NDB Battery outperforms Tesla’s 4680 Battery System ☢ Radioactive Diamond Battery runs 28,000 Years
It’s powered by nuclear waste, but still safe for humans.
In less than two years, you might be able to buy a smartwatch—powered with a radioactive diamond battery—that will outlive you and your progeny for generations.
The potentially game-changing battery comes from the San Francisco–based startup Nano Diamond Battery (NDB), which lauds its namesake “high-power diamond-based alpha, beta, and neutron voltaic battery” for its ability to give devices “life-long and green energy.” Imagine: Just one battery could power your insulin pump or pacemaker for your entire life (with loads of time to spare). Or it could provide the juice for a space rover, collecting Mars regolith samples for decades without any human assistance.
Those are ambitious goals. So, could NDB’s bold claims actually become reality?
First, let’s dissect the specs. To build its Nano Diamond Battery, NDB uses layers of impossibly tiny, paneled nano diamonds (for context, one nanometer is one billionth of a meter). Diamonds have exceptional heat conductance, which makes them ideal for electronic devices. In fact, they are the best-known natural conductor of heat, according to a publication by the University of Houston’s College of Engineering—and are three to four times more effective than copper or silver.
