While you’re up, print me a solar cell

A 1% efficiency won't be a net-energy-gain for any sort of large-scale commercial production.

Three key questions:

1. What is the relative scarcity, if any, of the materials used to manufacture the "inks".

2. What is the durability/degradation under "field conditions" of the cell's active photovoltaic substrate?

3. Do the "inks" degrade in an environmentally friendly fashion?

It is this very ability of America to attract inventors (and other smart people) - from around the world, give them what they need and let them do what they love that makes me always bet for America and not against her.
