While blogging and thinking about those electric scooters I’ve finally thought my way back to the power source (again). I’m still terribly angry at the present government for going back on the whole coal for energy thing but that’s a separate rant. So what are we supposed to do?! The effective energy sources destroy the planet (or us) and the environmentally good ones are not yet available in abundance and it is doubtful they will ever be.
Some say the answer is in solar panelling the world or space, having a wind-farm on every hill, taking geothermal energy and having tidal generators for every stretch of coastline suitable. I’m not really opposed to that but even that is probably not enough to feed the energy needs and the future energy needs of India, China and others. I can also fully understand people that don’t want a rotor looming over their back garden. So again what is the answer?
We all -deep down- know what the answer is. NO! It’s not nuclear reactors! God forbid! The radioactive waste on those has a half life of about 10,000 years. We haven’t even been able to come up with a warning sign that will last that amount of time (remember the pyramids are “only” 4000 years old). I think I’ll take coal any day compared to that. No, the answer is something we’ve all heard before but have chosen to ignore. It’s the stuff mentioned in the title. What I’m talking about is nuclear fusion.
Fusion is the only power source known to mankind that can supply more power than atomic reactors (thereby enough to power all of humanity) with producing a minimum of radioactive output (a minuscule amount compared to your average nuclear plant) or any output apart from energy for that matter. As I said we’ve all heard of it but why hasn’t everyone got one in their back yards? Well…. that’s because we can’t build them yet. We don’t even know if we can. The Europeans have come together to build the biggest Tokamak type reactor ever in France called the ITER (there’s also the Stellerator type fusion reactor like the Wendelstein 7-X being built in Germany which is a different concept and cheaper). It’s the first time there’s an attempt to build a fusion reactor that can produce more electricity than it consumes. i.e. it would be the first reactor that can be seen as a proper power generating station.
But remember that we don’t really know if the scientists and builders can do it. The whole project is currently budgeted for 5 billion US$. They will probably end up paying $6-7 billion. Expensive …not?! We’re building something we don’t even know will work but sinking all this money into it???!!!! Most people don’t even know that it is being built!
Well, I think we’re not spending enough and not enough buy a long shot. If ITER (International Thermonuclear Experimental Reactor) succeeds humanity will probably have solved all energy problems we ever had and could have. Within this century we could switch off almost all of our bad energy sources and wouldn’t even have to build any wind farms or solar whatevers. This would revolutionise the world energy economy. Fusion power is so cheap it would obliterate your energy bill. So why are we spending only $5-7 billion? If this is as good as it gets why aren’t we spending more? America pays $500+ billion a year in oil imports and $230 billion in electrical bills. A nuclear (fission) reactor costs about the same as the fusion reactor. Are you doing the maths?
There’s a lot of negative controversy around the ITER too. Green parties and Greenpeace are complaining that the funding is taking away from funding alternative energies. That fusion reactors will probably not be operative before 2050. Sorry but how shortsighted is that? Alternative energies are needed and good but we all know that they cannot ever produce enough power to feed the world with power. Humanity needs fusion power or something new we haven’t invented yet. We cannot stop researching fusion just to spend more money on the wrong type of power generation and by that I mean anything non fusion. Green parties and environmentally friendly organisations should concentrate on supporting fusion strongly AND pushing for alternative sources in the mean time. By bickering over this all energy sources loose.
Humanity will need more power in the future not less. Even if we start consuming less. We will probably see a day when there are 10-14 billion people living on this planet. They all want to be warm, mobile and watch TV. They will still want to travel and do things. Fusion with its promise of the ideal power source is really the answer. I discuss electric cars, others are fans of hydrogen (which I believe will be the answer for trucks, buses, heavy machinery, air travel and not for personal travel – that will be battery-electric). Both need a clean energy source to have any positive impact on the world.We will not get that without the fusion reactor.
So my plea is to have a closer look at fusion and support it as much as possible. Maybe NZ should actively allow fusion reactors to be built and give TAX cutbacks for doing so. That might give the power companies something to aim for. But even if not that it would certainly create discussion and publicity for the technology. Who knows maybe the US Navy will go fusion and then they could come and visit us! Go out and do some research like I did and see for yourself. The links above are a good starting point.
