I see two arguments here, both correct. Muddie wants to drive from Noosa to Sydney with minimal stopping time and it is true that there is no production electric car today that will do this.

Acorn argues that the average commute is under 40km per day thus electric cars are perfect - also correct. If your 40 km commute consumed say 9KWh of energy it would take less than 4 hours to top that up at home using a small charger plugged into a 1OA wall socket.

As an aside, if you accept that an electric car consumes 18KWh/100 km, then at 30 cents/KWH, it costs you $5.40 to travel that 100km

Meanwhile, a petrol car using 8L/100km costs around $11.20 to travel 100km. About double the electric. And with almost zero servicing costs.

Admittedly, cost and life of battery packs is a whole other story and you enter the Disallowed world of car salesmen when you try and quantify these.

ON a positive re battery development.

TeraWatt’s solid-state battery prototype achieves energy density of 1,122 Wh/L

Silicon Valley startup TeraWatt Technology has announced that its prototype 4.5 Ah solid-state battery design achieved a record-breaking energy density of 1,122 Wh/L (432 Wh/kg) in validation tests conducted by third parties, including the Japanese testing service TOYO System.

TeraWatt says this 4.5 Ah design, which is branded as TERA3.0, will be available for select early adopters in 2021 and for full release in 2022. The company continues to further iterate the TERA3.0, and is developing additional designs, including different cell formats, sizes and energy capacities.

(about 2 to 4 times that of lithium ion.).

If you can 1/2 the Battery weight & have double the power then a step in the right direction.
