I don't know why it's never been done before. Will probably turn you into a human combustion chamber afterward though.
Or an actual combustion chamber, depending on how hardcore you are.
I think chamber is the wrong word. Chamber hold things in. I think the word "caldera," may be a more appropriate. I don't think there will be much holding that in the "chamber" once consumed in mass quantities.
perhaps the word rocket would be more accurate? Provided the walls dont decide to rupture.
As if a pizza taco could rupture a robot....
It's our primary fuel! We're only tricking you weak humans into thinking it's stupid solar energy.
"Why stupid?" You may ask. Because you can't throw a 5lb "solar" taco at an unsuspecting moron.
