Your mobile phone may have a long battery life. That won’t last forever. You could always use a solar charger to power your gadget. That’s not the only way though. Hydrobee happens to be a USB charger that generates energy from flowing water (rivers, streams, faucets). It is a tiny hydropower turbine in a can with rechargeable batteries. As long as you have water flowing at walking speed, you will be able to generate power for your devices.
The Hydrobee can be used to charge phones, tablets, water purifiers, LED lights, and more. Best of all, it does not rely on the sun or wind to charge your gadgets. The developer is seeking funding for the project on Kickstarter.
