Now there’s a mouthful.  A relatively unheralded study released nearly two years ago by scientists at UC Berkeley explains the significance of this phenomenon on forests and climate.  In a report on the UC Berkeley news website entitled “Deep-rooted plants have much greater impact on climate than experts thought,” hydraulic redistribution is defined as the [...]

Last week we reported on a photovoltaic powered car, today we feature a company that is manufacturing photovoltaic powered lighting.  Founded not quite two years ago by Sam Goldman, d.light Designs intends to sell affordable, clean lighting to households that currently rely on kerosene for illumination.

Better light equals better health and
better education. Initially, d.light
will distribute their lights in [...]

Once in a while you run across something that challenges just about everything you thought you knew.  “Terra preta” (Portuguese for “black earth”) are anomalous deposits of deep, rich soil found in large pockets of land throughout the Amazon.  Once thought to be 100% comprised of thin, fragile soil that would immediately desertify if the trees were removed, [...]

If you had 100 square feet of photovoltaic panels (PV), at 10 watts per square foot (full sun only), then you would be able to save one kilowatt-hour per hour. For that matter, if you only had 50 square feet of PV, but your panels yielded 20 watts per square foot in full sun, you [...]

There are few ways to better illustrate the folly of ignoring thermal factors over atmospheric factors when prescribing global climate mitigations than this:  There are alternative energy technologies that will exploit cold conditions to offload heat.  Put another way, it is now cost effective to extract cold thermal mass from the deep waters of lakes [...]

Here comes another all-electric automaker, and one with quite a pedigree.  If you go to the website for Fisker Automotive you will be tantalized but definitely not overwhelmed with information.  Like Aptera, this Southern California start-up is keeping a low profile as their next generation car takes shape.  On Fisker’s home page you will see a sexy green silhouette [...]

Will we ever see fuel cell cars on the road?  Many critics feel that government support for this technology is misguided, with far better options available for alternative-fuel, “green” transportation. While the fuel cell concept is simple, implementation faces major hurdles. For example, there are more than 170,000 gas stations in the United States and so far [...]
