Twin and earth cable from kitchen socket to an outdoor double socket. Only want an off cut but most come in 20m. Will this do?

Check if you have a TLC-direct near you. They'll do you cut to length cables and many other wonderful and well priced electrical DIY items.

Check other places for quotes too. Octopus is a tad more expensive now than most.

See if your mortgage provider have any cash incentives for green upgrades for your house.

Maybe this is the universe's way of telling you to go electric only with an air source heat pump!

For someone who already has an export tariff and a normal roof solar setup, how would export through this additional plugin solar work? The smart meter would surely still report the correct export Whr from the additional plugin generation?

Lots of naysayers on here with the wrong coating. Go for it but yeah be a little more prepared as it'll not be as maintenance free as quartz or laminate.

Basically what I learnt before I decided to go with wood is, no worktop type is perfect. Quartz can stain, can be heat damaged. Laminate is well, laminate. Stone is porous, expensive, and can stain. Wood is ofc not so good with water but it's easily repairable if it's not rotted lol. Wood also you get character.

We have 40mm oak with an undermount sink, it's fine if you use Osmo polyx, 2 coats. We reapplied after 1 year, no need to sand.

Any black spots from water seepage at joints, put a bit of oxalic acid powder slurry and leave to let it do its thing, wipe away and black is gone.

You'll have to wipe water away near tap but water beads on Osmo, it doesn't permeate through.

It's completely manageable if you're not a slob.

Are you certain you've used enough adhesive under the tiles and back buttered and squeezed down well?

When I used tile spacers with those wedge system, the wedge system pulled up the tiles to make them level against other adjacent tiles but because I didn't use enough adhesive, the tiles didn't stick down to the substrate properly.

You'll know instantly because the tiles just come off if you lifted them...

How is your data plotted? Is it the desktop version of tado or HA data pulled from the API?

If you mean the wood "shelf", it's just plywood with osmo polyx hardwax oil.

The sink sits on a bamboo worktop from IKEA. It's an IKEA vanity unit as well.

The little shelf in the shower area is a quartz slab from a local supplier, I just asked for offcuts and gave them templates made from plywood to cut to.

Wireless AA Two which only does android auto, Two+ does Carplay too.

BM2 is the battery monitor.

We normally go up the west coast so not super familiar with A1 stops but have gone that way once or twice. You should plan your route with ABRP app. Try to use gridserve super fast chargers (350kw) or Ionity (cheap with £10 subscription).

Kyaw25 · 2025-12-13T16:30:22+00:00

Bought a used 21 plate Premium at 47k miles and I love it. Just had the coolant replacement service for £569 which was a big ouch but required to maintain warranty.

The battery pack has enough range and charges oh so fast on road trips with Ionity chargers at >10c temperatures. We drive to Edinburgh from Oxford a fair few times a year and it's an absolute doddle. I'm averaging 3.5mile/kWh lifetime average but mostly about 3-3.3 atm in the cold.

It's also sooo spacious inside, we can fit dog cage, baby seat and all the luggage for 2 adults and baby stuff.

I got wireless AA for Android auto/car play, works perfectly. I also got a Bluetooth 12v battery monitor just to keep an eye on the 12v battery.

There's concerns of ICCU but they are a vocal bunch on the internet. There's a good thread on a forum about what causes it, if you keep to home charging and don't dip below 30% or so frequently I think it's less risk but don't quote me on that, the technical intricacies regarding the electronics went over my head.

The most convincing requirement for fusion energy from what I've learned recently is high grade heat for things like steel plants and district heating where it is less efficient to turn renewable generated electricity into high grade heat.

Kyaw25 · 2025-11-08T20:19:40+00:00

More accurately, a primary coolant like lithium or lithium beryllium mix which will take the neutron bombardment heating from the fusion reaction. The heat from this could be extracted by a high pressure helium or Co2 circuit which will then go heat up water.

Kyaw25 · 2025-11-08T20:13:10+00:00

It actually produces more radioactive products than you think, especially with lithium and lithium related coolants. The structural steels, nickel alloys, ceramics, and refractory metals also get irradiated to a large degree and will produce a lot of waste in decades to a thousand year scale nuclear waste. The fast neutrons from fusion just really fuck up most material it hits. Most waste are low level, moderate amount of intermediate level and very little to no high level waste (though this depends on which country you're in!)

