Read the book "Outliers". There isn't anything to discover, this is just a cash grab for dumb people.

I see, too bad I didn't think of it. Anyone who thinks that they can find the answer to this question only in the genes of their offspring, and are willing to pay for it, are obviously too stupid to raise a child well enough so that it may attend college, so basically whoever does this test should get a "no" immediately.

But a lot of current renewable energy sources lack any meaningful way to store the produced energy. Why not use the excess electricity wind and solar can create, which can not be stored, to produce hydrogen instead?

It is probably way easier to do, and doesn't need as much rare earths as giant lithium batteries would need. Also, hydrogen can be used for many things, including just electricity production if need be.
