Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
The big question of course is the Lithium battery system itself.
Eberhard and his team looked far wide to find the best battery system
design possible. Even before the current notebook recalls involving
Sony Lithium Ion battery packs, the Tesla team were aware of the
potential fragility, heating and charging issues of the technology.
However, Tesla insists that the issues have been solved. There's a
liquid cooling system and all the issues with charging and discharging
are computer controlled. Batteries are arranged in blades, so that if
one fails it doesn't degrade the system.
According to Tesla, Lithium Ion technology is already powerful enough
now to be used for transport in a practical sense but it is continually
improving and will one day completely outstrip fossil fuels for storage
capacity. In fact, in an interview with green motoring site
AutoBlogGreen, Tesla chairman Elon Musk says the battery pack in the
Tesla Roadster stores so much energy that it could used to power an
entire house during a power outage. What's more, you can leave your car
parked on a hot or cold day with the climate control on without any
problems
Most renewable energy advocates agree that a key weakness with their
favoured solar and wind power electricity generation solutions is
energy storage. However, as far as at least one company in Silicon
Valley is concerned, the energy storage problem has been solved - at
least as far as transport is concerned.
