Elon Musk, CEO of Tesla Motors and SpaceX, doesn’t seem particularly impressed with Stanford University’s new hyped-up battery.
Researchers at the university claim the technology can fully charge a smartphone in a single minute. But Musk took to Twitter to urge caution over the development.
The billionaire inventor is warning people to stop getting over-excited about unproven products. Although Stanford’s battery hasn’t been disproved, it’s not yet seen results outside lab testing environments, BGR reports.
This week Musk, who knows a thing or two about technology and business, tweeted:
Battery “breakthroughs” need to state power *and* energy density (not the same thing), plus how long they last. They usually fail on energy.
