Is there some way of making a compound with hydrogen and carbon, that would have high energy density, be safe to store and transport and economical? I know if sounds far fetched, but it might be worth considering.

When my great-grandkids ask me what we did for lighting before candles, I can say “electricity”.

I'll take "octane" for $2,000, Alex.
