It’s always the fuel of the future because it’s too expensive. Lithium sulfur batteries or something similar are coming soon with energy densities 4x li ion. That’s good enough for long haul trucking and short to medium range aviation. Hydrogen could be the fuel for container ships some day.

It’s not lazy it’s accurate when it comes to hydrogen. The only cheap source of hydrogen is methane right now. Once solar and wind power are built out to the point we have surplus electricity then you can start making hydrogen essentially for free via electrolysis. But until then petroleum companies are going to do what companies do: lie cheat and steal to stay in business.

It would depend on ocean current depth wind patterns etc but the oceans are massive, beyond our understanding. We can never make enough hydrogen to alter ocean chemistry assuming the byproducts are properly dispersed.

They were feared missing?

They’re a poor country. It’s amazing that they’ve accomplished what they have

The red bull guy wasn’t in orbit. He did the equivalent of climbing a tall ladder. Shedding orbital velocity is the problem.

If it’s any consolation, your grandchildren will only see a 12” sea level rise. It’s your great great grandchildren who are fucked. Ask yourself how important your relationship is with your great great grandparents is. That’s right, they’re strangers you don’t know or care about. And that’s why we’re in this mess.

Time to leave the afghans to their own misery imo. They want our money but not our values. If they want to live in the Stone Age , fine. Cut them off

It’s not “extremely toxic” unless you don’t have the biochemistry to deal with it.

This is good news. Put the oil back where it came from.

Cherenkov radiation is probably the best real life Hollywood-like radiation glow. I think a good way to think about this is to remember that for our eyes to see something “glowing” it has to be emitting by definition visible light. But why would radioactive material emit viable light or trigger the emission of visible light when again by definition it’s emitting “radiation” , meaning either neutrons, gamma rays, electrons, or other high energy particles? None of those radiated particles are visible. However , there is a phenomenon called “phosphene” where radiation triggers the perception of light, or where the radiation causes Cherenkov light to be released within the eye itself. Radium for example, while not making girls actually glow, does appear to glow faintly blue in the dark. This is from high energy electrons striking nitrogen in the air. Maybe you could use that .

Woohoo I’m saved !! Wait , does this not apply to dudes ?

What’s confusing is that the brain doesn’t need insulin to use sugar. And yet insulin is an important hormone in the brain

Impractical for small suburban lots/homes. Quite feasible for larger properties. Of course water would probably be used as it’s readily available. Or maybe dirt /sand?

Concrete gravity storage has been demonstrated to be scalable. You just use more blocks of the same size. Pumped hydro is severely limited to areas that can store water without causing ecological problems. Also concrete doesn’t evaporate.

you can't have a 5 second toaster because toast requires slower heating. too fast and you get cold bread with burnt outer layer.

I believe the national ignition facility may be interested in your above grant proposal.

Marketing triumphs over physics again!

Well think of it this way: unless our brains are recording the audio exactly the same way a computer does , there has to be a way to time-stamp the information. Otherwise it would be just a jumble of incoherent sounds. Take what I’m writing for example: you are reading from left to right. So all is good. Now imagine if every word I typed was written on a separate scrap of paper and put into a bag. You put your hand in the bag and pull out words randomly. Total nonsense. But if I put a number on each one you could reconstruct the meaning.

Yeah I must be missing something. Maybe what they’re saying is the audio is first encoded, then sent to the brain, then analyzed and decoded but because the way the brain “saves” the audio , it needs to keep track of which sound was first. On a CD the data is stored in space, in a line. In digital storage there is a file. In your brain I’m guessing it’s not so linear

It seems bad at first but gutting is often less work overall. I’d take it down to studs, probably only one day of work. Wear an N95!

I have lots of lights that are soaking wet for the month of December and they don’t ever trip my gfci. It’s weird honestly. In my experience gfci just go bad and it’s easier to replace them after some basic troubleshooting.

I hate mastic so much. It loves water ! Scrape it out and use concrete or bondo

What is this camouflage font??

In a separate human trials mentioned in the article the subjects had to spray something in their mouth daily for several months so I’d say possibly yes the pills might daily.