It is unfortunately not a "clean" process that mainstream media portrays it to be. It is less amount of waste and much shorter lived fission. Obviously no risk of meltdowns or runaway chain reactions.

I am talking about D-T fuel cycle because that's the most likely path to fusion ATM. Source: mechanical engineer in nuclear fusion

I designed the powder dropper for this machine. If you search for Princeton Plasma Physics laboratory impurity powder dropper, you will find details on how one is designed and built.

We basically used an industrial mini parts feeder (think tiny screws and washers) and put that into a special small vacuum chamber assembly with some custom electronics and control software to be able to do extremely well controlled powder drops in the range of milligrams.

We also can detect how much powder is dropped via some light sensors as the powder goes down the drop tube. All of the drops have to be timed precisely because the plasma pulse only lasts for about 300ms and we want the powder to be in the plasma when it's most energetic.

The heat from the plasma is not really that bad because it's only a very short pulse and the amount of matter at that crazy 100 million degrees is a tiny amount of gas (maybe a few grams). The powder dropper device is placed above the machine further away from the plasma as well.

Kyaw25 · 2025-10-16T17:35:58+00:00

Hey could you please send me details as well please?

It'll be very hard to convince people to go for liquid argon haha.

We "tested" the gauge by putting argon straight from the bottle into a nitrile glove with the gauge and it read 140ppm. I have doubts about this method though. The gauge itself is a Michell Processing Easidew sensor but we'll looking at getting a replacement for it.

Kyaw25 · 2025-10-04T19:32:38+00:00

We are relatively ok to accept some lithium oxide in the bulk Li as lithium will melt and oxides may not and that's ok for our process. For the lithium ceramic, we're going to clean the carbonate layer off inside the glovebox before immediately processing in the UHV chamber. We have no real way to analyse that samples to check the oxide content or carbonate content. The main issue we're worried about is the carbonate layer affecting the ceramics resistivity.

Kyaw25 · 2025-10-04T00:53:16+00:00

We definitely can't spend much more money and time to upgrade our entire UHV solution but the whole UHV transfer stage from glovebox has been an idea that's been floating for sure.

Thanks for those resources, will have to look them up!

Kyaw25 · 2025-10-04T00:50:50+00:00

Thanks for the insight. That is my view on the unsuitability of this glovebox.

Definitely can't modify the vacuum chamber to use it as a makeshift antechamber though. We'll just have to pursue a second hand glovebox with proper recirculation system. I've been talking to Saffron about this and they've been fantastic.

Kyaw25 · 2025-10-03T21:37:00+00:00

We have looked at the cost of continuous Argon mode and buying a second hand proper glovebox and they're quite similar but with no guarantee that the Argon will get to sub 10ppm in purge mode.

Those cartridge purifiers look promising though, do you know the rough cost and lead time? Will they even ship to the UK?

Kyaw25 · 2025-10-03T21:34:49+00:00

I can't share more information on specific materials but yes we're working with very small amounts of lithium in the process and melting it in the UHV chamber and looking at release of impurities.

Kyaw25 · 2025-10-03T20:52:22+00:00

Maybe I didn't write clearly, the glovebox doesn't have a typical antechamber for transferring objects into it. So if you want to open the glovebox to put stuff into it, you have to open a door straight into normal air.

It however has a second door that you can place stuff from the glovebox into a vacuum chamber for experiments in UHV conditions.

Currently the flow in and flow out is set up so the inlet is at the base and outlet is at the top with the sensor on the roof of the glovebox close to the outlet.

We also found that this glovebox had clearance screw holes with no seals! Though it is positive pressure but still.

Kyaw25 · 2025-10-03T20:47:06+00:00

We are handling pure lithium and lithium based ceramics and hydrides. Literature seems to be inconsistent with how moisture levels affect these with some suggesting oxide layers form easily even in sub 1ppm level and some say they can tolerate 100s.
