Ah, I actually meant Rodney - I suggested it to him in his previous topic: > [@Homemade generator](https://forum.core-electronics.com.au/t/homemade-generator/9265/2): > > Hi Rodney, Sounds like an interesting project! There’s an awful lot of energy involved in something that fast and powerful so it’d probably be best to start with something small scale so that you understand the principles before scaling up to something larger. I’ll always remember the photo in my thermodynamics textbook of the carnage in a room after a centrifuge let go - it looked like a hand grenade had gone off (and the energy released was about the same!). Here’s a spinny thing letting go… Yeah, definitely not a high power thing, much more useful as an educational tool, but if you’ve ever got a situation where there’s a regular supply of water (eg. in agriculture or gardening) and there’s a little bit of energy to spare from the flow it’d be handy for running a data logger of some kind.
