Maybe. I don’t like Elon or Trump, but I wouldn’t begrudge anyone for entering a raffle for some of Elon’s money.
Is there any downside to signing up for the sweepstakes besides having to sign a pledge?
Team member: “Maybe it’s bone spurs.”
Boner: “It’s never bone spurs.”
Harris and the Democrats want to keep exterminating Palestinians at the risk of losing the election and all the subsequent consequences like court appointments. It’s demented.
Why can’t it stay liquid?
Well, the water is necessary for for life support and needs to be sourced somehow anyway. It kind of sets a minimum crew and passenger capacity if you want to make the most use of your shielding water.
Water doesn’t have to be a liquid, but don’t actual spacecraft typically contain liquids during wall of those cases? What do you mean?
I don’t think it works that way. The water slows down the neutrons so that when and if they get to you they don’t have enough energy to hurt you. The radiation doesn’t contaminate the water any more than a microwave oven does.
Since the astronauts need water to survive, why not line the spaceship with reservoirs of it to provide the shielding? Or does water not block space radiation well enough?
Uh huh, and how do those numbers compare to the number of eligible voters who simply didn’t vote at all? Maybe the Clinton campaign should have just done better campaigning in those states, or offered a better platform.
This article is so badly written it’s almost unintelligible.
Trying again doesn’t necessarily mean trying again right away.
They could have tried again with another booster and landing pad.
If the developers could fix search, it would go a long way in improving Mastodon.
I was hoping for a new season of Rick and Morty.
Never post your resume or sign up for LinkedIn in the course of a job search? Never use a dating site? Never buy a domain? Never pay property taxes? Never go to court? I see your point, but never revealing your info online isn’t realistic or even a choice for most people.
Okay, but this application only requires 1.9MWh on board. That would be about 57kg of hydrogen. The required capacity would actually be less since the hydrogen refuel time should be significantly less than recharging a battery. Anyway, I just doubt very much that 11,900kg storage vessels and fuel cell would be required. There’s simply less dead weight in a hydrogen vehicle as well as better performance and less externalities associated with battery production and disposal/recycling.
As for the efficiency of hydrogen production and delivery, it shouldn’t matter. We need to produce it anyway for emissions free steel and fertilizer production. The real problem is that we don’t have enough emissions free energy production, which isn’t one that battery vehicles or storage facilities solve. The current paradigm is one of deficit in order to create a market and I think battery storage unfortunately facilitates that. Instead, we need to build out capacity so that there’s almost always a surplus of electricity with the extra getting diverted to hydrogen production. It should be rare that the process is reversed to turn hydrogen back into electricity for the grid. That hydrogen is currently too expensive is the result of bad policy, which BEVs just reinforce.
I meant apart from the hydrogen fuel costs. It’s not obvious to me why the labor and maintenance costs of hydrogen powered mining vehicles wouldn’t be greater than that of the battery powered versions and the attendant charging/battery swapping equipment.
Oh, gross. I don’t support any of the amendments.
