@CppGuy One word: #Tetraetyllead

IMHO it'll be inevitable that #Methanol #FuelCell-based #EV|s will be the future simply because:
1.#Lithium is scarce & expensive
2.#refueling will always be faster than #charging
3.#EnergyDensity of Methanol exceeds that of any #battery
4.#FussilFuel #Corporations can simply switchover pumps and flex their #EconomyOfScale and existing #Logistics to flood the market with cheap Methanol even if it has to be made 100% sustainable and without any fossil resources.
5.#EnergyStorage is another problem and #FuelCells can replace both #EmergencyPower systems running if #Diesel as well as the average #gasoline #generator.

Not to mention there needs to be #SystemChangeNotClimateChange and that necessitates way better #PublicTransport, regardless if #Trains, #Trams, #Trolleybuses or #FuelcellBuses (in that order)...

  • Otherwise shit won't change.

OFC what any #BEVs won't fix is the fact that most particle emissions are #tire #brake #dust...

  • And those are inherebtly unavoidable.unless we want to sacrifice #RoadSafety!

@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.

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.
