Well, again, batteries have issues vs. combustion engines. They don't deliver high torque as well, they don't function as well at temperature extremes, they require downtime for recharging, they're less impact-survivable, they have a lower energy/mass ratio, and they wear out faster than a combustion engine.

Even with electricity at 1/10th today's prices and gas at twice today's prices, I think most people will still prefer to at least have a combustion engine available in the car.

That means there will be a large market for liquid fuel. One advantage of Polywell is it could be used to produce cheap liquid fuel via gasification or similar tech, as Bussard proposed.

However, I suspect that plentiful, cheap electricity provided by BFRs will spur investment in battery growth like we've never seen before.

As with fusion, there's still a question of fundamental limits, and no one really knows for sure what they are. Some problems with batteries may simply be unsolvable; there may not be a chemical combination that can deliver a real competitor to the combustion engine.

I dunno, TallDave. Let's get together in a decade and see who guessed this one correctly.

Hehe. I'll bet it's still 90% liquid fuel.

Sorry, in what context? Unemployment?

U1: Percentage of labor force unemployed 15 weeks or longer.
U2: Percentage of labor force who lost jobs or completed temporary work.
U3: Official unemployment rate per ILO definition.
U4: U3 + "discouraged workers", or those who have stopped looking for work because current economic conditions makes them believe that no work is available for them.
U5: U4 + other "marginally attached workers", or those who "would like" and are able to work, but have not looked for work recently.
U6: U5 + Part time workers who want to work full time, but can not due to economic reasons.
