Not exactly washing without water, but with less than 2% of a normal washing machine. That’s only 1 cup of water for those sweaty gym clothes, grubby kid-wear, and foul socks.
Washing with soap and water has been THE WAY to clean most clothes for so long, it’s hard to imagine reducing H2O by 98%. What this technology lacks in sexy bells and whistles, it gains in implications. Billions of gallons of clean water could be conserved every year simply by adopting this dry cleaning technology. Less water also means less drying, which can add energy savings to those with energy-hungry clothes dryers.
Editor’s note: Many investors see clean technology as a smart bet these days… but how do you get your cleantech business plan in front of the people with the money? Lead Edwards at Ecopreneurist points to one source of advice for clean/green entrepreneurs: universities… and some of this advice is free. This post was originally published on Monday, March 31, 2008.
If you are a scientist or researcher with a great idea for a green business, you should check out what universities have to offer you (even if you are not in school).
As an example of the types of programs available, consider UC Davis’s Green Technology Entrepreneurship Academy (GTEA), which provides a free, week-long intensive for science and engineering researchers. Yes, I did say free, and it’s held at Lake Tahoe, Nevada in July—a very nice plus.
According to UC Davis Center for Entrepreneurship Assistant Director, Nicole Starsinic, the GTEA combines classroom learning with a team project, which pairs scientists with business school students and professionals. A number of venture capital firms, law firms, and other professionals, which are listed in the Academy’s schedule, devote time in the hope of discovering the cleantech Google.
What if you could produce clean solar energy night and day, rain or shine, and never hit the bank for a single P.V. solar panel? Photo voltaic panels can be pricey, so the solar industry is always trying to lower costs and boost efficiency in the quest to compete with coal. One fast-growing, cost-effective solar technology uses heat to generate energy 24 hours a day, and it can store energy without batteries. In this post I’m going to investigate solar-thermal technologies.
It’s called “Concentrated Solar Power” or C.S.P. The idea is simple; no complex chemistry or fancy silicon wafers required. Glorified mirrors shaped like satellite dishes (or parabolic troughs) direct the sun’s rays towards a reservoir. The concentrated solar heat boils water into steam, and steam powers a turbine. When the water cools off it’s collected and cycled back through the system. The mirrors can even track the sun across the sky to maximize efficiency. Water is not the only fluid that can be used, but its unique properties have made it popular. More on that below.

Baking soda: It's like magic powder. It can be used everywhere, and once you start utilizing it for all of its 101 uses, you just might get pretty attached to this stuff.
