Researchers work toward harnessing ocean energy to power devices

Tsunamis, hurricanes, and maritime weather are monitored using sensors and other devices on platforms in the ocean to help keep coastal communities safe—until the batteries on these platforms run out of juice. Without power, ...

How wireless recharging works – and doesn't, yet

Though the days of hardwired wall-mounted phones are ending and wireless internet connections are common at home and on the go, people are still dependent on cords to charge their mobile devices. My research, and that of ...

With new solar modules, greenhouses run on their own energy

Plants use light waves from only a portion of the spectrum for photosynthesis—the remainder can be recovered and used to generate solar power. That's the idea behind the solar modules developed by EPFL startup Voltiris. ...

Wireless system can power devices inside the body

MIT researchers, working with scientists from Brigham and Women's Hospital, have developed a new way to power and communicate with devices implanted deep within the human body. Such devices could be used to deliver drugs, ...

Detonation-based device for novel propulsion applications

Combustors that drive propulsion systems are often volumetric in nature, typically in the form of cylinders, and convert chemical to thermal and mechanical energy through oxidation of fuels. This deflagrating combustion approach ...
