An interesting concept on prototyping stages that is shure to revolutionize drilling operations as we know them today:
When it comes to drilling, we pretty much still do it like the old ways: A physical diamond (or some very hard material) head that gets in contact with the rock to be drilled and there you go.
This of course implies in several limitations, as well as having to replace that expensive drill head every now and then.
This flame drill however, will change lots of things. It can go deeper, it’s 10x faster, won’t need the replacement of that drill head… very promising.
