Things seem to be heating up in both Nigeria and the Middle East so fuel is liable to spike or become rationed in the next few months, or sooner. I remember my first year of driving, 1973. Suddenly, there were long lines for rationed amounts and you could only buy gas every other day. This wasn't really that long ago but many have forgotten how paralyzed we are in the US without gasoline. I expect one reason early adopters will choose the Photon S3 is the security of fuel supply since you can easily manufacture your own with increasingly cost-effective solar panels, wind turbines, and micro-hydroelectric plants.
Spring will bring wind in the face as we test, test, test the design. Stay tuned, we shall prevail.
