How does it work?
According to Daniel Styger from GWWK you can imagine a filled bath tub. Opening the drain automatically leads to a swirl in the water while draining off. This phenomenon caused by the gravitation is the basis of this patented technology.

One more fact is remarkable about the plant in Schöftland (Switzerland): it’s a collaborative project financed by 100 private sponsors.

I largely share this view – except the iPod. To my mind this device is just a consitent enhancement of Sony’s good old cassette-based Walkman based on today’s technology – although I have to admit that the Apple’s success is impressive. I would trade the iPod in for a technology from the energy sector like the battery or solar cells or perhaps already photovoltaics.

The German Research Center for Artificial Intelligence is working on devices and systems to recognize the reading flow of your eyes and respond to it. With “Text 2.0” pictures related to the text you are reading at this moment can be displayed and further explanations or translations of certain words can be shown just in time. A really fascinating prospect of future reading experiences.

Imagine you want to tour the 10 biggest cities in the UK – one route might start in London (number 1) and finish in Bristol (number 10), for example. The solution to the Hamiltonian Path Problem would be the route that takes in each city just once.
This simple problem is surprisingly difficult to solve. There are over 3.5 million possible routes to choose from, and a regular computer must try them out one at a time to find the one that visits each city only once. Alternatively, a computer made from millions of bacteria can look at every route simultaneously. The biological world also has other advantages. As time goes by, a bacterial computer will actually increase in power as the bacteria reproduce.
