My major loads are at night, but if I look at the fraction of time that I am drawing up to 10W, it is, between 28/06/2019 and 07/07/2019 (last week) 0.6, so 60% of the time. 10W up to 20W is 0.01, 1% of the time. So that is basically the radio, laptop and fridge, toilet MVHR unit. If I look at the same time period, but bin the data into 1kW chunks, then 0W up to 1000W is 0.92, 92% of the time. 1000W up to 2000W is 0.004, so less than 0.5% 2000W to 3000W is 0.05, so 5% (probably kettle and cooking and maybe washing machine) 3000W plus is 0.021, so water heating is around 2% of the time. I need to work on my sub 1000W loads, but mainly below 50W as that accounts for 72% of the time. Radio is 3W, laptop 8W, fridge, on average 5W. But when I look at the numbers at 1W resolution, 60% is between 0 and up to 1W. So I am not going to worry. 60% of the time I use no power at all, I should ask for a reduced meter rental.

Plenty of radon down here, one of natures own nuclear reactor.

Few metres lower, I am always surprised how high I am, probably accounts for the wind and rain.

So 2.55°C different for 200 km West, similar altitude I think (you may be a bit higher), but 25 miles from coast.

For a laugh I have just looked at my external temperature, it is 21.75°C at 11/07/2019 13:47:24 What are other people reading for a similar time?

If we just put PV on our roofs, that would reduce the energy getting though by about 20%. We could also put reflective film on windows, probably cut out 30%. Flooding is probably a bigger risk than drought, but personally I can't see London getting the same climate, or even the same weather as Barcelona. London is in a plain, Barcelona is coastal, but the Med, which is a unique sea. Barcelona is also surrounded by hills. Worth remembering that Barcelona had a lot of infrastructure changes brought about by the Olympics, London did not.

And set up a radio station. The pictures are better on radio.

Mining area here, so all badly polluted, leaks radon, agriculturally worthless (good land is Grade 3b). Or something like this: USS West Mahomet in First World War dazzle camouflage

They didn't collapse then, and they would be bailled out again. I have often wondered if you found a bit of common land, put some plastic pipes in it, cordoned it off with spikes and hi-viz tape, then put some signs up saying: "Contamination Survey: Do not remove" Then, if it does not get disturbed for a year, put a large box filled with concrete on it. Then a shed, then a few piles. Then a bigger shed, but with windows. You get the picture.

Welcome I would spend some time properly learning all you can about building physics and planning law. If you really want to make a difference, get on the local parish council and work your way up the political ladder. There is a serious lack of 'young' people involved in local politics. Failing that, how about a houseboat.

Would you really want that actuator cluttering up the view.

My argument was not to do with the emitter area or temperature, it was to do with the albedo, temperature, area, line of sight and distance of the object receiving the IR.

It is selling the infra red dream again. Work well until you put some clothes on. I really thought this nonsense had been banished, but seems that people think there is a real advantage to it still.

What are these? https://spectrum.ieee.org/nanoclast/green-tech/conservation/graphene-heating-system-dramatically-reduces-home-energy-costs See the disclosure statement.

Do they cover minor damage or are they like Gold car hire, who just say that you damaged it regardless.

What my Father said. Had my cataracted eyeballs changed at 44.

I think, but I am no chemist, that it is the cobalt that is the hard one to get out. There are projects to repurpose old car batteries, but I think that is not the best use for them. There is also the price volatility to take into account. Cobalt is very volatile. Figures from Metalary

I think there is a discrepancy between people that buy new, or fairly new cars, and people that buy end of life cars. Having bought news cars in the past, and see nearly £20k in depreciation over 5 years (same time I bought a holiday home for £36k). I decided that end of life cars were better value. So far the total costs for the last 20 years has been less than the previous depreciation (I do drive like my Mother these days and can get 100,000 miles out of a set of brake pads, they used to last 5,000 miles).

True, but I would probably go to more places if it was cheaper to do so. Motoring distance is often set on a price point, rather than an absolute milage. It is why mean annual mileage has dropped. ONS figures for all 4 wheel cars.

Not sure it does. I has a refueling time advantage, but that is about it. I think even a new Leaf would not last for many miles driven flat out. Would be good to see some data on this aspect. I improved the fuel consumption of my car last week, went from 32 MPG to a shade under 50 MPG now. Had a tuppence ha'penny turbo boost pipe replaced. I find that he generally does what he says, just usually takes a bit more time than we think it should. I do about 2 1/2 times your milage, so that would be 375 charges a year, or 5 years 4 months. My car is already over 13 years old. Not read it, but it just sounded wrong. Kind of thing that petrolheads like spouting as truth. Must be these people. https://en.wikipedia.org/wiki/Institute_for_Energy_Research

I have wanted to do something similar for new products. Most of them are total shit, like my upright vacuum cleaner. The hose goes in at the top, so if vacuuming the stairs, and one starts at the top of them, the f***ing thing falls down on top of you. I can tell you that it really hurts.

Looked at this a few years back with someone else over at the other place. Think we decided that anything less than 2.5MWh for heating and it was not worth while. One of the reasons that I have stuck with basic storage heater on E7.

You can do the same with heating degree days (HDD). It is only good as a rough guide, but may be useful when looking at storage.

Right, got the correct data this time. I think this interseasonal storeage is a statistical problem. There are just not enough times when it is cold to replenish a store sufficiently to be of any use. The below chart is shows the amount of time that a concrete brick is either above external temperature or below it. The trend lines, withing the 1 standard deviation limit, show that as the external temperature gets hotter, there are more times that the block is hotter still. The reverse is true for the cooling side of the equation. There are the odd outliers that pop into the 'the other side', but these are probably rare weather events i.e. snow (had some twice), rain (it can cool things quickly), extra sunny days (had a few last year), very windy days (again, there has been a few, not many this last 12 months).

And according to the internet can clean your bog, patio, coins, cure and give you cancer, cause or reduce obesity, help you concentrate and get a pretty, singing, girlfriend. Ok, I made some of that up. It does go well with a curry though.
