Tiny Turbine Generator Test

This is an ultra small turbine that i made, in order to make it work as a tiny generator coupled to a DC motor (180 type), i had laying around. Basically it's a Pelton type turbine, which is really easy to make.
Of course, due to the lack of equipment, i went with a simpler design. The process i follow to produce the turbine blades can be seen in the first photos of the video.
It is a radial flow turbine, with a simple converging nozzle. The main body was made using the sandwich method (layer upon layer etc.), using melted solder to bind the layers. The materials are not exotic in any way (maybe except from the hybrid bearings, which is not anything special)
As a generator using this electric motor it is capable of producing a little more than 2.5W of electrical energy (14.6V x 0.175A = 2.55W). Of course i's not very practical and not very efficient
either, but very fun to play with. I would like to make the rotor with embedded permanent magnets and of course a stator, but this just to complicated, so a brushless motor instead of the current motor would be great..
