Apparatus using a balloon supported reflective surface for reflecting light from the sun

摘要

The invention provides a family of apparatus using a balloon supported reflective surface for reflecting light from the Sun. A basic embodiment of such an apparatus is a light weight, low cost heliostat using a balloon supported reflective surface. Another embodiment is a solar power concentration apparatus using multiple heliostats with balloon supported reflective surfaces. Yet another embodiment is a solar electric power apparatus, also using multiple heliostats with balloon supported reflective surfaces. Variant embodiments of these apparatus can be sited on land or water surfaces or in the air or in space.
