What mean the expression "business casual"?

(Question submitted by Kri)

In some urban settlements and connected (bars, clubs, restaurants) is to avoid giving the impression that the site can be visited by countrymen. Something that is very easily understood elsewhere (a farmer, it kills atmosphere).

Thus, in these places, people must wear clothing associated with occupations or areas exclusive to large cities, hence the term "business casual".

example, are considered "business casual" clothes cardiac surgeon, the uniforms of professional baseball players or even the rags of beggars.

Conversely, it can occur in an establishment requiring "casual" dressed in a plaid shirt and a chain saw or even wearing a yellow raincoat and a halibut.

How does the compressed air engine?

(Question submitted by i.trevidic)

is too much, but then there, too simple.

An internal combustion engine drives a belt which in turn drives a turbine. The turbine compresses a gaseous mix (composed, among others, 78% of nitrogen dioxide and 20% oxygen) in a steel tank. This compressed air can then be released on demand via a valve (no less) in a drive wheel, thereby propelling the motor vehicle equipped with the famous compressed air.

Note that currently, engineers (no less) work on a second version of the compressed air engine. We try to make this simpler mechanism by subtracting the portion "compressed air". The idea is to increase the energy produced by the combustion engine directly to the wheels of the vehicle.
