America’s innovative company EarthGrid has invented a device that can drill tunnels without touching the rock due to extremely high temperatures.
The EarthGrid company, which has said that it can drill a distance of one kilometer per day, also said that it costs only 300 US dollars to dig a one meter tunnel.
It is said to be 100 times more powerful than current drilling machines and 98 percent less expensive.
Due to this, even projects that were abandoned due to high cost of materials are now possible.
