Someone posted up about a new inverter that got rid of the 'magnetics'. Getting rid of the capacitors is what is needed. Or at least a simple replacement service pack.

They work ok in deserts, so I think the UK climate poses little challenge. Now the inverter on the other hand is better off kept as cool as possible, especially if it is limiting output. I have get to see some decent, public data on inverter life.

Too right. It is a combination of angles, hours of daylight, ambient temperature and cloudiness. Though I think my peak generation month is June. Not checked for years.

You were lucky, when my sister met him, he pulled out his bible (about 1970). At least it was not his colostomy bag.

probably because it does not have a real CO2 sensor, but one that measures H and then makes assumptions.

Does it log the data, in English?

You going to put up circuit diagram, code and parts list.

Depends on the filter medium. Some is just the same stuff all the way through. Others use a courser filter first, then progressively finer. The only time a single medium filter may cause a problem is if it has a supporting cage and different seals in one side.

It is because measuring carbon dioxide is expensive. Relative humidity is a good proxy though and will tell you all you need to know in practice.

Does out need to be glass, could you make it from cast acrylic. Walk in glazing would do it.

That is a totally different problem. Not one they have with the front window of the Intercity 125 trains.

Basically what I heat my home with, just mine are storage heaters. My house is not new or passive.

Um Been discussed a fair bit. If you see the term 'far infrared', be wary.

Were you thinking he could warm his acid bath water with some?

That is quite a lot of power. How far can it be throttled back? Just had a look at the data sheet, 3.8e and 12.2h Which is still quite a lot. Ask @scottishjohnto knock something up from a small outboard motor.

I agree with that. Though sometimes harder to work out on a time series. I think it could be worked out from the GridWatch data as that gives generation by type at the 5 minute interval, as well as demand.

Interested in how you calculated the 13 tonnes of carbon dioxide. There were many times this year when we had very low fossil fuel usage, this reduced the carbon dioxide per MWh considerably. There are also regional variations. A quick look at intensity.org.uk shows that the South East, where you are, has a CI of 245g/kWh. South West, where I am is 78g/kWh. So your 5 MWh is worth 1225 kg saving, mine is 390 kg. A third of yours. Makes investing in personal RE for carbon dioxide saving rather marginal. @Ed Davies is the person that has looked at marginal differences in grid intensity.

How does it know what information you want? Not saying this mirror project is a replacement for home automation, or even a replacement for a notebook, pencil or diary. Just thought it as a nice combination of two existing technologies. One fairly old, and the other very old.

And everyone in their back offices can have a good laugh at what you are saying.

Can you just create an artificial island and let the ducks build their own home.

Well yes, but we are where we are, so short of pulling down all the hopelessly small places (a policy I am not against), we have to make places as useful as homes as possible. Not that long ago, before the Sunamp was about, your general advice was to go for a combi gas boiler (if there was gas). Just because there is a lack of imagination in the design of retrofit UFH, does not mean that it is totally unsuitable. I am not claiming that a restively heated, wet UFH is the only, or compulsory heating solution, just that it should be researched seriously for a small home.

I agree, but if we constantly keep bodgeing and compromising, we will get nowhere. Sometimes, we just have to bite the bullet and do the right thing. Often too much emphasis is put on price and not what is best for the occupants.

I don't think you realise just how restricted a badly designed, 48 square metre, 2 bed, terraced house can be. Even windows get in the way.

@MikeSharp01 Ok, I seem to remember reading about this once. All a bit Boogie Nights having mirrors and cameras. I was just thinking of some weather and energy data, maybe a reminder of two. But maybe a plug in that films the missus could be the solution to the problem that @ProDavewants, they have long winters where he lives.
