- sam_goody 4y agoNo market lives up to their hype, but I have a feeling that the two worst offenders for consistently [10+ years] talking about world changing breakthroughs that underperform is battery tech and self healing dentistry. That doesn't mean there are no advances in batteries - Tesla in particular changed the way we look at large and fast charging deployable batteries [in multiple industries] - but where are the major breakthroughs that are announced untiringly? OT: There ought to be another award for most overblown hype (though less consistent). My contenders: Fusion, AI, Quantum computing and Web3
- peter_d_sherman 4y agoAny well-made capacitor, if kept within voltage tolerances, has in theory an unlimited lifespan of charge/discharge cycles... This is because where the charge is stored -- there are no chemical reactions, no charge chemical reaction and no discharge (reverse) chemical reaction... Batteries based on chemical reactions -- typically have a limited lifespan because the charge/discharge chemical reactions -- fail for various reasons after certain amounts of cycles, because the chemical reactions fail... So it makes sense -- to try to make batteries where chemical reactions are either not present (i.e., truly capacitative), or severely limited -- in an attempt to prevent the chemical breakdown which characterizes battery failure...
