It amazes me that a MacBook from 6 years ago still fetches up to and over $500 even though it's packed with outdated technology. A Windows-based laptop with the same hardware usually brings in about $50 or less. Go figure.
The second reason why the fan has to be made small still lies within the consumer trends and what they are looking for. The thinner the machine, the more popular it is likely to be. Take a look at the Mac Pro and you will see what I mean.
@Naperlou, when it comes to modern day laptops, one of the most important things that customers are looking for in terms of the specs is the amount of power consumed by the fan. Loosely speaking, the smaller the fan, the lesser the power consumed. The problem is usually how to make it use less power (i.e. make it small) and yet keep it effective and this is a true marvel of engineering at its best.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
