I Like Trains. Especially When They're Roller Coasters.

I could not be more excited if someone had told me that they were considering building a helter skelter between my flat and the street. I would be a bit more excited - say, if someone actually had built a helter skelter between my flat and the street - but this incredible innovation is in Japan.

But with good reason.

Tohoku during the 2011 tsunami.

Following the devastation caused by the tsunami last year, a company called Senyo Kogyo (which designs rollercoasters and other amusement park rides) along with a team from Tokyo University's Institute of Industrial Science have designed the Eco-Ride, a train that will use largely its own inertia to move.

It will have no engine and be very light; gravity will do most of the work, so what little energy is required will cause next to environmentally unfriendly emissions. Its speed is controlled  by 'vertical curves' in the tracks and should be able to travel at up to sixty kilometres per hour.

Numerous areas of Japan are already interested in installing Eco-Ride trains and it is hoped that they will expand to be used all over, to get around cities and towns but also by big business and sprawling university campuses that take a lot of time to walk around between, for instances, important meetings or lectures. The first train is expected to be built in 2014. It is due to be built in Tohoku, which, aside from being necessary to help survivors of the flood get around the ruined landscape, is said to be the perfect environment for Eco-Ride trains because of the slope between the relocated accommodation on the high ground in comparison to the businesses at the lower sea level.

Alight, these people have had their home washed away by furious, broiling sea water, but very soon they will be able to get a roller coaster to work.

With all due respect, sympathy and wishes for a quick recovery from the tragedy ... I am a little bit jealous...

The New Contender in the Energy Market: Air.

Evironmentally, you really can't win. Statistically, I am kind of winning; my life is quite environmentally friendly - I am frugal with electricity, I walk most places and get the bus to all other places, I have a Friends of the Earth hoodie - but that it because I am a poor student and I live in expensive London and Tim Minchin was at the Friends of the Earth gig, so I don't really have much of a choice in these matters. For people who can afford choice, you're pretty much damned if you do and damned if you don't. Using technology is necessary, but bad. Driving a normal is bad, but driving an electric car makes you a pretentious prick. Also, electricity is bad. And electric cars are ugly as fuck.

But this could be about to change. The G-Wiz will still be hideous and you will still look like a douche if you even consider getting into one. But it won't be your only option.

Because of these dudes. These wonderful nerds - and I do love nerds - at Air Fuel Synthesis are making fuel out of air.

Out. Of. Air.

Earlier on in October 2012, they revealed the first successful demonstration of their techniques, showing how carbon, hydrogen and oxygen can be taken from carbon dioxide and water in the air to be converted first into methanol and then into petrol.

They didn't even have to go into any more detail to blow my mind. The idea has been around since the oil crisis of the 1970s, but it still feels a bit like science fiction to me. So they offer this helpful graphic to explain to nerd-groupies like me who have no real nerd credentials aside from enthusiam:

The problem with it at the moment is the energy efficiency of the process. Obviously, it would not be environmentally beneficial if more energy was put into it than is created by it, and this is still being smoothed out, but that makes it no less cool.

With funding, it will get there. Eventually. There are huge plans for the technology which could revolutionise the way that energy is created. The maths for its development on a much larger scale is already sorted out and, once it has some firmer backing from governments, it is hoped that it will be a contender against oil in the energy market.

Hopefully it won't make the same mistake as some of the other companies that have tried to save the world and will offer us some technology that isn't too ugly to touch.
