My brother just wrote an interesting post about hybrid cars saying how the current measures for economy we see aren’t really effective.
He has a good point, but also what worries me about hybrid vehicles is the environmental impact of them over their life-cycle. Most hybrid vehicles have batteries, these batteries are often made with toxic chemicals and heavy metals. How long do the batteries last? What happens with them when they are expired? I know my laptop battery, after two years of heavy use, is now at half its’ capabilities so how long will the very expensive batteries in a hybrid vehicle last?
Apparently if the KERS (Kinetic Energy Recovery Systems) used in F1 was applied to London Underground they would use 50% less electricity, but like in hybrid cars where would this charge get stored? Certainly not with conventional batteries because they can’t absorb charge quickly enough and have trouble with the discharge power for fast acceleration; that said Altairnano and Hitachi both claim dramatic improvements in this area. Super capacitors suffer leakage so this wouldn’t be very efficient for a standing vehicle. One of the most effective stores of energy is actually mechanical storage because conversion losses can be reduced substantially and this would be the best solution for London Underground. Fit a large spinning mass under the train and store the energy recovered in breaking deceleration directly on the mass, then couple the mass to the drive train during acceleration to give it that extra boost.
However, we can’t all carry round a huge mass in our cars because it will have a worse affect on the efficiency of a car compared to the constant stop-start of the Underground train.
Some new technology is needed and I don’t know where it will come from but, like mechanical storage, I think we will be surprised and it will come from the past!
On the business social network LinkedIn the question was posed by Steve Cohn of T-Mobile:
Can TV be replaced as a form of entertainment, and with what ?
And amongst the other answers I wrote the following which I shall share here:
“To provide some background: I work for a company that makes Digital Television receivers, I previously lectured at a specialist college in broadcasting and I also worked for the BBC (among other broadcast companies).
After all this, I don’t own a TV and the result is that both my partner and I couldn’t be happier. This isn’t to say we don’t watch ‘TV’, we watch some downloaded and on demand content, however unlike most peoples experience with television we are not passive viewers. We actively seek out that which we would like to watch and if nothing appeals we don’t watch anything we do something else.
I think the visual medium has worked for so long (theatre, graphic novels, film and TV) that it will never be replaced because it is the mirror of our lives. However, with the improvement in diversity of choice and the move away from the linear viewing experience (through DTR/PVR time shifting) is creating a new generation who don’t just watch what they want but when they want.
One thing however that will sustain is the fact that for the majority of people (not really represented in the demographic reading here) they are happy with the passive experience because it means they don’t need to think. Many people do like to be told what is good, what is right and what to do. They come home, turn on the TV and just accept that which is fed to them and they are themselves complicit in accepting this.
Fortunately this is being supplanted by the non-linear experience where popularity is dynamically decided by the social network and while consumers might only limit themselves to routinely watching the top-ten selection there is still a greater degree of individual influence and choice. Plus, through the growth of linking and “digg”ing you are seeing ‘playlists’ being composed again and what is effectively the return of the ‘mix tape’ through the sharing of content selection as self-expression.“
I welcome any comments on my reply or the question in general.
The news on the BBC is talking about how it would be illegal to take the timber that has fallen from a Russian cargo ship recently and is heading down the English Channel. I grew up in Dover and coming from a port family I know very well that it is legal. Because the product is not buoyed to mark it’s ownership and thus is flotsum and may be collected by anyone who finds it. However they must notify the Receiver of Wreck to avoid being accused of theft.
Once it is lost at sea then first come first served.
I have just found this cool tool on DigitalSpy and I have to say it is rather good. There is rarely a substitute of a site survey, but Google earth/maps has come to my rescue in the past.
My boss announced this morning that he had broken his Samsung smartphone, so he needed a new phone and wanted to know what his options were. Everyone in the company uses Blackberry phones except the Korean staff because UK Blackberry phones don’t come with Korean support.
This also bugged me because I get emails from my Korean colleagues and often I can’t see who has emailed me (by recogition of the characters) it just comes up as black blocks (or rather did come…).
