A renewable energy concept I had not heard of before. Gases
rising in a solar heated chimney turn turbines. A bank of solar
cells store energy so the tower can operate 24/7. The tower would
be nearly double the height of the world's tallest structure, the CN Tower in Canada.
"Solar towers are a good fit for power companies because they operate
24/7 and deliver maximum energy output during the hottest part of the
day just when everyone's air conditioners are on high,"
But unfortunately...
Despite the advantages of solar power towers, especially over the long
term, it's unlikely one will be built in the United States. The federal
government is pinning hopes on hydrogen as a new energy source, while
continuing to overexploit fossil fuels, said Collins. "Not many years
from now we'll have to choose between using oil for energy, plastics or
fertilizers," he said.
