Greetings friend @madridbg
Every day, something ends up surprising us, I confess that I had not heard information about internal combustion engine, which will use ceramic membranes, whose effect does not generate any emission of pollutant gases into the environment, without doubt, a breakthrough in this of designing more environmentally friendly technologies. Great publication, best regards.
Greetings @lupafilotaxia, every day there are more advances in environmental care, however, we have not yet evolved 100% on this issue. Thanks for your comment.
