I live in an area which supposedly has more than 300 inches of rain annually. Its raining much of the time and I think this water must have value somehow. Aside from being ice to eskimos. There are good quantities of old lava rock everywhere. The majority of which appear to be composed of silicon and aluminum. If I feel bored, I try to think of ways to monetize. To see what type of crazy ideas I might come up with. I think there are always opportunities lying in plain sight all around us. Its only a matter of becoming more skilled and patient in identifying and leveraging them.
