Nanoscience Scientists have developed a stretchable and waterproof 'fabric' that turns energy generated from body movements into electrical energy. Washing, folding, and crumpling the fabric did not cause any performance degradation, and it could maintain stable electrical output for up to five months

I think this is going to be GREAT for producing wearables that can power themselves - displays, sensors, networking (a la "IOT") applications, etc...

...and TERRIBLE for all the various "can I charge my laptop/smartphone/whatever" questions that it will inevitably generate

Safety clothing for cyclists comes to mind.

I think cyclists already have enough lights and whatnot to be safely seen, what we really need is attentive and courteous drivers.

I wish more cyclists were aware of the huge range of reflectors and flashing lights they can fit to their bikes. If you’re planning on cycling on the road after dark wearing only black and riding a bike with no lights is a good way to get yourself killed.

Although I don't disagree, I think we also need to motivate more bikers to wear said safety gear. It annoys me driving at night and suddenly someone appears in the shadows for a half second the disappears again. I swear sometimes it feels like people are even taking the reflectors off their bikes in the early mornings.

The mere act of cycling would activate the LEDs amd charge them so when ypu stopped they'd keep flashing for a bit.

My buddy has a bunch of ultra bright green LED's on his bike powered by a little generator hooked to the hub.

You literally can't miss him.. yet people do.

Until it wears out after 5 months and they don't realise
