Future Energy Technology: Glow-in-the-Dark Trees

San Francisco entrepreneur Antony Evans had a vision: "Can we use glowing trees to replace street lamps?" Evans and his colleagues, biologist Omri Amirav-Drory and Kyle Taylor, want to create plants that will glow naturally. People create transgenic organisms by adding genes from another species into the DNA of plants or animals in order to satisfy a variety of human needs.
