No wonder here on my part. Hydrogen is a poor fuel choice for any application other than space craft. A hydrogen economy is a false economy

*sigh* more vaporware.

I doubt airbus could even afford to build a plane that looked like that, let alone one that was powered on hydrogen. Concept vehicles - does anyone still take them seriously? Are investors really that easily taken?

Maybe someday they'll invent "metallic hydrogen" (what science fiction book was that from?). Superconducting at room temperature, 50 times more dense than liquid hydrogen.

Oh, and it only takes a black hole to make it.
