Wonderful idea for charging our instruments of daily use. Hope it wins due to its simplicity - Good luck!

It's very great, very useful and green clean.

Great idea, would like to get one for myself.

Please tell me the gearing is different when turned by water. ie the dynamo turned many times by one turn of the blades when in water.

Great idea, very good luck !

Hey send me some information as well please. I am interested in purchasing one :) Cheers

OK, buena idea. Please send me mor info because very interesting best regards Franco from Italy soco@soco.it

great idea and nice design !

I'm not sure about this particular design, not knowing much about engineering. The concept is very exciting and could have many grand offshoots! Why can't we be more flexible with what kind of energy we have at a given moment? Water, Wind and (why not Solar too) all in one device, made as compact as possible! Yay! Keep groovin' with this idea!

This is just a nicely shaped Savonius type windturbine. This has a very poor aerodynamic efficieny.

thats a super idea! i liked it a lot!

From an engineering standpoint having the same turbine blades for dealing with air and water (700 times denser than air) does not make much sense, also it is way to small to generate any power in air unless you are in a windstorm. The folded size doe

I am into this idea, never considered wind and water from one device. hope it could be waterproof. foldable for mobile power is great. when you get one built let me know, would love to test it with ecopioneer program. good luck!!
