Can someone explain this a bit better? I'm not exactly getting what these are. So they are nanogenerators, which coulkd be used as a component of all electricity-generating technologies? The article specifically talks about them converting kinetic energy into electrical, but i'm confused by the solar cell comparison. Wouldn't these be implemented into new solar panels to increase their efficiency? It seems like these still need a "fuel", like all energy-generation methods?
It's an apples-to-oranges comparison. The idea here is replacing solar usage with kinetic energy in certain applications so fewer devices need an external power source and therefore wiring. It would also reduce grid use (by a minuscule amount), but I'm assuming the solar comparison is solely because both produce a DC current.
ahhh got it. Thank you!
