California’s Bullet-Train Boondoggle
A lawyer familiar with the case mocked this argument as amounting to, “Damn the legal niceties, this mean judge is getting in our way.” – See more at: http://calwatchdog.com/2014/04/22/gov-browns-legal-strategy-to-prop-up-bullet-train-faltering/#sthash.Na3IFURm.dpuf
This is a problem that won’t be solved until California gets an intelligent electorate.
Space Solar Power
whatever you think of its prospects, low-cost launch will certainly improve them.
[Afternoon update]
Space solar power, visualized.
The Pacific Salmon Are Back
…and of course, the environmentalists hate it:
The point deserves emphasis. The advent of higher carbon dioxide levels in the atmosphere has been a great boon for the terrestrial biosphere, accelerating the rate of growth of both wild and domestic plants and thereby expanding the food base supporting humans and land animals of every type. Ignoring this, the carbophobes point to the ocean instead, saying that increased levels of carbon dioxide not exploited by biology could lead to acidification. By making the currently barren oceans fertile, however, mariculture would transform this putative problem into an extraordinary opportunity.
Which is precisely why those demanding restraints on carbon emissions and restrictions on fisheries hate mariculture. They hate it for the same reason those demanding constraints in the name of allegedly limited energy resources hate nuclear power. They hate it because it solves a problem they need unsolved.
I hope this means a lot of cheap fresh wild salmon in the stores this summer.
News On The Asteroid Bombardment
The B612 Foundation is going to have a press conference at the Seattle Museum of Flight at 2:30 EDT. It will be live streamed.
Public School Is Child Abuse
Example #15437.
The cop should be charged with false arrest, and the school officials should be sued within an inch of their lives. This kind of idiocy will continue until it causes pain for the idiots.
Earth II?
My thoughts on the latest discovery from the Kepler data, over at PJMedia.
Earth-Like Planets
by a researcher who says that planets that can accommodate LAWKI aren’t as common as some are saying.Base Camps
Derek Webber writes that in order to advance into the solar system NASA needs to take some lessons from Everest climbers.
Not to mention be willing to lose folks occasionally.
[Update a few minutes later]
Jeff Foust notes that there seems to be an emerging consensus that Mars is the goal, though none on how to do it.
Meanwhile, John Strickland says we need an integrated approach, with robots and humans. to get to Mars. He seems to be focusing on Mars surface water, though. I think we need to trade that with manufacturing propellants at Phobos or Deimos.
My take, as always, is that destinations are less important than capabilities. Put an off-planet space-transportation infrastructure in place, and the entire solar system (including Europa and Enceladus) is opened up to us. But Congress would rather build big rockets.
Big Asteroids Hit Us
…a lot more often than we’ve previously believed. I’m not sure, but I think that one of the reasons Ed Lu wrote the foreword to my book is that he shares my concern that our risk aversion will prevent us from mitigating the real risks.
