US Energy Commission Chair: “No Need for More Nuclear or Coal Plants Ever”

Written by , on April 26, 2009

John Wellinghoff, the Chairman of the U.S. Federal Energy Regulatory Commission has told a U.S. Energy Association forum.that no new nuclear or coal plants may ever be needed in the United States, "We may not need any, ever," Mr Wellinghoff said. Renewables like wind, solar and biomass will provide enough energy to meet baseload capacity […]  Read more »

Is “Cold Fusion” Real?

Written by , on April 21, 2009

In 1989, Martin Fleischmann and Stanley Pons anounced that they had demonstrated the production of excess heat during electrolysis with palladium cathodes in heavy water. The phenomenon was dubbed "cold fusion" and their claims were quickly dismissed. However, many laboratories have since repeated their expeiments. Although most have failed, a few have reported success. A […]  Read more »

“New” Nuclear – Helium-3

Written by , on October 26, 2008

“Conventional” nuclear fusion reactors work by fusing deuterium and tritium to produce helium-4, a neutron and enormous heat and radiation. The heat is used to boil water and the resulting steam drives a turbine. Several experimental nuclear fusion reactors based on this principle have been built but none has yet produced more power than it […]  Read more »

“New” Nuclear – Thorium

Written by , on October 25, 2008

In a conventional nuclear reactor the input fuel is uranium-235 (U-235) which is part of a much larger mass of uranium – mostly U-238. This U-235 is progressively “burned” over about three years to yield a lot of heat. This fission of U-235 causes some of the U-238 to turn into plutonium-239, which behaves almost identically to […]  Read more »

Prototype Fusion Reactor

Written by , on October 6, 2008

British scientists at the Rutherford Appleton Laboratory near Oxford will this week begin work to create a nuclear fusion reactor. If successful, the reactor will be a prototype for future commercial power stations, providing a cleaner and safer replacement for conventional nuclear power stations with the potential of producing effectively unlimited energy. The fusion reaction […]  Read more »

Cost of Nuclear Power Soars

Written by , on May 16, 2008

According to a report in todays Wall Street Journal, the cost of building nuclear power plants is increasing even faster than the price of petrol.  Although no nuclear power plant has been built in the United States since the seventies, several are now on the drawing board because of the steep rise in fossil fuel […]  Read more »
