I'm surprised at this - seems bizarre that it's a 'great product' but isn't commercially viable in any way? As an aside, I really can't understand why people are so enthusiastic about Dyson products - I find them to be poor to use and poor performers. My gf has a dyson vacuum cleaner (a v6, I think), and it's terrible. Battery life is minimal, the suction is poor compared to anything I've used in the past, all the no…

When moving to the US we decided to not skimp out on the vacuum and went with a Dyson Ball Animal 2 (an almost $500). It's one of the worst vacuums I've ever used. It's clunky, has poor suction and is a pain in the ass to empty/clean. I don't know if it's because it's an upright or if it's just a bad vacuum. Every canister style vacuum I've used in the past have been a pleasure to use compared to the Dyson. I even pr…

You probably should of did a little bit of research an got a Miele.

There was this TED talk once about shaking your hands twice to only need one towel. I've been doing it ever since and an Airblade will dry my hands in 10 seconds.

It's 12 times and leaves quite a mess

That's what the sink is for.

Specifically, as @m-i-l noted ( https://news.ycombinator.com/item?id=20745170 ): > One of the "selling points" of the Sinclair C5 was that its electric motor was built by Hoover and would be serviced at the existing network of vacuum cleaner service centres ---- But generally, microcars are fun.

That rocket boat looks like a swimmer skewer.

Why do you imagine that normal hands dryers are wet? The original Dyson airblades? Sure. Those are gross. Normal air dryers don’t have anywhere to store water, and if somehow you got water inside, it would rapidly dry itself out from normal use.

I had to read all of 4 sentences to see that this does not say that air dryers are growing bacteria. In fact it says the opposite, that there was very little bacteria in the nozzles. There is bacteria in the air and the dryers are sucking it in and pushing it onto hands being dried.

> I don't get why this states "25 seconds". Do people have hands made from sponge? I don’t know why 25 seconds is hard to believe. That’s the manufacturer’s claim. I’d imagine if anything their claim is optimistic and the 60 seconds people claim is more realistic. If you have washed your hands properly, you’ll have several milliliters of water spread across the surface. Slow blowing warm air isn’t going to dry that o…

This is a really bizarre statement. You throw some numbers up and then say “obviously it should work how I said”. But it’s not obvious at all. Those numbers don’t intuitively tell me that it should my hands in 5 seconds. Indeed my intuition (and that manufacturer’s specs) says that’s wildly inaccurate.

I’m really confused by your “1 meter away” claim. At a meter away you’re basically just waiting for ambient air to dry your hands. The fact that they measure decibels a meter away doesn’t mean that’s where your hands should be.

Are you sure BO are in the same class as Dyson ? BO seemed to me a very niche luxury brand, Dyson is way more mainstream. Both have different values.

I believe B & O just did the enclosures and used other manufacturers parts so you basically bought a Philips TV in another jacket.

Yep. We took a B&O VHS machine in to be fixed. Guy who specialized in fixing them, had a pile of pre-shelled guts he just fitted into the pretty B&O case.

Shocked! This is akin to if a bicycle company tried to build cars, thinking their engineers can simply shift from bicycles to cars...

The Wright Brothers had a bicycle company and then invented the airplane[1]. They didn't just make airplanes, they invented them. I have no stake in the Dyson car, but there are other reasons that it didn't work out. [1]: https://airandspace.si.edu/exhibitions/wright-brothers/onlin...

Though the Wright Bros weren't competing with existing entrenched aircraft manufacturers in the way Dyson would be competing with Tesla et al.

He was very pro-Brexit, then left the country and moved to Singapore.

And he moved the company to Singapore.

A lot of the more hard core brexiters would like to make the UK like Singapore.

My statement is this: I've used a sub-2kW blower that could dry hands in below 10 seconds, was loud but not painful, and if you somehow made it portable, it could double as a leaf blower in a pinch. 1 meter from the nozzle the stream was still powerful enough to dry hands faster than ambient air. So the numbers people throw around this thread are weird, they imply unrealisticly wet hands, or ridiculously inefficient dryers.
