Only affordable with massive government support which will happen in some places and niche markets like taxis, buses. The real costs are hidden and paid for with high tax. Only very rich countries can afford to use H2 for everyone. But EVs are much cheaper even if they are pricey!

At first hydrogen seems like the perfect solution to our automotive fossil fuel problem. It’s a pura, elemental gas that is everywhere, it can be clean, it can use vehicles similar to what we have and know (i.e. ICE), and in theory, can be refuelled easily. Unfortunately, even after many decades of research by many governments and large companies (e.g. BMW), serious obstacles remain: Storing it, it’s not always clean or when it is its unaffordable. Storage is one. Compressing the gas to useful quantities for a vehicle uses considerable energy and time. Using metals to absorb and release it has limitations. Storing useful quantities of one of the most flammable gases in a vehicle adds risk similar to a low explosive. Weight or volume of the tank is greater. When burnt in an ICE engine, hydrogen’s violent combustion breaks the nitrogen bonds in air and produces copious amounts of nitrous oxides also known as smog. If using fuel cells then these are laughably expensive. Useful only with extreme budgets such as in aerospace or marketing, not affordable for the masses. Always (since the 1970s at least), the same excuse is used, that these problems will be overcome with technology and the cost will come down. But the fundamentals remain and there is no known reason (by anyone) that they will change, at least as of now. It’s a bitter pill to swallow I’m afraid. It would be nice if H2 was the perfect fuel. Electric batteries have steadily become cheaper so hopefully EVs will become affordable for the working class

So what about the structure ?...

superficial...nothing about the tomb!

These hunting moments are really impressive. Thank you!

Toyota has already developed it.

boeing...

Bram stoker was labelled anti semitic for writing dracula stranger than fiction

Just like his Hyperloop changes transport. Elon is a joke.

Even if perfected, the hydrogen engine will likely never make it to market. Others have tried similar projects only for it to be erased by the wind.

Below is as above once you've seen this then you will know what true powerlessness is

Bill is not an astro physicist. He's not even a rocket surgeon!

Platitude - a remark or statement, especially one with a moral content, that has been used too often to be interesting or thoughtful.

yawn

I see no science here. It would help if the author of the video mad it clear what is a computer simulation and what is an actual image from JWT. As far as I can tell it is all a simulation.

If you want to scare somebody, get somebody other than a TV scientist. A real scientist perhaps.

What is amazing is Bill Nye, the Science Guy, is now a world renown Astrophysicist. What a secular miracle! Yes, the JWST is amazing and its infrared images are exciting, but we must remember that these new galaxies may have died billions of years ago and all we are watching is the faint afterglow of their one time existence. It's not nice to say, but this is OLD NEWS, like digging up dinosaur bones, its relevance to our current existence is minimal.

You never explain what is so amazing. You just blab on and on with total valley girl nonsense. What they really find is there is no difference’s in the galaxies they think are billions of years old and the ones near us.

So haha h 2 comment

Disconnected images with text give this a layer of doubt for any serious researcher

Dear god.....hours of slobbering sycophantic waffle put me to sleep.........................

'Ends all the Debate in Physics?' The clip literally says it has physicists debating whether to modify Big Bang Theory or come up with something new.

Well, JWST discoveries do NOT end all debate in Physics.. Rather it starts a helluvalot of new debates!

Seems to me like the old problem of making large-scale observations and the theories that describe them fit the observations and theories that are suited to describe the processes on the size of quantum physics and even below that size. Like expanding space can be observed - are there space-time units expanding locally at the level of 10exp(-33) and they struggle to fit macroscopically? No questions are answered yet and rather new questions arise - not eliminating the value of the ones we already face.

"More mysterious than we ever imagined". We are pretty small...

So the James Webb proves current physics to be wrong!!!! And everyone else with a science degree to throw their degree in the garbage. Lololol

Expansion is based on the wrong assumption that lights wavelength is constant, that is wrong. Wavelengths vary with the influence of gravity. And we cannot measure the effects of vast distances. The effect radiates about evenly from earth once again we are in the center of the universe and the earth is flat.

WEBB has a long way to look to find the first ever star

There are galaxies that are older thanthe big bang,maybe the big bang before the last big bang, [like a roman candle,]....

Your testimony that the "Gate Has Just Opened" is as quite blatantly flawed as all the other bulls..t that is espoused by anything other than the truth of sincere Christians.

worldsmasterofspiritsknightsofchrist,tm* remove thy dead ,remove thee bone boxes, take thee stones out and i shall go, I am your worlds master of spirits thy highpriest of thee knights templars remove thee gate and i shall go call my LORD -if I were Israel i would follow my orders asap for my time is short children . Maybe it is time too show thy world thy true LORD of well everything BUT be advised he shall judge everyone and every kingdom every city and every land .IAM taking a huge huge risk bye telling you that iam here ,Iam thy most holy highpriest of thee knightstemplars i know what too do children .I need not too kill any-cows for truly he paid thee bill already i do not need to tear down any moss for thy LORD has many sheep,i do not need Too build a temple for he shal be bringing his OWN Iam you true worlds master of spirits WE have been around for a couple of thousand years now When we went into Israel we got what we needed in order to for-fill this last task but truly make way for thy LORD I KIDD THEE NOT ! clear a path and make it stright ,woops sorry my spellcheck is off remove thy dead let us clean everything and make it knew ,folks Iam on a time line i shall do my part i promise then you might see two men who come to preach thy word do not try to stop them stay out of there way please Iam your keymaster kidds highpriestknightstemplars,tm*

It's not open and us totally misleading

great, il sleep so much better tonight now i know this, kind of makes you wonder if these really clever educated people just make stuff up if they dont understand whats actually going on..knowing that nobody can prove otherwise....

😢😢😢 Presumption is the acceptance of something as true although it is not known for certain. Assumption is a thing that is accepted as true or as certain to happen, without proof.

Lots of words, little if any new content. Could of done the video in 3 minutes or not at all.

Everything we learn about astronomy reminds us that we don't have a clue about the universe

That's funny 😂

I'm pretty sure that thing is a model A Ford launched into space in the '70s.

First comment 🤣🥳🤯

ummmm did you mean 'finally HAPPENED' ??

Only if God allows it

LMAOOOOO

😂😂😂 Its all BS. Earth is flat. How do I know. I'm a pilot. Get a telescope or Nikon P1000 and find out for yourself all these 'space' agencies are lying.

but it will Never Happen in my life time, or even in the life time of Man..

If something does not line up with the rules, They just change the rules. This is all based on biased speculation and guessing. My guess is just as valid even more so. But I KNOW that God created the universe. It is so obvious that God created the universe.

you would be saying we don't know anything we are just guess Even after all this time Einstein was wrong. Science is about making a guess and trying to prove it. we can not prove anything about space we know nothing.

You lost me at “billions” of years and a “big bang” if you say this then what is your proof for that?

wanna buy a bridge?

Me when I lie on the internet

anything bigger than the solar system is a black Hole, alas a whole galaxy, "60 times the graphics" rsrsrs
