Who's using what to power things?
After ideas for charging the likes of a car battery for powering small items like lights etc in a hut/cabin.
Or would I be better off going with a decent solar panel?

Bro sound heavy and bulky to carry around

Private hut/off grid system.
Permanent solution for a weekend small holiday house.
Stream near by with constant flow but I think trying to filter it might be a pain and solar might be easier.
Main use will be to power some LED lights and charge phone and camera.
gentil annie motors or rewired smartdrives are quite common.
Have a look at this

Nice. Pretty sweet setup.
Will have to look into cost after plumbing water to the hut, as an all incorporated setup would probably work quite well.
I’m having solar priced up again this week.
Interesting.

Based in Taranaki somewhere. Off the shelf options seem a bit pricey, but I guess you're trading $ instead of the time spent to do all the research yoursefl, sourcing parts, building it etc.

geebiz theres some cost involved there.Quote:

Not needing to power a full blown house thankfully.
Think 100W solar panel and controller probably easiest and laziest route.
I've got the guts of a smart drive if you want to have a crack at making a hydro setup. But yeah, solar probably simpler for keeping a rarely used battery bank charged.Quote:

cheers mate I'll keep it in mind.
$200 can get me a 100w panel and controller so thinking that's going to be most cost efficient by the time you add piping etc into the equation
Thought about getting something like this at my Bach, running it connected to the town supply and feeding the port back into the grid to drop my power account! Waters not metered:thumbsup:Quote:

I did a course years ago with those guys, very nice and interesting. If you have a stream continuously running nearby, that is really the best solution.
Yeah, a mate did a summer internship with them back when they were EcoInnovation. Some interesting stories. Like the time they plumbed a school in Stratford or Inglewood for solar hot water. They found a big hot water cylinder in a locked cupboard that had an inlet and no outlet. Thermostat cranked right up and had been spitting hot water onto the roof endlessly since installation decades prior.Quote:

I had a mate that rigged up a washing machine as a Pelton generator in a creek. The water flo turned the motor generating about 1000 watts or so. It was enough to power a small heater continuously through winter without having to hook it into the "grid"....Unfortunately he passed away. But I know it works, and he was in that industry.
Our school did something similar with the school pool back in the 80s. They thought asphalt gets hot in the sun. It can heat the water for the pool, so they plumbed the water from the pump through a large series of pipes under the asphalt and back into the pool. Alll seemed very simple and logical. One of those "why didn't we do this years ago???"moments. Well.....the water passed through and cycled fine. Problem is simple. Black asphalt gets hot because it absorbs energy / heat. Issues arise as it also absorbed heat from the pipes. We had the only eco friendly refrigerated pool in chch where the water going into the pool was a good 5 to 10 degrees COLDER than the water that was already there. The asphalt did not care where the heat came from, it simply continued to absorb it....Upside was we had a practical example of a heat pump cycle and how refrigerators work for science class.....Quote:
