I have done most of my Doing already-I'm in my 60's now and I'll leave that "Doing"for you kids for a while. I may have to come back and try straightening you all out but until then.............
I have been researching alternative fuels and technology since it first interested me in the 50's while I was in school.
Except for the more complex control systems that add maybe 10 to 15% in range and controllability the current technology isn't all that far advanced from the 1970s electric golf and shop carts.
They ran cars on alcohol during WW2. Some even ran on woodsmoke!
When something comes along that satisfies my needs and at 6' 3" 235 it will be larger than the shoeboxes that they will sell at first, I'll consider buying it.
Until then I will keep track of what they are doing and what they can bring to market.
I'll keep driving other peoples castoffs and not waste the energy required to build a new car just for me so I can save a little energy and feel really good about it! (Prius owners can apply here for that credit)
So now I am going to climb down from my soapbox - have a nice day!
