Why?  Don't we have enough roads?  Apart from the structures (which I imagine can be made out of ever lighter materials) which components are going to necessitate all this heaviness?  Even the heavist components could be transported to within a km or so of site via light-rail (? etc.)  Lightweight clip-together rail systems could be used to transport large items from railtrack to site...etc...labour intensive (good!), out in the open (good!), new materials lightening the load (good!)...

How much rail do you need to get within 1km of "the site" if all the turbines are 2km apart from each other? You need 2Km of road/track per turbine!

Okay, a simple calculation:

How much infastructure do you currently need to supply/build/etc. the oil/gas/coal system?  Let's say you need that much plus some more to implement a distributed wind-turbine structure.  But you don't need the heaviness (or the width?) and you are talking about dropping (or dragging, or pulling etc.) a descrete number of mechanical parts plus cables to a specific number of locations once-in-X-years.  Let's say X=25.  For the other 24 years and 300 or so days...peace and quiet...the lanes can grow over, vegetable can be planted...the lack of ongoing intensive polluting activity...  For a given area there could be one factory (very small scale) near a train track and connected via communications media to other centres...best practice passed along...ever better and lighter machines helping humans to build an ever better and lighter system...

Sommat like that?

And why not start by placing wind turbines every 2.5 km along existing roads and rail lines?  How much power would that generate?

We talked about this. The point is that going from building along existing transportation infrastructure does not translate into building on a sparse 2D grid.

By we talked about this, do you mean that past discussion on wind power along railways? If yes, you haven't made that point explicitely, and I understood what you were on about only now.

Good point, but re rg, the idea of resurrecting field railways, e.g. temporary tracks, is attractive to me...

Yes, field railways to get to a windfarm site is a great idea.

Small tracks which could be built up to a range of, say, 10 km, then connected up to the nearest wind turbine(s) for power--the ones along the roads if we're thinking of how to get out beyond the current road/rail infastructure.  Then you use the new wind turbine(s) to step out another 10 km in every direction?

How about field maglev tracks?

I'd call it completely unrealistic :-) Field railways were rarely electrified (their whole purpose is to be simple and easily re-layable), and if a field railway is to carry wind turbine parts itself, overhead wire would be in the way of the large pieces. If we want to go non-fossil here, I suggest battery locomotives.

Great photo!

It looks very long, what is it, 60m?  I can imagine that a track can be made in 60m-straight sections.  Is it very heavy?  Too heavy for a light-rail solution?
