"... Hunter described a design for a 1.1-kilometre-long gun that he says could launch 450-kilogram payloads at 6 kilometres per second. A small rocket engine would then boost the projectile into low-Earth orbit.
Huge g-forces

While humans would clearly be killed and conventional satellites crushed by the gun's huge g-forces, it could lift robust payloads such as rocket fuel. Finding cheap ways to transport fuel into space will lower the cost of keeping the International Space Station in orbit, and in future it may be needed to supply a crewed mission to Mars.

The gun would cost $500 million to build, says Hunter, but individual launch costs would be lower than current methods. "We think it's at least a factor of 10 cheaper than anything else," he says."

"If other urban areas have a similar share of uncatalogued emissions, then these unknown urban sources would account for 7 to 15 per cent of global methane emissions from human activity.

This extra methane may result from higher than expected leakage from landfills, sewage treatment plants or natural gas pipelines, or it could be natural seepage from oil wells or other geologic sources, the researchers say." Or farting, maybe? Damn you, vegetarians, with your save-the-world rhetoric and noble self-sacrifice! You've doomed us all!

"Now that’s as classic as the New Great Game in Eurasia can get. There’s NATO vs. the SCO. With either IPI or TAPI, Turkmenistan wins. With either IPI or TAPI, Russia loses. With either IPI or TAPI, Pakistan wins. With TAPI, Iran loses. With IPI, Afghanistan loses. In the end, however, as in any game of high stakes Pipelineistan poker, it all comes down to the top two global players. Ladies and gentlemen, place your bets: will the winner be Washington or Beijing? " Wanna know where the next wars are going to happen? Read this.

"When natural gas is drilled from underground reservoirs it is at far too high a pressure to be used safely in homes. "It would just blow up your gas cooker," Mercer said. Instead, the pressure must be released at hundreds of sites across the supply network known as letdown stations. Currently, the energy contained in this released pressure is wasted. The new technology aims to capture it to generate electricity."

"... the gas is used in tiny quantities -- but molecule-for-molecule, NF3 is about 17,000 times as potent as CO2 in warming up the atmosphere."

"We have seen the future of gas stations, and it’s very artistic. Now if only more buildings in Los Angeles looked like this…" That's ... erm ... interesting architecture?

"The discovery of a mysterious solid form of natural gas off the east coast of Canada could bring one of Earth's biggest untapped sources of energy a step closer to commercial use, according to scientists."

"...this is the first time the biodiversity of the animal communities living at these sites has been observed directly and thoroughly documented, providing the first discovery of cold seep communities in the entire southwest Pacific."

"Conventional wisdom suggests that the moon has seen no widespread volcanic activity for at least the last three billion years. Now, a fresh look at existing data points to much more recent release of lunar gasses." *Relatively* recent, that is.

"How could you possibly study the interior of a giant planet orbiting another star? Especially when that planet is so drowned in its star’s light that we can’t even see it?"
