The Hydrobee is the new thing in hydropower. Over 100 million people live without reliable electricity, along the shores of streams and rivers and lakes and oceans. Millions of them have phones and must pay local vendors to charge them. Where the water is moving fast, or where they sail in canoes, now they can get free clean renewable energy for USB power using this little turbine. The inventor is Kickstarting it and already has over 100 backers in a few days. Give them a thumbs up!
