There is a new hotel in Vegas whose curved, reflective glass facade is focusing sunlight into a “death ray” that beams down onto a certain area on the hotel’s pool deck and giving sunbathers serious burns. Link to that story here. Well if you thought that was cool (no pun intended) watch the video below where scientists have focused two square meters of sunlight in such a way that it can melt ROCK! Explain to me why we are not using this simple, clean technology to fire steam turbines for emissions-free electricity?
