Dyson backs Britain plc with $2.5bn AI and robotics investment Britain's most successful engineer Sir James Dyson is taking on Google and Facebook with a $2.5bn investment to turn the former RAF base at Hullavington near Malmesbury into a research campus for robotics, AI, and other advanced technology, including batteries and vision systems. The size of the planned facility dwarfs the …
constant 240v across europe
Defined as a constant 230v -6%/+10% across the EU. Used to be 230 +/- 6%, but the UK was 240 +/- 6% and that could take it outside the EU range. Changing the voltage was far too complicated, so in a wonderful bit of completely ineffective EU standardisation they redefined the upper tolerance to be +10% and the UK redefined it's lower tolerance to be -10%. Now everyone can be between 216 and 252v, and we're still all at the EU "standard" of 230v.
i assume the issue is that the same device connected to feeble euro voltage will use less power than when connected to heroic uk voltage, given the situation of a simple load P = V*V / R
dyson are free to test at euro voltage, that's the point of eu wide standards, seems like a level playing field to me
if dyson chooses to make a device that consumes more power at euro voltage that's dyson's problem, can't blame the germans for it
But the EU's energy labelling regulations decree that voltage
I think you mean wattage. The voltage is set by the electricity generators and reduced by them when demand is high, so specifying it is meaningless for a mains powered device.
Also, as any fule kno, power = watts * time, so limiting the input wattage is also pretty futile because limiting it just makes the run time longer. The only realistic standard for, say, a vacuum cleaner would be to set a limit on the number of kilowatt hours used to clean a specified area of a standard floor covering. But try implementing that sort of standard for all mains powered domestic appliances and bureaucracy will think all its Xmases have come at once, so lets not go there.
Wow, three downvotes against basic physics.
The Watt is a measure of power.
Power (in watts) is defined as energy use (SI unit the Joule) per unit of time (SI unit the Second).
One watt is defined as 1 joule per second.
watts*time is not a measure of power, it's a measure of energy.
I personally don't like cyclonic, bag free vacuum cleaners, I don't think cyclonic effects really work well at less than about wheely bin sized receptacle vacs with a small diesel engine to run it.
However, Dyson has successfully spawned a growing market segment in vac's that others are only too happy to copy, not to mention all the other items on his books and he certainly knows how to sell. I also like his ideas about bringing back training instead of relying on University and college taught technicians who may have not been taught to engineer the way his company needs them to.
Considering he has 2.5 billion reasons to think he knows what he is talking about with his new campus, he probably does, I wish him luck and hope he makes the old base into a world leading Technology centre.
"Several of Dyson's hallmark products are more energy efficient because they use more power for a shorter period than conventional products on the market, some of which are made by German rivals including Bosch and Siemens."
This has indeed been my experience.
The Dyson my wife bought died after 18 months. The German-made appliance I bought (that she wanted to replace with said Dyson) is still kicking after 13 years.
The Dyson was definitely using power for a much shorter period than the German thing.
