Nice to see a down-to-earth gradual approach instead of billion dollar projects for big business being hawked. Of course there are already thousands of amateurs doing gas to electric conversions. All of those could collect real world data using a cycle analyst (for power and regen etc) and gps. Then there could be real world tested recipes for the most common types of cars (from commuter cars to light delivery vans)
I particularly liked the statement that the strength comes from the combination of being able to do things with your brain and hands. Too many university people think brain is enough, and too many people outside univ don't think enough (flame suit on...) (Actually to be more precise one problem in universities is that people think too narrowly).
There was a lot of hawking for the supercapacitor power cache idea. However, it was disappointing not to see it proven by real world tests. Just how much more life does it give to modern battery chemistries?
There could also have been a better balance of technologies. Bicycle commuting was mentioned I think only for a few seconds, but ebikes hold even more promise to green the world than heavy cars. Lightweight cars, such as the Aptera are also on the horizon. On average a converted regular heavy car converted to EV might halve CO2 emmissions, (and move the source of pollution from city cores to power plants). A lightweight car (Aptera etc) can do the same driving at a quarter CO2 or better, while an ebike is 1/10 to 1/20th.
