Eco-sham classroom too cold to use February 25, 2011

Yes, it is rather dreary in London……

Eco-campaigners who built a classroom powered by the sun believed they were paving the way for the future.

Instead they have been taught a valuable lesson – there is not enough sun in North London to sufficiently heat their building.

The much feted zero-carbon Living Ark classroom was opened three months ago to great fanfare.

It boasts laudable green credentials and is made from sustainable wood, sheep’s wool and soil. The roof is made of mud and grass and it has its own ‘rain pod’ and solar panels.

But there is snag – its solar panels only provide enough energy to power a few lightbulbs.

As a result the classroom is bitterly cold and uninhabitable for lessons.

Parents have branded it ‘useless’, an ‘expensive piece of wood’ and a ‘great idea for the Caribbean’.

There are many, hopefully well intentioned folks, who would like to strongly encourage, even force, the rest of us to use unproven technologies to replace evil, evil fossil fuels.  Unfortunately, most of these alternative energy sources have massive problems that have prevented their widespread use – after all, in a free market, if there were truly a way to power our homes and cars and everything else in a manner that was completely pristine, would it not have taken off by now?  Solar cells, wind, all the favored forms of ‘alternative energy’ have serious issues of scalability and availability – capacity time.  Your average wind generator is “up,” producing power, less than 1/3 the time.  Depending on the location, solar cells will work between 10 and 45% of the time, and they never work at night, so you have to have a massive cache of batteries, full of very harmful and dangerous heavy metals, in order to store power for use when the sun isn’t out.  And they just don’t scale very well – we’d have to wallpaper Arizona from end to end to even produce a portion of our nation’s electricity supply from solar.  So while the intentions may be great, neither of the two most cherished forms of alternative energy so loved by environmentalists has the potential to be more than niche players.  But if folks want to try to use these things – great.  Just don’t make up false government mandates that will lead to the vast majority of us shivering in the dark.
