When camping, electricity is scarce. This problem becomes especially painful if the adventures lasts more than a day and the Buzz is not around ☹. Phones, action cameras, lanterns and all the other gadgets need to be regularly plugged in.

Conclusion
Power banks are a viable solution but only for short-therm scenarios. How about solar, water or wind?
Solution
“Water to the rescue” is a portable water turbine that can charge all devices we need in our adventures. Flowing water is a great source of continuous electricity and also has the power to provide due to its density (compared to air). The device is simple to install and can be easily carried around.
Need addressed by this product
The system uses the DC motor as a dynamo in order to generate electricity.“Water to the rescue” does not use a battery pack;it charges devices directly from the engine. Users have the option to charge a portable power bank(already owned or bought separately)and charge devices from it at a later time
Further elaboration of the product
When submerged, the peripheral disc slides in the open position resulting in a pressure decrease and a velocity increase of the water flow passing through the device.
Further elaboration of the product
All yellow parts are 3D printed and the rest of the components will be bought separately and sold in the kit. Necessary parts to acquire (DC motor-8 €, rubber gasket, 8 screws, nut, electrical wires, USB socket, rope).
This is certainly out of the van thinking! Wouldn't this have to have a lot of third party components that would have to be put together? What parts are 3D printed? It seems to me this would have to go through extensive R and D and testing, to see if it's feasible. Nice renders though!
Hi man! Yes, there will be some components that need to be acquired and put together but nothing to fancy. All parts, except the DC motor can be bought from local hardware stores. There is also the option to sell the product as a kit and have the customer do the tinkering. All the best, Mihail
Hi Epure, all we can see is a fan, we need more details showing where you can store energy and how to charge devices...etc. Do you have time? Good luck :)
Hello Hicham and thank you for your comment. I hope the update clarifies the idea. Energy is stored only if the user has a portable power bank (in this scenario the electricity is stored in the battery and later used for charging devices). If the user doesn't have a power bank, devices will be charged directly from the engine (only if the system is in a constant water flow). All the best, Mihail
Hi Epure,
would definitely like to see more details on how power transmission and storage would work - and how much power can honestly be created with a method like this.
Could this be a working product soon?
Good luck!

Hello Markus! I updated the idea to clarify the solution. Unfortunately it's impossible for me to state at this point the amount of power the system can output. Some tests need to be made in order to define the best balanced product (refine the shape, blade angle and ideal motor). In terms of working or not... I'm sure it does. Why wouldn't it? All the best, Mihail
There is no doubt for me, this is excellent idea especially for those who camp next to river. Environmental friendly and free energy is must have today and if can be 3D printed even better. Only one thing is difficult here - electric motor must be in the water as well and it does not really like water :) that's why it must be isolated and this cannot be 3D printed and it costs. But great idea, really.
Hello M UT,
Thank you for your comment! You are right, motors and water… not good friends but I think that solutions can be found to keep the water away. It’s not clear to me why you think that using 3D printed parts implies the impossibility of sealing the motor chamber. In my opinion this can be achieved by using rubber gaskets when connecting parts and tightening the connection with screws. Ofcource, the rubber gasket itself will not be printed! You mean that 3D printed materials are not waterproof?
All the best, Mihail
Hi Epure, Problem is the fact that motor shaft ends in propeller which is in water. That means motor will be in the water as well. Gasket cannot solve sealing issue when you have rotating parts (motor shaft). What you need is mechanical drive pump. Are you familiar with that one. See this links if you have time and you will get my point. http://www.marchpump.com/about/magnetic-drive/ http://www.tmagpumps.com/how-it-works-magnetic-drive-pump Regards.
just to be clear, of course you intend to generate electricity from the water stream but in order to do this motor(generator) must be isolated from the water and that hopefully can be done by using magnetic drive where propeller shaft via magnet rotate motor (better say generator) and generate electricity. OK I am stopping here :) all the best
Hi Epure, Clever idea, sources of power are always handy. Good luck!
