When I was a kid I had this incredibly cool idea to connect the major cities of the world by underground monorails. They would be in vacuum so they would have no friction.
…rummages through old files…
WOO HOO! I can’t believe I found it. OK, here it is:
Line 1: Winnipeg (2), Denver (5), Phoenix, Mexico City (2,3), Tegucigalpa (Honduras) (8), Lima (7), Santiago.
Line 2: Mexico City (1,3), Los Angeles, San Francisco (5), Seattle, Vancouver, Edmonton, Winnipeg (1), Toronto (5), Montreal (6), New York (3), Paris (10), London (9).
Line 3: La Paz (Mexico), Mexico City (1), Houston (4), Atlanta (6), Washington, New York (2), Boston, Halifax.
Line 4: Chicago (5), Houston (3), Havana, Port of Spain (Trinidad) (6), Georgetown (Guyana) (8), Brasilia (7), Rio de Janeiro.
Line 5: San Francisco (2), Denver (1), Chicago (4), Detroit, Toronto (2).
Line 6: Montreal (2), Philadelphia, Atlanta (3), Miami, Port of Spain (4), Caracas (8), Asuncion (Paraguay) (7), Buenos Aires.
Line 7: Lima (1), Asuncion (6), Brasilia (5), PPR (see below), Algiers (12), Cairo, Jerusalem (13), Baghdad (14), Tehran, Bombay, Calcutta (8).
Line 8: Colombo, Calcutta (7), Rangoon (14), Taipei (15), Manila (9), Honolulu, Tethys (see below), Tegucigalpa (1), Caracas (6), Georgetown (4).
Line 9: Reykjavik, London (2), Brussels, Berlin (11), Vienna (13), Kiev (10), Islamabad (14), Novosibirsk (14), Ulan Bator (Mongolia), Seoul (15), Tokyo, Osaka, Manila (8), Yaren (see below).
Line 10: Dublin, Paris (10), Monaco (11), Rome, Sarajevo (13), Kiev (9).
Line 11: Lisbon, Madrid (12), Monaco (10), Bern, Berlin (9), Copenhagen, Stockholm, Oslo.
Line 12: Madrid (11), Seville, Algiers (7), Abidjan (Cote d’Ivoire), Accra (Ghana), Lagos (Nigeria), Yaounde (Cameroon) (14), Johannesburg (13), Antananarivo (Madagascar).
Line 13: Cape Town, Johannesburg (12), Gaborone (Botswana), Nairobi (14), Khartoum, Jerusalem (7), Istanbul, Athens, Sarajevo (10), Vienna (9), Prague, Moscow, St. Petersburg.
Line 14: Yaounde (12), Nairobi (13), Riyadh, Baghdad (7), Islamabad (9), Novosibirsk (9), Lhasa (Tibet), Rangoon (8), Phnom Penh (Cambodia) (15).
Line 15: Seoul (9), Shanghai, Beijing, Macao, Hong Kong, Taipei (8), Ho Chi Minh City, Phnom Penh (14), Bangkok, Singapore, Djakarta, Perth (Australia), Sydney, Wellington.
Notice the complete ignorance of geopolitical realities, relative population and economic importance, fiscal and environmental impact, and plate tectonics displayed. This was probably the coolest featherbrained scheme I cooked up as a kid, along with the maglev mass transit system for Winnipeg.
It was coupled with another scheme: to create four laser-powered jet takeoff spaceports on the equator, at St. Peter and Paul Rocks in the Atlantic, Colombo, Yaren (Nauru) in the Pacific, and Tethys, an artificial floating city a few thousand miles off the coast of Ecuador. The idea would be to beam unfiltered solar power collected by satellites by laser (which explains their being in the middle of the ocean) to power jet-powered spacecraft, which would then take off due eastward to take advantage of the impulsion of the earth’s rotation. And where would they fly? To the international, rotating, ecological space habitat, of course!
