Free-Source Space Vehicle Design

By far the coolest thing about the Internet is its ability to allow quick exchange of knowledge across vast distances. The ability to transfer this information would be pointless without someone at one end with something worth spreading the word about.
Linux is a prime example. It does a great job and is a way of "sticking it to the Man" simultaneously.
But take a look at what these guys have posted. http://spacetethers.com/
They've designed what they consider an excellent way of getting into Low Earth Orbit and beyond. In fact, they claim they can get something to LEO for roughly $6 a pound. Compared to what it costs today (around $1,000 per pound) that's quite a promise.
Now, there's no guarantee their plan will work. They may not make a single dollar; may never get a single foot off the ground, but no matter. They are trying to make a go of something with little more than a dream and an Internet presence. Not the best foundation, granted.
But just think about the possibilities. Think about what might come of their plan: A daily delivery service to friends and families colonizing the Moon, or living in orbit on a private station.
Even if all they ever do is tout their wares in the ether of the 'Net, it's still something we should all get excited about.
A dream is fantastic. A dream shared among the population of a planet, is something altogether more fantastic.
