ARPA-E awarding $60M to 23 projects; dry cooling and fusion power

Green Car Congress

The Energy Department’s Advanced Research Projects Agency-Energy (ARPA-E) will award $60 million in funding to 23 new projects aimed at creating highly efficient and scalable dry-cooling technologies for thermoelectric power plants and developing prototype technologies to explore new pathways for fusion power.

The challenge—in which 3,800 teams from 100 countries participated—was to “design and build a safe, quiet, ultra-compact, near-VTOL personal flying device capable of flying 20 miles [32 kilometers] while carrying a single person.” And physics says that you need more power per unit weight to lift an aircraft like that.”

The technology behind Ford’s Lightweight Concept Vehicle; prospects for Mach-II with 50% mass reduction difficult

Green Car Congress

The Ford Lightweight Concept reduces the weight of a 2013 Fusion to that of a Ford Fiesta, resulting in a nearly 25% weight reduction. Matt Zaluzec, Ford technical leader, Global Materials and Manufacturing Research, was the use of technologies that are targeting the use of mixed materials and that are available today.

Since Power = Current x Voltage you can put the same amount of power through a conductor at a lower current with a higher voltage. This is important since the power dissipated by a wire is Current^2 x Resistance a lower current means less power lost on the lines and more efficiency for a high power load such as a car.
