Because H2 gas is caustic, flammable, and explosive - and even below flash point, it is still reactive and going to cause chemical change, resulting in brain damage (the perforated 'spongebob' effect).

Not only does electricity cause strokes, it also causes alzheimers/dementia, leukemia, epilepsy, and abnormal brain growths.

If grouped together, electricity is the leading cause of death. We need solar panels that make themselves (a 3D printer that prints more 3D printers, solar panels, and little 'roomba' robots with big wheels on the sides that strip mine resources for it). This process could double up on itself and in hardly any time at all our whole population could have free safe solar panels to replace our corroding, leaking electrical grid.
