This dream has lead many people to do what, in retrospect, seems obvious, and look upward toward nature's "fusion reactor", the sun. However, while sunlight is clean and inexhaustible (for a few billion years anyway!), it is also dilute and intermittent. These problems led Peter Glaser of the Arthur D.
