Researchers have created a generator of electricity from live shellfish

In the coming era of cyber science revival of animals, as researchers have long been producing electricity using the power of the living creatures that can make the function, for example, the size of the tiny spy device or radio-sensitive sensors. A research team from Clarkson University in Potsdam, has made a new step towards tomorrow, learning to extract energy from conventional clam. The resulting energy is sufficient to ensure the work of a small motor.

The same research group had previously shown as snails could survive the introduction of biofuels are completely inorganic elements. This time, the American and Israeli researchers have their inventions on three live shellfish and mollusks then joined together as a pack to create enough electricity to run the electric motor - a step to the theory, as shown in the movie "The Matrix" in 1999, in which Morpheus compares a person with battery Duracell.

"The problem with clams was in the assembly of individual cells into a kind of battery," said Eugene Katz, a professor of chemistry at Clarkson University in Potsdam, New York.

Katz and his colleagues introduced biofuel elements securing special electrodes within the cavity of the main shellfish filled with blood, so that blood sugar, a source of energy to the elements of biofuels. Researchers accurately allocate time "work" clams that they rest between periods of collecting energy to shellfish could restore the level of sugar in the blood.

Researchers have tried various ways of combining the three clams in one group, which would be used as a collective living battery. Serial connection scheme increases the battery voltage (electric potential), while a parallel circuit amperage increased - but the total amount of electricity available, often varies depending upon the health of each clam.

Various power fluctuation "is trivial for ’normal’ galvanic cells, but not easily tolerated by living cells of the body, because we all molluscs have different electrical properties, depending on the physiological conditions of their existence," Katz said in an interview with InnovationNewsDaily.

Battery with three clams, charges the capacitor of about 29 millijoules little more than one hour - a sufficient amount of energy to, ultimately, the electric motor shaft to turn a quarter of a full turn. In comparison, a 75 watt lamp uses 75 joules (75 000 mJ) per second.

Such indicators - are still far from U.S. forces or government agencies that use the creatures as tiny spies capable of incorporating nutrition and their own technological devices. But this is the result of just one of many similar experiments aimed at trying to extract energy from living organisms. Katz and his colleagues found only three reports from other laboratories on the elements of bio-fuels that are embedded in the rabbit, rat and conventional laboratory cockroaches.

"We have the right to distribute some of the technical problems - most electronic devices requires much more energy than we can give of our biofuel batteries" says Katz. His work has been published in the edition of the journal Energy & Environmental Science on Wednesday, April 12.

Researchers have already begun work on new experiments that will test how well the battery will be able to biofuel to power a variety of microelectronic devices. Next on their list: lobster.
