Adventure wears a lot of disguises. In garage laboratories, in pens behind their homes, in backyards, they’re out there enduring the smiles and shrugs of the non-adventurous.

Dear new explorers and experimenters,
You are WELCOME in the JLN Labs Group-List dedicated to the search of Free-Energy solutions and new generation of space-propulsion systems.
A Tesla adventure:
http://tech.groups.yahoo.com/group/usa-tesla/?yguid=320352404
For discussion of Nikola Tesla history, inventions, and coil design and construction techniques. The physics of Tesla’s varied patents, and ideas are especially welcome, even if they generate some heated discussions.
This list is for the dissemination and discussion of all things TESLA. Since Tesla was a man of wide and varied talents, other physical phenomena discussions are possible.

http://tech.groups.yahoo.com/group/Gravity-Antigravity/?yguid=320352404
This discussion group is devoted to the study of gravity and the physics of gravity and the interaction thereof. This forum is intended to allow all views and concepts to be entertained and evaluated by all, regardless of how traditional and fundamental or non-traditional and non-fundamental the ideas might be. Whenever possible, material submitted for discussion should include supporting data when available.
Or this:
In the Sandia mountains east of Albuquerque, New Mexico, there’s about an acre of house and museum built by a man with his own idea of adventure. It’s called Tinkertown. Above the entrance there’s a sign, “HERE’S WHAT I DID WHILE YOU WATCHED TELEVISION”.
He adventured through life creating thousands of Rube Goldberg mechanical animations just to see if he could do it.
If he couldn’t create that animation, or make a Cadillac with the outer-surface covered by pennies, he wasn’t half the man he thought he was.
And then, of course, there’s Ed Leedskalnin. http://coralcastle.com/ http://en.wikipedia.org/wiki/Coral_Castle
“We wonder what was the inspiration that could cause a man to spend 28 years to carve a Coral Castle from the ground up using nothing but home made tools. An homage to unrequited love? Perhaps to illustrate ancient sciences that defy gravity? Or maybe just sheer, raw human determination? The Coral Castle is an everlasting mystery to those who explore it.”
Or The Perfect Man Shrine, middle of desert nowhere, Columbus, New Mexico:
Human lives don’t last long. There are plenty of candidates who consider themselves wise and willing to tell us how we ought to spend ours.
But maybe when we close our eyes that last time we’d consider it well spent if we just did something, sometime while we were stumbling through it.
I’d bet not one of the people above ever voiced the lament, “I’m SO bored!”
