I wonder if the boring company has any plans to create tunnels that could be used for gravity energy storage.
After all, if they have the tech to continuously bore long tunnels, boring straight down becomes a much easier task as you don't need as much anchorage to provide forward pressure.
You can essentially use the front plate of a TBM, and have it "fall" into the ground with a large weight behind it.
- marshmallow_12 6y agoBetter idea (maybe): store even more gravitational energy by sending heavy weights into orbit. Just use booster rockets to make it fall through the atmosphere, regenerating vast amounts of energy in the process.
- detritus 6y agoThe problem then being: how do you remove the mass you're extracting? Existing horizontal TBM systems make this much easier.
- lambda_obrien 6y agoDon't, just price it into the project and leave it down there.
- detritus 6y agoI meant the dirt, not the TBM itself.
- lambda_obrien 6y agoHmm yes, quite. Never thought about that haha.
- skybrian 6y agoGeothermal looks promising, using the technology for drilling wells.
