115-foot 'tulip' harnesses sun's rays to power villages (7 pics + video)
An interesting new entry in the solar power market is blooming in a desert in Southern Spain. 50 mirrors track the sun and reflect its light into a 115-foot high tulip-shaped tower; the concentrated rays cause the air in the bulb to heat up to over 1800 degrees Fahrenheit. The super heated air is then forced into a combustion chamber where it expands, powering a turbine generator and creating electricity.
