"Teachers increasingly tend to intervene in critical situations in a policing or disciplinary role. The human to human contact is lost.”
Such as fist-on-face human contact? I remember the good old day where the stronger pupils could make the weaker ones lives a living hell. Where will the next generation of middle-management come from if this natural human interaction is stopped?
Although the British isles saw great cultural changes during the Celtic, Roman, Saxon and Norman invasions, genetic studies show less dramatic shifts in population than some may imagine.
Essentially, the elites changed and imposed their culture. We Britons are still mainly from the same stock that originally colonised after the last ice age...
"It's all about radiation. Excessive neutron radiation causes fusion reactors (using current technology) to destroy themselves."
Maybe the hundreds of nuclear physicists who worked at/for JET and soon ITER know they are wasting their time... Or maybe your belief that the neutron issue is unsolvable isn't shared.
What reaction are you proposing to use? H3-H3? Can you elaborate on how you might achieve it?
Physics World (August 2007) did a nice debunking of this.
In summery:
The Deuterium-Tritium reaction is x100 faster than the Deuterium-Helium3...
If we assume a Tokomak reactor, two Deuterium atoms will fuse to form Tritium and a proton relatively rapidly, thus providing the fuel for the rapid Deuterium-Tritium reaction.
So the Deuterium-Helium3 might be cleaner, but how do you achieve it exclusively or even as the dominant process?
Or perhaps the even slower Helium3-Helium3. Not even ITER will generate the heat needed to break even on that, never mind commercial generation.
Inertia confinement perhaps? But with such a slow reaction what would the parameters of such a machine be?
So what is the point of mining the moon for Helium-3?
So BAE executives may face criminal charges in the US for complying with a contract negotiated and agreed between the UK and Saudi governments...
I am the only one who finds this situation outragous? If the US want to press charges, surely the right people are the UK and Saudi government officials who did the deal? Surely the primary target should be a certain good personal friend of a G.W. Bush who recieved the money (allegedly)...
