        - Xtrac will exploit Torotrak’s full-toroidal traction drive to develop highly efficient CVTs for use in the new kinetic energy recovery systems (KERS) proposed for F1 motor racing. The system holds promise for use in road cars, storing kinetic energy in a flywheel, boosting fuel economy without complex electrical-battery hybrid architectures.

        - UTC Power commercial fuel cell power systems are being used by Hilton hotels for combined heat and power (CHP) applications. The PureCell™ is fueled by natural gas to produce 200 kW of electric power, plus about 900,000 Btu/hr of heat, and is nearly 3x more energy efficient than the electric grid when used in CHP applications, the company claims.

        Industry Turns Violent and Bloody in Colombia
        - Armed groups in Colombia are driving peasants off their land to make way for plantations of palm oil, a biofuel that is being promoted as an environmentally friendly source of energy. Surging demand for "green" fuel has prompted right-wing paramilitaries to seize swaths of territory, according to activists and farmers. (TruthOut; June 5)

        - Stabilized enzyme biofuel cells (SEBC™) offer increased performance and lower costs through the use of renewable resources that also provide environmentally friendly disposal. By elimination of metal catalysts they can potentially double the amount of fuel converted into electricity, dramatically increase fuel cell energy density, and at the same time lower cost.

      • Peak Oil > Lindsey Williams - The Energy Non-Crisis - Eight-part video series (90 min total) by former chaplain of the Alaskan North Slope pipeline crew starting in 1974. His executive status gave him access to information about the vast oil wealth in Alaska being covered up by a cabal set out to benefit from U.S. dependence on Middle East oil.

        - Mini-power plant is simple to construct, has a turbine efficiency of 80% but is safe for fish due to low turbine speed. The gravitational vortex hydro technology can be applied with water drop as little as 0.7 meters. The cost for installation of the prototype was close to $1/watt capacity. (TreeHugger; Jun. 2, 2007)
      • Solar > Thin Film > SoloPower - Electrochemistry based CIGS technology will enable production of high efficiency solar cells at a fraction of the cost of traditional CIGS fabrication methods, built on a thin flexible foil substrate. The total thickness of the active layers is in the order of 2 micrometers, resulting in efficient use of materials without negatively impacting the conversion efficiency. (Thanks John Q. Public)

        - The Dynalifter® “Roadless Trucking” system has transport costs and speeds comparable to trucking without the need of building a sophisticated highway network. It has the ability to fly on low amounts of power at low speeds, much like airships, but without the operational drawbacks of a traditional airship. (Thanks John Q. Public)

        - A group of Brigham Young University students have found that fuel does grow on trees - and it may help save a faltering island economy. The students created a formula that takes 10 coconuts mixed with methanol and sodium hydroxide to produce a liter of diesel fuel with a byproduct of glycerin, which can be made into soap or compost.

        - VIVACE (Vortex Induced Vibrations Aquatic Clean Energy) extracts energy from ocean, river, tidal and other water currents over a wide range of current speeds. It is non-obtrusive, environmentally friendly, and has an extremely high energy density (50x less acreage required than wave power). A working prototype has met expectations, leading to a multi-kilowatt field demonstration. (Thanks John Q. Public)
      • Solar > Space solar power: limitless clean energy - Solar power from both the Moon and from satellites would provide energy for operations in space and could be beamed down to Earth using either lasers or microwaves, with 24 hours production every day of the year. Most of the technologies needed are already being developed by NASA. (The Space Review; May 14, 2007) (Thanks John Q. Public)
      • Solar > 40% efficient solar cells milestone achieved - Scientists from Spectrolab, Inc., a subsidiary of Boeing, have fabricated solar cells that divide the broad solar spectrum into three smaller sections by using three subcell band gaps. Each of the subcells can capture a different wavelength range of light, enabling each subcell to efficiently convert that light into electricity. (PhysOrg; June 1) (See Slashdot discussion) 
      • Fuel Efficiency / Clean Coal > Jupiter Oxygen - Oxy-Fuel Combustion Technology is a method/process in which oxygen is used with fossil fuel [coal, oil, natural gas] while air is excluded, reducing fuel usage up to 73%. NOx emissions are greatly reduced without any back-end emissions control technology and CO2 becomes highly concentrated, making capture easier and more economical. (Thanks John Q. Public)

        - The patent-pending turbine for wind and water, invented by Phi Tran, employs lift on the leeward edge, harnessing the turbulence that usually impedes efficiency. The price point is expected to be better than fossil-fuel-generated electricity, even in low wind areas, making it ideal for city/urban roof top and back yard settings. (PESWiki; May 31)

        - Solar Electrical Vehicles is adding a convex solar roof to hybrid cars like the Toyota Prius, to charge a supplemental battery. With the solar roof, the Prius can operate up to 20 miles per day in electric mode, improving fuel economy up to 29% at a cost of $2000-$4000. The company is also looking at ways to add the technology to electric Teslas. (TreeHugger; May 31, 2007) (Thanks John Q. Public)

The company plans to then sell the oil to others, or as last resort, to refine it itself. Avoiding costly bioreactors and genetically modified algae, the company plans to grow vast amounts of biomass very cheaply in open ponds. (Inside Greentech; May 31, 2007) (Thanks John Q.
