Musical GPS lets you steer your bike without looking at a screen
It's hard enough to look at your GPS and at the road while you're driving, but on a bike that split second of inattention could easily lead to injury. So Dutch researchers, who know from biking, have developed a music-based navigation system called "Oh Music, Where Art Thou?" It's a smartphone app that lets you navigate by following a strain of music through the streets. If the sound seems to come from the right, you go right; if it comes from the left, you go left. (Hopefully there's a needle-scratch feature for missing your turn.)

Panda poop could revolutionize biofuels
One down side of biofuels like ethanol is that they rely on easily processed crops that are also staple foods. The more farm space is given over to raising corn, soybeans, and sugar for fuels, the less is available for raising those crops to feed humans. Luckily, scientists have just discovered microbes that could help turn waste plant matter like corn stalks and wood chips into fuel. All they needed was a little bit of panda poo.

How old is your phone? I bet mine is older
Planned obsolescence is morphing into desired obsolescence: Customers want gadgets to wear out so they'll have a good excuse to buy a new one. But some of us cheapskates aren't playing along.

Toyota concept bike has psychic gear shift
Parlee Cycles and tech company Deeplocal are working together on a bike inspired by the Toyota Prius. It's a reasonably slick-looking machine, but the really weird and bizarre part is the "neuron shifting." The bike uses a gaming neuroheadset, which detects the brain's electrical activity like an EEG, to let riders shift between gears using only their minds.

Could you use the internet to heat your house?
Servers generate so much heat that they have to be kept in super-cooled rooms, lest the entire Cloud collapse. People's houses need heat, at least in the winter months. Two great tastes that go great together?

Paper antennas pull electricity from the air
The air is full of energy -- not in a woo-woo crystal-gazing way, but in a scientific electromagnetic-radiation-from-TV-stations-and-phone-networks kind of way. That ambient energy is just being wasted. But a team from Georgia Tech is developing inkjet-printed paper antennas that could generate enough energy to power a small gadget, right out of thin air.

In the future, cleaning robots will sniff out air pollution
Researchers at the Public Laboratory for Open Technology and Science have kitted out a Roomba -- you know, one of those robotic vacuum cleaners that cats ride around on and act out Citizen Kane -- to evaluate air quality. Lights on the Roomba indicate the presence of evaporated alcohol, and a long-exposure photo, above, can show which parts of a room are clean and which are fumey. Blue lights in the above photo mean that the robot detected polluted air.

New solar cells can be printed on paper or fabric
Finally, your dream of solar pants (that don't look douchey) can come true! MIT researchers have devised solar panels that can be printed directly onto fabric, plastic, or paper, as easily as printing from an inkjet. The result is a flexible, malleable solar panel with enough juice to power ... well, okay, barely any juice at all right now. But it's still in the early stages of development! Besides, once you pair your solar pants with a solar shirt, tie, bag, fedora, and shoes, it'll start to add up, and you will also look very snappy.
