still in early design stages, computer and scale-model tests of the system suggest higher efficiencies than wind turbines. The system is designed to effectively cancel incoming waves, capturing their energy while flattening them out, providing an added application as a storm-wave breaker.

The researchers, from the U.S. Air Force Academy, will present their design at the 62nd annual meeting of the American Physical Society’s Division of Fluid Dynamics on Nov. 24, 2009, in Minneapolis, Minn.

“Our group was working on very basic research on feedback flow control for years,” says lead researcher Stefan Siegel, referring to efforts to use sensors and adjustable parts to control how fluids flow around airfoils like wings. “For an airplane, when you control that flow, you better control flight–for example, enabling you to land a plane on a shorter runway.”

A colleague had read an article on wave energy in a magazine and mentioned it to Siegel and the other team members, and they realized they could operate a wave energy device using the same feedback control concepts they had been developing.

Supported by a grant from the National Science Foundation, the researchers developed a system that uses lift instead of drag to cause the propeller blades to move.

“Every airplane flies with lift, not with drag,” says Siegel. “Compare an old style windmill with a modern one. The new style uses lift and is what made wind energy viable–and it doesn’t get shredded in a storm like an old windmill. Fluid dynamics fixed the issue for windmills, and can do the same for wave energy.”

Windmills have active controls that turn the blades to compensate for storm winds, eliminating lift when it is a risk, and preventing damage.

The Air Force Academy researchers used the same approach with a hydrofoil (equivalent to an airfoil, but for water) and built it into a cycloidal propeller, a design that emerged in the 1930s and currently propels tugboats, ferries and other highly maneuverable ships.

The researchers changed the propeller orientation from horizontal to vertical, allowing direct interaction with the cyclic, up and down motion of wave energy. The researchers also developed individual control systems for each propeller blade, allowing sophisticated manipulations that maximize (or minimize, in the case of storms) interaction with wave energy.

Ultimately, the goal is to keep the flow direction and blade direction constant, cancelling the incoming wave and using standard gear-driven or direct-drive generators to convert the wave energy into electric energy. A propeller that is exactly out of phase with a wave will cancel that wave and maximize energy output.

The cancellation will also allow the float-mounted devices to function without the need of mooring, important for deep-sea locations that hold tremendous wave energy potential and are currently out of reach for many existing wave energy designs.

While the final device may be as large as 40 meters across, laboratory models are currently less than a meter in diameter. A larger version of the system will be tested next year at NSF’s Network for Earthquake Engineering Simulation (NEES) tsunami wave basin at Oregon State University, an important experiment for proving the efficacy of the design.

The conference takes place from Nov. 22-24, 2009, at the Minneapolis Convention Center. The conference is the year’s largest devoted to fluid dynamics, bringing together researchers from across the world and across a wide range of disciplines.

Idaho National Laboratory (INL) scientists have set a new world record with next-generation particle fuel for use in high temperature gas reactors (HTGRs).

The Advanced Gas Reactor (AGR) Fuel Program, initiated by the Department of Energy in 2002, used INL’s unique Advanced Test Reactor (ATR) in a nearly three-year experiment to subject more than 300,000 nuclear fuel particles to an intense neutron field and temperatures around 1,250 degrees Celsius.

INL researchers say the fuel experiment set the record for particle fuel by consuming approximately 19 percent of its low-enriched uranium — more than double the previous record set by similar experiments run by German scientists in the 1980s and more than three times that achieved by current light water reactor (LWR) fuel. Additionally, none of the fuel particles experienced failure since entering the extreme neutron irradiation test environment of the ATR in December 2006.

“This level of performance is a major accomplishment,” said Dr. David Petti, Director of the Very High Temperature Reactor Technology Development Office at the U.S. Department of Energy’s INL. The purpose of the fuel program is to develop this particle fuel, produce experimental data that demonstrates to the Nuclear Regulatory Commission that the fuel is robust and safe, and re-establish a U.S. fuel manufacturing capability for high temperature gas reactors. INL has been working with Babcock and Wilcox Inc., General Atomics and Oak Ridge National Laboratory (ORNL) to establish standards and procedures for the manufacture of commercial-scale HTGR fuel. The overarching goal of the AGR Fuel Program is to qualify coated nuclear fuel particles for use in HTGRs such as the Next Generation Nuclear Plant (NGNP). Developing particle fuel capable of achieving very high burnup levels will also reduce the amount of used fuel that is generated by HTGRs.

