- melling 4y ago“Between 1991 and 2018, the average price of the batteries that power mobile phones, fuel electric cars, and underpin green energy storage fell more than thirtyfold” THIRTY FOLD ISNT EXPONENTIAL. Please reevaluate the plan. It likely contains a lot of optimism and a few required miracles
- evilsetg 4y ago> THIRTY FOLD ISNT EXPONENTIAL. A * exp(b * t) = A / 30 => b = - log( 30 ) / t As far as I can see a thirty fold decrease does fit into any exponential curve if you have the right rate constants or times, so I don't really get what you mean with that.
