The Great Electric Air Race Has Begun
The title of this post is the first sentence of this article in The Independent, which is entitled Electric Planes: Could You Be Flying On A Battery-Powered Aircraft By 2027?.
This is the full first paragraph in an article by respected travel writer; Simon Calder.
The great electric air race has begun. Three European industry heavyweights have teamed up against a US startup and Britain’s biggest budget airline to develop the first commercial electric aircraft.
So is such an aircraft feasible?
When you consider that the three European heavyweights are Airbus, Rolls-Royce and Siemens, I suspect that the proposed project is serious.
It should also be said that the companies are not aiming for an all-electric aircraft, but a hybrid plane with a very efficient on-board generator and a two-tonne battery.
The key to success will probably include.
- Batteries with a very high energy density.
- A highly-efficient and quiet gas turbine, that generates a lot of energy.
- Radical air-frame design to take advantage of the technology.
In my view, the batteries will be the key, but making more efficient batteries with high charge densities will also do the following.
- Improve the range and performance of battery and hybrid road vehicles like buses, cars and trucks.
- Improve the range and performance of trains and trams.
- Transform energy storage, so wind and solar power can be stored and used in times of high demand.
- Allow every house, apartment or office to have its own affordable energy storage.
In all of these applications, the weight of the battery will be less of a problem.
This leads me to the conclusion, that we may see smaller electric plasnes in a few years, but the technology that will make it possible, may well improve other modes of transport so much, that electric planes are never an economic proposition.
It’ll be interesting to see what happens!
I think most travellers and members of the oublic will benefit in some ways.
If Microsoft Built Cars…
There are loads of jokes that start like this and you can find pages on the Internet like this.
But what if Microsoft built planes?
This article on the BBC shows the result.
The plan is to use the Stratolaunch plsne to launch satellites. More is here on Wikipedia.
The idea is not new, The North American X-15 of the 1950s, was a space plane that was launched from under the wing of a B-52 Stratofortress.
Wikipedia says this about the flights of the X-15
During the X-15 program, 13 flights by eight pilots met the Air Force spaceflight criterion by exceeding the altitude of 50 miles (80 km), thus qualifying these pilots as being astronauts.
Not bad for an conventional rocket-powered aeroplane built over half a century ago!
My New All-Purpose Shopping Bag
I bought this stringbag for £2.95 and when I go out, it fits neatly in my shoulder bag or pocket.
My New All-Purpose Shopping Bag
Isn’t a stringbag the most useful of bags? After all it did lend its name to that most mighty of the Royal Navy’s attack aircraft; the Fairey Swordfish, which was called the stringbag on account of its ability to carry virtually anything to its target. Wikipedia has a full explanation.
The Swordfish is almost unique amongst military aircraft for two reasons.
Several aircraft types were built to replace it in service and it out-served them all.
In some attacks, it pressed the attack home successfully, because it flew slower than the low limit of the gun-aiming computer of the ship being attacked. The Germans hadn’t believed that an attacking aircraft would be as slow as a Swordfish.
But this unusual biplane did carry out one of the most unlikely battle successes of the Royal Navy, by attacking the Italian fleet at anchor in the Battle of Taranto. The lesson was not lost on the Japanese, who inspected the port after the attack. But the Americans, who must have known what happened at Taranto, did nothing to change their thinking.
Vapour Trails Over Hackney
I took this picture this morning.

They’re not normally this clear, but the sky was very blue at the time.
A Clip of Video from the RAF
The RAF has just released this video taken from the Lancaster during the flypast to mark the Diamond Jubilee.
Note that the pilot and passengers in the Lancaster, are wearing very 1940s bone-domes. It would also appear, that there are quite a few free-loaders going along for the ride.
The RAF should make more videos like this.
A Big Spelling Mistake
I photographed this in a shop window in the Kingsland Road.

I thought spelling mistakes like this on products were a thing of the past.
