- The energy losses are proportional to the distance, says Richard Olsson, professor at KTH.

It puts such a spoke in the wheel to use electricity from African solparker in Sweden.

- The aim is to be able to maintain the same cost as cable production today.

It would not add more plastic, or use other specialized equipment, says Richard Olsson.

By increasing the voltage in the cables is expected to reduce energy losses by 60 percent.

Until further notice, the researchers are working to evaluate other types of nanoparticles, such as zinc oxide, to see if it is possible to find an even better plastic mixture.
