The canisters aren’t what exploded. There was a leak that allowed the propane gas to first pool in the low areas and then build a deeper layer; if it was all propane he would have suffocated, so there must have been some mixing to make the mixture explosive.

Congrats? Car is destroyed. They would have her ID from the dealer for the test drive. Damaging the vehicles of otherwise uninvolved people? 

It doesn’t appear they are bricking it. They just no longer host the service this thing needs in order to operate. More like 3G phones didn’t get bricked in the US - there just aren’t any cell towers that will communicate with it anymore. I’m sure the main cost was having people to keep that service running and…

The explosion pressure can be as low as 10 - 20 psi. 15 psi over-pressure is the equivalent of a dive 33 feet deep in water.

Most clothing is made from dead plant material, hair shaved from animals, or converted petrochemicals. It’s been a while since metal has made up a notable amount of the outfit; the long bow and gun powder ended that long-time fashion trend.

Those states won’t have this law.

We have driver ed. There is not much to tell people that the number on the sign is the limit. What the US does not have is firm enforcement, which allows 99% of drivers to ignore all the limits, many of the road markings, many traffic signals, most turn signals, and so on. The drivers know they are there, they have no…

If the GPS receiver fails to function the car fails the next inspection.

Gallons per x miles more easily converts to dollars (currency) per x miles (distance.) So a car that uses 5 gallons per 100 miles at $4 per gallon, is easily multiplied to get $20 per 100 miles, which is the direct economic value people pay attention to.

The tracking data is continuously provided live and anyone can operate a receiver to gather it from aircraft in range; there’s not a way to delay it. What can be done is to allow the plane to transmit something other than the registered identification so it cannot be linked to the publicly available registration…

Who knows why this type of flight, but I think it is safe to say that there is a good chance any globe-trotting by Musk can be handled by Zoom, while a live concert with Swift won’t work quite as well. 

If you are cool the bees will be cool. I expect most of the stings were from bees landing on people and then people swatting or confusing them with a perspiration drip them rather than some crazed attack.

I think the problem is that the demand for pollination exceeds the food supply available for the rest of the year. There’s a massive need for a short period of time for pollination to take place, but there isn’t a massive amount of native plants to support the required population for the remainder of the season.

Male Cicada killers don’t have a stinger, but they bluff. The females drill holes in the ground and, being solitary insects, won’t fight because fighting means no more baby Cicada killers.

The best way to tell is this. Are there 100 of them repeatedly stinging you and more are on the way? Those a wasps. 

How is she supposed to save only herself? That emergency door doesn’t lock from the outside. Open it and go through to save yourself and that remains an open exit for everyone.

Do you know when it is time to replace the fuel pump on a 1962 Ford Falcon? When the windshield wipers stop moving under pedal-to-the-floor acceleration.

Put the car in neutral. That will allow the engine to produce some vacuum to assist the brakes and avoids locking up the steering. 

So, an early warning system that you cannot ignore to replace the water pump? Someone was too clever.
