We give scientists and engineers great technical training, but we’re not as good at teaching ethical decision-making or building character. Take, for example, the environmental crisis that recently unfolded in Flint, Michigan — and the professionals there who did nothing to fix it. Siddhartha Roy helped prove that Flint’s water was contaminated, and he tells a story of science in service to the public good, calling on the next generation of scientists and engineers to dedicate their work to protecting people and the planet.
As the world’s climate patterns continue to shift unpredictably, places where drinking water was once abundant may soon find reservoirs dry and groundwater aquifers depleted. In this talk, civil and environmental engineer David Sedlak shares four practical solutions to the ongoing urban water crisis. His goal: to shift our water supply towards new, local sources of water and create a system that is capable of withstanding any of the challenges climate change may throw at us in the coming years.
A team has created a solar-powered device that can produce drinking water out of air — even in desert climates, according to the researchers from the Massachusetts Institute of Technology and the University of California, Berkeley.
