  Physics Tip


Viscosity
The property of a liquid that makes it resist flow or any change in the arrangement of its molecules. The higher the viscosity, the "thicker" a liquid seems.


 

  Physics Quote


It is impossible to trap modern physics into predicting anything with perfect determinism because it deals with probabilities from the outset.
    Sir Arthur Eddington (1882 - 1944)

Findings: Market Analysis

Analyses of current market conditions show that the demand for launches is currently driven by a small customer base. Launches of current science missions and communications satellites amount to no more than 20 launches per year.4 The analyses also show that this demand is inelastic with price.5 Projections show that once the price to space drops below $600/lb, new customers may then utilize the lower costs to begin future operations in space, increasing the demand for launches beyond the current levels. Figure 2 shows the projections, and is reproduced without exact data points.4

Figure 2: Market Elasticity

New commercial customers include pharmaceutical and microchip producers. Other ventures may include SDI or ‘Star Wars’ type programs, planetary asteroid defense, or manned Lunar or Mars missions.5

Possible to the "material that must bear it's own weight" problem. One, high-durability "balloons" attached at strategic points along the tether. Two, a series of perpetual floating platforms that can "hand-off" the item to be taken to space. Third, a combination of the two could be imagined as well.

I would love to read reports that discuss scientific thinking on these ideas.

Here's an artical about creating very long Nanotubes. Looks like just a matter of time before we get foot long tubes. With the right glues and faprication methodes these could be made into bundles of rope like meterial used for the space teather concept.