“An important part of our mission is the development and exploration of advanced nuclear science and technology,” said Dr. Warren F. “Pete” Miller, assistant secretary for Nuclear Energy. “This achievement is an important step as we work to enable the next generation of reactors, decrease fossil fuel use in industrial applications, make fuel cycles more sustainable, and reduce proliferation risks.”

“AGR-1″ is the first of eight similar experiments which aim to confirm designs and fabrication processes and performance characteristics for such fuel. Future AGR fuel tests will include particle fuel produced on a prototypic industrial scale to further prove the irradiation performance of the NGNP-specific fuel design. The 18-foot-long AGR-1 experiment was inserted in INL’s ATR core and allowed for each of six capsules containing the particle fuel specimens to be monitored and controlled separately. Inside the ATR core, the fuel specimens were subjected to neutron irradiation many times higher than what they would experience inside an HTGR or a current light water reactor, allowing INL researchers to gain irradiation performance data for nuclear fuel and materials in a shorter time. The team is monitoring the AGR fuel for a number of factors including “burn-up,” which is a measurement of the percent of uranium fuel that has undergone fission reactions.

Although the experiment has now left the ATR, researchers still have more work to do before the AGR-1 test campaign will be finished. Post irradiation examination (PIE) will begin at INL and ORNL facilities and allow scientists to examine the fuel up close so that the fuel and its layers of coatings can be evaluated for degradation patterns and other characteristics. In addition, controlled higher temperature testing in furnaces is planned to determine the safety performance of the fuel under postulated accident conditions. These activities will last another two years.

The Next Generation Nuclear Plant Program aims to use a high temperature gas reactor to produce high temperature process heat and hydrogen used by many industrial facilities in daily operations and to support the broader goal of developing the next generation of nuclear power systems that provide abundant carbon-free electricity on a 24/7 basis. Excellent fuel irradiation performance must be demonstrated before high temperature gas reactors can be licensed and co-located with these complementary industrial facilities. Reaching this world record peak burn-up of 19 percent without any particle failure demonstrates the robustness of this particle fuel design.

The purpose of the fuel program is to develop this particle fuel, produce experimental data that demonstrates to the Nuclear Regulatory Commission that the fuel is robust and safe, and re-establish a U.S. fuel manufacturing capability for high temperature gas reactors. INL has been working with Babcock and Wilcox Inc., General Atomics and Oak Ridge National Laboratory (ORNL) to establish standards and procedures for the manufacture of commercial-scale HTGR fuel. The overarching goal of the AGR Fuel Program is to qualify coated nuclear fuel particles for use in HTGRs such as the Next Generation Nuclear Plant (NGNP). Developing particle fuel capable of achieving very high burnup levels will also reduce the amount of used fuel that is generated by HTGRs.

“An important part of our mission is the development and exploration of advanced nuclear science and technology,” said Dr. Warren F. “Pete” Miller, assistant secretary for Nuclear Energy. “This achievement is an important step as we work to enable the next generation of reactors, decrease fossil fuel use in industrial applications, make fuel cycles more sustainable, and reduce proliferation risks.”

“AGR-1″ is the first of eight similar experiments which aim to confirm designs and fabrication processes and performance characteristics for such fuel. Future AGR fuel tests will include particle fuel produced on a prototypic industrial scale to further prove the irradiation performance of the NGNP-specific fuel design. The 18-foot-long AGR-1 experiment was inserted in INL’s ATR core and allowed for each of six capsules containing the particle fuel specimens to be monitored and controlled separately. Inside the ATR core, the fuel specimens were subjected to neutron irradiation many times higher than what they would experience inside an HTGR or a current light water reactor, allowing INL researchers to gain irradiation performance data for nuclear fuel and materials in a shorter time. The team is monitoring the AGR fuel for a number of factors including “burn-up,” which is a measurement of the percent of uranium fuel that has undergone fission reactions.

Although the experiment has now left the ATR, researchers still have more work to do before the AGR-1 test campaign will be finished. Post irradiation examination (PIE) will begin at INL and ORNL facilities and allow scientists to examine the fuel up close so that the fuel and its layers of coatings can be evaluated for degradation patterns and other characteristics. In addition, controlled higher temperature testing in furnaces is planned to determine the safety performance of the fuel under postulated accident conditions. These activities will last another two years.

