Directory:Wind > Directory:Vertical Axis Wind Turbines > Directory:Gual Industrie StatoEolien Vertical-Axis Wind Turbine - The power curve of this French design is surprisingly different than power curves for conventional turbines because the output increases until the velocity of the wind is above the lower hurricane levels.
Directory:Fuel Efficiency > Directory:Fuel Efficiency Retrofits / Directory:Engines > EnviroFit - Cleaning up the air in the developing world by retrofitting up to 2 million two-stroke powered vehicles with cleaner, more efficient direct injection technology licensed from Orbital Corp. The upgrade eliminates 90% of hydrocarbon and 70% of carbon monoxide emissions while improving fuel economy more than 30%.
Directory:Electromagnetic > Synchro Pulse - High efficiency brushless motor technology utilising an innovative approach to the magnetic engineering inside the motors, delivering more load for less electricity without requiring exotic materials or unusual production techniques. The motors use much less electricity for a given load and the speed controller ensures you never deliver more power than needed.
Directory:Stirling Engines / Directory:Home Generation:Space Heater > Thermal Engine Corporation - The Heat Wave Stirling-cycle stove fan for wood/pellet stoves is placed directly on top of a hot surface and circulates the warm air using only the heat radiated by the stove as its power source. It increases stove heating efficiency by up to 35% and will run indefinitely while atop a hot surface while not costing a penny to operate.
Directory:James Dunn / Directory:Solar > Directory:Silicon > Solar Silicon Solution Wins MIT Energy Plan Contest - RSI Silicon debuts a far more inexpensive method of producing solar grade Silicon, winning "Poeple's Choice" award and first place in the Energy Business Plan contest held by MIT. (PESN May 2, 2007)
Directory:Fuel Cells > PAC Zinc Air Fuel Cells - Power Air Corporation's Zinc Air Fuel Cell offers an alternative to batteries, generators, and hydrogen fuel cells, producing zero emission energy for portable, stationary, light mobility, and transportation applications. ZAFC technology is low cost with all the advantages of batteries and engines, without the disadvantages. (The Energy Blog May 2, 2007)
Directory:Electric Vehicles / Directory:Solar:Vehicles > Solar Trike - The Sun-E-Trike solar powered recumbant bike is a low cost alternative to an automobile that is fun and easy to ride, street legal, and no license is required. It goes 13 to 32 mph with a 10 to 25 mile range and under average use is maintenance free.
Directory:Fuel Efficiency > Directory:Fuel Efficiency Retrofits > Sonic Spark Plugs - They look like normal spark plugs, but they have a powerful ultrasound generator in the tip. This shatters gasoline mist microseconds before it burns, energizing the fuel droplets before combustion. Your car, truck or motorcycle will have more power and get better mileage because combustion is dramatically improved.
Directory:Clean Coal > Fuel Tech - FUEL CHEM® programs can improve the efficiency, reliability and environmental status of plants operating in the electric utility, industrial, pulp and paper, and waste-to-energy markets. Products include customized NOx control systems, which can reduce emissions from 30% – 85%, treating a wide variety of solid and liquid fuels, including coal, heavy oil, biomass and municipal waste.
Directory:Transmissions > Directory:NuVinci CVP > Fallbrook to Develop CVT for Outdoor Power Equipment - Fallbrook Technologies and Aftermarket Technology Corp. will develop a continuously variable planetary (CVP) drivetrain for ATVs, garden tractors, and utility vehicles, based on Fallbrook's NuVinci technology. It is more efficient, produces less heat and noise, performs better on hills, and is much easier to package. (The Auto Channel May 1, 2007)
Directory:Batteries > Directory:EEStor / Directory:Feel Good Cars > ZENN Motor Company Invests in EEStor - ZENN Motor Company has an option for additional investment, following EEStor's successful completion of permittivity (electrical storage capacity) testing of its high-power-density ceramic ultracapacitor (EESU). The EESU could potentially allow ZENN vehicles to go as far and as fast as a traditional car at a fraction of the cost. (Green Car Congress Apr. 30, 2007)
Directory:Wind > Directory:Vertical Axis Wind Turbines > New Rooftop Wind Turbine Tested - The Helyx Wind Generator is composed of two twisted wings of bright green fiberglass that rotate around a vertical axis, designed to take advantage of low wind speeds, with an estimated production cost of $1.50 per watt. The 40-inch tall turbines will be tested on the rooftops at Portland State University, to see if they adequately harvest energy in an urban environment. (MetaEfficient)
Directory:Conservation > Smarty Pants Energy Monitor - The Home Joule energy data display device receives real-time info about your local utility, time-of-day energy costs, and local weather, then splices this with your home energy consumption. It helps consumers make informed decisions to reduce energy use. (TreeHugger May 1, 2007)
