Hi Dr. Christian.

What are the fuels that most of the world uses to launch rockets?

Do we have safer, more efficient alternatives or mixtures in the works or is that down to engine technology?

Also, what is your take on the green hydrogen economy?

Thanks. I've been following green hydrogen for a while now. I do a lot of research on public companies as I'm an investor, but also just fascinated with the technology. I worked in the oilfield on HWO units and we had to learn and work with all sorts of chemicals to stabilize different types of wells.
