This is where Europe labelling and certification make more sense. L, M , H and H asbestos. Having a HEPA filter is like saying your clothes is 100% polyester, doesn't really say anything useful.
That's false, Blackwall tunnel is completely banned for non-motor traffic. The pedestrian path way is for emergency use only and it's blocked off at both ends. Going down there with a bike is suicidal and also prohibited. During my 7 years commute on the A2 I have never seen a single bicycle down the tunnel.
You sure you're not mistaken for Rotherhithe tunnel?
edit: I see you're referring to Greenwich tunnel. Fair points.
The advantage of batteries is that you can manufacture them into any form and in case of cars, you can just hide them under the floor.
Fine, works well enough in that particular use case.
Does not discredit the what I said at all. There are many other applications where the volume and weight of the battery would make it unfeasible.
You are confusing cells with batteries. A battery is a collection of cells. This difference is rarely important and so few people ever make it. In this context is matters as a EV has many small cells in the battery. You can put those cells anywhere they fit. You can't split an engine up like that. Thus while the battery itself needs more volume and weight than an engine (or at least that is the claim, depending on range desired this might or might not be true), you can put them in empty space where an engine cannot fit.
The software (firmware) is great but the community especially over on Discord leaves a lot to be desired. They have this sanctimonious holier-than-thou attitude towards beginners and anyone dared to question their approach. Check out Thomas Sanladerer's saga with them, it's quite eye-opening.
I use RepRapFirmware for all of my 3D printer builds now. Along with the Duet boards, it's really a very pleasant experience. The documentation is extremely good, the forums are nice, and the codebase is well written.
I also like the "everything is GCode" configuration model. GCode isn't a particularly great language for configuration, but the internal consistency is appreciated. You can play with things in the REPL, and then when you like what you have, commit it to your config file.
I guess the downside is that the Duet boards are more expensive than a Raspberry Pi and an Octopus. On the other hand, not having to maintain a Linux install on your 3D printer is nice. Raspberry Pis are all fun and games until you want to turn the power off. With RRF, you just cut power to the board and you're cleanly shut down. Do that with a Raspberry Pi a few times, and you will be reimaging it.
I also use RRF on a Duet, and have poked through their codebase a number of times.
The codebase is _not_ well written. The fact that it’s written by one person who can’t use commits properly is problematic and leads to long standing unresolved bugs. The documentation is okay but sometimes confusing.
Klipper has much better engineering practices, although their codebase is also a bit messy.

Re: turning off raspberry pis… I’m using a Duet 6hc with the sbc option, eg with a pi, so I don’t think duet gets a point above klipper for that.
They should be considered regulated, because there is some value underlying them (the forex), plus they're traded and offered to unsophisticated investors etc.
A BTC ETF could maybe be the same.
Similarly shares in a farm would be regulated, but farms (or cattle :) ) would not be. Otherwise the SEC ends up regulating all known trade and/or value production...
Completely absence from this are the loss due to lower Benefit in Kind (BIK) for Electric vehicles, and First Year Allowances for EV purchases. Driving an EV means only paying 1-2% per year tax compared to 30-40% for a locally polluting vehicles. First Year allowances mean you claim back 100% of the cost of the EV to offset any taxable income.
These business rates mean owning an EV outright as a normal employee is very dumb. Would you rather pay £300 per month for a PCP on a Zoe, or £150 a month for a Taycan as a company car?
Given that only two cars I've ever owned in 25 years of driving cost more than £300 to buy outright, I can't imagine paying £300 per month for any sort of vehicle.
On top of that, it is ILLEGAL to sell and install dumb EVSEs. Does not apply to third party resales but if you can't find someone to install it, it's a moot point.
