Steve, here are some specs: the dish is about 75 feet in diameter, and weighs about 71 tons. It has about 300-350 square meters of reflective area. The general rule-of-thumb for power radiated by the sun is 1 KW per square meter, but the mirrors are never perfect.
Our job is to disassemble the dish, then reassemble it at a new location, where it will be used to test Sterling hot air engines.
G'day Mick. We had to coat the mirrors with a secret "mud" recipe before anyone could work above the mirrors without getting fried.
