Using technology at a nanoscopic scale, Dave Carroll and his research team aim to provide solutions to some of the world’s most pressing problems: the need for affordable “green” or alternative energy sources and reliable treatments for deadly cancers.

In the green technology field, Carroll’s research has yielded a new class of flexible, affordable solar cells; several replacements for energy-burning incandescent and dangerous compact fluorescent light bulbs; and a fabric that can power a cell phone using the caller’s body heat. In the medical field, Carroll has developed nanotechnology that heats tumors until they die. Another nano-scale treatment helps surgeons regulate pressure in arms and legs during reconstructive surgery – greatly reducing the risk of amputation. He holds 12 patents and has been quoted in Discover magazine, the Raleigh News & Observer and WFDD.

David Carroll on:

the expense of green technology

“It comes at a pretty high price to be green. … We’ve known how to build the ‘smart house,’ it’s just been too expensive.”

making an efficient solar cell …

“On a rooftop, you have a lot of visible sunlight and heat from the infrared radiation. The solar-cell industry has for the most part ignored the heat.”

creating the best light bulb alternative …

“If you have a lighting source that does not create heat as a byproduct and can illuminate a space as well as or better than any other solution, think about how much it can lower costs – and environmental impact – in every office building.”
