Amberg, project manager for Amberg Engineering, the underground construction company founded by her grandfather. In her opinion, this business should become faster and more environmentally friendly. At the same time, there is no shortage of work. After years of work, China recently completed the construction of a km long railway tunnel in the Longmen Mountains. In Great Britain, there is the HS railway project, which will connect London with cities and towns in the north of the country and will include more than km of tunnels along the proposed route. Peter Vesterbacka, who used to work for Rovio, the developer of Angry Birds, has developed an ambitious plan to build an underwater tunnel between Finland and Estonia.
These are just a few examples. Amberg predicts that demand for underground infrastructure will increase in the future not least to protect against rising temperatures above ground due to climate change. "Maybe it's not so bad to have a place where we have a more consistent temperature," she says. Tunnels Switzerland WhatsApp Number List are needed not only for transportation. Troy Helming, founder and CEO of San Francisco startup EarthGrid, emphasizes that power lines must be laid underground. This is what his company strives for. He notes that the vast majority of cables in the US and Canada are above ground, making them vulnerable to hurricanes and storms, as well as increasingly frequent wildfires.
Our plan is to build a supergrid across North America," he says, showing a map with a plan of the grid stretching from the US East Coast to the Pacific Ocean, with future wind farms in the west. The plan could help connect the U.S.'s fragmented energy system and perhaps even extend to Europe at some point to tap into the vast potential of offshore wind there. "It's crazy and daring, and we know it," says Helming. One obstacle is extremely hard rocks, such as granite and quartzite, which can make traditional methods difficult or impossible. Helming relies on plasma cutting technology, which heats the rock to approximately , ° C, breaking it to pieces.
