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.

Harvard study finds human health risks from Canadian hydroelectric projects

Green Car Congress

In a new study, Harvard University researchers found more than 90% of potential new Canadian hydroelectric projects are likely to increase concentrations of the neurotoxin methylmercury (MeHg) in food webs near indigenous communities. The research is published in the ACS journal Environmental Science & Technology.

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. Rather, the panels reach far beyond Earth’s atmosphere to tap the distant cold of deep space. Sound crazy?
