Not such a stupid idea, in a way. You could you that large tin roof to heat an evaporative cooler. https://en.wikipedia.org/wiki/Evaporative_cooler

Welcome. With that much glasing I think you are going to need air conditioning. Have you had all the thermal calculations done yet?

WTF did you use to take that picture with, your doorbell.

Isn't it more financial sustainability as far as councils are concerned. Oh I wish they would bring the community charge back in, would make life so much easier.

Welcome I have a cousin that lives in Wallingford, never been to visit him at home though. So when you say you want to design to PassivHaus principles, which ones are you after? The whole thing except the certification, or more of a A la carte approach?

Not that much larger, on average. Just under 8 m at Weston-Super-Mare today. They work because they are very large. The proposed Severn Estuary barrage would make a lagoon 500 km2, this would give a power range between 8W/m2 (neap tide) and 30W/m2 (spring tide). Cheaper and more effective to put PV and battery storage somewhere.

And objections from government and end users who want cost to be low. On a slightly off topic, but connected. Who sees the irony in this banner on the Humphrey Davy memorial in Penzance. @JSHarris, you are not allowed to answer. Which may give others a clue.

As always, it is not as simple as that. One of the biggest problems is conservationists, they will stop almost all development because some bird or welk may vanish from an estuary.

Not tidal, but there was a land based wave generator based on Islay. https://en.wikipedia.org/wiki/Islay_LIMPET It was the turbine design I liked, simple and worked on both the in and out 'strokes'. There was also a simple design that used a hydrofoil. As the tide went past, it lifted up or down, this was connect hydraulically to s generator on the land. You could take a look at the WaveHub down here at Hayle. They have not generated anything get, except a financial hole.

But what shade of white?

I worked at a model and pattern makers once (well twice). Model makers would work to 5 thousands of an inch, pattern makers to the nearest quarter of an inch. Cabinet makers never did any work, they just sharpened their own chisels all day, and moaned.

Our old mate Joiner used to have a metre rule on the wall, he told everyone to check their own rules and tape against it. "I have 12 inches, but don't use it as a rule"

Erwin Schrödinger's Switch, it is both On and Off. Or should that be @Onoff's Bathroom. It is both finished and unfinished.

Um. https://drivetribe.com/p/germans-make-mistake-fZl0jxc0RKOLdx1lTTvl0Q?iid=B4R_m5lVQ1-Nf8GCJBd4cg

He would have been allowed to keep it if he had changed the design. Trouble was it was a battle of personalities, more than the planning rules.

You could start with putting a small cheap tent on it, then a larger one. See what happens. Keep adding things like caravans and sheds over time. Eventually, no one will take any notice. Then sneak your well camouflaged home in.

As they are down here, even if living in a town. The sustainable aspect of personal transport is quite interesting. We are heading for an all AV future quite rapidly. So the pollution aspect is now rather moot. The congestion aspect is a bit harder, but as I point out to people, Cornwall really does not have a traffic problem. And we get 5 million visitors a year, that is 8.3 times the permanent population.

I had a Wimpey Bender once, it was alright. I miss the 70's, trying to work out what it would be called these days.

Ask @pocster, he knows a thing or two about cheap glazing.

Here is my fan. Been kicking around since March. Got a good bit of dust in it, but hardly a whiff when I switched it on. Had a few embers pop out, wish I had videoed it.

That is the external temperature. I like my house to be around 21°C. Monday was a pretty miserable day, grey and drizzle. Mean temp was 16.5°C, min of 2°C and max of 18°C. House was 18.5°C on average (was painting windows, so they were open most of the day). Min was 17°C and max was 20°C. Apart from the rain, Cornwall has a great climate. And the wind, mist, fog, cloud....

Not my experience. Sometime they smell if I drop sawdust down one in my shed.

Too right, fan heater costs a tenner to buy, even on day rate only about 25p/hour to run. Heats my kitchen up in less than 20 minutes from as cold as it gets. My experience is that, even when I leave the windows open at night, the house is 3°C warmer than outside. So the temperature difference is never quite as bad as it seems. Probably why I don't have to start heating my house until the mean temperature is below 10°C, and that is for when I am sitting and not when I am active. The only downside of fan heaters are the noise, can trip over them (an amazing amount of times in my experience) and if you get one that turns the fan off when it reaches temperature, you can forget to switch it off properly when going out.

So they will be offering even less help now.

check your areas. then multiply by temperature difference and U-value.