The Next Generation Nuclear Plant Program aims to use a high temperature gas reactor to produce high temperature process heat and hydrogen used by many industrial facilities in daily operations and to support the broader goal of developing the next generation of nuclear power systems that provide abundant carbon-free electricity on a 24/7 basis. Excellent fuel irradiation performance must be demonstrated before high temperature gas reactors can be licensed and co-located with these complementary industrial facilities. Reaching this world record peak burn-up of 19 percent without any particle failure demonstrates the robustness of this particle fuel design.

As part of developing new energy resources that don’t emit carbon dioxide, the DOE is funding 9 trials that use supercritical CO2 to extract more geothermal energy.


The idea started in 2000 at Los Alamos National Laboratory; when physicist Donald Brown thought of pumping geothermal fluid using supercritical CO2 – a pressurized form that is part gas, part liquid; instead of water.  Theoretically this should flow more freely through rock than water, because it is less viscous than water.

Then, six years later; in modeling the technology Lawrence Berkeley hydro-geologist Karsten Pruess projected that not only should it perform as expected but that it would also yield a 50% hotter geothermal resource.

Now the DOE is funding this promising research with $16 million in nine trials to see if this will work in the real world.

The funding is to be shared by nine carbon dioxide-related projects led by Lawrence Berkeley National Laboratory and other national labs and universities, and the Californian combinatorial chemistry firm Symyx Technologies that screens about a million potential materials a year using advanced computer modeling.

Brown’s idea was that the density difference between the supercritical CO2 pumped down and the hotter gas coming up would make the gas cycle better by a siphoning action, so the pumping process would use less energy.

Symyx project leader and materials scientist Miroslav Petro wants to make sure that supercritical carbon dioxide plays nicely with rock and minerals. It could form a super-dissolving “acidic soda water” that dissolves minerals from rocks.

Sequestering the carbon would be the big bonus. It could be a large amount: 70 years worth of CO2 emissions from a 500 megawatt coal power plant.

Dell has been a trend-setter when it comes to the incorporation of greener technologies to reduce their corporate carbon footprint and they’re doing it again! Although this time they are following the lead of Google, by installing solar trees in the parking lot of their head office in Round Rock, Texas.


The solar trees were created by Envision Solar, which was also responsible for Google’s installation, and will accomplish more than one goal for the company – providing a green solar option that will provide some level of power to the headquarters site, and create charging stations for employees in the staff parking lot. Although Envision Solar engineered the project, the solar panels themselves are byproducts of BP Solar and the charging points themselves, which will provide plug-in energy for those driving hybrid and electric vehicles to work at Dell, come from Coulomb Technologies.

The solar trees will provide 130,000 KW per year to the facility, and also offer shade and charging points to staff in the parking lots; the only downside of this installation is that the trees are only accessible for shade and charging for a small percentage of Dell employees who drive to work since they cover a mere 56 spots and have 2 Clean Charge stations for plug-in power in the Round Rock lot.

Carbon is usually typecast as a villain in terms of the environment but researchers at the University of Warwick have devised a novel way to miniaturise a technology that will make carbon a key material in some extremely green heating products for our homes and in air conditioning equipment for our cars.

Most domestic heating and automotive air conditioning requires a lot of energy. Domestic space heating and hot water account for 25% of energy consumption in the UK. Across the EU, vehicle air conditioning uses about 5% of the vehicle fuel consumed annually, and within the UK it is responsible for over 2 million tonnes of CO2 emissions.

To combat global warming, new technologies to reduce these emissions are vital. Researchers at the University of Warwick have been working on practical solutions for many years and are now developing new energy saving technologies.

In houses, the best condensing boilers are about 90% efficient. There are electric heat pumps on the market that use electricity to extract heat from the outside air or the ground to heat homes more efficiently, but the electricity used still incurs large CO2 emissions at the power station. Researchers have long been aware of a much more energy efficient way to drive heat pumps (or air conditioners) using adsorption technology. This uses heat from a gas flame or engine waste heat to power a closed system containing only active carbon and refrigerant. When the carbon is at room temperature it adsorbs the refrigerant and when heated the refrigerant is driven out. A process which alternately heats and cools the carbon can be used to extract heat from the outside air and put it into radiators or hot water tanks. In the case of air conditioning it extracts the heat from the inside of the car. The major snag has been that adsorption technology to date would need to be roughly 300 litres in volume for a car air conditioner and larger for a heat pump to heat your house. Clearly that is not going to fit into a car and the volume of unit required for domestic heating probably couldn’t fit under your stairs at home either…

However University of Warwick researchers have made a breakthrough in adsorption systems design that dramatically shrinks these devices making them small and light enough for use in both domestic heating and automotive air conditioning. They have devised and filed a patent on a clever new arrangement that distributes thin (typically 0.7mm thick) sheets of metal throughout the active carbon in the heat exchanger. Each of these sheets contains more than a hundred tiny water channels (typically 0.3mm in diameter) designed to make the heat transfer much more efficient. This has enabled the Warwick team to create adsorption based equipment that is up to 20 times smaller than was previously possible.

