Georgetown University researchers have discovered a new class of strong magnets that do not rely on rare-earth or precious metals—a breakthrough that could significantly advance clean energy technologies and consumer electronics such as motors, robotics, MRI machines, data storage and smart phones.

    I appreciate where you’re coming from—batteries require dangerous materials and chemicals and also have health and environmental impacts.

    With that said, you are not describing batteries—battery means “energy storage” in this context. What would you suggest for that? Air pressure? Water + gravity?

    What about for local or portable storage?

      Agreed. I mean electrical batteries suck.

      Unfortunately cars can’t run on batteries that don’t suck. Which is why we need transportation that’s grid tied.

        Yeah, I mean generally, fuck cars. It sounds like you’re basically saying “more public transit” which I support.
