Tiny flakes of plastic, generated by the wear and tear of normal driving, eventually accumulate in the soil, in rivers and lakes, and even in our food.
I wish it was pure iron dust wearing off that steel, but no. The flying drone idea seems good, but for harvesting?
Exhaust gas is poison.
The relatively high amount of metal contents emitted from diesel engines strongly suggests that the measurement on the control of metal contents in diesel fuel should be taken in the future.
As, Hg and Se exhaust emissions were dominated by fuel combustion while Cd, Cr, Cu, Ni, Pb, and Zn exhaust emissions were dominated by lubricant oil combustion.
Where have all the steel wheels gone?
They went around smaller steel wheels:
