Crazy Ideas Thread, Aug. 2015

polymathwannabe

This thread is intended to provide a space for 'crazy' ideas. Ideas that spontaneously come to mind (and feel great), ideas you long wanted to tell but never found the place and time for and also for ideas you think should be obvious and simple - but nobody ever mentions them.

This thread itself is such an idea. Or rather the tangent of such an idea which I post below as a seed for this thread.

Rules for this thread:

Each crazy idea goes into its own top level comment and may be commented there.
Voting should be based primarily on how original the idea is.
Meta discussion of the thread should go to the top level comment intended for that purpose.

If this should become a regular thread I suggest the following :

Use "Crazy Ideas Thread" in the title.
Copy the rules.
Add the tag "crazy_idea".
Create a top-level comment saying 'Discussion of this thread goes here; all other top-level comments should be ideas or similar'
Add a second top-level comment with an initial crazy idea to start participation.

You save energy not lifting a cargo ship 1600 meters, but you spend energy lifting the cargo itself. If there are rivers that can be turned into systems of locks it may be cheaper to let water flowing downhill do the lifting for you. Denver is an extreme example, perhaps.

According to Wikipedia:

Emma Maersk uses a Wärtsilä-Sulzer RTA96-C, which consumes 163 g/kW·h and 13,000 kg/h. If it carries 13,000 containers then 1 kg fuel transports one container for one hour over a distance of 45 km.

You already have to elevate each of those containers (with the train or truck from the coast). An electric elevator would be much more energy efficient than the current solutions are. A litter or so of diesel fuel of electricity per container. Less than 100 kilometers of shipping. Much less than 1000 kilometers of trucking.

If Denver ships out as much as it imports, weight-wise, pulleys could do much of the work of lifting. If there is a deficit in export weight, you could use the same water you were going to use as downhill flow to weigh down the counterweight.
