Does this mean the ill-informed decision makers are finally realising that the "phase out" targets of ICE's, gas boilers etc are totally unrealistic and unobtainable?
Eco rethink.

Toyota have announced a new type of battery that would give an EV a range of 650 miles with a re-charge time of 20 minutes. If true that would be a clincher if:
1. It doesn't cost a fortune.
2. It doesn't require an 80Kw charge point.
3. It doesn't suffer from thermal runaway on your driveway (or in a packed carpark).
I'm sure you've know the maths Bob. With the average size of an EV battery around 40Kwh with some much larger, to fully charge that in 20mins will need a 120Kw charger. OK, that's from flat which ideally will never happen but it'll still need a charger much larger than currently available for domestic use. With a 100Kwh battery, that's a 300Kw charger. Battery tech may improve power density but you can't get out more than you put in.
We keep hearing, and most will know, that Hydrogen tech is the only long term answer but very little about any planning or investment to implement it.

The only long term answer is to drive less.
That's crazy talk
