Study finds heavy-petroleum fuels raising vanadium emissions; human emissions outpacing natural sources by factor of 1.7

Green Car Congress

Breathing vanadium-rich aerosols has unknown but potentially adverse health impacts, according to the researchers, who note that the human impacts on the global vanadium cycle parallel impacts on the global cycles for lead and mercury.

Generating Power on Earth From the Coldness of Deep Space

Cars That Think

But about a decade ago, our research group at Stanford designed a material that’s remarkably efficient at sending heat out to that reservoir of cold while preventing heating from both the sun and the environment. With the ambient environment as a hot reservoir, we can use the coldness from deep space to create the cold reservoir.
