Business 2.0 reports about what could possibly be one of the biggest breakthroughs of the year: an over-the-air charger for low-power devices (cell phones, MP3 players, automotive parts, temperature sensors, hearing aids, and medical implants)The system works through a power transmitter - recevier module (see illustration on the right). The receiver that "catches" the power from all the bouncing radio signals and converts it to DC power is actually the magic piece of the system. And it just costs 5$ to make.
Powercast, the company behind the product, has already partnered with many device manufacturers to produce the "receiver" for these devices to make them compatible with the company's over the air charging products.
so basically it takes a few more bucks to make a radiowave-powered taser. w00t!
ReplyDeleteit really depends on the wattage of the taser, because for now, it can only power low-wattage devices (take note: no support for laptops yet) . :)
ReplyDeleteAnd the technology as it is now will only allow a distance of around 3 meters from the power charger/transmitter to the device. So, you would still have to have a power source nearby. A motolite backpack perhaps?
hehe.
tech is rapid now. in a few years the radiowave taser can and WILL be possible.
ReplyDeleteand if the taser's voltage is not high enough to suit you, you could always chuck the motolite backpack at your enemy.
how about: a radiowave-powered radio! infinite energy for the win!
