Amberg predicts that demand for underground

In her opinion, this business should become faster and more environmentally friendly.

At the same time, there is no shortage of work.

Recently, after 10 years of work, China completed the construction of a 20 km long railway tunnel in the Longmen Mountains.
In the UK, there is a railway project called HS2, which will connect London with cities and towns in the north of the country and will include over 100 km of tunnels along the proposed route.
Peter Westerbacka, who previously worked 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.
infrastructure will continue to grow—not least to protect against afghanistan number data 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 aren’t just for transportation. Troy Helming, founder and CEO of San Francisco-based startup EarthGrid, says power lines need to be laid underground. That’s what his company is aiming for. He notes that the vast majority of cables in the U.S. and Canada are above ground, making them vulnerable to hurricanes and storms, as well as the increasing frequency of wildfires.

“Our plan is to build a supergrid across North America,” he says, showing a map showing a grid plan stretching from the U.S. East Coast to the Pacific Ocean, with future wind farms in the west. The plan could help connect the U.S.’s fragmented power grid — and perhaps even eventually extend to Europe 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 is banking on plasma cutting technology, which heats the rock to about 6,000°C, shattering it to pieces. He predicts that the result will be tunneling through hard rock 100 times faster than with existing technology.
