UCLA is a new device that creates electricity from falling snow. The first one is a sheet of plastic.

"Static electricity occurring from the interaction "One of the material that captured electrons," said Kaner, who is also a distinguished professor of chemistry and biochemistry, and a member of the California NanoSystems Institute at UCLA.

Snow is positively charged and gives up electrons. Silicone — a synthetic rubber-like material that is made of silicon atoms and oxygen atoms, is negatively charged.

"While snow likes to give up electrons," he said. added.

About 30 percent of the Earth's surface is covered by snow each winter, during which time solar panels often fail to operate, El-Kady noted. The amount of sunlight that reaches the solar array is the power output and rendering them less effective.

The device can be used for monitoring purposes. , walking or jumping, Kaner said. It is also a good thing to do with it.

It could usher in a new generation of cross-country skiing.

It can also send signals, indicating whether a person is moving.

The research team used 3-D printing to design the device, which is a layer of silicone and an electrode to capture the charge. The team believes the device could be produced at low cost, "Kaner said. Silicone is widely used in the industry, as well as in the field of electrical power supply.
