Meanwhile, jet contrails found to be a worse climate-change culprit than carbon

ELEKTRA ONE via PS-Aero

German company PC-Aero is trying to win NASA’s CAFE Green Flight Challenge, and Saturday they took a big step toward doing just that. The company’s Elektra One aircraft, designed by PC-Aero’s founder and president Calin Gologan, made its successful first flight. But this one-seater isn’t your average single-prop. Elektra One flies on electricity alone.

The Green Flight Challenge seeks a demo aircraft that can fly 200 miles in less than two hours on the energy equivalent of less than one gallon of fuel per person. Elektra One didn’t push the envelope that far just yet--the maiden flight hit a ceiling just above 1600 feet and lasted just 30 minutes, burning just half the 6 kWh stored up in its batteries. But the fact that the lightweight aircraft was able to comfortably circle the airfield for half an hour-- more or less silently, we might add--is nothing short of impressive.

And the timing for such a flight couldn’t be better. A study released Tuesday claims that airplane contrails--those long, white condensation trails jets leave in the sky--may warm the planet more on the average day than all of the carbon emissions spewed from airplanes in the history of modern aviation.

The carbon lingers longer of course--the contrails and any heat-trapping cirrus clouds they cause dissipate in hours or days, while the carbon remains for decades--but still, that’s a lot heat being trapped on any given day. Electric planes, as you may have surmised, wouldn’t contribute to warming on either front. See Elektra One take flight in the video below.

Felicitari domnule Gologan. Incet incet avansam catre avioane comerciale electrice. Sorry my romanian.

it's about time!

What rock do they live under?

Where do you think the electricity comes from to charge the dang blasted thing? Solar? Wind? Nuke? maybe.. but most likely Coal and Natural Gas.

Sick of these 'greenie weenies" claiming '0 Emissions" when, in fact, that claim can not be substantiated.

So they can make a plane fly on electricity alone but can't mass produce an electric car? WOW.

Also it's CHEMTRAILS that is contributing to the cooling. It's a governemnt program that's been going on since the 90's.

Normal contrails evaporate within a minute or two...these artificial chemtrails stay in the sky and actually expand into a misty haze.

I remember someone had tried to measure the effect of contrails on the surface temperature using the clear skies after 9/11 as a control.

actually, my "it's about time" was referring to the technological achievement, not so much the whole green thing.

The country of India is trying to develop AIR power automobiles. They store the energy power as compressed air in fiberglass tanks.
I wonder if somebody could create a recreational airplane \glider. You used you stored air to make the take off flight, use burst of compress air to maintain your flight and glide with strong air breezes as you can too. At the end, glide landing. Of course this is all my imagination....

@mwa3c - It depends on who you buy you power from. Look up Green Mountain Energy. You have to start someone, for renewable energy.

This is old news.Google SkySpark on Google video.I was struck by how much noise there is from what I assume is prop wash and wind over the canopy.I have read that electrically powered aircraft are very smooth,almost no vibration.

Contrails aren't caused by emissions, so an electric plane would make the same contrails

@mwa3c

When any one says zero emission when referencing an EV. Think about the context. Its in COMPARISON to a standard ICE VEHICLE .What it takes to make the energy and transport and store and run a vehicle and make a vehicle is the "net emmision" for the whole process/system.

That is an ICE carries onboard its fuel as do an EV. So in COMPARIOSN ..
ICE running vehicle(emmision) to EV running vehicle(zero emission)

However in in your own admission..you could techincally use solar/wind to charge it, build it and transport(that would be 0 net emission)

Side note: In the middle of ther desert i cant just expect to dig a hole and find gas..atleast with electric i can just plug in my portable solar charger!

WOW!! A plane inside which you couldn't fit a hamster AND which will cost in EXCESS of a million dollars U.S. How freaking brilliant!! But it's quiet, though. When are the wretched aviation engineers of this planet going to stand up JUST ONCE and persuade someone that some ideas aren't worth the blueprints they're scratched on? One final jab...an engine on a jet I was on just recently, caught fire and had to be shut down. Can we just focus on solving problems with our current equipment? Wouldn't THAT be nice?

@ Aldrons Last Hope, They mass produce electric cars all the time, The Nissan Leaf, The Mitsubishi IMev, anything from Tesla and many others.

@jsbrads contrails are produced from water vapour emitted by burning kerosene which is an organic molecule containing mostly carbon and hydrogen. When you burn a hydrocarbon the carbon combines with oxygen to give you CO2 and CO and the Hydrogen becomes H2O.

@mwa3c The prospect of a powered electric plane has potential when you consider that eventually and I dont mean in our lifetime. Those power sources you mentioned may actually be the only way to charge the batteries! Might as well start trying now as compared to later..Oh wait ... You would have thought that this would have been accomplished before now, hell we have have had electricity since the steam engine fist started charging batteries or powering simple lights..does make ya wonder.. I say its about time and nice to know its doable!

I have decided after reading your posts that you are a troll. I heard this same chemtrails statement made by an old boss of mine who was a scientologist and also added that it was the method the drug companies introduced diseases to further their profits! Not that his being a scientologist is wrong .. but even his other scientologist employees said he was crazy! So if you are a scientologist I am not in any way trying to start a fight, just quoting a truthful event and as I said the others of the same faith thought he was nuts..But he was still the boss so they did have to agree with him.
I no longer work for that company!

Just counter trolling:)

Thanks for reading

People who say "It's as easy as taking candy from a baby!" have never tried taking candy from a baby

Hmm nice try. Now we just have to wait for a small electric generator or more efficient fuel cell=) the energy density of batteries is lower than for current aircraft fuels. This is why we don't fly electric, it makes the aircraft too heavy, hence more expansive. Maybe the generator of Andrea Rossi could provide a solution, if its not a fraud.. guess we'll find that out at the end of the year =)
