You wouldn't need a modern detector for that source. Any basic Geiger counter would pick it up cruising down the road at a reasonable speed.

You sure about that? There are pumps commercially available That can give you 2.4x boost even in weather as cold as -20 degree Celsius.

In many parts of Canada, -20C is a mild day in January.

Effective functioning down to -30 would satisfy the southern third of BC, southern Ontario, and the Atlantic provinces. We're close to that point now and we're starting to see adoption in those warmer climates.

Once heat pumps function down to -45C they'll be suitable in 99% of Canada and they'll see wide-spread adoption.

They don't need to be super efficient at the lower end of their operating temperature, but they need to work. Since most of the operating time is at warmer temperatures, inefficiencies at the lowest temperatures don't matter so much.

You could get 100 MHz IntelDX4 486 chips, released in 1994.

ARM didn't release ARMv8-A until 2011, 8 years after the first AMD64 CPU was released in 2003, and 10 years after Itanium in 2001.

I'd say ARM were the last to catch up.

Gasoline is significantly more expensive than 50c/kwh.

Maybe in countries where gasoline is very expensive. 50c/kWh electricity is very expensive.

Gasoline has about 8.9 kWh/l. At $0.50/kWh, gasoline is worth about $4.45/liter in a theoretical 100% efficiency ICE.

A modern, efficient ICE (e.g. Skyactiv) gets about 40% thermal conversion, bringing the equivalent value of the electricity down to $1.78/liter ($6.74/US gal) in terms of gasoline.

An average efficiency ICE gets 25%, making the equivalent value $1.11/liter ($4.20/US gal).

Gasoline is cheaper than 50c/kWh electricity for a lot of vehicles.

Indoors, no sun, sitting? 65 will feel very chilly.

65F is the perfect indoor temperature for me. Comfortable shorts and t-shirt temperature without sweating. Not chilly at all.

I couldn't read what you wrote. Is it encrypted?

I use triple ROT-13 as it's more secure than a single round.

What is the challenge with automated sorting of black plastics?

Now do the same battery calculation taking into account winter heating and summer air conditioning. The 8.5 mpg figure is with air conditioning. They get 14.7 mpg without.

Stop and go situations are definitely where electric vehicles win the most, but they are still more expensive than ICE and lack some capabilities. This will give USPS a good opportunity to test electric vehicles everywhere they operate and to determine any shortcomings before committing wholesale on the next iteration. It would be terrible if they replaced all their vehicles only to find out they can't do the job 4 months out of the year in North Dakota or something like that.

Puerto Rico is US territory. If you're an American living there, you're not an expat.

With a four digit uid, you should know it's tradition to not read the article ;-)

Linux already dominates the world. Very little doesn't run it at this point. It's so dominant that MS had to start including it in their OS as they were losing developer market share from lacking it. About the only place it hasn't taken over (yet) are desktops and laptops.

You omitted the US government from that list.

They'll definitely go after boats once the satellite backhaul is up and running: the fleet of ocean-going freighters is much bigger than passenger-carrying aircraft. And those freighters have crew on board that would love to make video calls with their families and watch Netflix.For ship owners/lessors, the expense of Starlink is minimal for the quality-of-life improvement for their crews. That's not to mention cruise ships that would probably use multiple terminals, or those cruising in small craft who currently use Iridium when outside of cell range.

The satellites are already passing overhead, so the only real challenge will be integrating some kind of pendulum to keep the antenna reasonably aligned in heavy seas (beam forming can only do so much).
