Researchers have developed a power-harvesting device able to convert stray microwave energy into direct current voltage large enought to recharge a small electronic device.

Created by a team at Duke University, the device is inexpensive to make and operates on principle similar to solar panels. Made of a series of five fiberglass and copper energy conductors wired to a circuit board, the device is able to convert microwaves (such as those from a WiFi hub) into 7.3V of electrical energy. This amount is comparable to that achieved in solar cells.

The team believes the metametal could be applied to the ceiling of a room to recover a WiFi signal or to improve the energy efficiency of appliances by recovering the power currently lost during use. Additional modifications could see the material built into a cell phone, allowing the phone to recharge wirelessly and potentially harvest power from a nearby cell phone tower.

Analyze that all energy in our environmental is use from solar power. What happen the day solar emission's decrease and what energy will be use to balance that one.
Science must be focused in an alternative energy that work without solar backup. We need to go farther in our investigations to create environmental energy outside our solar power. Should be a great investigation asset for the near future.
