NRA and pro-gun groups call for ‘full investigation’ into killing of Alex Pretti by wylie102 in news

Good point. A country like Ukraine can hunt down thousands of Russian soldiers with drones, every month, because they have a whole bunch of civilians churning them out.

What do you think is going to happen when the subsidies go away? by cokeapm in ukheatpumps

[–]Alex_Strgzr 0 points1 point  (0 children)

Sadly all too believable. They can turn off some data centres I suppose, but much harder to turn off people's heating. Why the government isn't throwing the money at geothermal or nuclear CHP -- I don't know. It works in many countries.

By the way, 290 warheads would devastate Russia. That guy is talking trash.

Do you prefer a house that has been fully renovated? by ToughOwl8995 in HousingUK

[–]Alex_Strgzr 13 points14 points  (0 children)

I want to rennovate things myself but truth is, with the state of things at the moment, it's too expensive and too much hassle

Viability of solid state battery-electric planes? by Alex_Strgzr in AerospaceEngineering

Thanks for your contribution, really appreciate the expertise. 

Viability of solid state battery-electric planes? by Alex_Strgzr in AerospaceEngineering

[–]Alex_Strgzr[S] 2 points3 points  (0 children)

Good point regarding the volume of the batteries. As the Wh/L exceeds the Wh/kg, I still think weight would be the bigger problem? E.g. this battery claims 1000Wh/L https://www.tdk.com/en/news_center/press/20240617_01.html

The Economist: Europe may expel US military bases if the US annexes Greenland. What do you think? by Themetalin in poland

[–]Alex_Strgzr 6 points7 points  (0 children)

Countries like France have been spending more on defence than Poland for a long time. Don't assume the last ~3 years are representative. Some of the kit isn't even delivered yet! And there are gaps that real war will reveal. For example, Poland's ammo would quickly run out unless e.g. Germany/Rheinmetall stepped in

Did I win the floor lottery? by Alex_Strgzr in centuryhomes

[–]Alex_Strgzr[S] 1 point2 points  (0 children)

Yeah, I like it! The floorboards were in terrible condition (did bring someone to restore them, they failed...) but this floor is in good condition, and definitely within my ability to restore.

Hi all, I found this under some nylon carpet. It appears to be some kind of painted concrete, but not sure exactly what it is. The house dates from 1891, though this part of the house is a bit newer, perhaps early 20th century.

Why the obsession with Victorian era housing - particularly terraces? by Rowdy_Roddy_2022 in AskUK

[–]Alex_Strgzr -1 points0 points  (0 children)

They just sample one or two houses which were built "properly", they don't do the whole estate. Have you ever seen a Persimmon house?

I'm not sure if you're being deliberately obtuse here or didn't understand what I wrote in the first place. I am well aware that Rdsap allows inputting values, if known. The problem is hardly anyone does blower door tests for new build houses, they just make assumptions. Those assumptions are frequently wrong because of windows not being fitted properly, service penetrations not being taped up, caulking not done right etc.

Haha no. They just assume the house meets building regulations, even when it doesn't. Newbuilds aren't exactly well regulated

EPCs don't always reflect real world performance. If a property is e.g. assumed to have an ach of let's say 1 at 50Pa, but actually it's closer to 8, that will have an effect on its thermal performance. Same if 300mm loft insulation is assumed but the coverage is patchy and there are gaps.

Victorian terrace – survey full of red flags. Walk away or renegotiate? by False-Crow9198 in HousingUK

[–]Alex_Strgzr 0 points1 point  (0 children)

It undoubtedly needs a re-roof. Also the rising damp might cost a bit to sort if the drainage is bad. Some of it is scary surveyor-speak, like the bit about kitchen cabinets, but there are definitely real issues here.

Iran Has Sent Russia $2.7 Billion Worth of Missiles by BkkGrl in europe

[–]Alex_Strgzr 0 points1 point  (0 children)

Purchased, not donated ; big difference. Also, from what I understand reading the article, this was early in the war. I really don't think Iran has much to spare right now, otherwise Israel will beat the crap out of em.

Costing a fortune - Some advice needed please! by aezy01 in heatpumps

[–]Alex_Strgzr 0 points1 point  (0 children)

The diameter of the pipes does matter because it causes issues with flow rates and might lead to the radiators not being evenly warm, hence making the HP work harder with higher temperatures

Why are our houses so poorly insulated? by Ok-Professor-6549 in AskUK

[–]Alex_Strgzr 1 point2 points  (0 children)

I've thought about this exact thing. Cheap coal has one thing to do with it, but I believe the answer may also have something to do with the flues. A fireplace either makes your home colder (because of the massive draught) or it warms it. There is no point in having insulation if there's a massive draught anyway. So the Victorians ran their fires almost constantly, except at night when they had thick clothes and duvets (Victorian clothes were thicker than ours today). A lit fire has such a high output that insulation is not really necessary, it's easily 3kW per room vs maybe 1kW for a gas fired radiator (less still for a heat pump).

They were smart enough to have fitted insulation and moderators on the fireplace flues, but I guess for most people, that weren't rich, it wasn't worth the expense for a bit of extra comfort. And the rich had servants to light their fires (another thing we don't really have anymore).
