Solar Power for Vampires: MIT Team Invents 24-Hour Solar System

Solar Power for Vampires: MIT Team Invents 24-Hour Solar System

The MIT team resolved the cost problem with a ground-mounted tank instead of a tower. The low-rise system eliminates a significant amount of plumbing and related equipment, and it would be less expensive to install and maintain over the long run. Rather than positioning mirrors to focus sunlight upwards to a tower, the mirrors would be positioned on a hillside above the tank, and focus sunlight downwards to a narrow opening at the top of the tank, achieving temperatures of more than 500 degrees Celsius. The tank would double as storage by use of a floating barrier that adjusts itself during daylight hours to keep the heated salt separate from cold salt.
