I like being alive and not being rammed by a 200kg combination of e-bike + human at speeds higher than 25kmh while riding my bike to work.

Said literally nobody. 15mph is plenty fast for getting around :) The more important part is making biking more attractive by building better infrastructure for it and actively restricting car traffic by slowing it down or diverting it out of cities.

I think they will simply get burned as they are not designed for radiation levels 2x or even 10x of normal sunlight. (10x would be a huuuge lens) The cells in the paper are actually fucking tiny, the lenses apparently create an area with 1000x the energy density as normal sunlight, so these cells are just completely different from normal PV cells. If you focused that much energy on a normal PV panel it would just melt or evaporate.

The single cell–lens unit uses a solar cell with a chip area of 885 × 685 μm2 and an active area of 585 × 585 μm2

So the actual cell is roughly 0.6mm by 0.6mm

“In terms of our consultation, almost 7,000 responded – and seven out of 10 support our bold plans to regenerate this iconic street

70% is hardly "north korean levels" That would be more like 99% :D

My friend was hyped a few months ago about the fall of the regime. I had to try really hard not to just immediately send her this meme.

I clicked on a few but admittedly gave up too quickly. The paper had the same picture but fairly low resolution. This article had a better one: https://www.pv-magazine.com/2025/06/05/fraunhofer-ise-unveils-micro-cpv-module-with-cost-reducing-design/

I wonder when this was taken, because there is not a single airplane in this picture i think. Maybe before it opened? Usually you always have a couple planes standing around getting boarded or taxiing like in this picture from wikipedia.

It got like 40 Millions passengers in 2023 so it should be very busy.

Can they sell the german one too please? I want their filth out of Europe.

These types of articles are always cool sounding but they never have any actual images of the design in question. Sad science noises.

I was happy to see Anubis have a place in the canvas and quite a big one too :)

Not at all no. This used to be a sort of self regulating system. Peoples ability to go fast with muscles alone usually goes away around the same point where their cognitive abilities become a hazard to the rest of traffic. The difference is that most young people could easily go 18mph or more while old people wouldnt even get past 10 without e-bikes. Basically e-bikes allow people to go beyond their limits. While that sounds cool, in this case it isnt.

Yeah this proposal is reasonable. I wouldnt want to share my bikepath with old people driving more than 25kmh. They just dont have the reaction time to safely drive at speeds like that and even that is actually waaay to fast for the oldest. If you wanna go faster, use your muscles and/or drive on the road.

Organicmaps had support for it, so i dont see why it would have disappeared after the fork. I have no idea how android auto even works tho so idk lol

Heh, nice one 👏

This is so tame tho

I dont want to relativize violence too much, but with these kinds of incidents in a political context, its always best to think about it in a "statistics" sort of way. Just in the short time of these unrests there have probably been 10 incidents like this with Spanish born perpetrators that got zero press coverage. People give individual events like this waaay too much sway over their thinking. Its bad that it happened, but its also not out of the ordinary whatsoever.

Quite a bit of sun radiation gets through the panels i believe, so it wont be completely dark below. Im sure the types of flora to be found will change a lot tho.

Well no, those things wouldnt happen, but yes the response is much too muted. Realistically the Trump admins response will be "Well what were they doing there in the terrorist country in the first place" in typical victim blaming fashion.

It does say "BIOS Setup Utility" at the top tho...
