You might want to start saving those stray hairs that end up in your hairbrush or shower drain, because they might be worth something. If fact, your mane could potentially power the electricity for your home. The discovery comes from a Nepalese student, who has invented a few way to make solar panels—using human hair instead of silicon as a conductor. As hair is an adequate conductor of electricity, it would significantly lower the price of solar panel production, and make construction of the devices accessible to everyone (well, except for bald people). So far, the experiment has succeeded in re-charging cell phones and batteries.
Would you be able to wrap your mind around using a blow-dryer or curling iron that was powered by exactly the thing its used for? Crazy! [InventorSpot.com]
