Yes, but then you have to be able to have sufficient storage of H2. I'm not sure if that's there yet. It's a highly flammable, very light gas that needs to be stored in obscene quantities over a period of months.

Maybe I'm too late, but there's one other applications that might one day reach the average consumer and that's quantum encryption. So the basic idea is that if you send out signals that have specific spin states, so it could be either up or down, then nobody could intercept that signal without you knowing it. Because if they intercept that signal they will mess with it causing some of these spin states to flip.

Now you could argue that they could piece together the original information, but with real signals that is extremely unlikely. You have to consider that most real data is extremely large, literally millions or billions of individual bits. Plus they already have an encryption, because the information will probably be in a format that is readable to a certain programm. You can think about it like this: if you opened an image in an editor you could still read the information in the image, but it will look like gibberish. If you know change random values here, it's impossible to decode this information again. Plus you will also get random information, because the would be hacker will have messed with your signal too.

But, yeah if this will ever hit average consumers, who knows.

Yeah, I meant the headline.

This makes it sound like wind energy is somehow competing with solar energy, which is complete bullshit. They complement each other. Wind energy is stronger in the winter and solar during the rest of the year. That's how you can even make a fossil fuel free world possible.
