I thought until recently that it was established that big birds flew in V formation to save energy. It is true. But it wasn't until last year that they had instrumented birds to prove it. In fact, the birds even... Continue reading

With the latest cold, the noise from the science deniers has become overwhelming. They don't accept the difference between weather and climate. Climate is about long term statistical statements. Weather is immediate events. They are not the same. The polar... Continue reading

Commercial launch of communications and other non-government satellites is already routine. Orbital has various non-government launches and clients already. Orbital also make satellites. SpaceX also has many non-US government launch clients announced, and three recent successful launches with non-NASA customers. The better question is when will there be enough customers to make all the launchers, facilities, etc. viable businesses in the absence of government clients and subsidies.

1) The climate scientists made the mistake of aligning themselves totally with on narrow political wing. Instead of arguing "here is the science, there are a wide variety of possible solutions to the problem" they present "here is the science and there is only this possible solution." That makes the science both a target, and an enemy to every alternative solution. 2) The discussion here illustrates one of the big problems with that narrow political wing. Nobody is including cost/kg of CO2 reduction in their discussions. It's absurd, but the current politics refuses to include this in any policy discussions. Given all the other social needs like education, healthcare, or personal living standards it's strange that cost optimization is not part of the discussion. In the real world, away from these political storms, the major companies have done that. One thing that leaps out is that if you ignore the politically popular, you can get a financial return on investment of 25 to 50% from energy saving investments. There are tens of billions of dollars spent each year on those investments, and word is spreading that you should ignore the political science/anti-science discussions and start saving lots of money by taking a sensible engineering/financial approach. One result is that in 2011-2012, while the US economy grew very slightly, its carbon emissions dropped 3.8%. Of that 3.8%, only 0.2% was from renewables. The other 3.6% was cost savings through energy efficiency and waste removal.