The researchers expect that their new adsorption technology can create domestic heat pumps that will produce a 30% or more reduction in domestic fuel bills (and CO2 emissions) compared to even the best condensing boiler. In car air conditioning systems their new system can exploit waste heat from the engine, converting it into useful cooling. Because no (or very little) mechanical power is then taken from the engine it will reduce both fuel consumption and CO2 emissions by nearly 5%. The research team also anticipate that in new vehicle models the system can be integrated with little or no extra cost.

The University of Warwick engineers have had significant interest in the new technology from a range of companies, and they have already entered a technical partnership with a major global vehicle manufacturer to develop and demonstrate the technology. There has also been considerable interest from the domestic heating and hot water market

This significant commercial interest has led to a new spin-out company, Sorption Energy Ltd, being set up by Warwick Ventures, the university’s technology transfer office, and H2O Venture Partners. Initially the company will use the new patent pending technology to focus on two high value markets: greener heating and hot water systems for houses and air conditioning for cars.

Lead researcher on the new technology, University of Warwick’s Professor Bob Critoph said:

“My team has been working on these developments for several years, supported by grants from EPSRC and the EU totalling over £2.5million. The technology is now ready for commercialisation and we are very excited by the opportunities which are developing. It is particularly pleasing that the technology will significantly help reduce CO2 emissions.”

Dr David Auty, Chief Executive of Sorption Energy said: “This is exciting stuff. The technology has been proven in the University’s laboratories at the sizes needed for vehicles and domestic systems, and there are several other large markets. The ability to provide products which make significant reductions in both energy consumption and CO2 emissions at a similar price to existing products will make Sorption Energy very attractive to customers, and is very satisfying for the team.”

“The UK is the global market leader in gas boilers. There are 21 million gas boilers in the UK with 1.7million installed each year, mainly replacements, and around 11 million units sold annually worldwide. For domestic housing the retrofit market is the primary interest: 80% of the housing for 2050 has already been built. This presents both a massive opportunity both for emission reduction and for UK industry.”

Carbon is usually typecast as a villain in terms of the environment but researchers at the University of Warwick have devised a novel way to miniaturise a technology that will make carbon a key material in some extremely green heating products for our homes and in air conditioning equipment for our cars.

Most domestic heating and automotive air conditioning requires a lot of energy. Domestic space heating and hot water account for 25% of energy consumption in the UK. Across the EU, vehicle air conditioning uses about 5% of the vehicle fuel consumed annually, and within the UK it is responsible for over 2 million tonnes of CO2 emissions.

To combat global warming, new technologies to reduce these emissions are vital. Researchers at the University of Warwick have been working on practical solutions for many years and are now developing new energy saving technologies.

In houses, the best condensing boilers are about 90% efficient. There are electric heat pumps on the market that use electricity to extract heat from the outside air or the ground to heat homes more efficiently, but the electricity used still incurs large CO2 emissions at the power station. Researchers have long been aware of a much more energy efficient way to drive heat pumps (or air conditioners) using adsorption technology. This uses heat from a gas flame or engine waste heat to power a closed system containing only active carbon and refrigerant. When the carbon is at room temperature it adsorbs the refrigerant and when heated the refrigerant is driven out. A process which alternately heats and cools the carbon can be used to extract heat from the outside air and put it into radiators or hot water tanks. In the case of air conditioning it extracts the heat from the inside of the car. The major snag has been that adsorption technology to date would need to be roughly 300 litres in volume for a car air conditioner and larger for a heat pump to heat your house. Clearly that is not going to fit into a car and the volume of unit required for domestic heating probably couldn’t fit under your stairs at home either…

The Japanese space agency has unveiled an incredible new plan to start collecting solar power in space, and zap it down to Earth via microwaves or laser beams.


Under the plan, known as the Space Solar Power System (SSPS), floating photovoltaic dishes several square miles across would hover in geostationary orbit outside the Earth’s atmosphere as soon as 2030.

