Plasma Gasification turns trash into clean energy

June 07, 2007 - 01:43:55 PM

From the Star Tech Environmental Corp. website:

Startech Environmental is an environment and energy industry company engaged in the production and sale of its innovative, proprietary plasma processing equipment known as the Plasma Converter System(TM). The Plasma Converter System safely and economically destroys wastes, no matter how hazardous or lethal, and turns most into useful and valuable products. In doing so, the System protects the environment and helps to improve the public health and safety. The System achieves closed-loop elemental recycling to safely and irreversibly destroy Municipal Solid Waste, organics and inorganics, solids, liquids and gases, hazardous and non-hazardous waste, industrial by-products and also items such as "e-waste," medical waste, chemical industry waste and other specialty wastes while converting many of them into useful commodity products that can include metals and a synthesis-gas called Plasma Converted Gas (PCG)(TM).

Among the many commercial uses for PCG, is its use to produce "green electrical power," Gas-To-Liquid (GTL) fuels such as ethanol, synthetic diesel fuel and other higher alcohol "alternative" fuels. Hydrogen, for use and sale, can also be separated and recovered from the PCG synthesis gas mixture.

The Startech Plasma Converter is essentially a manufacturing system producing commodity products from feedstocks that were previously regarded as wastes. Startech regards all wastes, hazardous and non-hazardous, as valuable renewable resources. Popular Science Magazine, in its March '07 produced a 9-page, well-illustrated feature article on the Startech Plasma Converter as the "Miracle Energy Machine -- How to Turn Toxic Waste into Clean Power."

Home hydrogen fueling station

June 07, 2007 - 02:12:50 PM

From the Business 2.0 website:

What could be cooler - or greener - than a hydrogen car in your driveway? Try a solar-powered hydrogen fueling station in your garage. Scientists in Melbourne, Australia, have developed a prototype of such a device. It's about the size of a filing cabinet and runs on electricity generated by standard-issue rooftop solar panels.

The first version of the home fueling station is expected to produce enough hydrogen to give your runabout a range of some 100 miles without emitting a molecule of planet-warming greenhouse gas. Road trips are out of the question, but it's enough juice for running suburban errands or powering fleets of urban delivery trucks.

This week, HP announced the greenest computer ever – the RP5700, and was awarded the first “gold” rating by EPEAT. How does HP make it to gold? First, by redesigning for end of life – 95% of components are recyclable, and the internal chassis can be taken apart by hand with no need for special tools for easy disassembly. Toxic and hazardous materials have been eliminated to meet the EU’s tight regulations, and both the plastic casing and external cardboard packaging source a percentage of post–consumer waste.

Animated Parody of The Da Vinci Code

June 19, 2007 - 08:00:49 PM

The Bio DaVersity Code is an animated parody of the The Da Vinci Code. It is part of an on-line awareness campaign to alert people that we must sustain all life in order to sustain human life.

If current trends continue, half of all species of plants and animals living today may be extinct in less than 100 years. Unless halted, this catastrophic loss of biodiversity will radically alter our children's prospects for health and safety.

By all measures, its an issue which has already reached crisis proportions but has yet to reach a tipping point of public concern like global warming.

Concentrating the Sun's Light a 1000 X

June 21, 2007 - 08:29:25 AM

Professor David Faiman and his collegues at the Jacob Blaustein Institutes for Desert Research, Ben-Gurion University of the Negev are convinced that the feasibility of realizing concentrator photovoltaic (CPV) systems on a very large (state-wide) scale is imminent. They outline the economic feasibility of an approach using existing proven technology in a paper referenced below. Their economic financing model developed by D. Raviv was based on technology developed by Amonix Inc.

But Faiman has developed what he considers a breakthrough technology that utilizes a 400 square meter (4,300 sq ft) solar concentrating dish capable of achieving 1000 suns (concentration the intesity of the suns energy by a factor of 1000). The dish is lined with 216 triangular mirrors and is supported by a geodesic structure that rotates and tilts according to the position of the sun.

The dish focuses the 1000 X light on a single 10cm x 10cm PV panel and according to latest test results can produce more than 1.5 kW at 15 % effeciency under field operating conditions without visible signs of damage or degradation.

The big improvement comes not with power conversion effeciency but with power out put per square centimeter. In this case were talking about a power generation increase hundreds of times greater due to the effeciency of the concentrating dish. This ultimately translates to the ability to build a large power plant utiliizing less land for the giant dishes and far fewer of the expensive PV panels.  READ MORE »
