Right Proper Steam Cycle.

I just had to share this as it is every Greenie Eco-Terrorists nightmare. Of course it had to be built by an Englishman and shows what can be done come some spare time and a shed. I love the station that he has built for it as well. The reference to HP rating is interesting as for example my Norton was rated at 3 1/2 HP for tax purposes to give some understanding of how far from reality some HP ratings can be.
I believe a cheese cutter and Mk. II Stadiums would be mandatory wear upon this marvel.

The other extreme...

So a bit faster than a Hyabusa with cooler sound then but not as fast as a Kawasaki Ninja H2? I have the greatest of admiration for those that push the boundaries especially when they make it themselves.
