I am an American designer and inventor. I love our country and want to do my part to help us stay strong and free. I am here to encourage you to do the same.

This was good advice then. It is good advice now. Especially when 3 out of 4 gallons of fuel we use for transportation is imported. Living beyond our means is making us poor and them rich.

I have suggested a variation of Mr. Franklin’s advice:

“To live better on less energy”

Now THIS is what I'm talking about! Thank you Craig for your inspiring competition; may it lead to great things.

Hey Craig, You mean this guy: "Sam Whittingham defends 82 mph world record for fastest human powered bicycle"? I concur with your analysis. His vehicle is impractical and perhaps dangerous (too low) for a daily commute on the highway. However, it does set an upper bar for what a human is capable of. I see better, not as going faster, but more comfortably. Also, the method they use to cut through the air is called laminar flow (probably spelled it wrong). It is dependent on some very ideal conditions. I'm using a completely different approach to aim at a much lower goal 100 km/h (62 MPH). Basically I’m trying to get extended range out of a battery dependent system. My thought was if I take more frontal area (vehicle height) and more weight (batteries and motor) is there a way to maintain speed using my body, and having the electrical system engaged minimally? That is where you all taught me that there may be a better way to approach the problem. What if the electrical system processed the air the vehicle was attempting to push through? Would it be enough to tip the scale in my favor at higher speeds? Perhaps you are correct about all of this. But I'm not willing to die in an armchair years from now wondering "what if?" Thank you for your genuine concern and design experience. You are right; there is not enough room to put everything in these boxes. Have you considered Golf ball aerodynamics? CM

Crimson: Please keep in mind that it is all about power. How fast can you make a vehicle go? If you are an animal, like Sam Worthington,you can go 82 mpg briefly. If you make yourself real tiny... real hot and sweaty... real uncomfortable like Sam you can do 54 mph for an hour. Are you gonna go to work in those conditions? Besides,in a tiny vehicle like that you are very likely to be run over and squished by somebody in a car or truck. You gotta be bigger to be seen so you can stay alive. You need more power, too. I don't think you or I or almost anybody has what it takes to go highway speeds for any useful time. In my contests of the 1980s, we discovered you needed about 3 hp - and that was in an era when highway speeds were 55 mph.
