Science

Back to the windmill

Bernard Dixon

NASA — the US National Aeronautics and Space Administration — is backing a crash programme on wind power. Repeat, the proud body responsible for the Apollo programme that put men on the Moon is now conducting research into windmills. It's true, they're highly sophisticated, terrifically efficient windmills, built using the verylatest scientific knowledge and newest techniques and materials. But they are essentially windmills. From exploring the universe and the frontiers of knowledge, NASA has thus turned to harnessing the elements by using one of the most venerable of methods.

For me, this strange circumstance crystallises the remarkable change that has come upon the world in very recent times, a change of which the current 'energy crisis ' is in part a symptom. This concerns the ways in which we should exploit technology in the service of man. And what has begun to alter — for both the providers and customers of technology — is fundamental thinking about the rate, style, and content of technological development. Instead of technocratic utopianism, which uncritically welcomed and applauded all new breakthroughs, we now have a state of modified rapture. Technology, we h4ve realised, must be developed and deployed according to what has emerged as a new set of sound and prudent ground rules.

A measure of the rapidity of recent change is the fact that these principles, perhaps in somewhat extreme form, are those that have been summarised by the term alternative technology, which used to be considered highly unorthodox if not totally outty. Among the central tenets are the need to conserve resources, and not mortgage the future for unborn generations by depleting irreplaceable materials,
