This air-powered bike sounds like exactly what I have been envisioning for a decade and would very much like to see your idea becoming a working 'production' reality soon. I had-perhaps somewhat unrealistic-visions of a pedal-powered cycle (aided with helium inflated skids/pontoons) and have always been a dreamer of anti-fossil fuel propulsion means. Good luck and keep up the steemin. Have to add that, after 40 years of continuous cannabis consumption-whilst I will not criticize anyone for using it-I have now found the more pleasing/less harmful alternative in the form of cannabis capsules which we-in South Africa-are now able to use legally. They do provide the much needed therapy and medication for my physio ailments, as well as for my psychological problems, whilst not giving the 'stoned' effect. (I know, the rads are no doubt saying; "So then what's the point?" Well, after 40 years of heavy usage, I have realized that, while helping with the before-mentioned problems, it does have a certain detrimental effect on some of the psycho. results as well. I find I now sleep/rest twice as well, and am not prone to any of those old paranoid, and occasional guilt trips neither. I know most users do nor suffer any guilt or paranoia but, for me, 40 years has been more than enough. I believe it was provided for our constructive use , to be used with skill and discernment. But, like I said, please do not take my new take on the issue as any type of attack on you guys.I was there for 40 years and I love you all still as much! Ozz out.
