The End Of Fossil Fuels.

RE: The End Of Fossil Fuels.
It looks like this genius hasn't figured out how to use the quote feature. HINT: Don't include your reply within the quote tags.

Anyway, my bet is zero-point energy.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

Wrong movie. Hermione is a character from the Harry Potter films. King Isildur is a character from Lord of the Rings.

What short memories we all have here.
Years ago we learned it was the Veegtron that would solve all the world's problems and answer all the questions.

RE: The End Of Fossil Fuels.
True story: I once calculated how much energy one could get out of dark matter particles if one could stop them flying through us and convert them to energy. It was 12 Watts per square meter, or about 1..5% of a solar panel.
It's surprising that it even comes out at such an everyday scale (could have been 5 orders of magnitude lower or higher if you'd asked me), but from such a cool concept I would have hoped that it could do more than power my toothbrush

More importantly Alex, and aside from a practicality perspective, what cost is involved in harnessing these particles.
eg: cheaper than a 1.2m x 1.2m solar panel (assuming 80% at best efficiency)?

That's difficult to say. We don't know the properties of dark matter particles, we only have model hypotheses. For the usual ones (e.g. weakly interacting massive particles (wimps) or Axions) there is currently no tech to harvest them (otherwise we'd have discovered them) but I can speculate. For wimps, one could imagine a stream of high energy particles which would force them to undergo weak interactions. All unimaginably expensive and inefficient. I would figure a 1x1 m prototype to involve a wakefield particle accelerator which costs millions and needs a few megawatts to operate 🤣
But who knows, maybe I am missing something ingenious

sorry, that was me asking stupid questions. Dark matter/energy are placeholder names for the as yet undiscovered. DOH!

Yes, all we know is how much of it there should be (to cause the observed excess gravitation) and roughly how fast it would be moving, although that's where you have to choose a hypothesis. The conservative estimate would be our speed of movement through the galaxy.
