Patents will be filed at the appropriate time.
Patents are the right to sue.
Without ample cash flow, a patent cannot be defended. Once Solar Motor Works has the required cash flow, Patents will be considered and not before.
Most patents can be circumvented.
China and many nations do not honor patents. Why bother when they can just reverse engineer, copy and produce with slave labor.
They have the backing of international bankers and care less about some American company with a patent.
There is a way to protect the intellectual property rights of Solar Motor Works engine technology. This is a long discussion reserved for backers only.
Either way, without cash flow, any attempt to protect rights is a waste of time. It is by design...
The primary reason to secure rights, as opposed to "giving it all away" for the benefit of all, is a basic economic reality. Unless an investor can have return of capital and a return on capital, they will not invest. Without investment in production lines, the cost of the engine will be very high and nobody will benefit. The utopian notion of helping the poor will never come to being.
If you want "free energy" all you need is this technology at a low cost. If you get 1000 mpg on Natural gas, you are 1:200 the current fuel costs, or basically "free energy." We don't need "cold fusion" or some magical new source of energy.
We need this engine technology...
