We aren’t running out of water, but dealing with trucking water to a fracking well is expensive.. massive amounts of water are needed to perform the procedure and you have to treat the water after you are done because it is full off all sort of nasty stuff you don’t want seeping into the water table. A mobile device that can cut down on the volume of water needed and to help clean up the waste water generated is a major win.
Now, for the bonus round.. who invented the fracking procedure to begin with?
Stanolind Oil and Gas Company (> Pan American Petroleum Corp > Amoco > BP) developed the process then called Hydrafrac. In 1949 this process was then used commercially by the Halliburton Oil Well Cementing Company “Howco” under an exclusive license until made available to others in 1953.
I knew a college professor that held pneumatic fracturing patents for remediation.
