  • Fusion > Inertial-Electrodynamic Fusion Device - Dr. Bussard and his team at Energy/Matter Conversion Corporation, after close to 20 years of hard work, have developed a revolutionary radiation-free fusion process that takes boron-11 and fuses a proton to it, producing, in its excited state, a carbon-12 atom. This excited carbon-12 atom decays to beryllium-8 and helium-4. It was developed under a DOD contract and has recently been made public.
  • Storage > Energy Storage and Power Corporation - ESPC developed a Compressed Air Energy Storage (CAES) plant based on Dry Air Injection that reduced plant costs by more than 50%. It is a cost effective way to store hundreds of MW’s of off-peak electric energy from coal, nuclear or wind power plants underground and make it available during peak electric hours.
  • Hybrid Vehicles > TNO Hybrid Carlab - This Beetle finished 2nd in the 2005 Rallye Monte Carlo for Hybrid Vehicles using < 4 litres/100km (59 mpg US). A 150kW AC Propulsion electrical system powers the front wheels supplied by a VW 1.2 TDI 3-cylinder diesel engine and UQM generator. Peak power is supplied by a supercapacitor pack consisting of 3500F Nesscap cells.
  • Zeitgeist / Biomass > Biomass: Year-in-Review - Large VC investments, new leadership, increased acceptance from the environmental community, national security threats and unstable energy markets sparked the country's enthusiasm for biomass. The industry's capacity to ramp up production and the ability of this renewable resource to provide a considerable quantity of power, not just liquid fuel, has made biomass a significant player in the U.S. energy future. (Renewable Energy Access; Jan. 2, 2007)
  • Alternative Fuels > Biomass > Mascoma - Cellulosic biomass has a cost per BTU equivalent to oil of about $14/barrel. Recent advancements in enzymes, organisms and production technologies allow cost-effective ethanol production from inexpensive cellulosic biomass (grass, wood, agricultural and forestry wastes).
  • Tidal > Video of Underwater Turbines Being Installed - The New York Times has a video of the installation of two turbines near Roosevelt Island in New York City- one is a test device to monitor fish and conditions, the other generating power. Tide-powered underwater turbines look like windmills, but use tidal currents to make electricity. (TreeHugger; January 2, 2007)
  • Alternative Fuels > Butanol > Biobutanol - The Other White Meat - David Ramey drove his unmodified 1992 Buick across America fueled by 100% butanol. It can be blended with gasoline in larger concentrations than ethanol, yields 104,800 BTU/gallon vs. 84,250 BTU/gallon for ethanol, burns cleaner than E85, is less corrosive, evaporates slower than ethanol and can be transported through existing pipelines.

  • Nanotech > Nano Safety Alert - Decades of research have brought these materials to a stage where they can provide real value to the world, including several energy applications. However, worker safety, consumer health, and the environmental impacts of such materials have to a large degree been ignored. (MIT Technology Review; Jan. 2,. 2007)

  • Electric Vehicles > Nova Technologies Pursuing Self-Charging Vehicle Technology - Institute claims to be developing a "self-recharging electric vehicle, capable of converting ambient energy sources into usable electrical power efficiently enough to power a 1,500 pound vehicle at highway speeds for unlimited distances without the combustion of any kind of fuel or emission of any exhaust." (PESN; Dec. 30, 2006)

  • Hydrogen / Electrolysis > High Pressure > Accagen Pressurized Electrolyzers - AccaGen has developed special electrolyzers with maximum efficiency (>85%) for energy storage in renewable energy systems applications like Sun, Wind, Hydro. Direct-to-pressure process avoids the necessity of using costly, maintenance intensive and energy consuming gas compressors.
