I often upgrade my thoughts and opinions. Not as often as I downgrade them though. In my mind, I have upgraded my car to a Porche, in reality, it is a rattle C-Max (which is in the garage at the moment to cure the rattle). Reality kicks in when I take a corner too fast.

I thought it was 'high fences make for good neighbours'.

Sound all very expensive.

Get your university to pay for it, or you will be living in a cabane in the Bois de Fontainebleau.

Not at all, I like that idea. I have a mirror hanging on my neighbours fence. It reflects light onto the back of the bamboo, where an echium if growing.

That is a brilliant idea. Cover the problem over.

This neighbour, is he called Boris?

I think that one problem of being 'off grid' is that people expect to get the same controllable levels of comfort that we have all come to expect. It really does not matter of your house swings 4°C in temperature day to day, or you have to take a short shower, instead of 3 baths. When I was a student in the early 1980s, we had flat that had a 2 kW bar heater in it, that was it, apart from the cooker. We survived, through studying, fresh vegetables (one flat mate was a farmer) and alcohol (2 other flat mates died from it, eventually). Just a change of lifestyle, and thermal underwear.

Shop in Market Jew Street has this.

Insulate it and use it as a thermal store, or other energy storage.

Chalfont St Giles.

Needs a huge amount of insulation under it, and to the sides, as well.

Is that purely heat pump driven, or does it use the built in resistance heater as well? i.e. it has a CoP of 1 at 60°C.

Nor me, or landmines. A more manly method.

I think so. Basically you need to be able to isolate the inverter from both the AC and the DC sides. Just remember that if the inverter is working, isolate on the AC side first.

No, thermal bridges are places where you have a larger than normal surface area. So corners and internal walls where they meet external walls. Basically any uninsulated areas that protrude. Airtightness is purely the ventilation. You need to control ventilation, not let just random holes and joints govern the infiltration. Airtightness also improves sound insulation. Have you started to think about sound transmission. You my find that mineral wool is better than rigid board. There are also 'resilience' bars that decouple ceilings and plasterboard walls.

Because the inverter supplies at a slightly higher voltage. Electricity takes the path of least resistance.

You could use a CHP unit to generate electricity and supply thermal energy. A diesel one would be reasonably cheap to run.

Himalayan sea salt, but only works if you pronounce it correctly, otherwise it is just salt.

Or dream? Now that is an idea worth pursuing. Flashing website, nice write up by a recent graduate in Marketing and PR. Get millionaire investors on board, then retire. No need to actually sell any hardware. Seems to have worked for many companies that are going to save the planet.

What are you doing about moisture/vapour control. While Paris is not that far South of London, the climate is quite different. Higher summer humidity and temperature, colder and dryer winters. Spring time, just pollen.

I would hate to buy one and they stop the cloud service, or updates to the phone software.

Latent heat of fusion. It gives up many times the normal amount of stored energy. Now, if only there was a cheap, easily available, material that could phase change at relatively low temperatures, say 100°C, and then could take extra energy up to say, 10 bar. Could pipe that though an engine easily enough I would have thought.

Invest in a wind or solar farm.

https://polarnightenergy.fi/ A website full of puff. 99% efficiency. Maybe during the first °C of storage. I am surprised this kind of nonsense is reported. If it was possible to store any material at 500°C+ for any reasonable amount of time, then the "energy crisis" would be over.
