Thorium-based reactors – the “green” nuclear energy?

Thorium-based reactors – the “green” nuclear energy?

nuclearDo you know why we use uranium-based nuclear reactors? Yes, those dirty catastrophe-in-waiting plutonium-breeding waste-generating answers to today’s energy problems. Apparently, it’s precisely because they are a source of weapons-grade plutonium; back in 1965, the cold war was a factor in favouring the dirty tech over the clean one.

According to this Wired article, what we should have chosen was thorium-based reactors. They’re cheaper, they’re cleaner and they produce much less nuclear waste, which gets neutralized within about 300 years, as opposed to thousands of years for current reactor by-products.

I recommend you go read that article. For extra brownie points, have a look at this video; it’s a 16-minutes mash-up of several Google Tech talks about generating thorium-based energy.

We went and fought in World War III

We went and fought in World War III

soldierBack in the days of  the Cold War, we though the third great world confrontation was months, if not days ahead. We had a visceral fear of the Nuclear Holocaust, with all that entailed – the millions of deaths, the fallout, the radiation poisoning, the endless nuclear winter… A whole generation grew up taught to think in terms of us and them, fed on fear and propaganda, but mostly fear. We had the Berlin crisis and the Cuban missile crisis. We had the standoffs, the nuclear tests, the war games and the wars-by-proxy. We even had Comrade Krushchev telling the West quite literally “we will bury you”. The year was 1956. People were listening to Elvis and building fallout shelters in the backyard.

But the years went by, and crisis after crisis was averted by means of diplomacy and concessions on either side. Leaders came and went, but the doctrine remained the same. Arm yourself more than the other guy. Talk tough. Make a show of strength. DO NOT USE IT. It kept on going for 40+ years, right until the Berlin wall collapsed, taking with it an ideology and a way of life that dominated the XXth century. There were, of course, several occasions where war was narrowly averted – for instance this was one of them. But the thing is, it didn’t happen, and that is probably why today we are alive and well and able to click our way around the Internet, instead of scavenging for tins in the ruins of the Western civilization.

What I belatedly came to realise is that World War III did actually happen. In the military High Commands of NATO and the Warsaw Pact, on the boards – and later the computer screens – of intelligence analysts, in the nightmares of world leaders, World War III happened over and over again. And no matter where it played, no matter how it started, it always ended the same way. Nobody won.

That is why, in this nuclear age, the era of the great war has passed. Never again will we see tens of millions of soldiers marching across the world to re-enact the clash of the Titans. The political leadership of any faction, group or country may still be use the Cold War rhetoric – indeed, North Korea still does it to this day – but they will always stop short of action. That is why I am not concerned, for instance, about Iran’s nuclear ambitions. Oh, they might huff and puff about the great Iranian nation, but the most a nuclear Iran can hope to get out of an alleged military nuclear program is a stronger position at the bargaining table.

This does not mean we saw the end of wars. There will still be skirmishes, thawing conflicts, African civil wars, nationalist guerrillas, jihadist terrorists and Somali pirates, and many more. Plenty of opportunities to field test the new generation of weapons and to let the new recruits cut their teeth on a real theatre of confrontation. There won’t be peace in my lifetime, no matter how hard we may wish for it.

Still, one can always hope.

Happy Stanislav Petrov Day!

Happy Stanislav Petrov Day!

Stanislav_Petrov1On September 26th, 1983, Lieutenant Colonel Stanislav Petrov of the Soviet Defence Air Forces was in charge of observing the satellite early-warning systems at Serpukhov-15 bunker near Moscow. When the computer malfunctioned, erroneously signaling a nuclear missile launch from the U.S., this man went against Soviet military protocol and did not retaliate, preventing thus the outburst of the 3rd World War – which, if we consider the number of nukes each side had, would have been a very short war indeed.

His commanders repaid him by sending him into early retirement, on a meager military pension. His act remained unknown until 1998, when a book written by one of the officers present at the bunker that night recalled how the actions of this man prevented a catastrophic confrontation between the U.S. and the U.S.S.R.

This is what a true hero looks like.

Update: His heroism was eventually recognized, and in 2004 he was awarded  world citizenship – along with a substantial prize – by the Association of World Citizens, a San-Francisco based organization.
