I expect that once all the current and future Joules are distributed, we will begin to see the next generation of:
NanoJoule
MicroJoule, (for very small Studio Apartments and Tiny Houses)
MiliJoule
TeraJoule
ZeptoJoule
KiloJoule
MegaJoule, (for commercial and industrial kitchens with really big pots)
PetaJoule, (designed specifically for the Trump Tower operations)
ExaJoule
ZettaJoule
YottaJoule.
I donʻt even pretend to understand those last three.
