Hopefully none - human body is great at shielding things from EM radiation, and these things are already designed to be extremely resistant to external interferance for obvious reasons.
Considering how nimble e-bikes and e-scooters are, how will the UK police be able to properly catch, aim and target thieves while those heavy backpacks on? What's the chance they hit someone else with their EMP?
This feels like an Onion article or the UK police has too much money and free time on their hands instead of attacking the issue of petty crime from the source: poor education? shit jobs market (especially for migrants)? unaffordable living? etc
DC ("brushed") motors won't be affected by that, especially if controlled with no transistors. See for example how old DC-powered electric railway rolling stock was built, from pre-power electronics era.
Brushless motors have been the norm in e-bikes and e-scooters for a long time. And even modern brushed electric motors in EVs have electronic control via microcontrollers. There's no way you can get maximum power efficiency out of it without software control.
>And no, you don't have brushed motors in modern EVs
Would you be willing eat your words? Plenty of EV motor designs from Continental, ZF and Chinese companies are brushed (or other forms of physical shaft contact with slip rings). Not every EV is BLDC due to the desire to give up on expensive rare earth magnets on budget models.
The part where you go "nuh uh, this won't work on motors that no mass-produced electric bike or scooter ever uses". It probably won't work on horses, either, but that's not what TFA is about.
Do any UK HNers have thoughts on why phone theft is so common there? It’s not really a thing in the US (or hasn’t been for years), so I’m curious why it’s such an issue over there.
That's interesting. But surely stolen ID's could be flagged and blocked from phone networks internationally if there was will to do so? I guess most people wouldn't know what their ID's are to get them blocked in the first place.
All e-scooters and most e-bikes are completely illegal on UK roads. Would be pretty amusing (and dangerous) to see this used on a busy street filled with hundreds of illegal riders.
Are people in the UK no longer panicking about "small boats" anymore? I guess ebikes make sense for a new anxiety focus, given that they are smaller than most other other motorized land transport.
"Police hope the devicewill be harmless to humans and other devices." It's funny when reputable news outlets let silly spelling or grammar problems slip. You'd think they'd have automated away this problem long ago. It makes me sceptical of how much quality investigation and analysis is involved.
All the car, smartphone, insulin pump, and pacemaker owners will surely appreciate this new and exciting EM pulse. And if this device does indeed cause overheating, so will all NHS amalgam dental filling owners and people with implants.
Unfortunately, "the weapon was in development and could be months away from being available, though it is expected to be longer than that", so the public can't enjoy it just yet.
Anyways, what will the criminals do? Will they have to buy petrol scooters again? This will set them back multiple months technologically! Although there are now petrol kick-style stand up scooters, so maybe not.
This sounds like a sketch from Silicon Valley (TV).

That doesn't generate mouse clicks or revenue.

Yikes. Honestly I'm a bit surprised criminals don't already have their own EMP weapons now.
