What are you favorites about it? I know they have great power:weight, but don't they have fundamental shortfalls in pollutants/emissions and (strangely, considering the weight advantage) fuel economy? How would a Wankel that only had to do recharging (fixed gear, etc) serve in that fashion? A scaled down rotary that was portable might be a good "oh shit I ran out of charge" portable recharger, but then again, a fuel cell might be better for that.
