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.

Does seem that you value convenience over energy costs. Look at a new printer, they are still pretty cheap. I have a tiny wireless router that connects to all the RPis. The energy usage is really too small to measure, may try to measure it again now I have a better meter. Later today I shall have a look at last week's zero power draw (less than 1 Wh), think the last time I looked it was over 60% of the time. Not having stuff on is the real secret.

Did this exercise over a decade ago. I have virtually no parasitic loads now. Rather than look to power it renewably, is there anything that can be properly switched off i.e. printer. How about a bit of electronics that senses one half of a co dependant bit of equipment that turns on the other bit i.e TV and satellite box or sound system. As nice as it is to have everything instantaneously available all the time, a few seconds wait is not a killer. Was only 45 years ago we had to warm up the TV.

Or worse, Micklefield.

I took my driving test in High Wycombe, so ever start was a hill start. I failed first time, must get around to redoing it.

The W [watt] is the power, kWh [mega joules] is the energy required. If the W is 'on' for 1000 hours, then that is 1 kWh of energy [kWh or MJ] is just power multiplied by time (the k just means multiplied by 1000).

3m³/m².hour @50Pa and 3 ACH are not the same thing (something I forgot earlier) The first is based on total area and the other is on total volume if I remember correctly.

Must watch Dante's Inferno before I go there.

Wash your mouth out with soap, we all really know that ill informed opinion is the ultimate truth.

I thought JFC was a fried chicken shop.

Also worth noting that if you wear cloths, they are insulation you to a certain extent from the radiative heating. One also breaths in cooler air, so your body has to work harder to keep the core temperature up. Yes, so often forgotten. Why the sun does not fry the Earth, we are a long way off and only getting a very small fraction of the power it radiates. If you can see an element glowing, it is in the visible light part of the spectrum. IR is invisible to the human eye. The shorter the wavelength, the more power there is. So may be better off putting in sunbed lamps, they emit UV, so higher up the spectrum. And you will get a 'healthy' tan after 40 minutes. So it was acting as a convection heater.

Getting into the territory that walls that are colder than the air temperature, and body temperature, can actually efficiently heat people up via IR wavelengths. Many people think it works and claim it is a good reason to have 'lots of thermal mass'. See here: energy and light

More to the point.

We see similar problems on here ever week. Is gas cheaper than ASHP, Radiators or UFH. A day studying very, very basic thermodynamics and energy production would solve that problem for ever.
