@gcvsa@mstdn.plusThe thing you need to understand about #electriccars is that the Earth does not possess the resources it would take to replace the current number of internal combustion engine #vehicles with #EVs of equivalent capabilities. We don't have the capacity to manufacture the required #infrastructure or the #batteries. The sooner people realize this, the sooner we can get to work on #rebuilding #society without the idea that everyone should or can have a #car.
Obviously, to some extent, EVs are better than ICEVs, but in this case, "slightly better" has taken the place of real solutions.
I am in favor of low-power, low-speed, short-range #NEVs (neighborhood electric vehicles), #motorcycles, #ebikes and #emobility devices.
I am not in favor of #EVs meant as a 1-for-1 replacement for #ICEVs, with 500+ Km ranges and 100+ Km/h speeds.
It is the speed, range, and cargo capacity of motor vehicles which is the real problem, not their fuel.
#PrussianBlue pigment (ferric ferrocyanide) might be a key component in solving this problem. Although Na-ion #batteries made with Prussian Blue cathodes have less energy density than Li-ion batteries, they have exponentially greater #recharge cycle durability, thousands of recharge cycles without degradation, compared with a hundreds for the best Li-ion batteries, cost far less to produce (one-quarter to one-third the cost of Li-ion), are generally safer, and don't rely on rare minerals.
Prussian Blue/Na-ion batteries are also capable of operating as grid-scale storage to smooth out power delivery of discontinuous generation sources, like wind and solar, and help meet peak demand loads.
