Solar Energy Generation

There is no doubt that life is the transformation of solar energy, at its core, but this could soon be taking on a new meaning if we (the world) don’t get our act together over climate change. Obviously finding an alternative clean form of energy is key to our future, of which there are many possibilities – solar, wind, tidal, etc. Back in 1999 I designed and built a prototype wind turbine for individual use as part of a project for one of the A-Levels I was studying for at the time. Whilst this was never intended to change the world (!) I learned quite a bit about the technologies involved and their limitations, mainly being around conversion efficiency. Now seven years down the line with the problem becoming more acute in the public eye perhaps finally people are starting to take note…

As the very cinematic ad. says 970 trillion kWh of energy falls from the sun every day, isn’t it about time we put it to use?

Did you know? I always imagined that the Korean alphabet (한글, Hangul) contained thousands of crazy characters like Chinese and Japanese, making it nearly impossible for the simple western mind to understand! In fact it only has 24!

King Sejong and the scholars of the Chiphyonjon, creators of the Korean alphabet, considered human sounds as being more than mere physical phenomena. They assumed that an invisible yet more powerful principle was the controlling force behind these phenomena. They adhered to the principle that human sounds and all universal phenomena are all based on yin-yang (positive-negative) and ohaeng (the five primary elements: metal, wood, water, fire and earth). Hence, they thought it natural that there be a common link between sounds and the changing of the seasons and between sounds and music.”

이것은 쉬워요 – easy huh?!

And one last thing… The new version of iTunes which was released earlier this week is great! I especially love the Cover Flow view which allows you to visually browse through your music collection by its album art – very cool, very Apple!

Have a great weekend! 주말 잘 보내세요!

    I don't exactly remember the output of my turbine, but it was enough to trickle-charge a car battery. The embarrassing thing about it is that you can still find a picture of it on my former schools website:

    Please bear in mind this was May 2001!!

    Thanks for the link BTW… looks like an interesting idea.

    I'm all for home generated electricity, especially if it was reasonably cheap and easy to construct something yourself. What was the power output of your turbine, and did it have an inverter for conversion to AC?
    I think it's crazy that we stopped using windmills and watermills so much.
