I just came across something I think is utterly fascinating- but it has nothing to do with Parallax or microprocessors- so moderators please delete if you think appropriate!(or inappriate).
I was watching a video about Formula-E motor racing. I have to say it doesn't do much for me- much prefer formula 1- anyway it turns out that in line with the 'eco friendly' message they are (trying) to promote, they charge their fancy batteries from a diesel engine generator!!
What a diesel??
Yes a diesel driven from a new fuel called 'Aquafuel'. Why Aquafuel?
Well it produces almost NO pollution. What's more its a waste product!
Too good to be true? How can this be?
Its over my head, but fortunately they produce a pdf document explaining everything and it makes very interesting reading.
