How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

The climate crisis is also having a severe effect on the planet, which is being battered by pollution, deforestation, and soil degradation. Ninety-nine percent of the global population breathes in air that exceeds WHO-guideline limits on pollutants, with low- and middle-income countries suffering from the highest exposures.

The New Supersonic Boom

Cars That Think

The main obstacles will be regulatory and, especially, environmental: Supersonic airliners could be hugely more polluting than their subsonic counterparts. The best-funded of this group is Denver-based Boom Technology (which also goes by the trade name Boom Supersonic). Will people soon be jetting across the Pacific in three hours?
