Researchers from MIT and Sun Catalytix develop an artificial leaf for solar water splitting to produce hydrogen and oxygen

Green Car Congress

Researchers led by MIT professor Daniel Nocera have produced an “artificial leaf”—a solar water-splitting cell producing hydrogen and oxygen that operates in near-neutral pH conditions, both with and without connecting wires. The cells were operated in a two-electrode cell configuration. (B) Reece et al. Click to enlarge.

New algorithm to allow Wi-Fi connected cars to share Internet connections

Green Car Congress

At the ACM SIGACT-SIGOPS Symposium on Principles of Distributed Computing this month in Portugal, researchers from MIT, Georgetown University and the National University of Singapore (NUS) will present a new algorithm that would allow Wi-Fi-connected cars to share their Internet connections. Unfortunately, what’s not cheap is communications.”
