Pee-powered socks generate emergency electricity
A team of researchers from University of the West of England in Bristol, UK want you to pee in your socks. You know, in case of an emergency. They've developed a novel power system that leverages your own liquid waste to generate electricity in an emergency. It's essentially the same process as the still suits from Dune, just with electricity instead of water filtration.
Mitsumi exhibits micro-vibration power generator and batteryless RF switch (video)
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.
Snail turned into living battery, should have taken the blue pill
You know how those mad scientists at DARPA are obsessed with generating power from insects? A team from Clarkson University, New York and Ben-Gurion University, Israel has gone one better by turning a Snail into a cybernetic power generator. A pair of Buckypaper electrodes were charged by the electro-chemical reactions in the slow-moving invertebrates "hemolymph," its equivalent to blood. Its hoped the Snails will provide a sustainable way to power listening devices for the Department of Homeland Security, so if you suddenly find your crawlspace full of gastropods, be careful what you say.

Times Square New Year's Eve ball drop brought to you by... some furiously pedaling tourists
Hey, if you're in New York City and bored on New Year's Eve, well, maybe you feel like working? Duracell's set up its Smart Power Lab in the heart of Manhattan, along with several Power Rovers, which are stationery bikes that generate renewable energy when pedaled. You see where this is going, right? That energy is being stored up and harnessed by Duracell to power the ball we watch drop every year, which boasts about 9,500 LEDs. Fun times, if you're not averse to the freezing cold, the screaming crowds, the garbage, and the awful music. Or you could always do what we do, and stay home in your jammies watching Twin Peaks -- but it's really up to you. Either way, we're glad to see the ball is no longer powered by Dick Clark's rage. There's one more shot after the break.
Power generating backpack is a gift from the gadget gods, Uncle Sam
Without a doubt, the military is home to some of the best gadgets. Fortunately for us, the non-lethal stuff often makes it into the hands of consumers after companies finish milking the government of its R&D budget. Case in point: this electricity-generating backup. Designed for the military, the kinetic energy pack is suspended on a rail that generates electricity as you walk. The power generated will charge a standard US Marine-issue lithium ion battery pack or can be directly routed to whatever device you want to charge. The obvious benefit would be limitless power in the field freeing troops from carrying extra batteries on long missions. A power meter on the shoulder strap lets you monitor performance while a three-stage resistance device lets you regulate the power output. A braking mechanism lets you lock down the pack when you want to keep the pack steady. Otherwise, it looks like it'll generate about 8 watts of power while walking or 44 watts of power when running. Do want. See it in action after the break. [Via besportier]
Glass leaves sweat to generate electricity, get nervous in public situations
Researchers at the University of California, Berkeley, the University of Michigan and MIT have created glass "leaves" with networks of veiny channels filled with water. The smallest channels extend all the way to the edges of the leaf, where open ends allow water to evaporate, which draws water along the central stem of the leaf -- at a rate of about 1.5 centimeters per second. The glass leaves have been wired for electricity by adding metal plates to the walls of the central stems and connecting them to a circuit. Researchers then charge the plates and the water inside the stems creates two conducting layers separated by an insulating layer, which acts as a capacitor. The waterflow is then periodically interrupted with air bubbles, and every time a bubble passes through the plates a small electrical current is generated -- about 2 - 5 microvolts per bubble. The team thinks that on a large scale, artificial trees could be use to generate large amounts of energy entirely through evaporation.
Piezoelectrics installed in Tokyo railway station floors generate power, wastes it
The East Japan Railway Company has been running tests on a "power-generating floor" since the beginning of January 2007, but they've just installed the system for public testing in several areas of the Tokyo station. Using piezoelectrics similar to that we've seen before in a UK discotheque, the Japanese company says the power-generating capacity of the flooring has increased ten-fold over its initial results, and they now expect to generate 1,400kW/sec per day. With that, they plan to power the display pictured above, which shows the power generatd by the floor. Sound a little redundant? Fear not: they plan on using the juice to operate automatic ticket gates in the future. [Via Inhabitat]
