Air-powered cars..... attn PV if he's still around.
So, what would be the size and weight of a spring that would be needed to propel a one ton car 50 miles? Similarly, an air tank? Jordan |

Jordan fired this volley in news:xQdRo.5880$MF5.3599
@viwinnwfe02.internal.bigpond.com: So, what would be the size and weight of a spring that would be needed to propel a one ton car 50 miles? Well... in THAT technology it was only 20lb., or so. In ours, it would be MUCH bigger. OTOH... most cars don't weigh a ton anymore, unless my M-I-L is riding in the back. LLoyd |

. 3.70...

Even small cars weigh more than a ton -- I think my Honda Fit is over 2500#. Miata's may be under a ton, but you can start those cars with 8 D-cell batteries, iiuc.... The SmartCar is under 2,000# and proly the TaTa, but I think barely a handful of cars sold in Merka are under 2,000#. To the other query, these air tanks appear to be the size of a full size oxygen tank, with two or three lying under the frame, compressed to 4,000 psi. Dats a lot of psi, and mebbe even higher psi can be achieved. -- EA LLoyd |

Jordan Unanswerable, as is how many horsepower-hours are needed to propel said one-ton car 50 miles. The mass of the car is only relevant if the car changes elevation in that 50 miles. Rolling friction, wind resistance, speed and how much braking is done during the trip are also significant variables. |

sometimes I think there are about 200 people in all of usenet... Before Comcast ran cable through my neck of the woods, I was on dialup. I was talking to my ISP years ago, trying to resolve an issue with Usenet. He told me that out of all his hundreds of customers, I was the only one using Usenet. Maybe he was trying to snow me some, but I have yet to mention newsgroups to anyone that had any idea what I'm talking about. So we're certainly a minority of internet users as a whole! Jon |
