Found an interesting article on iafrica.com today about another project aimed at using kites to generate electricity. This concept is more of a merry-go-round with large kites tethered to spokes. Some prelminary trials have been done and a small test showed that it was possible to produce energy using this design. A team has been assembled and they will begin work on larger prototypes.

LET’S not beat about the bush here: unless we do something pretty damn dramatic to slow the pollution of our atmosphere, the world as we know it is going to change — and not for the better.
In fact, some scientists believe it’s already too late to halt the progress of global warming, citing the relentless consumption of fossil fuels, the melting of the ice caps and many other portents of disaster (for the sake of brevity and everyone’s mental equilibrium, we won’t go into the cavalier dismissal of the Kyoto Accord and other initiatives aimed at curbing the dreaded greenhouse effect).
Against that, we should be encouraged by the fact that scientists, engineers and assorted futurists are trying to avert the looming crisis with a host of strategies, including the development of safer and more affordable nuclear power (see “A new atomic age”, November issue) and proposals for the safe storage of nuclear waste — if there is such a thing.
Some of their ideas are workable only on the basis of hugely optimistic assumptions — for example, a sizeable proportion of the world’s motorists deciding to swop their muscular gas-guzzlers for wimpy fuel cell-powered vehicles costing three times as much — while others are characterised more by gee-whiz ingenuity than practicality.
Some of the more provocative ideas exist only in the form of outrageous concept drawings and small prototypes with cute names.
We’ve heard about wave power (actually, this is one of the few concepts with serious potential), geothermal power (again, quite effective, but not suitable for rolling out on a large scale), wind power (experimental wind-powered turbines are already doing their bit in South Africa), and many other strategies — including (as we recall from our recent Great South African Inventors Competition) at least three utterly foolproof designs for “free energy”.
Now meet a concept that must rank among the most original yet — kite power.
