Although the new ceramic motors will have to be disposed of, they are smaller than batteries and, because they last longer, there will be fewer to dispose of. They could, therefore, help reduce the problem of waste disposal pollution.
Of the new motors, however, it must also be said that they run on fossil fuel, which scarcely helps with regard to pollution and global warming.
Also, the existing battery industry is well-established and the new technology has to be introduced and accepted worldwide.
In addition, could there be a safety factor involved with the indoor use of the new motors?
