DaveS,

" Rigid wings are far more expensive in kPower and Fort's comparisons". Yes, but not per pound.

PierreB

Excellent. Nuts as rigid wings, and something like Cotton_candy as soft wings being less expensive by area but more expensive by unity of weight.

Rigid glider http://www.kollmanwings.com/Prices.html : about 120$lb

Paraglider http://shop.flybubble.co.uk/advance-iota : about 320$lb

Some correction,

Rigid glider http://www.kollmanwings.com/Prices.html : about 120$lb

Paraglider http://shop.flybubble.co.uk/advance-iota : about 320£lb (about 470$lb)

DaveS,

Lets agree facts against your "Rigid wings are more expensive by the pound" (Rigid glider http://www.kollmanwings.com/Prices.html : about 130$lb, and paraglider http://shop.flybubble.co.uk/advance-iota : about 470$lb) instead of wrongly arguing. Good ideas _ like scalability of soft wings _ do not win by false statements.

PierreB

DaveS,

"Another factor Pierre seems to ignore is that large rigid wings...".  Pathetic! So a time again:

DaveS,

So a new time again:

No DaveS,

My price-comparing are between soft and rigid gliders both on the same basis, so both on the market , showing your "Rigid wings are more expensive by the pound" is wrong.

Your price-comparing between tarps wings and rigid wings (for AWE like Makani or Ampyx? Or marketed for flight?) has a sense for equivalent things. Where is your tarp-AWE? Data of electricity production? I advice you to put it on Instructables to finish your tarp-AWE and propose it for public. After some beginning of comparison will be possible.

DaveS,

Your wrote:"The prices for tarps and cheap kites being used in AWE R&D have been shared, and are just as public as the selected prices you chose to reason from. Your data seems like price-comparing an expensive bicycle to a cheap car, to misleadingly conclude that bikes are more expensive."

I underline false logic or false statements then comment.

1. "The prices for tarps and cheap kites being used in AWE R&D have been shared, and are just as public as the selected prices you chose to reason from".   So you can compare tarps against fabrics.
   
2. "Your data seems like price-comparing an expensive bicycle to a cheap car"  : the question is about your "Rigid wings are more expensive by the pound"  ,my examples proving the contrary by a factor of 2 to 5. Note replace "seems" by "facts".
   
3. "Your data seems like price-comparing an expensive bicycle to a cheap car"  : please again NO "seems", but FACTS. Precise again expensive in whole or by pound?
   
4. "to misleadingly conclude that bikes are more expensive": false statement, conclusions are for price per pound, by your  "Rigid wings are more expensive by the pound" .
   

    

    

I understand Doug wanting correct your posts and asserting "all he tells is wrong" and agree, although sometimes you produce a good idea, as a settled watch gives the correct hour once every 24 hours.

DaveS,

How are you informed of what you write?

My comment is (if there is a part of true within your post) Makani could be seen as the leader of open AWE by collaboration with TuDelft (and also indirectly by Instructables). So congratulations to Makani.

So Rod as promoter in open source AWE holds the good hand in Instructables, widening the circle of open AWE becoming Makani-TuDelft-Kpower. The Great AWE Debate is forming!

No, the rig I suggested would only lift the gantry automatically.
Prusik knots are clumsy enough, they slip occasionally too. Especially over tight line.
This is not somewhere to compromise on safety.
