I was sort of getting that vibe from the article as well. Maybe the doctor in question had legitimate reasons for "why the group couldnâ(TM)t do some things and shouldnâ(TM)t do others". But the non-doctors, like the author for example, do not understand the reasons and as a result see this as being a jerk.

Arbitrarily high accelerations are not needed. What is needed is sustained low acceleration. Sustained acceleration at about 1 G, accelerating toward the target for half of the trip, and away (braking) for the other half, will make a 22 LY trip take about 23 years (as seen from the departure/arrival points).

Only if we allow it to. Right now it can not, because the prices are being manipulated by government subsidy. Not just the solar energy prices, but those of coal, nuclear, and wind as well.

It is a lesson we continually fail to learn: Industries built on government subsidy suffer when those subsidies begin to go away, even if the product itself is sound.
