Iranian Scientist Finds New Way to Generate Power

Tehran, Iran | Posted on February 12th, 2012

Iranian Associate Professor Kourosh Kalantarzadeh discovered a new power source.

The breakthrough was made jointly with other researchers at the Massachusetts Institute of Technology (MIT) and RMIT University in energy storage and power generation.

The power generated relative to the energy source size is three to four times greater than what is currently possible with the best lithium-ion batteries.

The team was working on measuring the acceleration of a chemical reaction along a nanotube when they discovered that the reaction generated power.

Now the two researchers are using their combined expertise in chemistry and nanomaterials to explore this phenomenon.

Their work titled Nanodynamite: Fuel-coated nanotubes could provide bursts of power to the smallest systems is in the December IEEE Spectrum Magazine, the publication of the IEEE.

Associate Professor Kalantarzadeh said that his experimental system, based on one of the materials that have come from nanotechnology - carbon nanotubes - generates power, something researchers had not seen before.

"By coating a nanotube in nitrocellulose fuel and igniting one end, we set off a combustion wave along it and learned that a nanotube is an excellent conductor of heat from burning fuel. Even better, the combustion wave creates a strong electric current," he said.

"Our discovery that a thermopower wave works best across these tubes because of their dual conductivity turns conventional thermoelectricity on its head.

"It's the first viable nanoscale approach to power generation that exploits the thermoelectric effect by overcoming the feasibility issues associated with minimizing dimensions.

"But there are multiple angles to explore when it comes to taming these exotic waves and, ultimately, finding out if they're the wave of the future."
