Interesting to note, your first link says their quick charge time was "70% charge"... what happened to the other 30%? As to the other link... if they can get it to work, I'll be happy to be proven wrong (wonder how much a 120,000 watt re-charge will cost).

www.independent.co.uk/life-style/gadgets-and-tech/news/planes-go-hybridelectric-in-important-step-to-greener-flight-9943747.html
The first ever hybrid aircraft to be able to recharge its batteries took off yesterday — potentially signalling the beginning of a new form of low-carbon, green flight. Cambridge University researchers teamed up with Boeing to make the plane.
Hybrid engines — which are gaining popularity in cars — combine a battery and a petrol engine. Doing so uses 30 per cent less fuel than a plane with a petrol-only engine.
The petrol engine works with the battery-powered one at take-off and climb, when the plane needs extra power, but the electric motor can then switch into generator mode and recharges the batteries, or help the motor in minimising fuel consumption.
It's a physics thing- the next thing that is going to happen is hybrids are going to be the norm. Then slowly the gas motors are going to vanish. How to recharge a plane in flight? See Tesla (the man)
In other words, they haven't developed an electric engine that can power the take-off; the plane also needs the gasoline engine on constant standby. That's not sounding like "vanishing" anytime soon to me.

Not in planes- was just pointing out that the new norm is going to be hybrids. Maybe a couple decades- but not an if but a when.
Also it is possible electrics could take over the light duty market before hybrids get firmly established leaving them in the realm of other areas.

I think we're more likely to switch to water (hydrogen) by cracking the code on finding an efficient means of electrolysis (separating the hydrogen / oxygen molecules) preventing the need for widespread hydrogen distribution. We have existing water infrastructure. We could even use saltwater, or wastewater. That intrigues me far more than battery technology. Whatever replaces so-called 'fossil fuels' will have to be as, or more energy dense, and will have to provide the same or easier use. I agree with you- we will obsolete oil as a motor fuel at some point. That being said, the world runs on oil- we'll require oil for centuries to come. We also are not running out of oil, but we are running out of cheap oil. The benefit is that the rising price will spur the kinds of technology we're talking about.
