I was responding to the point about using AC all year to remove humidity. The thermodynamics works like this: The air inside your house is more humid than the air outside; warm air at the same pressure holds more moisture than cold air. Whe

Passive houses typically need almost no heating so it doesn't matter how the heat it delivered.

Nighttime cooling only works if you have a big thermal mass inside the insulation envelope to cool down to store your 'coolth' in. In general the problem with lightweight stick frame construction is that it is too quick to respond

You don't need AC to remove humidity. MVHR removes it and dumps it into the drains when the warm outgoing air goes through the air to air heat exchanger to warm up the incoming air.

Roads have only been a public good since 1888 in the UK. Before this it was common to pay a toll to be able to use a road. https://en.wikipedia.org/wiki/Toll_roads_in_Great_Britain

Exactly. Successive governments in the UK waste vast amounts on money on stuff like health service reform, which get unpicked by the next government. It is deeply stupid the amount of money we in the UK spent on brand new nursery schools th

The specific Rolls Royce engines used on the A380 were developed specially and were a leap in efficiency at the time the aircraft was introduced. The Dreamliner and A350 use engines that are of the same technological level, but the airframe

Rolls Royce had to design special extra large engines for the A380. Because of the large diameter of the fan they had to use clever blade geometry to overcome problems with supersonic airflow at the ends of the fan blades. So I'm guess

But no-one believed it. At the time there was a protest of well over 1M people in London against the war. Which is huge, between 1.5% and 3.3% of the entire population of Britain. My work actually gave us the day off to go to it.

Also there is no punitive damages in U.K. law. So what’s the worst that could happen? Would you put them back in the position they would have been had the contract not existed, so give the cards back plus a contribution towards depreciation

Trams are expensive because of all the pipes and cables under the street that have to be moved. Also a funicular train is driverless and unpowered, more like big elevator car than a train.

When I studied history, quite a few British schools didn’t teach history as a timeline it was more like a series of case studies, which were designed to help you understand primacy of sources and how to analyse information. I studied Histor

There was a post about energy use recently. C, C++, Rust and Swift were often sharing the top 4 slots for various efficiency metrics. I would guess that energy efficiency is also a good metric for execution speed as well. Concurrency suppor

I can't find a source that doesn't involve doing a lot of maths but I think a significant proportion of the fuel used by Concorde was taxiing, takeoff and climb out. In supercruise Concorde used less fuel than an 80's era 747
