I think we have come across this fellow before, over at the other place.

It is not the filler, it is the cement that is the problem. How much can you reduce the usage to. That will probably give a greater saving. It go for lime. Mix and pour. Wait a year. Repeat process.

I knew a bloke whose father converted horseboxes to campervans. He must have been good as he was featured in Watchdog.

There are some cements that are supposed to be carbon neutral. https://phys.org/news/2015-09-technique-cement-carbon-neutral.html Spoke to this guy a few years back, was very helpful. Not sure if he is still at Sheffield. Dr Ewan A Byars Centre for Cement and Concrete University of Sheffield e.byars@sheffield.ac.uk

Filler, wire brush with the grain, used teabag to stain it. Will still look like a pegboard eventually.

That is my thinking about the melamine faced ply. I am good at cutting wood with a saw, can put mistakes rights with filler, an angle grinder and a palm sander. But I know I am hopeless with a trowel and spreader. Tried plastering 3 times, then got the professionals in. Cost me a lot more as they had to hack of the shit I had put up, and down, and sideways. Plastering is a foul job.

I like paved drives, but did you have a case of the Merkel's when taking the pictures.

I have often wondered by melamine faced ply is not used. We are happy to use it in bathrooms, and our kitchens tops are covered in the same stuff. It is easy to put together and can be easily filled painted over. I suppose Conti-Board gave it a bad name.

Relatively easy to make one with a cheap sensor (DHT22), a cheap board (RaspberryPi Zero or similar) and a solid state switch. With that kit you can also easily expand and add extra sensors i.e air pressure, light sensing, energy monitoring and do some data logging. Quite fun learning how it all works and there are a few people on here that know it inside out.

Don't most modern electric meters have two LEDs on then, one for imports and one for exports. If that is the case, then can't you just sense the pulses and divert accordingly. Easy to count pulses with just about anything.

Then I shall go to Penzance. Was so still there last night that the fireworks got obscured by their own smoke.

Which one? The warm sunny place, or the one in Cornwall?

I did that once. But was only a 3 month job swap, and it was in Sydney

I like that idea, how do I get a job teaching it?

Acrylic is about the only plastic that does not discolour due to UV radiation damage. Not sure about flexible acrylics and the pigments used though. That would need a rapid aging experiment.

No more of a scam that getting your car MOTed though. We all know we can do a better job of it.

My shit don't smell mate. Did a similar thing on my sister's Viva back in the 70's. Tight ropes around it, made sure if it did fall there was a timber pallet to soften the blow. Thing weighed about 25 kg, could easily hold it up with one arm when putting it back.

Work out the dry mass, multiple by the energy content, multiply that by the system efficiency and you have your answer. Takes a lifetime to grow some trees too. I wish people that burn trees would count the rings they have before they throw them on the fire. That may bring home just what an inefficient 'storage and energy' system biomass is.

Tat would be an interesting project. Would need some other inputs, i.e. external temperature, windspeed, shape of building, solar gain, ground temperature, rainfall. Then would need a lot of people to do it for calibration purposes. But fun all the same. I prefer Ed'd idea of letting off a stink bomb and seeing how long it takes to rid of the smell.

That is pretty impressive @Ed Davies, Wonder if you can use a gas analyser and local wind speed as a proxy for air tightness.

is 15 mm about 5/8th of an inch, which is probably a 1/2" pipe. Who thought up this system, a Victorian.

It is also perverse that we do not directly tax pollution, but add on the cost of green generation to our utility bills.

What do you mean 'turning'

And because of these idiots and super easy to drive cars we now have much safer roads, even allowing for the increased numbers of drivers, the higher average speeds.and cars that are capable of accelerating so much faster than we were used to, not to mention the greater distances traveled. And they all do 50 MPG too. Like anything new, people adjust, and adjust quickly. This does not mean that everyone adjusts, just the vast majority do.
