Submission + - Scientists have moved a step closer to achieving sustainable nuclear fusion (theguardian.com)

Kkloe writes: US researchers have achieved a world first in an ambitious experiment that aims to recreate the conditions at the heart of the sun and pave the way for nuclear fusion reactors. The scientists generated more energy from fusion reactions than they put into the nuclear fuel, in a small but crucial step along the road to harnessing fusion power. The ultimate goal – to produce more energy than the whole experiment consumes – remains a long way off, but the feat has nonetheless raised hopes that after decades of setbacks, firm progress is finally being made.

In nuclear physics, nuclear fusion is a nuclear reaction in which two or more atomic nuclei collide at a very high speed and join to form a new type of atomic nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to photons (energy). Fusion is the process that powers active or "main sequence" stars. -Wiki

well for motorways because its probably cheaper to block it one way than both, say it costs 1000 to set up a concrete wall for blocking sound from both sides, but it costs 650 with this new type of wall, but doing it both sides would cost 1200, so its cheaper one way than two airplanes, did it even say where?, no, it could be around the engines or from the outside to the inside, was it that hard to understand?

what?, do you even know how to make a analogy that has to do with the topic? it would be more like you advertise free lunch, people eat the free lunch, then you sell the information about the lunch, like did the person like it, how long did it take to eat it, did the person eat all, did he prefer lunch option a or b etc...
