need spring-energy-storage mechanism
i think i need a spring energy-storage mechanism. Maybe a very large
wind-up clock motor? the scenario is: a slightly-valuable commodity originates at the top of a mountain. More or less a bushel at a time. there is an existing paved road. the commodity fetches a price, but not enough to pay for very much transport. the concept is to use a cargo bicycle, maybe with trailer, to carry the items down to the bottom of the mountain, "winding up the clock" on the spring-storage. at the bottom, the load is transferred to buyers. the now very-much- lighter bicycle is to be driven UP the mountain, using the stored energy. Any cat which will catch the mice is fine with me. I'm just thinking that anything involving electricity, hydraulic fluids, etc, will be too involved, and losses throguh two conversions. Capacitor storage might be feasible, if there's high quality ones being sold. The charge doesn't need to held for long amounts of time. Down the hill, then back up. Ideally, this will be a ready-to-go or mostly ready-to-go commercial item. I am rather mechanically/electrically handy. But this is business, not pleasure. Time spent should be cost-effective. |

Ideally, this will be a ready-to-go or mostly ready-to-go commercial item. I am rather mechanically/electrically handy. But this is business, not pleasure. Time spent should be cost-effective. I have been thinking along the same lines. Compressed air or chemical batteries appear to be real loosers due to the heat loss. Mechanical springs or flywheels would seem to offer a lot more efficiency. Flywheels have to be heavy or fast. Neither characteristic is very attractive for a vehicle. 1) How hot does the spring get when it is cycled? 2) How many times can the spring be cycled 'till fatigue diminishes its capacity? With that information, it should be easy to compare the energy density with other mechanisms. A few haphazard google searches hasn't offered up the answers to those questions in the manner to which I become accustomed so I may have to dust off some old texts like "How to do research" or "Real work as a moral virtue" :-) Sue... |

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. |

Used in Italy to get supplies to and from mountain tops. Two cables, one pulley, two carriers and a long bit of rope. Fantastic! Throw a few clothes-pins in the package and it is also a clothes dryer for sweaty cycle shorts. Sue... |
