need spring-energy-storage mechanism
Anyone that has ever tensioned a garage door spring, intended to
assist lifting a weight of at most 50-100 pounds a few feet, and saw the spring that takes . . . wouldn't be seriously considering a spring - just too damn heavy and large to get its own weight up the hill. very excellent point. one which I figured out after some googleing, and mentioned in the new thread. Your example is much more intuitively clear and obvious. Kudos for that. only slightly valuable cargo, well, that's what it is. videlicet, people can make substitutions for it. and now are, at a price that's lower than what I can produce mine for, unless i can do it EXTREMELY cheaply. wouldn't demand a high tech solution like regenerative brake bicycles, is that high-tech to you? Eaton/Peterbilt does use hydraulic/ pneumatic storage of regenerated-braking-energy, RIGHT NOW for dumptrucks. Maybe that's high tech, maybe not. And I bet if I threw enough money to Eaton, they'd come up with a scaled version that was suitable to me. Want to invest? You'll get your full disclosure when you sign the check. He won't describe the cargo in more detail or the mountain? If I had, how would it help anyone identify the desired spring- storage mechanism? (and wants the location to remain a secret) Of course, because the commodity probably will remain slightly valuable forever. Eventually, maybe I'll stumble across a cost- effective transportation. If it was HIGHLY valuable, it would justify the costs of asking people who know what they're talking about. I think you are not well plugged into economic realities. Silver is more valuable than all but 3-4 other widely traded metals. yet there's not more than 2-3 places in the whole world where it's value- density is sufficient to justify the cost of digging it out of the ground FOR ITSELF. Silver is essentially a lucky byproduct, 99% of the time. Since the advent of Ebay, gigantic new trading markets have opened up for things that weren't previously worth the costs of trading. Why are you acting so shocked that I've stumbled across a similar paradigm? |

It also has to run on frictionless bearings and in a vacuum to actually
store the energy. that's apparently NOT a bridge too far: http://www.pcorp.com.au/index.php?op...FQkBYAod6U2mxA |

The thing I don't think I recall hearing is weight or volume per load.
Your viable options could change quite a bit with variations in those. Anyhow, since you had initially proposed a bicycle, I'd say you'd be hard-pressed to improve on the cost-efficiency of a moped. Taking the Eaton/Peterbilt approach, if you were able to drive your per-trip operational cost down to $.05 by virtue of, say, $100K in development costs, it would take a long time to amortize that start-up cost. Do you have a business plan so you know your break-even point? -- St. John, not ready to write a check just yet |

What are the economics of taking a blimp up and down a mountain? Now that I think of this, the question seems moot: if the economic good is at the top of a mountain, it should be easy to get it down: one only needs a method to control free-fall. If useable amounts of power can be harvested, that's a side benefit. There's no energy cost in lowering your commodity, the economics is in the start up and maintenance costs. |
