Sure, if you only count the very light nano wire toward your energy density and not the giant mechanism to make it useful.
For now, assuming it pans out.
Remember that ~60 years ago, computers less powerful than the microcontrollers in your “dumb” appliances filled entire rooms.
Giant springs? I’m in. I want an EV but even more than that, I want a clockwork V.
In this case, it’ll end up looking more like a block of billions of microscopic springs. Still in the phase of interesting-lab-demo rather than something that’s production-ready.
Ok, and in macromechanical?
They claim it does a lot better than existing steel springs — scaling up to meaningful amounts of energy is a research topic.
Huh. So let’s see then. Thanks!
I expect that if this result is reproduced, we’ll see a bunch of people try.
