Thanks for the input
There is a plan, it goes something like this...
1- Build PMA
2- Source and prepare a motor
3- Test on propane
(If the digester is not operational at this point, continue using propane as fuel)
4- Connect to home supply with a grid-tie inverter.
Timescale: up to two years - i'm in no rush
If it exceeds my expectations, I will probably be 'feeding in', running most of the time.
If it meets my expectations, I don't intend to feed in, but to power the home intermittently - light/medium loads.
Provide power to the shed and lv lighting in the garden.
However it turns out, I will have enjoyed creating it, learned new things, and put into practice the things I haven't already forgotten...
I have the magnets, I confused myself trying to decide on which size copper to achieve enough volts and amps to run a good size house minus kitchen appliances.
I have been thinking about how best to ensure the rotor integrity at high rpm... i'm wondering if I might be able to get an offcut of >350mm dia. stainless steel pipe with a decent wall thickness, which would also become the mould outer edge...
Occasionally, there is a plus side to living in the 'steel city'
