Raymond Saluccio is the CEO of New Jersey based EarthSure, a company that recently announced its own plan to route light, be it from the sun or incandescent light bulbs, using fiber optic cables connected to underground solar panels.

Known as SubSolar, the plan could generate solar power 24 hours a day, seven days a week in hospitals or office buildings where the lights are always on.

"We don't even have to put the fiber optics on a roof," said Saluccio "We can put our fiber optics cables in the lawn, on a tree, even indoors."

Instead of generating power on the surface of the fiber optic cable, the light would travel to submarine-shaped capsules buried several feet underground.

Homes could be powered by six-foot-long systems, while businesses would need a pod up to 20 feet long and 10 feet in diameter.

"Putting the panels underground we can make them out of cheaper materials because they don't have to stand up to heat, cold, rain, hail, or sleet," said Saluccio.

Until EarthSure can raise more funds to develop a prototype device or Wang creates a start up company to produce and market, concealed solar panels will remain out of reach for most consumers.
