The gas canister alone would cost a grand for one time use. You couldn't use a normal compressor because it would be too slow. Imagine the pressure nessesary to lift 600 Lbs of cement and cement sets in less then 40 minutes. How would you effectively hydrate the cement inside a sealed bag before it sets? The air tight inner membrane might cost a thousand dollars. The undisclosed impregnated fiber is not going to be cheap. The cement has to remain wet while it cures. how is that managed? The desert is too cold at night and too hot during the day. Where do you find the perfect conditions for setting one of these up? Plus three of them would flatten a normal pickup. Theres a reason these guys don`t even have a prototype. The concept is unworkable.
