@CelloMomOnCars @falcennial @pixelpusher220 Shure, the overhead of a #FuelCell will not.make.it.practical in a #Smartphone for the foreseeable future, and #SodiumWetcells are slowly entrenching #LiFePO4 cells territory.

I do however expect that for #EnvoirmentalProtection alone, we'll see #Lithium cells being slowly phased out in a few decades like #NiCd, #mercury and #lead before them.

• The only reason #LeadAcid wetcells are still used as #CarBattery is because they are disgustingly cheap and can provide high amperages for starter motors. Their weight inefficiency is not of big concern in cars.

Likewise I'm confident we see first #LiFePO4 then #SodiumWetcells then #FuelCells take over.

• On the flipside, I hope we'll see more #BatterySwap systems that'll use standardized #LiFePO4 cells (maybe not a giant stack of 21700's on cars, but on #eBikes and maybe 14500's #MobileDevices) which could solve the #charging speed problem.

In fact I'm confident #MethanolFuelcell will be used as drop-in replacement for (diesel-)electric buses simply because of scalability and fire safety alone.

• OFC the superior solution for regular bus lines are trolley buses, but being able to refuel on long-distance trips will certainly help conversion with long-haul bus services and #trucking beyond the "last-mile stop & go" delivery where drivers have their 8hr shifts and trucks can "slow-charge" at the depot at night.

In fact, #DeutschePost literally bought up an #electric #MiniTrick #startup just to get the "#CityScooter" #BEV|s made for them, and for couriers that only do stop & go these work fine.

The replies to the (above linked) video saying "Why battery swapping failed" point out many of the reasons given in the video are either out of date or that there are alternative solutions today making the idea practical.

I encourage everyone to read the comments after watching the video. #EV #BatterySwap kiosks #GreenTech #GND
