My favourite feature in The Economist is its 'Technology Quarterly' that shows up 4 times a year. The latest one came in the previous week's issue, featuring another series of interesting technologies. I was particularly intrigued by the article on 3D printers titled 'A factory on your desk'. I've never heard of this technology of additive manufacturing that produces things in the same way the inkjet printer produce print-outs. The machine basically applies thin layers of materials successively to build up an entire product. More importantly, the article suggests that printers for individual use might be emerging as companies such as Z Corporation. These machines are mainly used for rapid prototyping but nowadays companies are trying to use them for direct manufacturing.

'Only humans allowed' discusses the developments in CAPTCHAs technology - the weird stuff that Google makes you read and type in a form box when they think you're a bot trying to use its server to execute a query.

The typical feature of Tech Quarterly is articles on energy and for this issue, The Economist went on with updating readers on Wind turbine technology. Finally, those interested in life sciences might like to note that biology seem to have taken a turn towards methods of 'engineering'.
