It would be great use of my money, were I a billionaire, to build a vacuum-insulated sodaduct & cervisiaduct as a ring going around Europe perhaps with a monorail on the bottom (for convenient repairs) & photovoltaic cells on top to power it the monotail. Technically you can have two monorails for one track, one above and one below, so the upper monorail could be used for something else as well. The ice & carbon dioxide would be delivered separately to keep the the drinks fresh, and there would be few be a different pipe for drinks from different German & French & Spanish districts inside the cervisiaduct.
