This seems like a rather counterintuitive statement from a self-professed inventor.

After all, billions upon billions of people have roamed the earth since the creation of humanity. By your logic, they should have already solved every crisis and invented every device. There should be nothing left to create.

Given that this isn't true, we gain nothing by dismissing innovations as snake oil solely on the basis that the "professionals" have already thought of everything. I'm not defending this device, but I'd be a fool not to evaluate it on merit, rather than my own preconceptions of what is and isn't possible.
