Comment Re:This has happened before. Humanity excelled. (Score 1) 187

It probably gets downplayed today because it had been already exaggerated by people like you to inordinate levels of relevance. For example, just because it's somewhat comparable to early 20th century situation doesn't mean we haven't overshot it already and aren't well on our way to greatly overshooting it.

Comment Re:The actual real problem with Mars... (Score 2) 102

The Curiosity mission cost $2.5 billion and that was a one-way trip for a robot.

A significant part of that cost was because of the inability to deliver large payloads to Mars cost-efficiently. It seems that Red Dragon is poised to offer a standardized transportation system that could land something like twice the mass of the MSL rover for half the money, and that could not only save you transportation costs (which included not just spending $200M on a top Atlas V configuration launch but also having to develop a "one-off" custom lander), but it could also remove some of the design constraints so that an equivalent mobile robot could be built cheaper, even if it weighed a little bit more in the end because of less money spent on shedding weight.

Comment Re:Efficiency is useless. (Score 1) 127

Cost is not everything, that is pretty dumb economic thinking. Cost efficiency is everything, the return on capital investment.

With solar panels, it turns out that these two correlate quite nicely. With the exception of potential panel area limitation, cheaper panels are also more cost efficient. Although the US is also an outlier with fixed non-hardware costs (permits, labor etc.), so your experience may be somewhat different than in other parts of the world, where the cost efficiency of ordinary panels is much more obvious.
