Jellyfish Undersea Roundabout

I don't really think the US would spend their entire 1.75tn budget on a tunnel

> The income from this new tunnel is expected to fund the next tunnel projects on the Faroe Islands.

Which seems like something of a rosy description. I tend to agree that this is going to require heavy subsidies. But back of the envelope:

- The "whole tunnel project", involving multiple tunnels, is estimated at 260m euros.

- One transit one way across the most expensive tunnel is estimated at 10 euros. The tunnels aren't very long, so taking a trip through one is not arduous.

- The project's costs of construction could be covered if every one of the ~50k residents crossed that tunnel 5,000 times. That's about 14 times a day over one year, or twice a day over 7 years. A 7-year payback time doesn't seem that bad.

- The problems in that estimate are:

-- Not everyone is going to use the big tunnel. Most of the population has no need to cross that route; they'll use cheaper tunnels or stay on their own island...

-- ...or they'll ride as a passenger in someone else's car. It's unrealistic to expect every resident, down to the babies, to pay for their own independent set of tunnel crossings.

-- The tunnels also need to cover the cost of their own maintenance. Maintenance on undersea projects gets tricky.
