$74.99 seems like a good price. However, this is at a time when the need for tungsten is down due to the evolution of the light bulb to LEDs. The question is how much tungsten is required for a solar panel? How much tungsten will be needed for, let’s say, a 30 acre solar cell farm? What will that cost? If I were a lawmaker giving out research grants, I would make sure all of the math was done to know the costs for the final product. I am sure the run-of-the-mill lawmaker is only thinking about how to line their pockets and not the practical matters of costs. They would sell their mothers down the river if it lined their pockets.
