Can you imagine if you were not allowed to enter city hall to renew a business license because you sued the city about a pot hole? Or if you sued Ford about a defective car, and could no longer get an oil change at the dealer? We’re not talking about a personal home here.

I think the question is once you polish it, how do you keep it from corroding? Aluminum is no big deal, but most kinds of steel will rust, unless you pay the premium for stainless steel, which is much more expensive than plating. But that means you have to make the entire piece from stainless, not just a coating. So…

Different process, and in that case the chemical was being released into groundwater. Chrome plating at least keeps the liquid contained, but has the problem with vapors.

Above a certain size, it makes almost no difference. When it’s moving 60km/s there not enough time for the atmosphere to spread the rubble out. The outer shell still gets ablated, and if it’s large enough, the interior feels nothing at all until it hits hard rock at the surface.

Especially as SpaceX already has a DRACO rocket engine. (And SuperDraco, as well.)

The other demo where they moved it around a “stomach” and trapped the object is the impressive part. But probably still could have been done with an endoscope.

The part where they manually remolded it into the Lego shape again was effectively stop motion.

I try to do some hard braking every once in a while to keep it smooth. The brake controller mixes the regen and the brake pads, and the first half of pedal travel usually doesn’t even touch the pads at all, unless the battery is too full or motors too warm to accept any more regen. There is still a physical action…

They still train their brightest students with new(er) tech, possibly smuggled in from elsewhere, even if they don’t have enough computers to go around for the rest of the population. A lucky few have access to unfiltered internet, though probably with somebody watching over their shoulder.

Then what would you have done differently, if you were a coworker of the deceased? Keep in mind that they COULD NOT shut down the engine, because of an inoperative APU. Until they hooked up ground power, they need electricity inside the plane.

But the RATE of wear is substantially reduced, even compared to a much smaller ICE car. Regenerative braking by itself does not use brake pads at all. EV cars still have brake pads, because sometimes you need stronger braking than regen by itself can perform. But those are exceptions, unless you drive with a lead foot…

The quoted sentence mentions both tires and brakes. He says he agreed about tire dust, but not brake dust.

Exactly. Some families will always want something bigger than a car, and if the middle category is eliminated, (see station wagons) they will go up, not down, to meet their needs. So make sure the costs scale with the harm.

Only one state has a significant portion coming from coal. In most other states, it’s a mix of gas, solar, wind, hydro, and even nuclear, and if they have coal at all, it’s a tiny fraction. And even when/if it does come from just natural gas/methane, that still produces less CO2 than the equivalent energy from gasoline…

The key would be “comparable aircraft” because I doubt they are doing this for 777 or A380 class planes anytime soon. So putting longer wings on the smaller planes, which are more numerous by far, shouldn’t need major upgrades at most commercial airfields.

It takes the CPSC out of the running as the department to implement it. Maybe the EPA could, but it seems like they have bigger targets right now.

This might be an acknowledgment that most people reading a document these days will be using a screen device, and not paper. TNR and other serif fonts are great on paper, but sans serif has a readability edge when viewed on screen.

The window on the right side is very red. I assume the windows on the left are pointed away from the blast. But in any case, glass fragments are another big threat, so stay away.

My gas dryer is vented to the outside, and I think most are. Maybe some people don’t bother to attach the vent hose properly, but who wants all that hot, humid air in their house?

I thought for tornadoes, small inner rooms such as bathrooms, closets, and hallways were suggested because they are away from windows and have better structural stability if the roof fails. Even if one wall of the hallway falls into the other, there often remains a survivable space in between.
