bobjengr, I didn't either. It's worth keeping in mind that this part of the recently renamed Airbus Group (formerly EADS), Airbus Group Innovations, is the former EADS Innovations, the same group that's been doing 3D printed metal parts for aerospace applications, which we've covered before, as well as lots of other cool R&D.
Thanks for your input as a pilot. The planned hybrid four-seater will extend range, although we don't know by how much.

ALL-ELECTRIC PLANE

Ann--excellent post.  I did NOT see this one coming and had no idea Airbus was working on an all-electric.  I wonder if flying this airplane would require a multi-engine certificate?  I have a single engine pilots' license but no multi.  I can tell you from my "student" days that going airborne for much longer than an hour was not advised so this plane just might be a great solution for touch and goes.  Cross-country would be out of the question and a "round-robin" would really be a stretch.  In the "dark ages", my instructor required a round-robin with three landings and one refueling.  My experience lasted about two hours with each leg being around 150 miles.  Not too sure this all-electric would fit the bill but it would be great for local work in the pattern.  Again--great post.  Very informative.

Pubudu, although this plane does not use solar energy, the 100% Solar Impulse plane flies whether it's cloudy or not, day and night because of its battery storage/recharge system. We wrote about it here

shehan, this plane does not use solar energy for propulsion. As the article states, it uses electric motors. The design of a solar-powered plane would be very different. The point of this plane isn't only to fly on all-electric power; it's to use cleaner, lighter technology in a craft designed to train pilots. As we saw with the 100% solar plane Solar Impulse 1 & 2, using all or mostly solar cells really changes aircraft design.

Solar is always a good alternative for charging batteries. It will never pay for itself, as the energy used in making the cells, building the charging system, etc. isn't such a hood deal, but that isn't the point. In an emergency or hard times or trying to look like you are doing something to "save" the environment, solar is nice. Maybe some day the costs will be low enough to actually be practical! But not today. Today politics make solar practical! I saw a Youtube video the other day about a simple Texas fellow's solar/wind setup. His was practical because it was to be used after the EMP we are being set up for. All of his silicon devices had been set up, tested, then taken down and stored in a Faraday cage. Yes, the cost would never be justified or practical, but his purpose redefined cost-effective. Oh great! Now I've opened another bucket of worms! I hope the fishing Is good today...

Not exactly. There are aviation precedents within the Airbus family, and what they've done with this is cobble together novelty by combining previous experience to come up with the design featured.

The twin ducted fan arrangement is a clever way of providing novice pilots with a One Engine Inoperative situation where the offset thrust line from the other causes the pilot to input corrective action fairly simulating what actually happens in multi engined aircraft.

So, there's a lot of innovation but also a lot of history making the design job easier.

I believe that the delay has occurred shehan, sola power is not providing the enough power for planes as a main power supply, and it will work better with a combination with other source such as fuel.

And also Shehan Sola panel will give constant power supply in day running but what happen in the night when flying.

@Ann – yes its nice to see a company initiating such piece of work than government forcing them to so.

@naperlou – Most countries are looking forward to use renewable energy sources, is France looking at doing the same?

Lots of people who write about robots say they give us jobs, instead of taking them away from humans. Based on the evidence in some recent studies, I'm not so sure.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
Purdue researchers have used a commercial sewing machine to quickly create stretchable electronics from conventional thin wire and a silicone elastomer used for making special-effect movie masks.
Researchers at MIT's d'Arbeloff Laboratory are developing shoulder- and hip-mounted robotic arms to help workers in aircraft manufacturing perform difficult or complex assembly tasks that would normally require two people.
