They added single-walled carbon nanotubes to a film made of titanium-dioxide nanoparticles, doubling the efficiency of converting ultraviolet light into electrons when compared with nanoparticles alone. (MIT Technology Review; Mar. 05, 2007)
- Engines / Thermal Electric > New engine to slash 50% off emissions - Epicam's dexpressor concept would harvest wasted car exhaust heat to drive a pump-like rotor, improving engine efficiency, emissions and fuel economy up to 50 per cent. A heat exchange coil around the exhaust manifold of the engine super-heats water, building up pressure that is used to turn rotors that feed into the crankshaft of the engine.

- Oil > Oil innovations pump new life into old wells - Technology advances such as steam-flooding have made it possible to unlock more oil from old fields, and higher oil prices have made it economical for companies to go after reserves that are harder to reach. Forecasts that the world's reserves are drying out have given way to predictions that more oil can be found than ever before. (CNET News; Mar. 05, 2007)

- Secondary Oscillations > Milkovic-Berrett Secondary Oscillator Generator - Brian Berrett of Lehi, Utah has built a two-wheel device that uses the two-stage mechanical oscillator principle set forth by Mikovic. The electrical output from the secondary wheel is far in excess of the electrical input required to maintain the primary pendulum oscillation on the first wheel.

- Solar > Steven E. Jones Solar Funnel for Cooking - Prof. Steven E. Jones (of 9/11-demolition fame) presents a method for building a cooking device that is safe and low-cost, easy to make, yet very effective in capturing the sun's energy for cooking and for pasteurizing water. Requires cardboard, tin foil, black paint, and a mason jar.
- Batteries > Cymbet - High cycle, high energy density thin-film batteries have a very high discharge rate, do not lose power during storage, have unlimited recharge capability, stable chemistry and can be made in any shape or size. The POWER FAB™ battery is a flexible lithium cobalt oxide cell that uses a solid state LiPON electrolyte. Applications include consumer electronics, RFID tags, medical devices and semiconductors.
- Fusion > Practical Fusion, or Just a Bubble? - An overview of various approaches to useful fusion, including sonofusion, Eric Lerner's Focus Fusion, the $10 billion international Tokamac project. (NY Times; Feb. 27, 2007)
- Transmissions / Hybrid Vehicles > Van Cor Transmission - Symbiotic Drive runs both the gas engine and an electric motor at the same time in varied proportions to produce continuously variable output, an energy efficient process called “torque amplification�?. The two power sources are combined through a planetary system in which the electric motor can become an output generator when the gas engine is idling or when the vehicle is decelerating.
- Conservation > Space Heating > "Green Building" Electric Radiant Floor Heating - Speedheat® electric radiant floor heating produces energy savings up to 20% from heating only the occupied areas. It produces even heating from the ground up, with more comfort at lower temperatures, allowing reduced thermostat settings which also lowers heating costs. (PRWeb; Feb. 22, 2007)

- Power Systems for Future Exploration: STAIF 2007 - Energy-related abstracts from the 2007 STAIF Conference posted by Tim Ventura at AmericanAntigravity.com. STAIF allows industry, government, and universities to share their latest achievements.
- Reverse Engineering > UFO science key to halting climate change - A former Canadian defense minister is demanding governments worldwide disclose and use secret alien technologies obtained in alleged UFO crashes to stem climate change. Alien spacecrafts would have traveled vast distances to reach Earth, and so must be equipped with advanced propulsion systems or used exceptional fuels. (Yahoo News; Feb. 28, 2007)
- Biomass > World Sustainable Energy: biomass pellets - Biomass fuel pellets are a clean, CO2-neutral and convenient fuel made from wood chips, forestry residues or woody energy crops. Biomass has become directly competitive with fossil fuels in Europe, where highly efficient combined heat-and-power (CHP) biomass plants have replaced an increasing amount of coal and oil. (Biopact; Mar. 1, 2007)
- Solar > Portable “micro utilities�? powered by renewable energy - Ecos LifeLink folds out of a shipping container to meet the demand for off-grid water, energy and communications. It has 16 kW of photovoltaics, an optional wind turbine, a wireless communications control center with a range of 30 miles, and can filter 30 gallons per minute of contaminated ground water. (TreeHugger; Mar. 2, 2007)
- Solar Heating / AC > Solar Air Heating and Cooling - The Sun Lizard heats the air, and then uses a fan to pump that air around the building to keep people warm in winter. In summer the fan is used as a heat extractor, pulling rising heat from the building and venting it outside. It retails at $2500 but mass production may reduce the cost.

- EV > Electric Cars > Quanxing Transport Equipment - The Current 4 passenger electric car can go 120 km per charge with a top speed of 45 km/h. It will be imported to the U.S. by Electric City Cars with a target price of under $13,000.
- EV > Electric Cars > Vstar Group Vehicles - The Vstar 2 seater electric city car from China has a range of 100 km and a maximum speed of 58 km/h. This all electric alternative to the Smart Car will be imported by Electric City Cars.

- Alt Fuels > Butanol > EPA Awards SBIR Contract for Butanol from Biomass - The US EPA will award a contract to Integrated Genomics to develop an economically competitive biobutanol production method. In 2004, the EPA awarded a contract to CPBR to develop a two-step fermentation process for production of butanol, that runs through September 2007. (Green Car Congress; Mar. 1, 2007)
- Batteries > Pee Powered Battery - Scientists soaked a piece of paper in a solution of copper chloride, sandwiched it between strips of magnesium and copper and laminated it in plastic. When a drop of urine is added to the paper through a slit in the plastic, a chemical reaction takes place that produces about 1.5 volts of electricity, the same as a standard AA battery, for about 90 minutes. (TreeHugger; Mar. 1, 2007)
- Biomass > Harvesting algae blooms from the open ocean - AlgoDyne Ethanol Energy has developed a new process to harvest biomass from marine algal blooms, that occur in almost all oceans of the world, often caused by man-made nutrient pollution. It could yield huge amounts of biomass usable for ethanol and biodiesel production at virtually no cost. (Biopact; Mar. 1, 2007)
- Fuel Efficiency > Transmissions > Van Cor Transmission - Allows changes in gear ratios without interruption of torque based on conic gears. For automotive applications, the VCT would improve fuel economy compared to stepped-gear-ratio transmissions.
