I hope society ends up settling on some fluid based sustainable fuel in the end. Maybe it's fuel cells, flow batteries, or even a combustible. The advantages of weight and refueling speed are hard to beat.
- dontlaugh 3y agoTrains, trams, microcars & bikes replacing most road vehicles and biofuels for the remaining ones would be much better overall.
- osigurdson 3y agoTrains are fine but cannot replace cars.
- dontlaugh 3y agoNot completely, just the vast majority. Especially for freight.
- osigurdson 3y agoIt does seem far from where we are now. However, if someone wants to build trains (without me paying for it in taxes), I will happily buy a ticket if it is convenient and cost effective for me to use.
- bluGill 3y agoFor 30% of the population they could completely replace cars. For another 50% they could let you go from being a 2-3 car family to a 1 car family (more likely a truck - either to haul tools, or to tow the boat) Of course to replace cars much a comprehensive network that would be expensive to build in the short run. (in the long run cheaper than the road network which would need many less lanes)
- scythe 3y ago>biofuels Absolutely not. The land use impacts are enormous.
- lm28469 3y agoNothing will be "sustainable" with the predicted number of personal cars
- djaychela 3y agoNone of those work at the the moment though. And I'd suggest the advantage of not destroying the biosphere outweigh being able to refuel quickly.
- scythe 3y ago>flow batteries Not a type of fuel. The only advantage is that they're easy for hobbyists to build. Otherwise it's just a battery with more stuff that can break.
- goda90 3y agoThere are systems being developed where the discharged electrolyte is pumped out of a vehicle and replaced with charged electrolyte.
