Turbine flow design has changed little since their invention in the eighteenth and nineteenth centuries due to the simplicity and power of these devices to extract energy from the movement of a ...

[Tom Stanton] has been messing around with compressed air power for a few years now, and most of his work focused on piston engines. He likes using 2-liter soda bottles as lightweight tanks but their ...

I have a soft spot for Pelton wheels – those power generating turbines that need an awful lot of pressure and very little flow, and can score high 90s of percent in efficiency terms. On a visit to ...

We all know the story arc that so many projects take: Build. Fail. Improve. Fail. Repair. Improve. Fail. Rebuild. Success… Tweak! [Kris Harbour] is no stranger to the process, as his impressive ...

After nearly a year the new power system and upgrades to the 30-foot Pelton water wheel that was installed in 1898 and was in continuous use for over 40 years at the North Star Powerhouse Museum in ...

Turbine makers get immense benefits from stress-relieving by induction annealing with eldec MF generators: the technique ensures highly efficient annealing on Pelton turbines employed in hydroelectric ...
