2:55 high heat isn't the only option, there are several solvents for ethylene vinyl acetate which seems to be what holds the panel together once the frame is removed so mechanical separation seems entirely feasible. To be reused the component materials need to be melted anyway & the metals will separate from the silicon as they melt so can simply be skimmed from the melting pot as they surface or sink. The melting points are 962, 1084 & 1414 °C for silver, copper & silicon respectively which is a sufficiently broad range to largely separate them though there may be some alloying.

 @naekosl3059 don't just blindly repeat propaganda, think first!

@MoDa87 there's the problem, people voting for right-wing governments which will always shift money away from regular people & towards the already-rich & greedy megacorporations. There's plenty of money around, it's just that we won't see it till we learn to vote in our own best interests.

@jimmiller5600 in most countries public utilities are public, or were until Neoliberalism was inflicted on us in the 1980s raising prices & reducing service. There are exceptions, all of which seem to feature corruption at the heart of government.

@veedrac in most countries grid infrastructure is paid for through general taxation because it's a public utility & therefore State-owned. USA is an outlier.

@apostolakisl while power companies were establishing themselves in the USA there were routinely 2 though rarely more than 4 networks running along each street. Most countries disallowed the mess & regulated standards & created public utilities for distribution, often for generation too. USA is weird.

6:52 I didn't know Shell made solar panels at all but BP had essentially stopped making them years before this date, they were good panels though, well made & reliable, you can still see them on top of road signs & sometimes traffic light control boxes across the UK, sometimes accompanied by a small wind turbine mounted on the same pole. It definitely feels like lucrative Government contracts ran out & they had to charge market prices so the sale price went down to eye-watering from astronomical & that didn't suit shareholders.

@Chris_at_Home I know quite a few people who live in round things, domes, teepees, repurposed tanks etc & they all love them, apparently they're good for your mental state.

@rrs_13 I'm curious, how do you use hydrogen as an energy storage medium? Do you heat it up? Use it as a dielectric or electrolyte? Do you spin it? How does it work? I'm used to the chemical reaction of hydrogen with oxygen to make water being considered an energy source. (Other reactions are available).

I'm surprised at this, is the problem with solar thermal the price of the control gear & a tank with an extra coil? I'm not in the market yet but from what I've seen the systems are overly complicated. Solar thermal should be good because it can accept more energy than the 22% current maximum of PV.

@aidanmatthewgalea7761 the tech described in this video has been in production something over 130 years, with recent updates which are also in production.

@timothyjohnson6055 that's "Passivhaus". Matt did run through his thoughts about it a while back though I forget his conclusions, it will be in his back catalogue somewhere.

Concorde getting up to speed over Penzance (Cornwall, UK) was an annoyance, no more. Over land it flew below Mach 1 so no sonic boom, this is a requirement for all aircraft in almost all countries. Booms at low altitude like military jets would be more problematic but happen now anyway & aren't covered by this video.

the panel flipper at 14:22 had me cringing, the chap is inside it as it closes! Reminded me of the trash compacter the heroes get trapped in in Star Wars.

@gaberoo9099 Bimble Solar may have your answers, they do cheap panels (rejected for wrong colour frames etc) & most of the other parts you need. They're in the UK, I think near Lewes but they ship for a fair price so I've only done mail-order with them.

@janami-dharmam thank you, I've edited it

@apostolakisl there are many instances of free markets of regulated utilities, they're not mutually exclusive.

@samiktiri "magic bracelets" have been powering wristwatches for about 50 years now. They're not super reliable but that's engineering not science so if the makers chose they could fix them.

I shall be putting a small wind turbine on my RV to compensate for the solar panels doing virtually nothing for a month in mid-winter. I figure it will be cheaper than replacing the batteries every year.

is that the video that's linked at the end?

Nickel & Iron are the 2 most common metals in the solar system, unfortunately nickel isn't so common on Earth. (Asteroid mining perhaps?) I like NiFe, they're tough, reliable & easily recycled, but weight/Watt-hour they're nothing like as good as Li-ion. They're still used as propulsion batteries in submarines & used to be used in forklifts & local-delivery vehicles like milkfloats though lead-acid took over decades ago & now delivery vehicles at least are going over to Li-ion.

slingshoting asteroids into low Earth orbit then just nudging them down from there seems cheap & simple, plus would collect some of the millions of pieces of shrapnel in orbit.

You don't mention VoltStorage, a German company that seems to be making these on a domestic scale?

@wirelesmike73 as I understand it it's the other way round – the hardware wears out eventually but the fluid is fine.

The Victorians in parts of Britain were running street lighting on sewer gas. More recently, the main bus fleet in Bristol, England has been running on sewer gas. For many years there have been gas turbines running on gasses from landfill which supply electricity locally.

Poop is one of many hydrocarbons which can be fed into oil refineries. You can also feed in food waste - undigested poop.

@MaththeCanadian yet another ill-informed naysayer! Stop reading oil-company & conspiracy-theorist propaganda & find out what's going on in the real world.

they're in widespread use & even available on the domestic market.

@grizzlythegrey9464 I would also like to see bio-gas & bio-Diesel compared

@jeffk464 wood is certainly a better insulator than metal but it's not brilliant, you need proper insulation over it.

@apostolakisl net metering is offered because it reduces the need for centralized peak-load generation, that's why offered prices are different at different times of day.

@geoffreychadwick9229 A limitation of plug-in charging is that it's plugged in – it has to be operable by a stereotypical "little old lady" so cannot be heavy. This is not the case with charging pads, they are fixed, if necessary they can be placed with a forklift.

As you say, prices vary regionally, for instance the difference in price in the UK isn't 20% it's nearer 400%

@pepermintpilot1694 quite probably PR, the lead-acid industry pulled some nasty stunts in the late 1800s/early 1900s with the intention of killing NiFe & carried on till NiFe died as a popular tech in the 1960s/'70s. This had the effect of killing off every other tech except for very niche markets & small batteries. NiFe are still used in submarines because potash fumes aren't hazardous & there's still a few century-old battery sets where the industry using them has survived that long. They're currently made in Ukraine & sold in Britain by Bimble Solar but they're expensive & similar size/weight to lead-acid & only in a very limited range of sizes (Bimble sells 2 sizes).

@lordofhnajuty that's good but we haven't got 20 years, we should have done it 20 years ago!

@toepunch001 seriously?!? someone is deliberately vapourizing uranium & plutonium? #WTF!

@orionbetelgeuse1937 no, mixing ground-up batteries into concrete makes a structurally-compromised material, look at the chemistry, sand (& therefore glass) is already a component of concrete & has been at least since Roman times, it's safe.
1
@Crunch_dGH Tesla Powerwall is already 2nd-life Nissan Leaf batteries & always has been. Solar panels too are 100% recyclable right now (chisel off the metals for re-use & smash the rest into building sand), it's the economics that's in the way, particularly if you want to separate out the silicon for re-crystallization.

@P Kudsk if you're going to be a naysayer please at least have the decency to post some current & accurate figures.

How useful would these be for storage inside a container ship or cruise liner?

I would like to see how you keep all your data isolated from the internet so 1) it can't be hacked or virused & 2) the data isn't used to hack elections. Especially the home automation (which I would like to see lots of techy info about).
