This is a few months old but it does mark good progress for eventually developing the capability of space exploration without having to take rocket fuel along for the ride.
If the efficacy of the drive is confirmed, the implications for space travel are profound. It seems that another technology from Star Trek may be about to become reality,.
This is how you buy the government of the United States. You say, “$721 million is a lot of money.” I respond it is a cost of business item. Fossil fuel companies operating in the U.S. and Canada made $271 billion dollars in profit in 2012, while continuing to receive billions in subsidies. As of April 14, 2014 , according to Mother Jones, “Taxpayers currently subsidize the oil industry by as much as $4.8 billion a year, with about half of that going to the big five oil companies—ExxonMobil, Shell, Chevron, BP, and ConocoPhillips.” So let me see. They spent $721 million to buy the government; they got $4.8 billion in subsidies. And the conclusion is: You and I paid the fossil fuel companies through subsidies, money which they metaphorically in turn used to buy the government so that it operates responsive to their interests, rather than the interests of the citizens who paid the taxes. What a deal.
The soap is enriched with a special secret mixture of local herbs and leaves a scent that repels mosquitoes on the skin. In addition waste water products from the soap contain substances that prevent the development of mosquito larvae. This is important, since poor sanitation is one of the main factors in the spread of malaria. Read more.
I am troubled by the platitudes and ignorance surrounding the murder of two New York police officers. I am a son of New York and my uncle was a member of the Nassau County police force back in the day when non-judicial punishment kept people out of jail and got them back on track with tough love.
The death of these two officers is the equivalent of the canary in the coal mine dying. They have died because the USA is on the verge of a revolution. Apart from concentrated wealth, loss of faith in government, and tens of millions of unemployed college graduates, we have an unemployment rate closer to 22.4% (see ShadowStats), with 22 veterans committing suicide every single day.
It is driving the rightist prohibitionists crazy that none of the dire predictions they made about ending Marijuana prohibition have come to pass. In fact the outcomes have been the exact opposite to what they said would happen. So now they are trying to get the conservative majority on the Supreme Court to reverse what the people themselves voted for. It is not clear how this will play out but it has the potential to create a massive crisis of governance.
The next big disruption may well be semiconductor cooling. It's been around for a hundred years in little Peltier devices that power some little refrigerated coolers and cool computer chips, but now startup Phononic has scaled it up and made it more efficient. They are making thermoelectric heat pumps that can power refrigerators and other devices with no moving parts, no toxic refrigerants, and finally, no noise.
