Kateeva says its new manufacturing equipment can produce affordable displays based on organic light-emitting diodes.
A more efficient engine and composite wings that fold up will reduce fuel consumption on Boeing's 777x.
Polymer glue helps fracture-prone high-capacity batteries last through more charges.
EPA says it wants to lower the amount of ethanol oil companies are required to blend with their fuel.
Toyota says it has reduced the cost of fuel cells significantly enough to sell hydrogen cars for under $100,000.
Stanford researchers say new materials could help lower the cost of producing fuel with solar energy.
Conventional batteries take so long to charge that they cannot efficiently store braking energy. Graphene supercapacitors store almost as much but charge in just 16 seconds.
A material described in Nature could help lead the way to high-efficiency, inexpensive solar cells.
As the solar industry matures, it better start worrying about dust, as SunPower is with its solar panel washer acquisition.
In a smart city, every electric vehicle must have access to a charging station within its driving range. So how should these stations be located? The good news: computer scientists have solved the general version of this problem. The bad news: it's NP-hard.
