I saw some stuff from Abound here in Colorado. The vacuum chamber where glass sheets became solar panels was 100 feet long, had multiple huge, fast vacuum pumps and ran at a high enough temperature(900C) to lift the middle off the ground in operation from thermal stress.
The 2 x 4 foot panels produced 500 watts. Will one of these produce enough electricity to recover the juice used to make it?
Abound. Another tax payer funded failure run by a big money democRat donor.
