About me
I hail from an education nurtured city called "Pune". Located on the western part of India, Pune is around 180 Km (112 miles) away from Mumbai (formerly Bombay).
I completed my Bachelors degree in Electronics and Telecommunications Engineering under University of Pune. My further education took place 13000 Km away from India at Concordia University, Montreal, CANADA. My Masters degree consist of 5 courses (20 credits) and research thesis work (29 credits). I proposed different power control algorithms for WCDMA cellular system.

PowerBeam co-founders David Graham and Xiaobing Luo showed me how they could power up a little toy with a spinning fan without using either batteries or a wired power source. They can do so with an invention that seems suspiciously simple.
They pointed a laser beam at a solar cell. The solar cell collects the light energy from the laser and converts it into electricity. Light in, electricity out.
Then the electricity travels from the solar cell into the device. They call it an "optical power beam."
It's the same principle that powers your pocket calculator with a solar cell. But in this case, PowerBeam gets a lot more electrical power from a laser as far away as 65 feet.
In a patent application, PowerBeam says it can produce much more electrical power than other methods because it has tamed a dangerous laser. It uses a powerful laser of the sort that could cut through your hand, but it has integrated a safety system, allowing it to channel a lot of energy into the solar cell.
