Rolls-Royce is working on a zero-emissions plane with a target speed of 300+ miles per hour.

Rolls-Royce and Airbus hope the hybrid plane, known as E-Fan, will be ready for maiden test flights by 2021, Newby said. The program is expected to serve regional airline flights, rather than long-haul jumbo planes, according to the partner companies. And it's not likely to be ready for commercial flights for years, allowing for engineering and testing before full deployment.
Fully-electrified planes at passenger scale are far away, and so far are being designed in the expectation of serving shorter-term flights with fewer passengers. Eviation's plane is designed to seat nine. Rolls' has a partnership with the Norwegian airline Wideroe to electrify its fleet of regional airplanes by 2030. Norway has a goal of carbon-free domestic air transport by 2030.
At Pratt & Whitney, the bigger short-term push is to build the market for the geared turbofan engine, which went on sale commercially in 2016. A more fuel-efficient conventional engine, it has enabled a 16% reduction in fuel consumption in Airbus A320s, the company said. The engine had a number of quality problems early on, which a company spokesman said Pratt & Whitney has resolved.

Just Give Us the Greta Thunberg Documentary AlreadyGreta Thunberg, the 16-year-old Swedish activist whose sick burns might actually cause Donald Trump to rupture an artery, has captured the world’s hearts and minds as the determined face of a generation trying desperately to get adults to acknowledge and take action against the realities of climate change. Now, she’s finally getting the documentary treatment in a forthcoming film from Hulu that will trace her activism from the school strike in which she asked “If you don’t care about my future on earth, why should I care about my future in school?” to her recent appointment as Time’s Person of the Year. Sure, yes, give us her timeline, but also give Greta plenty of time to make fun of world leaders. [Deadline]
