Free energy anyone?
Whoever heard of anything for free? Well, let us see. As hunter gatherers, we had everything for free, it was all just there and we either hunted or gathered it. As for housing, well, there were caves or trees to provide shelter, in the worst case scenario, we could make tools to cut the wood from the trees to make things. Simple, was it not? When man invented the concept of money, then things changed. “Ah, yes, let me dig up this black liquid from the ground and sell it to you so you can burn it. No, don't worry, the free source of energy doesn't exist.”
We fell for this, and thought burning oil (gas, coal or of course wood before that) was the best thing man ever could do, we forgot all about the most obvious, the big yellow dot staring down at us, yes the sun's energy.
Yes, silicon's efficiency at turning the sun's rays into electricity is not so high, but the sun shines freely all day long! Perhaps, the key is to make politicians see this, just as once Winston Churchill saw the advantage of oil over coal and therefore his ships ran faster than the German ones, we should open the eyes of the next American president. Hey, Mr/Ms Mc ClinOba, did you know you could make a difference to the world, but in a good way this time? How is about you stop supporting your oil companies at any cost? There is plenty of energy for everyone, let us use that, and you can support other businesses in your country. Let us face it, your economy could hardly get worse than it is today.
In a more serious and calmer tone, one must insist on the sun's energy becoming a serious player. One knows of climate change, the damage digging up oil/gas/coal does to our landscapes, not to mention the problems this causes politically the world over. There are other resources we cannot replace, such as water, iron or aluminium, then why not try to make our own lives easier and use energy, which is there for everyone all the time? We have the technology to do this, be it using silicone or carbon panel, or simply by heating water or air directly by the sun.
Recently, an article in the Economist magazine (March 8th 2008 – Technology quarterly) caught my eye: “A bag full of sunshine”. Attach solar cells to LED, and voila, you capture light in the day to release at night, and a couple of nifty companies have managed to incorporate these into all kinds of soft materials. Could it be easier? How does this not capture the imagination?
How can one make a difference? Simple, when opportunity arises, switch to solar – through choosing the right electricity company on the grid, adding panels to the roof of one's house/block of flats, and spreading the word.
