What's amazing is that almost none of the calculations Thuderf00t does in any of his videos involves anything more than first-year physics. Most of them could be back-of-the-chapter exercises.
Yet these simple calculations can be used to destroy many phony ideas going around about new and exciting technologies, including ones being funded by government research grants and underwritten by renowned universities.
In physics, there is no penalty for using simple calculations to make big statements. In fact, if you can pull that off, so much the better.
All of this is quite disturbing to me, however. It tells me that we are truly living in Age of Bullshit, when the most "exciting" ideas in popular discourse cannot stand up to simple physics. Instead we are living in an age when science and technology seems to be based on how it all makes you feel.
If an idea makes you feel good and cozy about the future (the environment, social justice, climate, renewable energy, etc), then who cares if it doesn't stand up to basic physics? There has to be a way to make it a happen.
But no, sorry, we aren't going to have solar powered roads. Yes, I know you saw it on Facebook and shared it and liked it. So cool, right?. It's a great feeling idea.
No, sorry, we aren't going to have plastic roads, either.
No, sorry, we aren't going to have Thorium-powered cars.
No, sorry, we aren't going to have simple devices to allow poor mothers and kids in the Third World get drinking water for free from the atmosphere.
And, no, sorry, we aren't going to have the freaking Hyperloop. Elon Musk may or may not be a conman. Hard to tell, but the fact that the so-called Edison of our Era has yet to produce a single darn thing worth while for the masses should tell you everything you need to know about our current era.
All of this is probably heart-breaking for a lot of people. But that's the wonderful thing about physics is that it breaks your heart like that, and in that realization is freedom.
