NASA is Working on Electric Airplanes | Universe Today

One of the chief aims of space agencies and commercial aerospace these days is reducing the associated costs of space exploration. When it comes right down to it, it is still very expensive to send rockets into orbit, never mind sending them beyond Earth. But it’s not just the cost of sending payloads into space (and the pollution it causes) that concerns agencies like NASA.

There is also the cost (economic as well as environmental) associated with aviation. Jet fuel is not cheap either, and commercial air travel accounts for 4 to 9% of anthropogenic greenhouse gases (and is on the rise). For this reason, NASA has partnered with the commercial industry to develop electric aircraft, which they hope will provide a fuel- and- cost-efficient alternative to commercial jets by 2035.

Avis Testing A.I. Tech That Scans Your Rental Car for Damage | Digital Trends

Avis is working with Ravin, a startup that specializes in automated vehicle inspections for fleet operators and insurance companies. The system being tested uses CCTV cameras to take a 360-degree scan of cars as they enter and exit rental facilities. This allows Avis to take note of any issues before a car is rented out, so the customer doesn’t get charged for damage they didn’t cause.

Why Americans Don’t Buy Electric Cars (Hey, The Tesla Model 3 Isn’t That Popular) | Forbes

2020 is almost here but it’s still wall-to-wall gas cars. And it’s not just inertia. All those new cars are gas too.

My neighborhood in Los Angeles is a very rare exception with more than its fair share Model 3 owners as well as a small Chevy Volt and Bolt presence. But leave my neighborhood and travel to other locations around the U.S. and EVs pretty much vanish.

Yes, the Model 3 is a hit and has topped 500,000 cumulative registrations* but it’s not that popular. I mean it’s not the car that’s going to bring average car-buying Americans into the EV fold in large numbers. The price alone limits its appeal.

Why don’t we have electric aircraft? |Tech Xplore

Why do we have electric cars and trains, but few electric planes? The main reason is that it’s much simpler to radically modify a car or train, even if they look very similar to traditional fossil-fuel vehicles on the outside.

Land vehicles can easily cope with the extra mass from electricity storage or electrical propulsion systems, but aircraft are much more sensitive.

For instance, increasing the mass of a car by 35% leads to an increase in energy use of 13-20%. But for a plane, energy use is directly proportional to mass: increasing its mass by 35% means it needs 35% more energy (all other things being equal).

But that is only part of the story.

Aviation’s flight towards low emissions only fuels the crisis | Airline industry | The Guardian

At Cranfield University, the laboratory for much of British aviation research, the transport secretary, Grant Shapps, on Thursday urged the industry “to create an electric revolution in our skies”; for the climate and, incidentally, “to seize a share of a market that could be worth £4tn globally by 2050”.

Manufacturers are pursuing electric dreams: not just companies like Boeing and Airbus, but a host of tech firms, particularly for urban air mobility – aircraft that could be clean and silent enough to make shorter air hops possible without large airports.
