Oh and BTW, if my math is correct, that $2,000 for the Platinum, works out to about $50.50 of the Anaorak..if it works out after all. Almost 2 grand off the sticker price right there.
It just struck me, that if they vcan develop a system to use sunlight to split water into hydrogen and oxygen, anf if theyt have indeed found a significant amount of water on Mars, this would be able to support a Mars base with not only water, but air, and power, without having to transport it from Earth. Heck, the soil might even be used in a greenhouse to grow food.
I think your math is off.. considerably. A kilo is roughly 1000 lbs, that's 16,000 ounces for $2000. Compared to $2000. per once of platinum. That's .125 cents for an ounce of this gortex material.
How much of a savings that would be depends on how much platinum is used in a car sized fuel cell's electrodes. The savings would be pretty much the total cost of the platinum minus the few cents worth of gortex material.
The problem I suspect they would have using this material is heat would destroy it in a actual fuel cell.
Far as I know, carbon nano tube "cloth" shows a more realistic promise in the world of fuel cell development.
