Wow! That thing is huge. From the lack fire it looks like it's a peroxide mono-propellant rocket though.
It's also got a 9x cluster of engines just like the falcon 9. Looks like the got the shocks on the landing gear right too.
From the request for resume's of people experience in turbomachinery, it looks like he intends to develop a high-performance engine.

Taking a small snippet from that page:
Hydrogen peroxide, either in pure or diluted form, can pose several risks:
