Well...in that case, my advice would be an awful lot of budgeting -- energy, weight, money, time, and everything else. Start with the Stella as an assumption of a best-case scenario. You should be able to find or guess all the important facts. How much does it weigh? How much would it cost to build an one-off carbon fiber structure of that weight? If you haven't built anything with carbon fiber, call up a shop that specializes in it and ask them for a ballpark figure of what they'd charge you and run with that number. Yes, you'd be able to do it cheaper...but only assuming you do it perfect the first time, so run with their number. The surface area of the panels should be known. Use that figure to spec out the highest-output lightest-weight moldable panels you can find...and don't be surprised when _that_ cost is close to if not more than what your mortgage statement reads. You've got weight and energy in; from there, you can calculate power requirements and how close the panels come to meeting them. For the generation, take the standard figures for rooftop solar, make sure that the installation angle of the calculator you use is horizontal, and knock off at least another 10% due to even worse geometry and the like. At this point, you're already looking at a project that costs six figures easily and likely, even on paper, doesn't go as fast nor as far as you want it to. So, if you want to keep pursuing the project, work on those bits. Once you've got that much solved, then you're ready to start moving on to more mundane things like motors and batteries and the like. b& _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
