It's really astonishing how well engineered these panels must be to cope with such extremes of temperature and the expansion / contraction rates of the different materials.
Satellites use solar panels and they survive pretty hostile conditions.

I really want to know under what circumstance any trombone repair is an emergency!😂......an emergency trombone repair......

Initial cost. Almost everyone at some stage is going to have to finance a huge lump of money they would never have had to.
Possible long term costs as batteries fail and then the car becomes a useless lump of steel and plastic.
None of these questions have been answered in a comprehensive way, let alone ones I havnt thought of.
Equally, you have to concede, one of the problems is that ICE cars work SO well for people, that's actually part of the problem.
People only like 'selective' change. If it boosts their ego / perceived standing in life, they're all for it. Otherwise, they're dyed in the wool traditionalists.
I see it's the same old tropes...
EV batteries need replacing after 5-10 years. No they don't, they're guaranteed for 8 years. And they gradually decline. They don't get to 10 years old and explode /suddenly die.
That kind of proves my point - EVs are sold on their environmental credentials; when really we're just exchanging one unsustainable evil for another - while at the same time lining the pockets of the man and screwing our own future.Mining. Because oil drilling never hurt anyone.
Given how much energy it takes to accelerate / push through the air a large, 2 ton metal box / that really doesn't sound correct... and indeed according to this source (near the bottom and full disclosure I've only skimmed it as I have the attention span of a potato) it isn't:If we all had EVs then UK power consumption would go up BY OVER 1%!! Oh, the humanity...
Another of the sensitivities – missed by the newspaper headline writers – is called “High EV”, and tests the impact of even faster and wider adoption of the technology. It sees all 35m cars in the UK becoming electric in 2050, with a limited spread of autonomous vehicles and an unmanaged grid, where most consumers charge up at similar times.
In this worst-case scenario, peak EV electricity demand could reach 30GW, far more than the 18GW highlighted in the press. This is equivalent to half of current peak demand on the GB grid.
How does that work for those of us who typically spend a grand or less on a car? What sort of mileage / battery degradation are we talking at that price point? How long is that vehicle's viable service life compared to an IC equivalent? What about the energy and material costs of production and disposal?For instance the huge lump of money is not needed, we can buy a second hand Leaf for £6,000.
Because "veteran cars" are basic, easily user-serviceable mechanical vehicles with a raft of low-cost spares availability.People run model T's and other veteran cars, so why would electric cars become useless.
That's a bizarre analogy though, is it not? It's not a case of "electric bad, mechanical good" across all possible products and markets, it's a case of suitabilty and viability for the application in hand.And yet I bet they all accepted at some point an electric watch...........and many other items that went from mechanical to electric.
I think a slow cooker should be manageable. I think they are about 100-200 watts. Although you'd probably be advised to cook highly calorific stews as you'd be quite hungry after all those hours pedalling.Human power is great for perambulating yourself around the countryside on a two-wheeled escape machine, although I have my doubts about my personal ability to power my cooker.
I think the biggest problem facing any alternative power sources is that too many people seem to believe we can just carry on doing what we do now because it suits their current work or lifestyles.
Unless the majority embrace the need to change we'll probably end up in a cul-de-sac of worn out supply side and inadequate variety of consumption methods to spread the load.
Less car sized vehicles is the on the roads is probably the only way out of the current hole but the least likely to happen.
Don’t confuse people ‘not liking change’ with people ‘seeing the emperor is naked’.
Imagine the UK cars changed to ev’s. 30 million ev’s needing 12 kWh per day (about the same usage as a 4 bed house) to charge. 360 million kWh per day, 360 mWh, .36 gWh, over 1% of the UK daily production of 27 gWh. Are we going to double the number of hydro electric plants, or double the number of coal plants, to supply this?