According to a researcher at Mitsubishi Heavy Industries, one of the project participants, “Since solar power is a clean and inexhaustible energy source, we believe that this system will be able to help solve the problems of energy shortage and global warming. The sun’s rays abound in space.” (Another picture after the jump).

To achieve this ambitious and highly futuristic aim, the Japanese government has recently chosen a consortium of companies and scientists charged with making the multi-billion-dollar dream of unlimited clean energy a reality in as little as 20 years. The team, called the Institute for Unmanned Space Experiment Free Flyer (USEF), also includes Mitsubishi Electric, NEC, Fujitsu and Sharp.

The plan is that the giant solar cells would harvest solar energy, which is at least five times stronger in space than on Earth, and beam it down to terra firma through clusters of lasers or microwaves.

Tadashige Takiya, a spokesman at the Japan Aerospace Exploration Agency (JAXA), told reporters that the beams would then be collected by gigantic parabolic antennae, most likely located in restricted areas at sea or on dam reservoirs.

At this stage, the consortium are hoping to create a one gigawatt system, equivalent to a medium-sized nuclear power plant, that would produce electricity at eight yen (nine cents) per kilowatt-hour, six times cheaper than the current cost in the country.

Tatsuhito Fujita, one of the JAXA researchers heading the project said that within several years, “a satellite designed to test the transmission by microwave should be put into low orbit with a Japanese rocket.”

The next step, scheduled for around 2020, is to launch and test a large flexible photovoltaic structure with 10 megawatt power capacity, to be followed by a 250 megawatt prototype.

Officials say that this would help evaluate the project’s financial viability, the final aim being to produce electricity cheap enough to compete with other alternative energy sources.

JAXA maintains that the transmission technology would be safe but concedes it would have to convince the public to accept the controversial plan, admitting that some may harbour images of laser beams shooting down from the sky, roasting birds or slicing up aircraft in mid-air.

According to a 2004 study by JAXA, the words ‘laser’ and ‘microwave’ caused the most concern among the 1,000 people questioned.

Ending uga_preg_callback: According to a 2004 study by JAXA Ending uga_filter:

The Japanese space agency has unveiled an incredible new plan to start collecting solar power in space, and zap it down to Earth via microwaves or laser beams.


Under the plan, known as the Space Solar Power System (SSPS), floating photovoltaic dishes several square miles across would hover in geostationary orbit outside the Earth’s atmosphere as soon as 2030.

According to a researcher at Mitsubishi Heavy Industries, one of the project participants, “Since solar power is a clean and inexhaustible energy source, we believe that this system will be able to help solve the problems of energy shortage and global warming. The sun’s rays abound in space.” (Another picture after the jump).

To achieve this ambitious and highly futuristic aim, the Japanese government has recently chosen a consortium of companies and scientists charged with making the multi-billion-dollar dream of unlimited clean energy a reality in as little as 20 years. The team, called the Institute for Unmanned Space Experiment Free Flyer (USEF), also includes Mitsubishi Electric, NEC, Fujitsu and Sharp.

The plan is that the giant solar cells would harvest solar energy, which is at least five times stronger in space than on Earth, and beam it down to terra firma through clusters of lasers or microwaves.

Tadashige Takiya, a spokesman at the Japan Aerospace Exploration Agency (JAXA), told reporters that the beams would then be collected by gigantic parabolic antennae, most likely located in restricted areas at sea or on dam reservoirs.

At this stage, the consortium are hoping to create a one gigawatt system, equivalent to a medium-sized nuclear power plant, that would produce electricity at eight yen (nine cents) per kilowatt-hour, six times cheaper than the current cost in the country.

Tatsuhito Fujita, one of the JAXA researchers heading the project said that within several years, “a satellite designed to test the transmission by microwave should be put into low orbit with a Japanese rocket.”

The next step, scheduled for around 2020, is to launch and test a large flexible photovoltaic structure with 10 megawatt power capacity, to be followed by a 250 megawatt prototype.

Officials say that this would help evaluate the project’s financial viability, the final aim being to produce electricity cheap enough to compete with other alternative energy sources.

JAXA maintains that the transmission technology would be safe but concedes it would have to convince the public to accept the controversial plan, admitting that some may harbour images of laser beams shooting down from the sky, roasting birds or slicing up aircraft in mid-air.

According to a 2004 study by JAXA, the words ‘laser’ and ‘microwave’ caused the most concern among the 1,000 people questioned.

In what could be a major breakthrough, Joule Biotechnologies announced that it has directly produced fuel from the plentiful carbon dioxide in the air around us using highly engineered photosynthetic microbes.


