Can you not receive any financial help from the heritage people or the government? thats if its eligible.

My first recollection of tinkering was wiring a 240v radio cord to a 9v motor to my technic Lego truck, it ended with setting the kitchen on fire!............................I couldn't sit down for two days!

Looks like a great set up there, very jealous.
Have you got more pictures of the set up, gen sets etc please.
Many thanks
Jonathan

im in the process of a re-build in the gennies - so the old system is a bit out of dats - and a bit rubbish. Hindsight is a great thing isnt it  Guy |

So will they then stick their beaks in when it's 100% pristine & make demands thereafter?
OR do they simply not give a damn?

Excellent projects - well done indeed.
Any estimates of the man hours involved in all the work?

No - but its a hell of a lot. The leat rebuild took 100 tons of sand, 5 blokes, 5 days a week, for 5 months, 8 hours a day. (1000 man hours) - the wheel took probably 4 to 6 weeks, 2 blokes.

Guy
have an APPLAUD! Definitely a contender for the most interesting project on the forum. Any chance of a grand opening?

Well done, thats great
all you need now is shed loads of water for ever and 48 generating hours in a day

Grand opening? Its open! im still mucking about with the generators, I havent got the gearing right (currently victorian chain 10:1 drive to layshaft, then 800mm diameter pulley driving V belt to 00mm pulleys on 1.5kw turbine heads (x2) at 500volts output)
It seems that the gennies are better at 450 - 500 volts (more efficient) than they are at 300 - 350 volts, by a factor of double. The inverter will convert 300 or 500v DC to 240VAC pretty much the same, but if I adjust the power curve, so they make 300v, I get 500 watts, conversely at 500v I get 1000 watts. yet at the 500v speed, the wheel is turning much too quickly, and theres loads of splash loss - so it should be making less power... i need to speed up the gennies even more in relation to the wheel...

The noise of the water wheel is not sufficient to cover the noise of the GSHP? Does that mean the wheel is quite quiet or the GSHP is bloody noisy? (Or they are a long way apart)?

the gshp is bloody noisy and inside - the wheel is soothing (to me) and a chufchufchuf noise like a steam engine - the gshp is grrrrrrrrrrrr like a 2 stroke suitcase genny current plan is to add a 9:1 gearbox to the drivetrain which I have. thus slowing the wheel down by a factor of 9 - thus filling the buckets up properly (its currently about 2" deep in each bucket) and the maths shows theres at least 1.5kw available (inc a 60% efficiency rating) yet Im getting 600 watts  But a 9 ratio of slowing might be too much, so I might re-wire the gennies to delta instead of star / wye. I have found that the gennies run best at 500ish volts (over voltage kicks in at 510 volts) |

Ok - update time. Little gennies replaced by big f-off DC electric motor-as-generator. This is driven by a belt from the large pulley you have seen previously, to a smaller pulley on the side of the 9:1 gearbox. The motor is then driven from the gearbox via a 'tyre coupling' allowing torsional movement and axial misalignment I had a spider coupling on there - but it was noisy - so replaced with the tyre - sooooo much quieter! 2 x SPA 3350 long belts power this. Chain replaced with FREE replacement from The Diamond Chain company - thanks guys! Its a standard ANSI chain - and is a close enough fit not to worry. Small sprocket is new, and ANSI spec. Bearing for the layshaft has been replaced from the bronze bearings to a pair of shiny new (bloomin' expensive) pillow block bearings (SKF). I have learnt, with this sort of stuff - that cheap bearings don't pay - buy the best (RHP/SKF etc). When things go wrong, they go horribly wrong. Making 1.3kw now 24/7  But at about 20 or 30% efficiency - so new generator (Ginlong) is on the slow-boat-from-china. |
