https://ieefa.org/resources/carbon-capture-has-long-history-failure Seems great to help recover more oil from semi-depleted wells. Even that is is not as good as just leaving a field to grow whatever happens there naturally, usually trees. There is so much bollocks spoken about carbon capture and how just capturing from the exhausts and pumping it underground solves the problem. Just another layer of technical complexity and expense. Seems mad when we already have the technology we need.

You will end up getting one in the end. I bought a cheap one, soon packed up.

Skew may be useful.

Not a contiguous period, just the sampling averages (around every 8 seconds). A fridge, if working properly and not installed next to something hot i.e. radiator, oven, over UFH, will consume very little. Especially if it is full of stuff. Most food is water, so lots of energy transfer is needed to change the temp by 1⁰C. Thinking about it a bit more, a period of zero draw cannot be considered base load. It could be included in the under 100 W range (or 50 W, or 300 W). My fridge has a mean power draw of about 8 W.

I have often thought something along those lines should be easy to do. Cars use a similar idea in the Mass Airflow Meter. I tried to make an ultrasound one. Never got it to work. https://hackaday.com/2013/08/21/ultrasonic-anemometer-for-an-absurdly-accurate-weather-station/ May have to revisit it sometime.

Where you need to use a distribution. Here is mine for 2019. Just be careful with the x-axis as it doubles in value for each bin. You can see when the DHW is on (3200 bin) DHW and 1 storage heater (6400 bin) and DHW, both storage heater and the washing machine (12800 bin). Really hard to tell if base load should be 0 W (0 bin), greater than 0 W and up to 50 W (50 bin). The means are 0W 54%, >0 <=50 15.2%. At nearly 15.2% below 50W, over a year, that is a maximum of 66 kWh, or 0.2 kWh/day, which is not far off what my fridge uses (bit more in the summer, bit less in the winter). My fridge is the only think that can come on when it wants to.

A Davis Vantage Pro2 is what you need, can interface directly with an RPi. Have you looked at WeatherUnderground to see what weather stations are near you, and what sort they are. You can sometimes get the info on the hardware they are using.

What are yo trying to achieve?

Not for a house that I know off. There could be a number of different way to define it being the problem. Should it be just the essentials that have to stay on i.e. a fridge and lighting. Then the secondary essentials i.e. freezer, cooking and DHW. Then the nice to haves i.e. central heating, treatment plants, MVHR/Ventilation. Dish and clothes washing. Then the discretionary stuff i.e. entertainment, swimming pools, A/C.

If that was a reply to me, then no. The 0.1 kW is the mean load for everything. It is actually a little higher but I rounded the result, use about 3.3 kWh/day, so about 138 W. It could be argued that at nearly 70% of the time I draw no power at all, my base load is 0 W.

There was a time I had no idea how to make one. A DS18B20 based temperature logger was the second project I did. The advantage of making your own is that code is easily available (could post mine up) and if you use a Raspberry Pi W of some sort, you have bluetooth and wifi built in.

What is the £/Wp price, that is what really governs it unless you can use all the power they generate, all the time.

Have they come back onto the market. There was a push on them a decade ago, so probably old stock.

@Alan Ambrose So last weeks usage. Mean power draw of 0.1 kW, so 16.8 kWh for the week, 7 kWh day usage and the remaining 16.8 kWh night usage. 69% of the samples are Zero Power (78,931 samples, mean sample time 7.7 seconds).

No

Run the details though here. https://www.tlc-direct.co.uk/Technical/Charts/VoltageDrop.html

Physics explains it all.

Discussed quite a lot in the more academic circles and policy making committees. Only over the first decade or so. Can't remember the actual number if decades where it equalises with CO2, but seem to remember it was between 2 and 4. Worth remembering that a rise in temperature today is much more damaging than the same rise spread over a few decades. It is the rate of change that is important, rather than the absolute rise in temperature. Given enough time humans, and a lot of wildlife/plant life can adapt.

Why you have to take the option away from them, not going to happen on its own.

London, the classy bits

Brings up an interesting point. If we burn fossil fuels to heat buildings, we can relatively easily work out the efficiency of the delivered energy. How should that be calculated with renewables. Wind turbines have a theoretical limit, and an in situ capacity factor. Solar is similar. Large scale hydro has a huge catchment area, as well as the reservoir area. How do we calculate the primary energy of that. Should we take in all the potential energies involved, or just the turbine efficiency, as the primary source. Then what happens with by products. A dam may make for better agricultural irrigation, rather than pumping ground water. Going to take a lot of thinking about.

Just by chance this bit if foam had washed up. Probably bouncy from a small boat. Can see that the surface has degraded and the initial mounding was sub standard.

Me to. Still use them, especially this one. Means 'stop blocking the empty fast lane of the dual carriageway'. Unlike this one: Which means 'I know I have been a complete twat and purposely held everyone up, but I am more important than you'.

I do. Shall post something up when I get back home.
