thanks for the repys,

So far I think it's a good idea to use the trains we already have to
transport the passengers.

I was thinking to make sails the same width and half the height of the
train.

Put them in sets of 4 on their own set of wheels.

Then attach a row of such carts to the front and rear end of the train.

The amount of carts you take with you depends on how brutal the wind is
that day.

If there is non you bring non. :-)

I have no idea how often it would be useful.

But now that I've imaginated a size with the sail of the imaginary
apparatus maybe you could tell me how much carts we need to create an
interesting "wingspan" for our earth rotating windmill of sailnovation.

never

hello scotty,

with "never", do you mean each individual sail is to small to pull the
cart

or would it require to much carts to be useful?

''never'' was in response to the usefulness of it.

With "IT" what do you mean specifically? And how did you come to this
conclusion?

Are you referring to public transport? :-)

The carts don't have to be heavy if they can be clamped onto the rails.

I imagine 60 mini sails could pull a reasonable size train or at least
help pull it.

do you have any clue as to how much a train weighs? how
much HP is needed to move one?

But of course I do,

The idea is to use conventional trains and use the sails to assist.

Electric trains can generate about 30% of the energy used to accelerate
while breaking.

If (on average) we could shave of (only) an extra 10% the sail would
already be interesting.

For now I think solid sails are the best solution, I've updated the
page a bit.

hello Scotty,

With "never" do you mean each individual sail is much to small

or would the row of carts get to big.
