Of all the things that'll destroy the environment, straws are not one of them.
And unless you figure out a way to prevent the sun from going red giant, this planet isn't going to last forever. But even before then, we'll probably see a comet impact or large-scale volcanism that'll screw things up pretty nicely by themselves.
Given that almost all GA accidents are caused by the pilot and the remainder are due to single engine failure, it's pretty easy to mitigate those risks. For a commercial flight, you can afford to have 2 well-trained pilots and 2 engines on every plane.
"EV's with subsidies" is not a good thing for the environment. If EV's were more efficient overall than the cars already in use, they wouldn't need subsidies to appeal more to consumer opinion.
I agree with most of your post, but if the subsidies were there to make up for the lack of a tax on the externalities of using gasoline, then it would make sense. Could it be done better as a tax? Yes. But it's not that big of a difference.
Amongst commonly used Li-ion battery chemistries, lithium cobalt oxide has the highest energy density. Cobalt is the next-door neighbor to iron in the periodic table. In the future, we may see lithium sulfur batteries, which are better. But it's still nowhere near hydrocarbons, which consists of some of the lightest elements: O, C and H.
One kg of jet fuel contains 42.8 MJ of energy. To match that, you would need 23 kg of LiS. If a jet normally carries 5 tons of fuel, now it needs to carry 115 tons of batteries. And since a jet can't simply take off with so much extra weight, it must either replace what it was carrying - passengers and luggage - with batteries, or fly a route that's only 3% as long.
Actually nuclear energy is pretty easy to extract, so easy that it tends to happen all at once with a big boom. The nuclear reactor is mainly there to slow it down enough to be useful.
I don't see how a comparison of families vs. general population excludes genetic changes. You don't have the same genes as your parents. You have a mix of their genes + some random mutations. Most of those mutations are going to be non-expressive, but some will be negative, and a very small amount will be positive. Since there are genes affecting your intelligence, then just based on genetic drift, you will not be as intelligent as your parents.
Not to mention there is a whole field called epigenetics, which studies gene expression. Even with the same genetic code, you can have very different results based on environmental factors.
In the short term. At some point, the absolute temperature is going to cause problems. Even now, humans are on the verge of not being able to live near the equator. They're forced indoors or underground during the hottest parts of the day. If the temperature went up by another 10 degrees Celsius, it will not be survivable.
Plenty of value in... doing exactly what other people are already doing? I mean, I don't see how he's improved anything. Maybe there is value in creating more competition, but any other company could've done the same.
Whether you make money on it or not makes no difference to me, but I find it somewhat amusing that you have the same tone as those people who bought bitcoin at $10,000 and saw the price reach $19,000. They were right... for about 3 months.
I saw a documentary about continuous boring years before Elon "invented" it. They used pre-fabricated concrete panels that gets attached to the walls as soon as the bore head goes past it. Another documentary I saw had them spraying fast-curing concrete instead.
As for using materials from what was dug up, that really depends on what you're digging through. If it's mud slurry, you're going to have a big problem trying to turn it into concrete.
Sorry, Google is not in San Jose, it's in a neighboring city called Mountain View, which is doing just fine. Whether San Jose is struggling has nothing to do with them.
Seems like this would have the unintended side effect of creating competition for those component suppliers. I'm sure all of the Chinese electronics manufacturers are now scrambling to figure out what parts they're importing from the US and whether they can find an alternate supplier.
Note that the "haircut" is no different from an instant 47.5% inflation, except it's not as effective against people stashing money under their mattresses.
Recycling doesn't have to be profitable. It just need to cost less than the alternative. As landfills fill up, it will become a scarce resource, and access to it will become costly enough to justify recycling instead.
It's actually not, at least according to most mathematicians. Infinity minus 1 is still infinity. You could, however, use a googolplex or Graham's number of years, which are most definitely longer than the heat death of the universe.
On the other hand, the current definition of author's life + X years actually does not fit the definition of a "limited time", since there's no telling how long someone can live. We might figure out the key to eternal life, or failing that, keeping people in stasis indefinitely.
I'm not particularly bullish on Tesla, but even I don't think you can call it until it actually goes belly up. Even at current loss rates and assuming they can't get more investments, Tesla still has a couple of quarters to turn the ship around. Anyone longing Telsa is taking a big risk, but they stand to gain a lot too.
At the very least, they're smarter than the people who put in preorders, those are just futures contracts with no delivery date.
Elon has a lot of great ideas and makes a lot of promises. But until an electric truck is sold by the thousands to shipping companies, there's no point bringing it up. Where's the $35,000 electric car that he promised back in 2016? Oh, right, it's actually $50,000.
The railroads should design very low floor flat bed cars. Containers should have a small batter and wheels to "self" drive and get off the road tractor trailer frames and get on to railroad cars and vice versa. The battery should have some small range, like 1 mile at 10 mph.
I don't see how this would be faster than using cranes. Or cheaper for that matter.
Even in smaller towns like Modesto, CA you can get around without a car.
You certainly can. I mean, if you have 2 feet you can travel the entire continental US. Whether you want to depends on how much your time is worth. A 7 minute drive from the Modesto Airport to downtown is a 36 minute journey by public transport.
Being much further from the coast than other states, Nebraska benefits more from other states' roads than others from its roads. If Iowa didn't build connections from Illinois to Nebraska, then it would be much more expensive to ship goods to Nebraska.
So it really should be Nebraska paying Iowa and Illinois for access to shipping routes in the great lakes, rather than Iowa and Illinois paying Nebraska to access Wyoming.
That said, there are other reasons to support Nebraska financially.

So... how exactly is your electric plane going to propel itself without air?

The Rate of global warming is the biggest issue.

They're forced indoors or underground during the hottest parts of the day. If the temperature went up by another 10 degrees Celsius, it will not be survivable.
You can do even better by actively going out and killing them.
Or run an abortion clinic. Then you're killing the problem at its roots.

Meanwhile, pirate sites receive a surge of users.
Engines designed for leaded gasoline can run on unleaded, provided the octane rating is high enough.
Besides, the gas station isn't going to check what kind of engine you have before selling you gas.

Wouldn't be a bad idea. It might be cheaper to move the telescope elsewhere. Or even write some software to deal with the interference.
envisaged... expected to be... can be designed...

Canada is 1/10th the population of the US. On a per-capita basis, they're twice as bad.
