Rod: camping and hiking give you the chance to get away, but if you still need to "plug in," there' a gadget for that.
Carrie: two teen- entrepreneurs are designing portable hydro- electric generators through "rev ithaca" -- a business incubator partnered with cornell university.
Newschannel nine's farah jadran shows us how it all works.
Hunter hartshorne: "it's mostly three-d printed parts.
There's actually one waterproof seal here so it allows us to.and inside you have the usb port so you can charge."
Farah: they just graduated from ithaca high school and they're getting ready to start a business geared toward their fellow hikers and campers.
They're testing designs inside cornell's hydraulics lab with "rev ithaca" to get hillside hydro off the ground - an idea they stumbled upon while building a cabin.
Jasper white: "while we were up there, we were doing all this manual labor without any electricity and we thought, man, it would be great if we had power tools or something."
Hunter hartshorne: "we thought it would be a cool idea to bring electricity to that cabin, so it started as a little bit larger small-scale hydro- electric project."
Farah jadran: you don't need quite this much water power, but if you look down the stream, there's plenty of renewable energy right at your fingertips where you can plug in this lightweight, portable device.
Farah the generator weighs less than a pound, so it's easy to pack.
A tether helps it ride the stream as propellers gain energy with every turn.
An average run for about 8 hours in a steady stream, like this one at the cascadilla creek in ithaca, holds enough power to charge your cell phone to full battery three times.
Brian bauer: "what do you estimate the speed is here?"
Hunter hartshorne: i think the speed is around 1.2, 1.3 meters per second."
Farah they say the collaboration with rev resident entrepreneurs like brian bauer is helping "stream- line" the future for hillside hydro.
