Although it seems a joke, it is not. The New Scientist magazine has published in its Monday edition, this great invention. A robot that uses the sugar in the exoskeleton of the flies and allows (while flies from view) the robot does not need another power source.
If we read well the article we see that the thing is not as simple as it seems at first glance. Input power the robot obtained by breaking polysaccharide chains of the exoskeleton of the flies is very low and only allows the robot to move 2 centimeters every 12 minutes.
On the other hand, there is the problem of making the flies come ... but that have worked out well. The robot uses a flavor, synthesized from human feces, which attracts flies into a funnel that sucks up the digestive tract. Hahahaha ... you can not deny that is well thought out.
Robotic Anecdotes aside, the investigations that led to the invention of this robot open up endless possibilities:
- The energy of the polysaccharides can be used to supplement the solar energy to manufacture any kind of "thing" that needs to be energetically autonomous. (How about a robot that when not shine, eat potatoes, beets, ... or GM soy?).
- Production of electricity for households may attempt be made from the feces and organic waste, home users own: which would reduce the amount of waste that cities need to collect, process and eliminate. The most abundant polysaccharide in nature are starch and cellulose ... our wastes are filled with them. 50 gr. sugar can remain alight 40w bulb for 8 hours.
- The use of sugar batteries to replace batteries in mobile phones and other devices that need to be recharged by plugging into the mains.
- How about a water filter potabilice waste and generate electricity? Ideal for a spacecraft or orbital station. In general, ideal for any closed ecosystem.
