  Bunny is now back in the Disunited States for a few weeks.  Monster sized cars and trucks.  Single sized snacks large enough to feed four.  Horrid TV.  No way to go shopping or do anything outside of the house without a car.  The weird and complicated medical system. Bunny has been away too long and could not live here.  Now, too strange and uncomfortable.  Well, that is just Bunny.   Has a long span of time away from something made it too difficult to go back?

Techspot reports : Coin-sized nuclear 3V battery with 50-year lifespan enters mass production A Chinese battery manufacturer has developed a breakthrough, sparking a worldwide race for compact nuclear energy. The innovation is a small coin-sized battery powered by a radioactive nickel isotope that decays into stable copper. While the initial cell is relatively weak, it can easily be layered to provide more power for up to 50 years. Energy storage technology has reached a transformative milestone as the BV100, a miniature atomic energy battery, enters mass production. Popular Mechanic notes that the coin-sized cell from Beijing Betavolt New Energy Technology can provide juice lasting up to 50 years without charging or maintenance. The BV100 harnesses energy from the radioactive decay of its nickel-63 core. The two-micron thick core, sandwiched between two 10-micron thick diamond semiconductors, efficiently converts the isotope's decay into electricity. Its modular structure allows ...
