Agree with you there Marek
A better idea would be to invest in a fleet of buses (vintage perhaps) that can run circuits to the Castle, town, Heights, Docks, De Bradlei, Crabble, Painted House etc.
EH don't need the cable car to attract visitors as the benefit will be negligible. Getting some decent exhibitions, displays, interpretation, open up the Cold War level of tunnels, will get people there.
Making it into a site that needs 2 days to do properly will get people to stay in the town and see the other attractions.
Sort the transport issues by using old military parking area at Connaught to connect to the Castle and made the site itself car free.
Lay grass on the rough carpark behind the Officers' Mess and use that for events like jousting.
Use the Officers' Mess itself as a great hospitality site and also have a major archaeological display.
I'm sure that all of this can be done with the millions that it will take for the Cable Car
