Power from Human Gait

Engineers have developed energy-harvesting technology called "reverse electrowetting" to capture the natural energy of human motion and use that power to charge and run personal electronic devices.

Capturing Ambient Energy

Engineers have developed technology to collect energy from ambient electromagnetic broadcasts such as radio and television, wireless communication networks and satellite transmissions and use that energy to power small electronic devices.

First "Artificial Leaf"

Scientists have announced the development of the first practical "artificial leaf," a card-sized silicon solar cell that converts sunlight and water into energy through a process that mimics the natural photosynthesis of green plants.

"Artificial Leaf" Solar Devices

Researchers have developed water-gel-based solar devices ("artificial leaves") that mimick natural processes using plant chlorophyll, carbon nanotubes or graphite to generate electricity that is less expensive and more environmentally friendly than current silicon-based solar cell technologies.

Glucose Biofuel Cell

An implantable biofuel cell has been successfully test in a rat, drawing its power supply from the natural glucose and oxygen available in the body and producing a significant amount of electrical energy while the subject suffers no ill effects.
