Brian J. Jankura was wrong (``Hydrogen may not be the answer,'' Voice of the People, Nov. 28) that we can't use our Ovonic triple-junction photovoltaics to break up water through electrolysis. We can, and we do.

He was right, though, that ``manufacturing'' the fuel requires electricity. That electricity comes from the sun's light (photons) interacting with our thin-film lightweight solar cells to produce electricity.

Of course we love electric cars, but hybrids will have to do at the moment.

Jankura was wrong again on his two other points. Hydrogen is a fuel. When one mines coal, one is doing that to get the small amount of hydrogen. The carbon in coal is only the carrier of hydrogen, which is what gives the energy.

When one drills oil and then processes it, it has only a bit higher hydrogen content than coal; the ultimate fuel is hydrogen, which is not difficult to produce and, in containers of our Ovonic solid hydrogen hydrides, is transportable by ordinary means such as trucks, trains and barges.

Unlike gaseous hydrogen, which Jankura thinks we are using, the Ovonic solid-hydrogen hydride canisters we plan on making in Akron are safe. The U.S. Department of Transportation permits us to transport them anywhere.

Our Ovonic nickel metal hydride batteries, which store hydrogen in the same manner, have been extensively tested to the extreme for many years by the world auto industry. These hydride batteries have enabled the present rapidly growing hybrid auto industry, which is producing higher-value jobs that feed back on education.

One need not imagine what happens in an accident. Jankura's fears only apply to high-pressure gaseous hydrogen or liquid hydrogen, which are both very unsafe. What is unsafe for the world is having pollution, climate change and wars over oil caused by relying on fossil fuels for our energy.

Lastly, I receive no benefit but joy in being able to provide this basic new industry to Akron, my hometown.
