Kinetic energy is exactly what’s harvested, which is why modern wind turbines are not far off the theoretical limit of the amount of energy that can be extracted. (Betz’s law)

By taking energy from wind, you slow it down. Slow it down too much, and it can’t get out of the way in time for new air.

Those regulations exist, enforcement is the problem. Fatbikes are the main culprit here. They are sold within legal limits, but it’s incredibly easy to just remove the software limits and/or flash custom firmware.

Police does regular checks, but people tend to quickly turn the limit back on when they see an officer.

The upside is that they can slap down 3D printers in all sorts of sheds and make parts decentralised. If they can keep up with demand it’s also a logistics win.

That would imply en existence of display/usb outputs…

We’re essentially talking a bunch of embedded devices talking to each other. You can give them all the dns entries you want, but if they (or the programming environment) don’t support DNS lookup you might as well put your dns server in excel.

For that to work industrial devices have to support DNS in the first place…

That was about the lock in part. Most of the mavic footage I’ve seen seems to be digital at least, though I recall something about them changing the RF frequencies constantly to avoid jamming.

I highly doubt the mavics used in Ukraine still run the stock firmware

The Netherlands already has quite strict rules around e-bikes and is looking into tightening things even more as there’s a rise in e-bike accidents. Currently it’s no support above 25km/h, no throttle, <250W.

It’s the exact same in the Netherlands. The pedal assist is capped at that speed, but nothing stops you from powering though that and going faster. Not that it makes any sense to do so for the average daily office commuter.

When we get resumes, applicants that don’t have some variation of firstname.lastname@… as their email tend to go on the bottom of the pile.

I don’t think I’ve ever seen one of those “American style” ground units in Europe. They all look like the one in the picture and are predominantly wall or roof mounted.

What they do here for (a good amount of) home car chargers is read out the electricity meter using their serial port and dynamically adjust the charge current to never take more than those 3x25A.
