Good link!
I think you are being optimistic on the twenty years, but one really big breakthrough in energy storage could do it.
The Tech being developed by the two largest industries on the planet (auto industry & mobile device) will directly spill over to this application.
Think of how battery size vs energy density has improved over the past 20yrs. I fully expect battery capacity to replace faster processor speed as the driving force in these industries.
