Well guys, it has been a couple week of fun but I am going to bow out of the discussion at this point since the technical questions seem to have reached a finish and cycled back to repeating the same. I'd encourage the 'technical' people to reach out through the website if you have some real questions that aren't answered in the thread - please don't bother with miles per gallon and MIPS/kW, they are irrelevant design features at this stage of development.
Feel free to join me in London at the DEVCON Conference the week of the 9th and the DCD Converged conference the 18th - 20th, I'll be on a panel discussion of this topic as well as presenting the project - I'm looking for a few good hecklers.
Andy, you seem to have a pretty good grasp on things - would be great to bump into you when I'm in the UK.
Thanks
