In the sense that they're not part of the road and may have their own RoW, yes. In the sense that non-ground level infrastructure is commonly used do replace level crossings and seperate cars and others, no.

You don't need to make the infrastructure more dangerous to lower speeds, it only needs to feel that way (narrower RoW with some plants around, more constant small curves, ...). If it would be more dangerous at higher speeds, but speed

Around 60% of people in germany fly less than once a year. A third never flies. I expect that to be similar in other european countries. A lot more people eat meat.

A attiny might not make sense, but you can get something like the PMS150C for around ~5ct, where it makes more sense to use a single MCU than a 555 with all the extra needed BOM Items.

Gas emits less CO2, but when it leaks it's much worse (Methane) so in the United States it's not far off in the normal pipeline network. In most countries we're not close to a penetration of renewables that significantly prof

"Big Industry" matters a lot, but personal transportation is also a large part of emissions. Especially for people that fly intercontinental more than once a decade. It's wrong to assume that you can just convince people to g

You can get 32 bit MCUs for much less (~20ct). But many sensors, USB Hubs, specialized chips have some kind of small processor inside (which is often an 8051 right now) where this could be a good replacement, being low-gate-count, having go

Magnetic cables aren't spec compliant, and for good reason. It's way easier to mess up with the voltage connections and fry the usb c port due to stray metal and a lot more exposed to ESD. You should avoid using them. https:&#x2F

You don't have to license USB, you just need a VID. The USB-IF is planning to enforce some of the labels with trademark law, but (for example) for the Nintendo Switch Nintendo often didn't mention that the connector was USB-C, so

GDPR doesn't require popups, it also allows for programmatic solutions. For some reason (lookin' at you DNT) online advertisement companies, publishers and browser vendors never came together to specify one after GDPR was passed.

We had cars on rails. It doesn't really make sense: The train is much heavier, thus has much lower acceleration and lower max speeds. The mass & area needed per person is also much higher, increasing fares a lot. Terminals & st

The law of diminishing returns has thus far been wrong on battery and renewables. Previous estimates often were wrong due to assuming a slowdown. Not to say it can't or won't happen, but unlikely isn't the word I'd use.

Aside from technical concerns, they're loud as hell during takeoff and landings, making their use inside populated places a bit controversial.

Looking at heating: There are still (admittedly fewer each year) people heating with coal, often with district heating. This results in approx. 1kg of CO2 emissions per kWh of heat (with losses due to the distribution) (gas heating is 200g

But of the places known to have a large share of cycling, none have mandatory helmet laws (at least as far as I know). Thus, it may not be sufficient but it seems necessary. If most cyclists wear helmets, why do you need to mandate it?

No doubt it's greener, but not by an order of magnitude. Looking at the car: A large part of emissions are produced during manufacturing, especially for electrical cars. Driving less helps, but not an order of magnitude. Same with heat

Railroad tracks are pretty flexible, there's no need to bend them separately, you just put them in the sleepers and can fine tune them in there. You can see how much they bend in this video: https://www.youtube.com/watc

In that case you'd probably have a lot of empty trips, dropping the average occupancy of cars below 1. I think it's unlikely we'll see a lot of 2-4 person ride sharing (dislike of strangers, longer trip times due to needing t

Germany never went all-in on electricity like e.g. France did, even while building NPPs. What is now an issue for germany is the move away from domestic or easily replaceable fossil fuels like coal or oil in favour of gas.

by danhor 4y ago
The only issue with that point is that the share of natural gas in the electricity mix hasn't meaningfully increased in germany over the last decades.
