Magic Motorways

Futurama city for the motor age

In the “Highways and Horizons” pavilion at the 1939-40 World’s Fair in New York, General Motors presented Americans with “Futurama”, a vision of the city of 1960. Norman Bel Geddes designed an enormous scale model, showing a utopian city rebuilt for the motor age, completely separating cars and pedestrians. Five million people came to see the exhibit, waiting more than an hour for their turn to get a sixteen-minute glimpse at the motorways of the world of tomorrow. There
is a technicolor movie of the show online, as well as the accompanying book that Geddes wrote to explain his (and the motor industry’s) ideas (or propaganda): “Magic Motorways“.

Update: another movie here (via). Related: London traffic improvements (the Bressey Report, 1938).

How to Depave the Planet

The crack garden. “A crack team of guerrilla gardeners will undertake tactical missions to etch similar tectonic fissures in the parking lots of failed suburban malls and abandoned inner neighborhoods of post-industrial cities. With pneumatic drills or with pick axes and some elbow grease, they’ll wound the earth’s (un)natural asphalt skin, so that forgotten ecologies may return and hopefully fester”. Via Pruned.

A Perpetuum Mobile Railroad

Perpetuum mobile railroad

The March 1925 issue of Science and Invention featured this Aerial Railroad. By a combination of inclined ramps and overhead suspension from cleverly curved tracks the “trolley car” passenger vehicle could go forever without power. It falls while suspended in the air from the downward inclined track, swinging forward as it does. When it contacts the lower tracks its momentum carries it up the inclined track until the whole process repeats. Source.

This unconventional sailing boat, named the SailRocket, reached a record speed of 47.35 knots (87.6 km/h or 54.43 mph), on average over a distance of 500 meters. During another run, the boat reached a speed of 52 knots before lifting off
for a spectacular in-the-air wipeout (also caught on video). More below.

Miracle biofuels

“If you grow jatropha in marginal conditions, you can expect marginal yields” & “The best outcome might be to slow down the jatropha steamroller and let science sort out whether it can be grown on a mass scale in ways that
make it preferable to food-based biofuels”. Read. Related: Leave the algae alone.
