Possibly. Though the majority of the generation will be in summer, so may make less difference than you think. Go and play about on the PVGIS site and see what the numbers show.

Engineering and lecturing. And catering and dropping out of the rat race at a decent age. I could have invented the term FIRE, but I was too busy dropping out of mainstream work.

Heard that too, and remember some old cottage gardener saying he used potatoes to break up his soil.

They have a way of dealing with that, nothing, apart from pain management and a bed was going to happen before £8000 was deposited. I suspect that as my Aunt is British, she could have had it for free anyway, but the insurance gave her a room to herself.

Here is an interesting challenge for you (I am a bit busy right now). Does that change for an equal latitude in the Southern Hemisphere? I am wondering how much difference the weather makes? I could get posh and start talking about seasonal turbidity, but cloudiness is a better word. The UK is particularly cloudy, but never looked at similar positions in the Southern Hemisphere (as it is mostly water), but maybe places in Russia and Canada that are at a similar latitude have very different figures.

Probably covering his arse, I would do the same if I was not paying the bill.

I think they would be a relatively quick way of drying up, and breaking up, some boggy land. Would need to be chopped down after about 5 years or so, then more interesting things done.

Yes, or 10 300 W loads for an hour, or a 30 W load, like the security light I have just fitted for my Mother, for 100 hours. More interesting is how much water and air you can heat up. Water takes 4.2 kJ.kg-1.K-1, air is easier to remember as it is 1 kJ.kg-1.K-1, but oddly, stone, concrete and brick are less at about 0.8 kJ.kg-1.K-1, pine is 1.5 kJ.kg-1.K-1. Taking just water as an example, and 100 litres (or kg as it is the same) of water at 40°C and an incoming mains water temperature of 10°C That would be: 4.2 [kJ.kg-1.K-1] x 100 [kg] x (40 - 10) [ΔK] 12,600 kJ To convert from kJ to kWh multiply by 0.00027778 3.5 kWh So today, your PV has given you a free bath. (If you take the reciprocal of 0.00027778, you get 3,600, which is the number of seconds in an hour)

This is why kWh can seem a bit confusing to a lot of people. It is Power x Time, so even a lower power in the summer can produce a greater amount of energy. Energy can be measured in kWh, though is really MJ (Mega joules). There is a direct conversion between MJ and kWh, basically the time cancels out. This is because a W is a J.s-1 and an hour is 3600 seconds.

Makes a big difference, so you are comparing probably 14 hours of productive daylight with about 8 hours today.

I am up at my Mother's as after a month, my Aunt, who broke her leg while staying, is just fit enough to travel back to Canada. The bill is large as she had to have her hip replacement, replaced, again. So at about £35,000 from her insurance company, the NHS have done quite nicely out of it (one of my Cousins is a GP and she think the bill in Canada would be about the same, but in $C, but one of my other Cousins lives in the USA, a CAT scan starts at $35,000)

Are they actually doing that, or just seem to. Modules are rated at a particular light intensity i.e. 800 or 1000 W.m-2. In summer, levels may be higher than that. Basically yes, and the sun has to travel through more atmosphere before it hits the module. Go and find your nearest WeatherUnderground weather station that has a PV monitor and look at the historic data. It is measured in the horizontal, rather than the optimal angle. Then go and look, and play about with PVGIS and see what changing the azimuth and altitude of modules would do to production. Also, is the 6 kW and 3.5 kW really that, or kWh. If kWh, then that is partly down to shorter hours of daylight.

Get those willows, poplars, eucalyptus and Leylandii planted.

It will all be ok as Boris is not cutting corporation tax now as promised, but is going to spend the 2% difference on the NHS. Apparently that is £6bn. Is that on top of the £18bn bus promise. A 30% increase, I better go and break something.

Even that went from a polluted brown field to production in about 4 years. There is the last tin mine that was productive. For the last 20+ years there has been arguements about reopening it. Latest twist us that they could not build housing nearby because if the noise that the mine may make. 20 (expletive deleted)ing years to do nothing, the UK really had to get a grip on development and rethink our planning system which is hurting the country at every level.

Also, as a rule of thumb when using CSM, weight it, then weight out twice the amount of resin. You won't be far out.

It is a bit if a combination of things. RH is really only a problem when very high, and in a hot place. If you warm the boards, curing can start sooner on the first layer. But don't think that will be a problem. What may be worth while is upping the catalyst a bit if the final layer is put down more that about 15 to 20 minutes after the first layers. Trouble with having the resin warm and the boards cold is that it reduces the pit life of the resin. Do a metre by metre square at a time until you get a feel for what is going on. And don't do too much if there is a chance that it is not going to cure in about an hour and a half. Curing will not catch up the next day. Sun us out in Aylesbury.

It is a combination of pipe diameter, cumalative resistance and pressure. There are two pressures, static (tap closed) and dynamic (tap open). https://www.copely.com/tools/flow-rate-calculator/

So you have now made the sail, get the hang of the GRP and you are well on your way to making a boat. Make sure it is warm enough to lay up the GRP. You could use cobalt accelerator if it looks like the temperature is too low. If very low, then amine accelerator (have used that for very quick repairs when about 0°C.

Heard on the news that the factory in China, which was a field in January is now making cars. From Wikipedia The Shanghai regional government approved the agreement to build the production facility in July 2018, and a long-term lease was signed for about 86 hectares (210 acres) of land in October 2018.[1][3] Construction began in December 2018 with the installation of secure fencing and site offices. The General Assembly Building was nearly complete by August 2019, and manufacturing line equipment was being installed for both batteries and automobiles. News reports in August noted production could start as early as November 2019,[4] and CNBC reports that Tesla is expected to manufacture more than 6000 vehicles at Gigafactory 3 by year-end 2019.[5] The plant had begun initial production of Tesla Model 3 cars by October 2019.[6] How long does it take us to get planning and design a building, let alone build one.

Quick look at a joist calculator and it is the difference between a 2" by 8" and a 2" by 10" But by having an extra meter on width, the stairs could be turned 90°, so shorter joists could be used, so probably not so different. I seem to remember that during mathematics classes there was a problem about making the largest volume container with a fixed amount of material. Was meant to show the power of calculus. https://www.analyzemath.com/calculus/Problems/maximum_volume_problem.html

I am not 100% sold on that argument. If there was no such thing as a small house, then the replacement would be larger. The price points would be the same as that is what the consumer can afford. The 'loss' would just be on the land value.

Bit of subsidence there.

Not in the ex industrial bit of Cornwall I am in. There are two Cornwalls. The picture postcard one and then the deprived area (one of the most deprived in Europe). To the best of my knowledge, they were built as a test for a new construction method. Then repeated a few thousand times across the county. Thing is, they are not that small compared to some newer places, and quite large compared to some of the old housing (most of Cornwall has only been developed in the last 200 years). I know my neighbour bought his place cheaper than it originally sold for, but that was the early 90's property slump that caused that. I don't think plot prices are reasonably priced, or easy to get hold of, from what I have been told. They are not Mayfair prices, but not giveaway either.

Washer Woman Fingers surely.
