But some people seem to be writing off everything Dyson says based upon his involvement with the pie-in-the-sky a href=”http://en.wikipedia.org/wiki/Project_Orion_%28nuclear_propulsion%29″Orion Project/a.br /br /There was nothing intrinsically wrong with the Orion concept. It might not be the best engine design we have (and would probably never be usable in our atmosphere) but it is a good idea.br /br /We should take our own advice, and stick to talking about our areas of expertise – leave the nuclear physics to the nuclear physicists ;).br /br /Generally, I imagine that the trees Dyson talks about are probably somewhere in our future – the question is whether the trees would come quick enough to stop problems if we just go on with business as usual.br /br /There is no reason not to pursue ideas like this – all ideas should be pursued to some degree. The danger lies in reliance upon one solution alone.
