THE GIST
Lightweight, compact devices could power medical devices.
Eat a Snickers bar to power up.

Tiny tanks of sugar and oxygen could power devices in space


These days, everybody’s looking for new sources of electricity. All our portable electronics -- iPods, cell phones, laptops -- they all need good batteries to keep playing or talking or calculating. The batteries we have really aren’t that good. They’re not much better than the voltaic pile battery Alessandro Volta invented more than 200 years ago.

Engineering researchers are looking into a new power source. They’re looking, well, into themselves.

It’s pretty simple – and complicated, all at the same time. Imagine a small chip – called a biofuel cell – that uses sugar and oxygen to generate electricity. Now, imagine that biofuel cell is implanted in your arm. The oxygen and sugar is in your blood. Can you see it now? Electricity. It’s always there and always being recharged. Runing low on power? Grab a Coke or a candy bar.

The engineers really aren’t interested in a new way for you to power your iPod. Not yet, anyway. They’re looking for lightweight, compact, dependable ways for astronauts to power things like medical sensors in space. Now, they’re getting ready to send one up in a satellite to see how well it does in orbit. No people. Just tiny tanks of sugar and oxygen. The people will come later, they hope.

Well, our iPod sounds like it’s going flat. Guess we need to grab a Snickers bar. See you next time.

Nature seems to be the favored source of inspiration for future renewable energy developments.

The newest technologies depend on either harnessing the natural forces of the elements, such as the kinetic motion of tides, or mimicking natural systems, such as the photosynthetic abilities of plants for better solar cells or more efficient biofuel or hydrogen production.

Now French scientists from the Joseph Fourier University in Grenoble have tapped another natural source for power – glucose found in living animals.

Glucose is a simple sugar used by cells as a source of energy. It is one of the main products of photosynthesis, and most forms of biofuel depend on accessing glucose from crops or biomass.

However, the French research team, led by biomedical engineer Philippe Cinquin, developed a biofuel cell that draws glucose from animal systems, and possibly soon, from humans.

The team successfully implemented the glucose biofuel cells in living rats, and found that the devices could produce up to 6.5 microwatts, with a maximum output of 24.4 microwatts per milliliter. The electrical output can remain stable at 2 microwatts for 11 days.

The scientists claimed that the biofuel cell could have significant applications in medicine. For example, the device can power a pacemaker as its output exceeds that of a pacemaker’s requirement of 10 microwatts.

This would allow the cell to last longer, and would also eliminate the need to surgically remove the device to be replaced as glucose could provide a potentially limitless source of energy.

The device uses enzymes to convert energy from glucose and oxygen found naturally in the body. Previous attempts of using such a device have failed because the enzymes required acidic conditions or were inhabited by charged particles in the fluid surrounding the cells.

The team was able to overcome these obstacles by confining selected enzymes inside graphite discs placed in dialysis bags. Glucose and oxygen flowed into the cell, but the enzymes remained in place and catalyzed the oxidation of glucose to generate electricity.

Mr. Cinquin is optimistic that the efficiency of the device could be improved and he sees no reason why the devices could not work in people.

He believes that the biofuel cell could be used in humans within five years to 10 years. Aside from pacemakers, the device could be applied in insulin pumps, artificial urinary sphincters, biosensors, bone growth simulators and drug delivery devices.

Hell no one is implanting nothing anywhere in my body,the only way that will be done is over my dead body heh,i wouldnt trust any form of implant no matter how good it sounds,i dont like the smell of it .:love:
