NEW YORK, NY April 05, 2007 —Approximately 14 percent of all electrical power in New York State comes from hydropower. Many environmentalists believe that figure should be higher. They see hydropower as a way of reducing our reliance on the fossil fuels that contribute to global warming. In our ongoing series on how the New York region is preparing for climate change, WNYC’s Beth Fertig looks at one small company that’s now experimenting with a new form of hydro-electric power right in the East River.
CORREN: The turbines actually turn very slowly. They’re five meters in diameter - that’s 16.4 feet - and they turn at about 34 RPM. Quite stately is my term for it. Also leading edges are very rounded and blunt. Also the inner part turns very slowly. So there’s only a very small area that could actually hurt fish if they were to hit it.
REPORTER: And those tests are just beginning. In a former shipping container that’s been turned into a control room, Verdant has spent several months already studying the habits of East River wildlife. Analyst Hannah Abend uses her computer to look at underwater images captured by a different sonar device last year.

Waste-to-Energy Plants Could Replace Incinerators

LONDON, Apr. 2, 2007 -- Cutting edge waste-to-energy plants that are smaller and cleaner than incinerators could soon hit the U.K. market, ending the need for polluting incinerator projects.
The plants run a new process that transforms non-recyclable waste into a clean syn-gas, used to generate clean power and a high-strength building material, with the plant itself powered by the syn-gas it produces.
Carbon-neutral and very low in emissions with plants around a third of the size of incinerators, the Gasplasma process can compete with incinerators on a number of counts, according to Andrew Hamilton, CEO of Advanced Plasma Power, the company that patented the process.
'The trick here for us has been the combination of gasification and plasma. The benefit of combining these two existing technologies is that you substantially reduce the power requirements, and that transforms the economics of the process,' Hamilton said.
'You will get some CO2 coming out but a half to two-thirds of the waste is biodegradable, so it's carbon neutral,' he said, adding that the process beats incineration when it comes to the carbon balance.
The process has passed tests in a pilot plant with flying colors and is now ready to be implemented on larger scale, he said. Numerous advantages over incinerators include size, a major selling point as the 50-foot-high plant takes up around a third of the space needed for an incinerator.
'Because it's got a small building footprint with a low profile building and small stack, and it's very clean, it is very suitable for urban"
