Nanoflowcell is a string of companies, registered in Liechtenstein, Switzerland and most recently in the United Kingdom, presenting cars that are claimed to be using flow cell batteries to power cars. These flow cell batteries are supposed to be fueled by salt water of two types, "organic" and "non-organic" salt.
The person claiming to have invented this fuel cell, Nunzio La Vecchia, is a song writer making elevator music. He also claims to be a musician, although music videos with him performing don't show his hands and his face at the same time except for extremely simple motions.
The cars presented by Nanoflowcell have been designed by Koenigsegg, and are branded as "QUANT E".
There is a lack of scientific understanding or patents describing how salt water can be used to produce electric energy with the efficiency and energy density that the company claims, and no independent third party measurements confirming the claims are available. The claimed performance contradicts research that has been done on flow batteries. It has been said that "there is no solid proof just yet that the QUANT E actually works and performs as advertised".
Nanocells Chairman, Jens-Peter Ellermann, has the title 'Professor' in many interviews, yet no university seems to employ him. He does offer violin courses and promotes himself as a "Star-Professor" on his website 
Nunzio La Vecchia has been accused of fraud in connection with a revolutionary photovoltaic cell that was supposed to have an extremely much higher efficiency that competing cells. In a court case he explained that the prototypes had been destroyed for security reasons in 1999 or 2000.
As of 2015, no competitor comes close to the claimed efficiency. Similar accusations were made in connection with a car that was supposed to run on photovoltaic cells with an efficiency that could not be explained by science. The car was never sold to customers.
