Welcome to EM! Your handle makes me think you know of the famous Star Wars Del Sol that putters along around here in SoCal. It's not a good template for aero-mods (because it's designed for the vacuum of space,
).
For hydrogen stuff, you'll get a lot of skepticism on this forum. It's best to join a forum that is devoted to hydrogen like this one :
HHOINFO - The OPEN SOURCE Builders Network.
But for the majority of other mods, this is the place to be. I think the Del Sol is a great platform for MPG.
