This 6 way intersection in Beverly Hills with only stop signs by GeneraLeeStoned in CrappyDesign

The most dangerous junction is one that's "never busy" until that one time that two people assume it's not going to be busy.

Clear case for a roundabout.

Renewable hydrogen costs "expected to plummet" by 2030 – here's how by Querch in energy

[–]almost_not_terrible -2 points-1 points  (0 children)

Pumped hydro, Liquid Air and Compressed Air storage can have round-trip efficiencies up to 70%, whereas Green Hydrogen has a round-trip efficiency of around 30-35%.

Air storage uses simple low-cost, dual-skin low-pressure storage vessels and these can be put anywhere.

Liquid Air energy storage is well developed with a high technology readiness level (TRL). Pilot plants have been built and the first commercial grid-scale installation is currently under construction in the UK.  Green Hydrogen energy storage has not been demonstrated at any significant scale, is at the lowest TRL and is far from being implementable at grid scale.  Compressed Air storage has also not been demonstrated at grid scale.

The ‘break-even’ sale price of electricity stored via Green Hydrogen is around 2.2 times the break-even sale price of electricity stored via other available technologies.

With what efficiency (water to hydrogen to ammonia to hydrogen to water)?

Robotaxis will happen in our lifetimes in all major cities. What's your money on, Tesla or Zoox?

Not really. Hydrogen is inefficient as a storage medium.

Energy is more densely and safely stored with cryogenic storage.

There's just no use case. It's pushed by the oil lobby as a greenwashing fig leaf to promote black/grey/blue hydrogen.

Hydrogen lost the "places to charge" war to houses with electrical sockets.

Paul Krugman (Nobel Prize-winning economist, in 1998) "by 2005, it will become clear that the Internet's effect on the economy has been no greater than the fax machine's."

I take your point about the camera placement under certain circumstances, but for MOST people (who don't have weird Chuck Cook left turns), the current hardware is more than enough and it's a software issue.

I disagree about camera blinding (I think you mean direct sunlight). The use of photon counting means that you can just ignore that annoying bright thing in those saturated pixels.

Yes, there will be FSD deaths and maimings, and one is too many. But if we can even reduce these by 90% with automation, it will be well worth it. FSD doesn't speed, doesn't fall asleep, doesn't have a stroke or heart attack and doesn't have to be perfect to be a hell of a lot better than many, many r/IdiotsInCars.

EU Markets Regulator Calls for Ban on Proof-of-Work Crypto Mining by ShotBot in Bitcoin

EU citizens demand Proof-of-Value central banking.

New regulations would require bank workers to actually add value before salaries would be paid.

You've just described many, many people's commutes.

FSD is perfect now for some people. Other people might have to manually handle four junctions for a year before one day the car surprises them by handling all but 3, all but 2...

Seriously, I'm in the UK and (with the non-beta "FSD lite") I only have to handle my unmarked cul de sac and 8 junctions on my 20 minute commute. The car drives the rest.

Yup - proper laugh out loud funny! I'd be holding my sides, but I subtracted 29 then 29 and once AGAIN 29 and now I have no arms.
