Intelligence and Happiness?

A while ago, the Inquisition pondered the nature of intelligence, and whether a certain outlook or attendant mental abilities are guides to or from happiness. This has been obliquely in the news of late…


Buried by the Sea

Human-powered Flight

The Gossamer Albatross might well be the coolest bicycle ever. Aside from having a name that could be confused with being an exclusive, designer condom, this bike was a plane. Pedalled by Bryan Allen in 1979, it flew 23 miles across the English Channel to Boulogne. Thirty years later, it is still an amazing feat.

It wasn’t the first human powered flight. That honour went to Gabriel Poulin, in 1921, when he won 10,000-franc Prix Peugeot, the first prize for human powered flight at Longchamps racecourse. Another notable mention here would be MIT’s Daedalus which came very close to flying from Crete to Santorini in 1988. Much like its Grecian namesake it met a watery demise.

The cold, hard facts: 34ft long and 16ft high, it had a wingspan of 98ft. The wing area was 488ft². Its empty weight was 70lbs, and its maximum measured speed was 18mph. But who cares? Its a flying bicycle.

The Albatross was created by Dr Paul MacCready, whose company, AeroVironment, is the market leader in researching clean energy solutions for sustainable flight and transportation. Mc Cready went on to produce a solar powered variant, the Penguin, which flew from Paris to the UK in 1981. These days MacCready may be best known for his unmanned solar aircraft produced for Nasa – the Pathfinder series. These have raised the possibility of infinite flight as their batteries can retain sufficient charge to fly through the night.

Variants 1: Human-powered Helicopters

These must be one of the singularly most unimpressive areas of human endeavour. The physics are just too unfeasible to make such flight worth it. As with all boffin-baited challenges, this does not stop people trying.

Although the Sikorsky Prize has not yet been awarded the California Polytechnic State University Da Vinci III, flew for 7.1 seconds and reached a height of 20 cm in 1989. The prize will be awarded to the first entry to reach an altitude of 3 meters (10 feet) during a flight lasting at least 60 seconds, while remaining in an area 10 meters square (36 feet square); so you can see it is completely pointless.
