Mitsumi exhibits micro-vibration power generator and batteryless RF switch (video)

Mitsumi

This picture from Mitsumi's CEATEC booth may not seem to say much, but it's certainly showing the future. The silver cylinder at the top is actually a small power generating device that converts micro-vibrations into usable energy, so stick one of these on, say, a ventilation duct and you should just about get enough juice to power a calculator or even an LED. In fact, Mitsumi says these can be integrated into the RF sensor network of large air conditioning facilities, as an RF transmitter can run on very little power these days -- even less than a calculator. Alas, a company rep said this product won't be available until 2014.

Speaking of RF, Mitsumi does have something even more awesome that will be launched sooner. You see that black stick on the left? Embedded inside it is a batteryless RF switch, and the way it works is that upon the release of the spring mechanism inside, a tiny bit of power is generated for the 2.4GHz RF transmission (ZigBee compatible), and whatever device is connected to the RF control outlet on the other end will receive the on or off signal. So yes, you basically get a switch that requires no wiring nor power (except for the receiving end)! Expect this to hit the shelves in March 2013. For now, we have a hands-on video after the break.

Researchers use virus’s rogue traits to create electricity from motion

Viruses are the swarming bullies of biology, but it turns out their alarming self-replication could one day power your iPod. We've seen them in batteries before, but researchers at Berkeley Labs have now coated electrodes with modified M13 bacteriophage, a harmless bacteria-eating virus, to create the first ever organic piezoelectric material -- which can convert force to electricity. The team explained that such a substance would be non-toxic, organize naturally into thin layers and self-regenerate, giving it a possible advantage over chemical options. In theory, by attaching a thin film of it to your shoes, power could be generated when walking, lending volts to the myriad electronics we pack around nowadays. To see a finger-powered video demo of our frequent-enemies making themselves useful for a change, stroll on past the break.

Insert Coin: The PowerPot portable electric generator (video)

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

Assuming you're not getting through the day with a bounty of fuel cell-powered gadgets, you've probably been in a situation where you needed power and it was nowhere to be found. The PowerPot isn't the most practical solution for every scenario, but it's likely to come in handy at least once. The power-generating pot uses thermoelectric modules to convert temperature differences into a 5-, 10- or 15-watt regulated power stream, sufficient for juicing up USB devices like smartphones, GPS devices and LED lamps. The most traditional method for creating this temperature difference is to put a pot of cold water over an open flame, but the device is adaptable to other configurations -- a pot of snow on a thermal spring, for example. Assuming you've taken the fire approach, you can also use the pot to boil water or cook food as you charge your gadgets.

The inventor has created a functional prototype that features fire-proof components and looks quite polished, but now the team is turning to Kickstarter to advance the project to production. Your pledge could net you any of a variety of PowerPots, ranging from a 5-watt portable V flavor for $125 to the 15-watt XV for $500. You can also pre-order a 10-watt PowerPot X for $199. If you're feeling generous, there's also an option to donate a PowerPot to folks in developing nations who may not have the cash to spare, but are in need of a cost-effective solution for power generation. Jump past the break to see the PowerPot V in action, and hit up the source link to scroll through the available configs before making your pledge.
