  1. Right, yes, I remember now. Can you fit mirrors, plastic ones. They will work.
  2. Were you now. Not followed your build too closely, but as a general rule, the more insulation you put in, the lower the temperature change will be, it is what insulation does after all. Wood fibre, like timber, has strong hydrogen bonds in it, this is good for storing thermal energy, and if it is stored, it is not transmitting though. So the more wood fibre you can get in, the better. As it is a roof, can you reduce the amount of direct sunlight that is hitting it. PV modules are good for this, and you can use that excess energy to run an AC unit, or just a large fan blowing in air from the North (though this will only drop the interior temperature to that of the outside). A reflective roof covering would also work as well.
  3. Was that not called 'The Spastic Society'. There was a shoppe in Amersham called Scope in the 1970s. They sold damaged kitchenware. Not sure if there is a connection.
  4. Not till tonight, I am not on split shifts untill tomorrow. Cooking is easy. It really is. It is just a case of being organised and not overly ambitious. The rest is physics.
  5. You will need to flesh that statement out to support your claims. Electricity, in the UK, is now below 300g/kWh. A gas boiler is around 225g/kWh. There is not much scope to improve a gas boiler, and if the SCoP of an ASHP stays at 3, it is still twice as good. Going to revise that 300g number after checking. 181g/kWh last year. So even resistance heating in a leaky house is better than gas.
  6. I have not had a freezer for 20 years or so. I did have a 24/7 Tesco nearby. Dried and tinned food is just as tasty, and takes no energy to store it. Also, if the door falls off my cup board, my food is still fine. The first friend you make if you own a restaurant is your refrigeration company.
  7. We get our fats and oils collected, sometimes we get money for it. I seem to remember that it is only financially viable when crude is over $120/barrel (currently $77). A few years back (2006 I think) there was a spike in oil prices caused by lack of refining and storage capacity, unfortunately this was miss reported as 'peak oil' and the world went crazy for bio fuels. This lead to speculators moving in and buying up farming capacity to grow oil crops. Thankfully it did not last long or we would now be back to 1970s food prices. We currently use about 100 million barrels a day. There is 1.7 MWh of energy in a barrel. About 50% of a barrel can be converted to gasoline or diesel, so my car, which uses about 500 imperial gallons a year, or 2,270 litres. That has about 9.7 kWh/litre, so about 22 MWh. So about the same energy as 13 barrels, or 26 after refining. I think a standard oil barrel is 22.5 inches diameter and 33.5 inches high (55 US gallons), so an area of around a quarter of a square metre. Could fit a years worth of transport oil in my small shed. Can see why we use oil.
  8. Take that with a pinch of salt.
  9. The problem with kitchens is that styles change. My sister's 1st husband made his own. Then years later, made some more parts to extend it. £5k buys some good woodworking machinery and a lot of timber. When I had my house valued a few years back, the estate agent said she loved my kitchen. It was the original one put in in 1987.
  10. This is my work area, I can do 200 meals in 4 hours from it. Go temporary. And freestanding.
  11. Have you looked at the price of a new boiler without using the loan scheme. It may work out cheaper.

  13. In the undergrowth upon the lady's front garden I find best.
  14. It is near Scunthorpe
  15. Won't be as unsightly as an PV and ST set at an angle on your flat room. The noise issue is just not there on modern ones. Planning should not refuse it if follow the MCS installation guidance, the government has set a target to install 600,000 of them a year. I would have thought that you could get a tip top system for a couple of thousand. Just hunt around on eBay to see what the component parts cost. They do take annual maintenance
  16. And little work was done. People often forget that supply and demand is governed by demand. Now while a few people will pay over the odds to get something finished, most won't. If this was not so, we would all be infinitely cash rich with unlimited wealth.
  17. I think you would have a highly compromised PV system. You may be better off, and this may sound odd, with a ST because when the sun does hit it, they can deliver a lot of power. So may well contribute to water heating more. An ST system can be fixed at an optimal angle and will be smaller overall. Though a simple ASHP dedicated to DHW may be more cost effective overall.
  18. Did I not say that if material prices go up, labour prices will drop. All comes down to the money supply. If people only have 100 quid to spend, no good hoping they will pay 110.
  19. The alternative is worse: no development. While I agree that building poor quality is unnecessary, housing people is more important than reducing new housing energy losses. Let the power generation companies clean up that sector and then the problem goes away. No point diverting resources to where it is ultimately not needed. Or just ban combustion technologies. Problem sorted.
  20. Just trying to right a social injustice. Have to declare it every time I go for a teaching job. Can make up any story as no one actually checks it out, as long as it does not involve children and genitalia, no one cares much.
  21. Or The Eagles's Last Resort. Interesting but in bold. She came from Providence One in Rhode Island Where the old world shadows hang heavy in the air She packed her hopes and dreams like a refugee Just as her father came across the sea She heard about a place people were smiling Spoke about the red man's ways How they loved the land They came from everywhere to the great divide Seeking a place to stand or a place to hide Down in the crowded bars out for a good time Can't wait to tell you all what it's like up there They called it paradise I don't know why Somebody laid the mountains low while the town got high Then the chilly winds blew down across the desert Through the canyons of the coast to the Malibu Where the pretty people play hungry for power To light their neon way give them things to do Some rich man came and raped the land nobody caught 'em Put up a bunch of ugly boxes Jesus people bought 'em They called it paradise the place to be They watched the hazy sun sinking in the sea We can leave it all behind sail to Lahaina Just like the missionaries did so many years ago They even brought a neon sign that said Jesus is coming Brought the white man's burden down Brought the white man's reign Who will provide the grand design what is yours and what is mine? Cause there is no more new frontier we have got to make it here Satisfy our endless needs and justify our bloody deeds In the name of destiny and in the name of God (Aaah...) And you can see them there on Sunday morning (Aaah...) Stand up and sing about what it's like up there (Aaah...) They called it paradise I don't know why (Aaah...) Call some place paradise kiss it goodbye... Ah-ah-ah... ah-ah-ah... Ooh... hoo... Ooh... hoo... Ooh... Ooh... Ah-ha... ooh... Ah... ha...

  22. CPS as in closed panel system, is not the same as CPS, that bound me over to keep the peace for 12 months. But no fine, so pretty cheap in comparison.
  23. There are shading issues to consider. Tracking systems are usually used in fields where the modules are spaced apart, so when the sun is below peak altitude, one module does not cast a shadow on another. Shading is the killer for PV performance. You could consider putting a fall on the roof, say 15⁰, this is to let rain flow away and take the buildup of dirt with it. But you still have to be wary of shadows caused by the roof ridge, and nearby buildings. This may be a case where individual module inverters work well. A sketch would help.
  24. Mass and wind loading are the two things that I can think of, this would mean you need a reinforced roof. A sketch of the roof would help.
  25. Are you thinking of laying the modules flat? This may impair their performance.
