From the GreenBuild show in Boston to the International Builders' Show in Las Vegas, green building products are taking center stage: From a vertical wind turbine you can actually buy (but maybe not afford) to a compact CFL that looks just like a light bulb, here are a few recent highlights.
HelixWind Vertical Wind Turbine: While the price tag might not be as attractive as the design, the HelixWind vertical wind turbine can generate about 9,500 kW hours per year at an average wind speed of 10 mph and only measures 10 feet tall.
GE: Compact CFL: Most of our readers probably have plenty of CFL's already installed but I'm guessing that there are a few lamps or recessed lights where CFL's haven't worked out because of size. GE has solved this problem by miniaturizing the electronics in the their new bulbs allowing them to fit pretty much anywhere an incandescent can fit.
Bushman: Rain Harvester: Bushman's new rain harvester is similar to those we've seen (like the HOG) but is a complete system with connectors, filters and a pressure pump. They come in sizes from 130 gallons up to 2,825 gallons.
Laing: Power-Sipping Circulating Pump: According to ThisOldHouse, the average household sends 17,000 gallons of clean water down the drain while waiting for hot water to travel from the water heater to a faucet or shower head. Circulation pumps have been around for a while and are slowly making their way into homes across the country. The pump works by circulating hot water through your pipes so it's there whenever you turn on the pipe. While these aren't good for heat-on-demand systems, they are good for conserving water on standard water heaters. Laing's new Ecocirc E-series pump consumes a paltry 12 watts per hour to conserve electricity and water.
