Short line so that the tow assist person has the slope to help.

That looks like something that might have been found painted on the wall of some prehistoric cave. :)

Man has dreamed of flight for a long time. We're lucky to live in a time when it's more than just a dream. :thumbup:

How close to launch is the bike path?
Are electric wheel chairs allowed on the bike path?
How about a pulley tow launch with a wheel chair with a barter for free lessons for a paraplegic.
TV coverage.
Even though one can't walk doesn't mean one can't fly and roll off and in on big wheels.

An "Air Wall for a soaring back drop. Not as grandiose as the video link but on a diminutive but adequate scale.
Good for ocean beach areas.

Make a shallow beach soar-able with adequate height inflatables.

1. The bike path on the north half of the launches is immediately close to the launch level; then the level to slope edge averages on the north launches about two HGs worth; that is, let wing spans parallel bike path and slope top edge, then things are very crowded.

2. Bill, I am not sure I understand about the wheelchair. I here will take a try on a couple of scenarios:
A. Electric wheel chairs are allowed on the bike path. Have a group of electric wheelchairs pull a tow line through a far-field pulley to launch a HG; then give lessons to each wheelchaired person?
B. Use far-field pulley and drive tow line via persons-pulling to tow up a wheelchaired person? Do this free. There are beach balloon big wheel wheelchairs at some beaches.

Bill offered attention on artificial walls:

Nice find, Bill !
There been several points in the hang gliding literature about artificial walls, slopes, and curtains. Indeed there can be some experiments at Dockweiler. Keeping costs down and safety up will be part of the picture.

There is a family of methods that aim to use the wind to help form walls/slope/ ...
1. Well anchor with soft sandbag anchors a billowing line of sails.
2. Cable between posts edging the bike way and then set sails to form a fence that causes the wind to rise up over the sail fence.
3. Friends could be fence posts holding a fencing sail taut between the two friends (or more than two). This could be temporary just for one flight at a time; then the sail comes down. The bottom of the sail could be sand anchored.

Use ambient wind to fly a line of playsails.

Excellent point! Use gravity for the tugs!

Mod: Y line arrangement with two friends tugging; they will stay out of the flight path of the HG. Short lines as you suggest. Tug; let go; drag line on sand.

================================================================

Another tug driver: The return of water after ocean wave: capture the returning water with a water chute (that may be depowered and reset by opening line and having an apex pull ready also arranged; spill all water and bring water chute back for another go).

Hey Joe,

2. Bill, I am not sure I understand about the wheelchair. I here will take a try on a couple of scenarios:

Yes. This way, (2. A). Keep the tow wheelchair on the path for near field pulley to launch. Tow distance length, only of about 12 to 15 feet for launching only. (ATC height restrictions.)
This would require releasing at the pilot. So not as risk retentive as man towing a short tow line to be dropped and drug on the sand.
