Something for you to work on next John !

This video shows the components better

Believe me, if I could make a practical electric helicopter I would do so in a heart beat. Everything about electric drive is better except one. If batteries could hold even 1/4 the amount of power that gasoline can we would never have seen a gas powered car or a gas powered much of anything. But since batteries still have a ways to go to compete with the energy density of gasoline we are still stuck with gas power. I've already dabbled in electric power and have motors in house ready to go if we ever get batteries that can give more that 15 minutes of flight. But until then an electric powered helicopter won't be much more than a novelty like this one. But its coming, I read about battery advances almost every day on the tech sites I follow. Lithium air and Lithium sulfur are getting closer to reality all the time.

Here is another story about an R44 helicopter that was converted to electric power.

This is a link to the video of it's test flight..

Here is more info about it..

I know you had mentioned having motors available, but I think this one might be very promising.

I think the motor may fit in the desired performance range but I likewise have yet to find batteries that might work.

Hi John,

I am very interested (as you...) by having my mosquito powered with electric motor in the future... As you follow the evolution of the battery market, do you found anything new about it ?

What do you think of that ?

Thank's

I read about new battery innovations nearly every week on green car congress, autoblog green and new atlas but rarely actually see a new battery come to market. I haven't seen this one yet though. They say 1.5 x current density on their website and 2x in the booth but no mention of what the density actually is! If they have 400 wh/kg that would be certainly be a game changer so long as it costs less and is safe. I guess we'll see how they do. Thousands of people working on new battery chemistries since whoever comes up with it will be a billionaire.

Thank's for your reply John. Let's hope there will be something really interesting within the next 3 years...

And what to think of this... ? Not new and the inventor get apparently killed... an electro-magnetic engine with no need for battery... better to not even think about inventing that otherwise you get killed... if true, what a world...

Remember Steorn and the Orbo? They even put an ad about their free energy source in the Economist to try to get followers. There has never been any device that defies the law of conservation of energy and never will be. We don't really need it anyway since we have tons of energy available, we just need to be able to store it more efficiently.
