WHY A HYDROGEN ECONOMY DOESN'T MAKE SENSE, December 11 In a recent study,
fuel cell expert Ulf Bossel explains that a hydrogen economy is a wasteful
economy. The large amount of energy required to isolate hydrogen from natural
compounds (water, natural gas, biomass), package the light gas by compression or
liquefaction, transfer the energy carrier to the user, plus the energy lost when
it is converted to useful electricity with fuel cells, leaves around 25% for
practical use - an unacceptable value to run an economy in a sustainable future.
Only niche applications like submarines and spacecraft might use hydrogen.

MILEAGE FROM MEGAWATTS: STUDY FINDS ENOUGH ELECTRIC CAPACITY TO 'FILL UP'
PLUG-IN VEHICLES ACROSS MUCH OF THE NATION, December 11 If all the cars and
light trucks in the nation switched from oil to electrons, idle capacity in the
existing electric power system could generate most of the electricity consumed
by plug-in hybrid electric vehicles. A new study for the Department of Energy
finds that "off-peak" electricity production and transmission capacity could
fuel 84 percent of the country's 220 million vehicles if they were plug-in
hybrid electrics. Full story at http://www.physorg.com/news85067531.html
SUSTAINABLE NUCLEAR ENERGY MOVES A STEP CLOSER, December 11 In future a new
generation of nuclear reactors will create energy, while producing virtually no
long-lasting nuclear waste, according to research conducted by Wilfred van
Rooijen, who will receive his Delft University of Technology (Netherlands) PhD
degree based on this research subject on Tuesday, 12 December. Full story at
