Boring Company Speeds Up Tunneling. Vegas Loop Tunnels Could Finish in 2025

The Boring Company is deploying the PruFrock 3 tunneling machine at Tesla Gigatexas. The PruFrock 3 machine will be able to dig continuously. It will only need to stop to change out teeth and other parts as they wear out. The Boring Revolution youtube has analyzed the actual tunneling rates on actual real world projects …

Zuckerberg is Making a Bunker But Bomb Resistant UHPC Buildings Could Become Common

Ultra-high performance concrete (UHPC) is an enhanced fibrous and cementitious concrete with high compressive strength (120–250 MPa) particle packing density (0.825–0.855, tensile strength (15–20 MPa) and extraordinary durability. UHPC has 300 times the ductility and energy absorption of high performance concrete (HPC) and three to sixteen times the compressive strength of regular concrete. A $100+ …

Rotating Detonating Engines Can Enable Practical Hypersonic Planes

The main problem holding back reusable hypersonic planes is that traditional ramjet engines become very inefficient over mach 2 while hypersonic engines do not work well below mach 4. There is the need to solve the hypersonic speed gap between mach 2 and mach 4. Rotating Detonating Engines can be more efficient up to mach …
