> a unique hydrodynamic principle, the rolling fluid principle vortex dynamic
what?
> which can create a large amount of energy
The first law of thermodynamics may want to hear about that.
> an output of up to 10 kWh per day
so ... 417W.
> This is enough power to meet the requirements of 5 European families
[1] gives German usage for one household per day as 9.6kWh

- pjc50 10y agoI think it's been translated, too.
- ChuckMcM 10y agoFortunately the laws of Thermodynamics are safe, it it converting kinetic energy into electricity. It doesn't appear to be more efficient that existing hydropower solutions but it does seem to be applicable to a wider set of flowing water conditions (which is why, I'm sure, they keep talking about single family homes).
- tzs 10y agoIt's just slightly sloppy editing somewhere. It should be "rolling fluid principle, a vortex dynamic" or something like that. "Rolling fluid principle" is the name Sedláček gave the particular mechanism at play here, and it falls under vortex dynamics.
- Fremsley 10y agoHands up, I know zip about thermodynamic/fluid dynamics etc. My background is in mechanical engineering and editing. That article doesn't pretend to be a technical masterpiece, but instead is 'WEB' written, and serves solely as an introduction to a relatively unknown design and concept. Which, consequently, is available to buy should anyone wish to pull it to bits and have a look at the internals, which is something I wouldn't mind doing!
