Does that actually work? Just because well-off people shop in Waitrose, does that also mean that houses around Waitrose don't include old council estates?
MafellUser · 4 years ago
Most old council estates are privately owned now. Many newer ones are also being sold as shared ownership.
MafellUser commented on Wet/Dry Vacuum Buying Guide (2019)   wet-dry-vac.com/wet-dry-v... · Posted by u/walterbell

When I read the description on HEPA filters, it is alarming advice to me:

  > "[A HEPA Filter] is particularly useful for very fine dust that can be harmful, like asbestos or mold spores [...]"
It is a misconception that you can purchase a vacuum with a HEPA filter and safely pick up materials like asbestos, lead dust, mold. If the seals in the vacuum are not sufficient then you risk throwing around the hazardous materials when you suck them up.

The professional vacuums (such as some manufactured Pullman Holt, Nikro) are tested and certified for these purposes. Please do comprehensive research when dealing with hazardous materials. Consider professional abatement services.

Edit: formatting, disclaimer, typos, precision

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.

I mean, on paper you'd have to walk the tunnel.

In practice, everyone rides their bike, scooter or whatever in the tunnel. And honestly I find it really hard to blame them: sure it's "forbidden", but I'd do the same if I was them (as long as you are not just speeding like a madman)

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.

Battery fanbois choose to ignore why batteries suck so much: they weigh too much, they take up a lot of space, and they take forever to recharge. They see hydrocarbon based fuels are dirty, but you cannot really beat that energy density.
MafellUser · 4 years ago
All good but you know that every single hydrogen car contains a generator that powers an electric motor, right?

If batteries take so much space how comes EVs have FRUNKs while no ICE does? Oh because there's no need for a massive engine block, center diff, etc.

If you want to beat the efficiency, why not have everything nuclear powered?

MafellUser · 4 years ago
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.

How much emissions did that release compared to running a petrol bus?
MafellUser · 4 years ago
Similar to a burning petrol bus.

MafellUser commented on Coinbase does not list securities. End of story   blog.coinbase.com/coinbas... · Posted by u/kgwgk
LatteLazy · 4 years ago
Most Cryptocurrencies do NOT fulfil the definition of a security because there is no underlying "thing". This is why shares (with a company underlying them) are and bonds (with debt and debtors under them) are securities (that and the fact they can be traded) but currencies are NOT. Obviously there are exceptions to that like tokenised stocks. This is also why I would not consider most crypto an investment: there is no source for a reasonable expectation of a return.

In the UK, we just designate certain markets as "regulated" (stocks for instance) and others as not (eg FX). That would avoid this whole nonsense where the SEC etc have to argue that some things ARE securities and others are NOT (if bitcoin is a security then stamps definitely are, do the SEC want to regulate stamps? Or Baseball cards or cars, the examples are pretty endless...).

Watching all of this makes me think regulators either being disingenuous or dumb. I doubt it's the latter. So is this someone just grabbing power for its own sake ("I can get more salary and a better office if we get to regulate crypto)? Or maybe trying to get media coverage to up their personal brand for a political career? Either way, if congress wants the SEC to do this, they should pass such a law, and if they haven't then the SEC should be careful what it sticks it's nose into not least because regulating all of Crypto would be exceedingly difficult and error prone.

Are Forex ETFs considered regulated or unregulated, in your view?
MafellUser commented on Electric Cars – fuel duty and road tax: how to replace £35B annual revenue   carwow.co.uk/blog/how-to-... · Posted by u/phobotics
MafellUser · 4 years ago
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?
