Car Powered Using Compressed Air
Jules Verne predicted cars would run on air. The Air Car (link broken, so it was removed) is making that a reality. The car is powered by compressed air which certainly seems like an interesting idea. Air car ready for production (link broken, so it was removed, sigh, when will site stop failing the web so badly?):
Refueling is simple and will only take a few minutes. That is, if you live nearby a gas station with custom air compressor units. The cost of a fill up is approximately $2.00. If a driver doesn’t have access to a compressor station, they will be able to plug into the electrical grid and use the car’s built-in compressor to refill the tank in about 4 hours.
The car is said to have a driving range of 125 miles so by my calculation it would cost about 1.6 cents per mile. A car that gets 31 mpg would use 4 gallons to go 124 miles. At $3 a gallon for gas, the cost is $12 for fuel or about 9.7 cents per mile. I didn’t notice anything about maintenance costs. I don’t see any reason why the Air Car would cost more to maintain than a normal car.
The air car was named one of Time magazine’s best inventions of the 2007.
Five-seat concept car runs on air
An engineer has promised that within a year he will start selling a car that runs on compressed air, producing no emissions at all in town. The OneCAT will be a five-seater with a fibre-glass body, weighing just 350kg and could cost just over £2,500.
Tata is the only big firm he’ll license to sell the car – and they are limited to India. For the rest of the world he hopes to persuade hundreds of investors to set up their own factories, making the car from 80% locally-sourced materials.
“Imagine we will be able to save all those components traveling the world and all those transporters.” He wants each local factory to sell its own cars to cut out the middle man and he aims for 1% of global sales – about 680,000 per year. Terry Spall from the Institution of Mechanical Engineers says: “I really hope he succeeds. It is a really brave experiment in producing a sustainable car.”

The World’s Best Research Universities
Shanghai’s Jiao Tong University produces a ranking of the top universities annually (since 2003). The methodology used focuses on research (publications) and faculty quality (Fields and Nobel awards and citations). While this seems a very simplistic ranking it still provides some interesting data: highlights from the 2006 rankings of Top 500 Universities worldwide include:
Country representation in the top schools:
||% of World
|% of World GDP
||% of top 500
|The rest of Europe
Update: see our post on 2007 best research universities results
Top 10 schools:
- Harvard University
- Cambridge University
- Stanford University
- University of California at Berkeley
- Massachusetts Institute of Technology(MIT)
- California Institute of Technology
- Columbia University
- Princeton University
- University Chicago
- Oxford University
