The Hydrobee™ is the new alternative in off-grid personal power for a billion people. It is a tiny hydropower turbine in a can with rechargeable batteries, clever electronics, and a USB 2.0 port. Water flowing through or around the turbine charges the batteries. Then you pick it up and have a can full of electric “juice” to go. As long as you have a stream or river flowing at walking speed, or a household water faucet and standard flow, the Hydrobee™ is a renewable USB power source for you. Says their Kickstarter campaign.
