Sick of your phone running out of battery? Now you can use a mini water turbine to charge it up. With the invention already a success in India, the German engineer behind it now has his sights set on the African market.

Me thinks a common 400 watt solar panel would be a lot cheaper and easier to use but it probably does have some applications like on cloudy days. I'd be concerned a sizable branch or piece of wood would take it all out! Price needs to come down!

GREAT IDEA - CAN THE OUTPUT BE STEPPED UP TO 1000W AT 250V WILL GIVE YOU 4 AMPS WHICH IS THEN I BELIEVE IT WILL BE VERY VIABLE FOR HOUSING AND REMOTE AREA COMMUNITIES.

If this can generate and store electricity future vehicles can use this technology in the wheels. Add air turbine like on the vehicle roof to maximise electricity generation.

If I were going camping for a couple of days, I'd find that a spare battery pack for my mobile would be cheaper and less bulky. If I were powering a small community, I'd want something bigger and more powerful. You get steady wind in more places than you get flowing water. If I were doing an energy audit, I'd be wondering how long this device would have to be running before it generated more power in total than it took to manufacture it. It has "gimmick" written all over it.

glue it some centimeters under a pièce of styro with fin to ensure a constant deep and avoid twisting the cable.

Great concept - as for Cost-------- QUALITY COSTS MONEY only issue i can see is that eventually water ingress could be an issue - a unit that could produce an output of 1 Kw at 12 volts would be perfect for a remote more permanent type install for use with solar panels and wind turbines a DC output is ideal as there is no synchronizing issues as long as Voltages are the same thru batteries which will act as capacitors taking up the differentials.

No need for an Brook, Stream, Or a River, simply tow it behind your boat while on the lake. Here in Houston, we have many open concrete waterways, what a great idea for power outages, after a flood or hurricane.

Fascinating idea, but far too expensive for the people whom it's supposed to help. A rig like this, needs to cost about $39.00 US. For me, it would be a novelty, not something I would rely on everyday. For day to day use, I would use a photovoltaic panel. Especially for the price. Not so much that this is expensive, but because panels these days are so affordable, and can be used anywhere.

They have to make new design for homesteaders and off grid users, but the one in this video is for hikers and campers. I like ask if could create another one for ppl in general who want to test it out in their gutters and they probably could test it out do field and lab test study, So it called "Blue Freedom Portable" and you get from here : blue-freedom.net/

Great idea, off to a good start, lots of blah blah below about solars better, what ever, no one said there can only be one way to create power, and if you do live near, or going to be near, running water why not, the price seems to be an issue for some, if the quality of construction is top notch and the device will last for many years of use then they can't be produced and sold at the dollar store.

Correct me if I’m wrong but, isn’t it just a motor shaft connected to a wire connected to a propeller? Of course their is the battery and circuit board but those don’t cost much at all to make. That thing is worth probably $120-$180 at most

😫 God Damn do you people in the comments understand how development occurs? Do you actually think solar and wind when first developed they cost the same they do now? Solar by itself is never going to be the answer it will require the combination of solar, wind, and hydro amongst other green tech to break our dependency on fossil fuels and atomic.

Get it down to $20-50 and you have yourself a deal! But like all new things like this, it will be a bit before we see anything like that. I've forgotten at least a dozen neat inventions that were super promising and made it to this stage, and haven't heard anything about them in years. But if you're gonna be charging $300+ per unit, you can get a 100w solar unit for that price

All things in nature are layered. So why wouldn't a layered approach work for our energy needs? Different environments require different solutions. Price always goes down in time and with competition. Western nations have an insatiable appetite for energy and will stop at nothing to aquire it, so I imagine it would be difficult for these folks to understand the simple energy needs of these villagers.
