Fantastic application. Connect your mobile with the USB cable to your laptop, install driver and EasyTether program on your mobile and use your mobile as a mobile broadband internet connection while you are charging your phone!
This is a fantastic development, when I got my Android phone I missed that kind of application and there was some hacks that could be used but nothing that worked this good.
It does not require a root:ed phone, it just works. The software will soon cost a few bucks but it is well worth it if you want to be able to use your phone as a gateway to the internet.
It also uses the phones built-in firewalling capabilities protecting your laptop from attacks from the outside by filtering various protocols. You might even filter UDP ports (except DNS requests) if you like.
One of the biggest problem of using electrical (battery powered) cars is the problem of charging them. The amount of energy needed for a normal trip to work would require several hours of charging the car, it has been estimated to somewhere around 8 to 12 hours of charging. This is of course very different from filling the car with petrol which takes a couple of minutes and the battery charge time of 8 hours or so would work if you charged the car over night, went to work, charged it while working and then returned home.
The problem here is of course obvious – I think a lot of people want to use their cars shopping and transporting and that makes it much harder, not to mention taking a longer trip that is more than say an hour or so that would be difficult in an electric car this way. Imagine visiting even close by relatives and having to stay the night because you have to re-charge your car battery over night just for the trip home. Someone suggested that there would be ”battery stations” where the whole battery pack could be changed in the car, removing the flat battery and inserting a fresh one and then this way save the charge time. Not very practical however because you may imagine the stack of batteries required to fill even a fraction of the energy need normal gas stations fill?
But there is a solution now, the Swedish paper ”Ny Teknik”, new technology, reports about scientists at MIT in the US having come up with a new type of battery that can be charged in about 20 seconds which is incredible. The paper is scarce on the details for it but it is a definite improvement and if this could go into serial production that could save the battery powered car from being nice but not very useful!
One problem they note however is that house-hold electrical outlet would not be able to deliver the charge current necessary, that would require high amp industrial connections which could be put at special ”charge stations” but not really practical at home – it would require changing the electricity system completely between the transformer and the house and the electrical grid is not built to take such currents from ordinary houses.
So a cross between these technologies seems the ideal, a full charge may take say 5 hours or so when at home, over night and at the ”e-station” you can fill her up in about 20 seconds and then continue driving. Enough of these charge stations along the roads and the problem seems possible to solve actually.
It sure is an interesting technology, something I have waited a long time for.
