$25-million prize to clean up the air

From Times Wire Reports

Airline tycoon Richard Branson announced Friday that he would award a $25-million prize to the first person to come up with a way of scrubbing greenhouse gases from the atmosphere and alleviate global warming.

The prize will initially be open for five years, with ideas assessed by a panel of judges. The winning technique must remove 1 billion tons of carbon gases a year from the atmosphere for 10 years -- with $5 million going to the inventor at the start and $20 million at the end.
