    They say a picture is worth a thousand words, which means so far you've posted about 1/3rd of a question, which is no excuse for me posting a 1/0th of an answer.

    We walked past Kyoto Honda again today and realised that their BEV charging stations have been installed in front of the secondhand cars that are in front of the hydrogen refuelling station. I guess that definitively shows Honda's position on hydrogen. Today on the road we saw a few current Nissan Leaf BEVs including one that was a taxi, a Tesla, a Nissan Aria BEV and a squillion Toyota, Honda, Lexus, Mitsubishi, etc, hybrids and PHEVs. There's bugger all BEVs in the scheme of things in Japan...

    IMO no problems with 1/2" for the setup you described; 3/4 would merely help pay for your plumber's next os holiday/house/boat/off-road van with no benefit to yourself.

    There was a view expressed in this thread a couple of years back that hydrogen power would soon overrun electric power for cars and other transport. I think I said at the time that view was more than optimistic. Well after a few covid years precluding travel, I'm back in Japan to see my outlaws. At Kyoto Honda's enormous dealership the multi-million dollar hydrogen refuelling station is now islanded in an expanded used vehicle lot. No hydrogen powered car can get near the bowser without moving...

    No one asked or specified how long the 1/2 inch supply pipe is. That might be relevant in a mains gas system with the regulator at the meter end of a long pipe.

    I thought the "boof dabump dabump" noise made as bumper hits, then the first and second wheel goes over is a pretty good detector of an unseen pedestrian; although I guess it could also be an animal.

    Any open bladed fan will not push much air against back pressure, what they will do is become an efficient noise generator. The type of fan shown in the OP will struggle to meet its rated flow volumes even into an open ceiling void. Best to use and inline fan kit like: https://www.fansonline.com.au/ventilation-diy-kits/inline-exhaust-kits.html

    Tesla destination chargers have AFAIK always been able to charge other BEV cars with a suitable cable. Tesla is rolling out a program for Tesla Superchargers to be available to other cars as well. https://www.tesla.com/support/non-tesla-supercharging https://www.carexpert.com.au/car-news/tesla-opens-superchargers-to-other-ev-brands

    As far as I am aware, any car has been able to charge from Tesla chargers with an appropriate cable, so nothing new there. Below is an interesting video that shows the fallacy of direct comparisons of the energy efficiency of ICE versus BEV vehicles here. The tailpipe of an ICE is at the end of a very long, very inefficient and polluting oil extraction and refining process.

    it's certainly suboptimal to have different delivery pressures for hot and cold water.

    1/2 turns are better than 1/4 turns for adjustment. Is your shower head Watermark rated (i.e. flow constricted)? If it is, then that exacerbates the problem if the water delivery is high pressure. A pressure reduction valve on your plumbing might help. We have tank water only with an adjustable pump set to fairly low pressure, 1/2 turn taps and a flow restricted shower head. I turn the hot full on and then add cold water to taste. As the cold gets turned on less hot gets delivered, because...
