Ummm.. Started out in Victoria BC Canada, then sta
Sub-topic of ES thread "Aerodynamics":
http://endless-sphere.com/forums/viewtopic.php?f=3&t=52981

(In which some landlubbers express "concerns" re higher speeds and rough pavements. OTOH, on the water, my daughters when young used to enjoy jumping off waves at 2-3 times local harbour speed limits with their Dad/Skipper basically sailing "single-handed" (and local police acknowledged they weren't quite sure how to catch us/"pull us over"/wattEVer, our boat being a "high speed (at that time an Olympic-class) "Tornado" class/design of light-weight "catamaran" made of... watt some sailors referred to as "Frozen Snot" plastic foam sandwich construction w/alum mast and "boom" w/"blocks and tackle" (ropes plus "pulleys") to adjust sail in/out "on the fly". Basically, if ya hit ANYTHING boat will "self-destruct" so police weren't TOO worried.

So topic of this thread relates to using the "free energy" of the wind as a "power-assist" (under the right conditions) to extend range of available battery capacity, etc. A "stern" (back end) sail, sorta rectangular or triangular shape tall but "skinny"-ish. Think "wind surfer" on shore.

Let the "concerns" begin (re vehicles -boats - I have used for decades, including once on an empty paved parking lot).

Yes?

(PS. ON the surfaces of the water? Sometimes VERY "rough pavements".)
 
This exists already, long before ebikes ever hit the masses.

"google > nonsensical post"???

So, my post "nonsense"? Or yours? Or some other post here? (Current laptop isn't working 100% for me yet.)
 
could not resist to "Re-cycle" some funny ideas I cam along in the aerodynamic topic

if you are after a Wind powered bike - i am afraid only few would be candidates unless they are living in windy area, maybe it would look like :

rather than this

or this

on the other hand, I was not aware of little Wind mill able to charge some electric devices :

above all, most of the topic is oriented how to reduce aerodynamic drag, which makes sens, somehow
 
All those contraptions look like they are very efficient at making you stand out in a crowd.
Just the thing LockH needs while looking cool at the local cafe with his Current laptop working on his next thread which no one gets.
 
OMG I just about choked to death on my coffee from that, ROFL

I know Murvagh well; it's about twenty miles away. In, fact my brother might possibly be in there somewhere as he hires Blokarts (the mini landyachts). You can see why no one runs them on the road. They need far too much room!

Hehe... Hi JennyB. Thought is to fly a not-too-tall spanker sail off "aft" (rear/back) to have adjustable by... "pilot"/rider/driver for when wind direction and speed is right. An "assist" to the ebike battery-electric "assist". (Plus sail mid-panel has clear plastic slots to insert contact info (web site). Web page has info re rentals:

And PEP offers an upgrade to convert to legal "power-assisted bicycle" as seen on ES:

Could work, does work - where conditions allow. Cyclists have been using skate sails for over a century, probably. Round here there's too many hills and hedges, and that's the way I like it! :D
 
Currently rewatching movie "The Hunt for Red October" (turned up on website You-something. Hehe). And was struck by the HYDROdynamics of submarines. So had to look up the fastest swimming fish:
http://www.top10stop.com/world/fastest-fish-in-oceans-and-seas-top-10-fastest-swimmers

Millions of years of "Product Development"/evolution to swim (fast) through a really thick atmosphere. The human animal, on the other hand, at any sort of speed through the air? Think proverbial "broad side of a barn door". We've at least already progressed (a tiny % of us) to the recumbent trike "Velomobile". Like this:

Look sorta "fishy"? Hehe... Anyway, was just reminded of this thread (rather than that "other" thread re "aerodynamics", where it seems the object is to avoid the possibilities of "wind assist")

Now back to your original ES programming.
