So You Want Electric Cars??

The Universal Automobile (UA) is a "public domain" vehicle used by subscribers; it is powered by batteries which can be automatically trickle-charged using "charging mats" deployed across preferred downtown locations designated as "UA Parking Areas" , or alternatively, their batteries can be quickly exchanged at traditional gasoline stations converted to accommodate automatic "swapping"..

There Is No Global Fresh Water Issue

Zonnewater developed a desalination unit based on solar energy (95% thermal and 5% photovoltaic or wind energy), suited for coastal areas with an average temperature of 30 degrees Celsius. The prototype is a small one cubic meter greenhouse-type construction that produces 40 litres of water per day.

VEGGIEBENZ

The engine is running smoother, quieter, and although veggie is supposed to have 6% less BTU, performance and mileage do not seem to be affected. Emissions definately have been affected positively. No black smoke and the exhaust smells better.

Water Wisdom

Grey water reuse offers a wonderful opportunity for us to maintain the sort of gardens we want, without wasting a single drop of precious drinking water.

Combining The Sun's Heat And Light Could Boost Water-Splitting Efficiency

Using the sun's heat and light together could be an efficient way to produce hydrogen, which in turn could be used to power cars, homes and businesses.

Education In Construction: Cat Announces The Wise Project

The project aims to minimise environmental impacts both during construction and during occupancy. Current best environmental practice in building is the BREEAM criteria - The Building Research Establishment Environmental Assessment Method.

IS 'CLEANER AND GREENER' TECHNOLOGY A Sufficient Solution To Our Sustainability Problem?

A Company that adopts a strategy of technological reform does not necessarily have to confront its unsustainable principles and priorities. It is not hard to imagine, for example, a company that replaces its gas-powered buses with electric ones, while continuing to use them to transport exploited workers to sweatshop factories.

Living Off The Grid

The charge for connecting to the grid would have amounted to $125,000., whereas the total cost for the Renewable Energy system was $25,000., - a savings of $100,000!

NEW ENERGY BILL: Reducing Our Dependence On Foreign Oil

The lion's share of oil consumption stems from transportation needs. In 2002, the transportation sector accounted for about 68% of total petroleum use with gasoline accounting for two-thirds of the petroleum consumed in the transportation sector.

One Year After The Big Blackout Alternative Energy Makes Gains

As last year's blackout showed, whenever what we know and trust fails us, we immediately seek out the alternatives. Which meant that stocks in alternative energy companies spiked significantly in the days following the blackout.

Reliable Pitching: Ultracapacitors And Wind Turbine Pitch Systems

Ultracapacitors prove to be a high-reliability solution for the severe power pulses needed for wind turbine pitch control.

WHAT AMERICA NEEDS NOW

"We are like tenant farmers chopping down the fence around our house for fuel when we should be using Nature's inexhaustible sources of energy - sun, wind and tide. I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." - Thomas Alva Edison (1847 - 1931)

Coming In Out Of the Cold: Hybrids Put To The Test

Some of the questions we have for hybrid technology are now dependability in cold weather starting, reliability in highway driving standards, added to these ever so alluring fuel cost savings.

Fresh Outlook On Fresh Air

Solarwall is a solar, fresh air, heating and ventilation system

Learn To Conserve

If you want to have a renewable energy system you need to learn to conserve well in advance of buying the system.
