I hope this is the right forum.
What would I be up against if I were to build my own personal hydropower system in New Hampshire?

Substantial technical challenges, if you had a property with a good-running stream and a major drop on it.
State and Federal regulations if you were talking about building a dam.

The article states that it requires a stream four feet deep, moving at 7.5fps. That's not something you're likely to have on your property. |

That is something I'd be looking for. If I could I'd collect land.

Also...
I have been wondering if it is doable to get power from the magnetic field, or any magnetic field. I don't think it would power the house but it might help. Any thoughts?
It looks like southern New Hampshire has a bit of geothermal activity. Is it practical to tap it?
A network of solar, wind, and maybe hydro and some blades on a woodstove should do it, but I wonder if I could tap into something more consistent.

trial, error and testing.
all you need is land and neighbors who stay out of your business.

You need a moving magnetic field to induce a current in a wire. The earth's magnetic field is akin to a magnet sitting next to a wire - nothing happens. You need to move either the magnet or the wire, so the field cuts through the wire in order to generate power. You can't generate meaningful power even if you start waving a wire around outside, because the flux density of the earth's field is minuscule. It's enough to make a tiny, balanced compass needle move, but the magnets in a generator are many, many thousands of times stronger. It looks like southern New Hampshire has a bit of geothermal activity. Is it practical to tap it? Not without drilling a very deep well. A network of solar, wind, and maybe hydro and some blades on a woodstove should do it, but I wonder if I could tap into something more consistent. Wood is more practical. Wood-fired generators are not inexpensive, but they are not ridiculous, either. And wood is so common that it literally grows on trees  - so the cost per kWh is pretty darn small. |

I'd eventually like to experiment with Telluric generators, but I should read up on them to make sure that isn't a dead end.
