I heard that the CLIC cancer charity had to change names from Cancer and Leukemia in Teenagers. Why is Exeter University so up itself?

Like asthma caused by the fungi.

I can be a bit off with quips. Having renovated 3 old buildings in the past, I would say yes, not worth the effort. In hindsight, the last one I did, I should have gutted out and then dealt with the core problems, the lack of foundation (was a 1860's stable block converted into 6 cottages. Built on the old beach in Weymouth). I like modern materials, they can easily be shaped to look like an old building. It really should not be hard to build an airtight, and therefore watertight, box. Then add things to make it look pretty.

First thing is to look for any very obvious leaks. Damp and mould is really the secondary sign there is a problem. Then knock down and rebuild to modern standards.

No, was there a decade ago doing my Masters, then it was a miserable building down the arse end, as far from the car park (they charged) as possible. I have been to the 'innovation centre' should be called 'hopeless dreamers'. Is the Falmouth one where the art goes on?

A door needs to be accessible from outside. Here is my secret code, it is embedded in the shame.

I am watching paint dry (literally), so have just read (skimmed) a paper about embodied energy to make Lithium Ion batteries. The materials takes 391 Wh to deliver 1Wh The processing takes 763 Wh to deliver 1Wh Total is 1154 Wh/Wh. https://www.sciencedirect.com/science/article/pii/S2212827119301015 So as soon as you have 'used' the battery 1200 times, you should be into energy negative. The interesting thing is that the vast majority of the energy is in the processing, this will only come down in the future, and, so say the old worn out meme, if that energy comes from a low CO2e source, it does not matter too much environmentally.

The very first commercial wind turbine was installed down here, between Falmouth and Helston at Sewogan. It sat unused for decades, but I think it has gone now. Was pretty ugly.

It is always a problem in small houses, but even worse when the place is longer and thinner. My house is 3.5m wide, almost a metre is taken up by staircase, leaving 2.5m. Pop a sofa in, and now down to 1.25m (ish). Put a TV in and you are about a metre from it. I don't have a TV. The point I was making, was that for the same area, layout can be a lot better than what I currently have. I only have one bathroom, and very little storage.

Vaguely. I found Penryn campus a bit of a rip off all over. Was not a happy time in my life down in the Geography department. They charged extra to put butter in a bacon sandwich.

It should be, though if the fan is out of balance, or the case not fitted correctly, then it could make more noise. You probably have, there are thousands used as A/C units. Usually a few feet up a wall. Have a look around bars, small supermarkets, offices.

Prepared or forced.

They just don't. It is all to do with the area they present to the wind and the windspeed.

Had this conversation with @caliwag His idea of small, and mine are different.

Wet, windy, warm and sometimes sun. Not even thought about heating for months now.

May depend where you live. Near a busy road, or an arable farm, or very close to the sea. All those throw up a lot of particles, all the time. I live just off one of the most polluted roads in the UK, hard to believe that in windy, wet Cornwall. The dirt I get in my windows is the worse I have known.

You knocked out the traffic lights in Truro, which is 50 miles from you. And they blamed it on a windfarm and a gas plant, now we know the truth. Shall we call it the 3C event.

Does that mean getting rid of a cooker and fridge, eating out every day instead. Using a launderette is just horrible, I have often thought they could be improved, and incorporated into cafes. Where do you put the eBike in a small flat. I did minimal living when I was a young student, probably the biggest single thing I had to move was my stereo. No, I shall stick by my statement that we need to build bigger places. Building smaller places does not reduce price, that is set my how much people can borrow. If people could swap excess assets for 'experiences', that would cause a lot of environmental damage from the extra transport alone. That is before the extra consumerism.

He thinks it is always worth paying for a professional. Then he goes on to relate a story about an estimator adding 20%, passing it onto the boss, who adds another 20%. Says it then comes in on budget.

For anyone interested it goes into supporting professionals because they never get the estimate wrong. https://www.bbc.co.uk/sounds/play/m0007djl

Traders may not see it that way, they could capitalise on the the public's ignorance. I see to remember that happened after 'D' Day. 240 old pence to the pound was rounded to 100 new pence to the pound. I know of a warehouse

Well yes, that is what they are for. But you can loose the output, or a high proportion of the output, for very little shading. I installed a small, off grid, system. When I went back to look at it a few weeks later because it 'had stopped charging the battery', I found a few dockleafs had shaded a corner. What was really interesting though, was just how hot that module had got, way too hot to put your hand on, so over 70°C. One of the problems of shading is that users are used to it. This is mainly because the shading has always been there, so they do not know what the system could produce. The upside is that we have a lot of overcast days in the UK, so on these sort of days, less, or no shadow is cast.

Even with optimisers you still get a hit that is out of proportion to the optimal. I think we have done this conversation before.

How badly shaded is it? It only takes a small bit of shading to have a huge impact on performance. Does your inverter/inverters have the ability to log long term performance data, text files are best as that can be easily manipulated in a spreadsheet.

I have downloaded and installed Andoid Studio, that seems to have SDK in it. That makes sense, but how to I add in things like the camera, GPS and then, and this is probably the easy bit, make some code to do what I want it to do.
