Receiving power from where? 40MW is the capacity of a medium sized wind farm.
The larger tunnel configuration uses 1.38GW. That’s more than most large scale coal or nuclear plants.
Even if they could obtain the supply from a plant operator the cabling to get to the site of the tunnel cost a fortune
- sparker72678 4y agoIf you had pure copper conductors could you even get enough into a 1 meter space to conduct that much power? If we're going to need high temperature superconductors and fusion power, this isn't the first thing I'd use it for. (I can't deny the fun factor of this, though.)
- Schroedingersat 4y agoAn 1cm-ish thick copper cable can handle about a kiloAmp without melting. At 10kV you'd need 12 of them, so call it a 5cm thick bundle with some kind of cooling for the 1m tunnel that needs 120MW.
