Researchers Try To "Close the Nutrient Cycle" Through Better Waste Recycling 112

An anonymous reader writes "Converting human waste into usable fertilizer may become the next important development in sustainable living. 'Most conventional farms invest in synthetic fertilizer, which requires energy to produce and is associated with many environmental problems of its own. But by separating out human urine before it gets to the wastewater plant, Rich Earth cofounder Kim Nace says they can turn it into a robust fertilizer alternative: a "local, accessible, free, sanitary source of nitrogen and phosphorous."'"

Sound System Simulates the Roar of a Rocket Launch 113

retroworks writes "Located in Noordwijk, Netherlands, and part of ESA's ESTEDC Test Center, is the Large European Acoustic Facility (LEAF), a sound amplification system 'powerful enough to kill a human being.' LEAF is capable of generating more than 154 decibels, the sound equivalent to standing next to several jets taking off. It is used to blast satellites and spacecraft with sound. Large horns are housed in a sound-proofed room that is 16.4meters tall. One wall of horns stands 11 m wide by 9 m deep and 16.4 m high. LEAF requires all the doors to be closed, operating in steel-reinforced concrete walls to contain the noise. The walls are coated with an epoxy resin to reflect noise, producing a uniform sound field within the chamber."

Quadrupling is a 400% increase that would take 40 years at 10% via simple math, and even then it would be right.

No. Much shorter.

Simple math says:
(1+10/100)^y = 4 =>
log (1.10^y) = log(4) =>
y * log(1.10) = log(4) =>
y = log(4) / log(1.10) = 14.54 .
After 14.54 years you quadruple; after 15 years you would have a 418% increase.
Didn't they teach you exponentials and logarithmics in high school?

In other news, the UK PM Sir Mortimer Chris (played by David Cameron) said:
"It's all because of the invisible leprechauns. It's true, because I saw it in a film. We have to be much tougher on everything and everybody in order to eradicate this terrible pest. The Snooper's Charter is just the beginning; I'm now working on the draft Wear Your Underpants On The Outside For Hygiene Law (WYUOTOFH law).

Most of my cabinet ministers have agreed with me, and those who haven't (because the leprechauns subverted them) have agreed to be publicly crucified in Wembley stadium to atone for their weirdness and sins.

I have instructed our nuclear submarines to go to code Red. Death to leprechauns. God will save us!"

You're doing it wrong.. Of course the car will only be able to drive *as long as it keeps receiving the official "you're allowed" signal*.

Reminds me of FlexLM license manager program in the '90s. Look at it wrong, and it decides you're trying to tamper with its functions, and kills all legitimate paid for use of the licensed program.

Edward Snowden and the Death of Nuance 388

Trailrunner7 writes "As the noise and drama surrounding the NSA surveillance leaks and its central character, Edward Snowden, have continued to grow in the last few months, many people and organizations involved in the story have taken great pains to line up on either side of the traitor/hero line regarding Snowden's actions. While the story has continued to evolve and become increasingly complex, the opinions and rhetoric on either side has only grown more strident and inflexible, leaving no room for nuanced opinions or the possibility that Snowden perhaps is neither a traitor nor a hero but something else entirely."

There was IIRC one senator or somebody who called for W. Bush to be impeached; I think his name was Kuchinich(sp?). It was on the news (in Europe).
I was a bit surprised that there didn't seem to be any actual impeachment process, almost like
"yeah, but Congress is not *really* going to impeach the president for starting a war--that was just for laughs! silly rabbit! Impeachment is only for shoving your <[censored]> in immoral places"
