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. Excessive V in air and water has potential, but poorly documented, consequences for human health.

Generating Power on Earth From the Coldness of Deep Space

Cars That Think

But we have demonstrated that by directly using power generated by the cold universe, we can chill water to cool buildings by as much as 5 ºC during the day without electricity and light the night without wires or batteries. In the case of moving water, a turbine harvests the energy in the flow to generate hydroelectricity.