Inside specially designed reactors, Joule’s engineered microbes thrive off of sunlight and CO2. In return, depending on the type of organism, they can produce straight ethanol, diesel or a number of other types of hydrocarbons.

Although the process sounds similar to algae-produced biofuels, the Joule process is incredibly (and beneficially) different for several reasons:

  • Doesn’t produce biomass
  • No agricultural feedstock needed
  • Can be conducted on non-arable land
  • Doesn’t need fresh water
  • Produces fuel directly without the need for extraction or refinement

Apparently Joule has discovered some unique genes inside these microbes that produce the enzymes responsible for directly making the molecules found in diesel. From there, engineering organisms to make other fuels was a simple step. At this point, production of the fuels has only been done in the lab, but Joule has plans to open a pilot plant in early 2011.

uga_preg_callback: using highly engineered photosynthetic microbes. Ending uga_filter:

In what could be a major breakthrough, Joule Biotechnologies announced that it has directly produced fuel from the plentiful carbon dioxide in the air around us using highly engineered photosynthetic microbes.


Inside specially designed reactors, Joule’s engineered microbes thrive off of sunlight and CO2. In return, depending on the type of organism, they can produce straight ethanol, diesel or a number of other types of hydrocarbons.

Although the process sounds similar to algae-produced biofuels, the Joule process is incredibly (and beneficially) different for several reasons:

  • Doesn’t produce biomass
  • No agricultural feedstock needed
  • Can be conducted on non-arable land
  • Doesn’t need fresh water
  • Produces fuel directly without the need for extraction or refinement

Apparently Joule has discovered some unique genes inside these microbes that produce the enzymes responsible for directly making the molecules found in diesel. From there, engineering organisms to make other fuels was a simple step. At this point, production of the fuels has only been done in the lab, but Joule has plans to open a pilot plant in early 2011.

The Los Angeles Department of Water and Power (LADWP) has signed a lease for exploring geothermal potential in Imperial County near the Salton Sea; as part of meeting its goal to make 40% of its electricity from renewable sources by 2020.


It is offering to lease the land, initially for 5 years of exploration and study at $295,000 annually representing $100 per acre per year, under a MOU regarding “Imperial Valley Geothermal Feasibility and Exploration” while it determines the feasibility of geothermal production there.

A Secondary Term grants the option to extend the term for serial terms “for so long thereafter as Lessee continues to produce geothermal resources in commercial quantities from wells located on the property”.

LADWP is the largest municipal utility in the US; its membership consists of eleven cities and an irrigation district that supply electricity to Southern California, including the municipal utilities.

LADWP currently gets only 5% of its energy from renewable power, but is looking into expanding that very rapidly – to 40% by 2020. By contrast, Alameda Municipal Power already provides 56% renewable energy to  the Island of Alameda near downtown Oakland. 41% comes from geothermal, 9% from landfill gas and 6% from wind.

Sacramento’s SMUD makes 20% of its power from renewable sources, and it also encourages businesses and homeowners to make renewable energy by offering to buy it; and not just from solar and wind power, but it will also pay businesses that generate heat to capture it to make combined heat & power.

The Los Angeles Department of Water and Power (LADWP) has signed a lease for exploring geothermal potential in Imperial County near the Salton Sea; as part of meeting its goal to make 40% of its electricity from renewable sources by 2020.


It is offering to lease the land, initially for 5 years of exploration and study at $295,000 annually representing $100 per acre per year, under a MOU regarding “Imperial Valley Geothermal Feasibility and Exploration” while it determines the feasibility of geothermal production there.

A Secondary Term grants the option to extend the term for serial terms “for so long thereafter as Lessee continues to produce geothermal resources in commercial quantities from wells located on the property”.

LADWP is the largest municipal utility in the US; its membership consists of eleven cities and an irrigation district that supply electricity to Southern California, including the municipal utilities.

LADWP currently gets only 5% of its energy from renewable power, but is looking into expanding that very rapidly – to 40% by 2020. By contrast, Alameda Municipal Power already provides 56% renewable energy to  the Island of Alameda near downtown Oakland. 41% comes from geothermal, 9% from landfill gas and 6% from wind.

Sacramento’s SMUD makes 20% of its power from renewable sources, and it also encourages businesses and homeowners to make renewable energy by offering to buy it; and not just from solar and wind power, but it will also pay businesses that generate heat to capture it to make combined heat & power.
