Green tech through the ages

I'm getting old... can't really remember whether I wrote about it. Oh well, the article and photos caught my eye. Manchester International Festival is looking for green technologies that are feasible, have impact and commercial potential. Actually, green tech has been around since the turn of the last century..... are you impressed? I am, but a little annoyed that things are only beginning to speed up at the turn of THIS century!!!
