Titanium sheets and additional aluminum deflect or block road debris, better protecting the lithium ion battery in the Model S.
When it comes to cities, being big and rich is better for the planet than being big and poor, according to a new study of carbon dioxide emissions from cities around the world. But is this correct?
Engineers have built a powerful microscopic engine that relies on the combustion of hydrogen and oxygen. One problem: nobody knows how it works.
A factory that takes in raw materials and produces finished battery packs could lower costs for the most expensive part of an EV.
If electric cars become popular quickly, the demand for charging them is likely to exceed supply. Now mathematicians have worked out how electricity companies can distribute their power fairly to car owners. But the price--accurate information about driving habits--may be too much to ask.
A new study says methane leaks make natural gas trucks worse than diesel powered ones.
Electrodialysis has the potential to desalinate seawater quickly and cheaply but does not remove other contaminants such as dirt and bacteria. Now chemical engineers have worked out how to do that too.
Large cities are more productive than small ones so it shouldn't come as a surprise that they produce more CO2 as well, say physicists.
Electric vehicles can be so quiet that they pose a new risk on the road. But what kind of artificial sound should be added?
A proposed pipeline from Canada won't increase greenhouse gas emssions.
