RainIons’ tailpipe & muffler prototype has never been closer.  Through the use of pyroelectric and/or piezoelectric material/materials, uniquely designed filters, and water vapor that is part of the internal combustion process, RainIons will create negative ions in a vehicle’s muffler/tailpipe.


The negative ions will eliminate vehicle emission pollution by (1) neutralizing positively charged pollutants, (2) making unstable pollutants even less stable (e.g., eventually causing decomposition); and/or (3) utilizing the electron affinity of certain molecules to absorb electrons.  

The uniquely designed filters and their specific placement will ensure that there is no engine back pressure concerns/issues and generate even more negative ions. 


Our partner, Bravo Team, is currently finishing computer simulations and the building of  the prototype to verify that technology will be a seamless addition to the transportation industry. We expect a successful prototype in mid to late Q1 2021.
