Re: [EVGRAY] The barn board going on

Body

JamesThe wind around here is fearsome.It is hard to believe people settled on such a place, I think, sometimes.I designed and built wind generators for years, and used them for decades, before cheap, and efficient photo voltaic panels came out.Like solar cells, they work, but I think we can do even better understanding the true nature of where energy emerges.By all means, exploit everything out there, rather than pay the power company.However, we are very, very, close to solving a major world problem, and should keep at it.Cheers Warren

Hi guysThe big hundred and seventy year old barn is getting a new lease on life, along with the stone barn, which is to be my workshop.It has been a huge job this year, to do this before the snow comes.You can just see the heat pump mounted at the extreme right of the photo. This is a air to liquid heat pump which can take heat out of the air down to -30 C. This heat is stored in an ordinary electric domestic hot water tank, and then circulated through high temperature plastic tubes cast inside 5" of re-enforced concrete floor.It is underground cable grid power for now, but since the roof faces just the correct angle to the Southern sun, I want to put solar voltaic panels up there.Since I have the resistance elements already, in the hot water tank, they would be an ideal way of testing Rosemary's 17x circuits.The big barn roof is getting replaced in a few weeks, with heavy ribbed steel, as we straighten the roof rafters up there, and put new strapping timbers to fasten it to.I just have to put another window in the stone barn, and fit the doors in place. Oh, and a wood stove, to try to burn all the rubbish wood.Getting my machine shop machines, and electronics bench back in play will be so good.Cheers Warren
