Hi all, I can put in a warm recommendation for HiPower hydro systems. I put mine in three years ago and can only complain that I wish I'd known how to spec my needs--by reading this list--before I got it. I have 900 feet of 2'' black PVC pipe running along a creek's headwaters for 250 feet of vertical head. My water supply ranges from 120+ gallons per minute down to nothing for 3 to 5 months of the year (my apologies for incompetance with metric equivalencies). My spring and springbox is 1/3 of a mile from my house, and my system powers three households through the winter--including one almost a mile away! My poly pipe and current nozzles don't convey much more than 60 gpm, so I've got resource awasting until I put in another parallel pipe. But high spikes of flow don't last more than a week or three, so I'm not desperate to do the work yet. The 60 gpm yields about 64 14-volt amps--that's 900 watts 24/7 through the darkest months of winter. The dump load helps heat my barn office via a 110-volt ceramic heater.
Derek makes a 3-phase unregulated 110 AC power feed--the 'wild' 110 alternating current is generated by the magnets' velocity in the industrial motor that acts as power generator. This means its cycles per second vary with power production. Which doesn't matter, since the AC is transformed to Direct Current for battery storage as soon as it arrives down the power lines, which are just #12 Romex, thin things with little line loss up to a mile. There are inefficiencies in this double conversion from AC to DC and back again, but modern inverters and electronics make it, I don't know, it seems like roughly more than two thirds efficient power delivery. My system has only had material and Godly breakdowns in three years--hose clamps worked loose, uncatastrophic lightning strikes, nothing electronic. I love it! I'd note that one of Derek's specialties is delivery to multiple locations--each of the three phase wires may go to a different destination--which provides great opportunities. For me, I've got a great spring but only 30' of head on my property. By borrowing my neighbor's gravity below me, and delivering painless juice to him in return for it, while managing the system entirely inside my barn, we all get a lot more than any of us could individually. btw Derek uses Harris Pelton wheels and housings, so I feel like I'm getting the best of both these enormously talented microhydro pioneers. Feel free to ask me about any particulars. Electrons For all! Charley [email protected] wrote: > >There are 3 messages in this issue. > >Topics in this digest: > > 1.
