New Nanowire Battery Holds Great Promise

ScienceDaily reports on new nano technology that could revolutionize the lithium battery strength. They report:

Stanford researchers have found a way to use silicon nanowires to reinvent the rechargeable lithium-ion batteries that power laptops, iPods, video cameras, cell phones, and countless other devices.

The new version of the battery was explained by Yi Cui. He explained that 'a laptop that now runs on battery for two hours could operate for 20 hours, a boon to ocean-hopping business travelers. "It's not a small improvement," Cui said. "It's a revolutionary development."
The greatly expanded storage capacity could make Li-ion batteries attractive to electric car manufacturers. Cui suggested that they could also be used in homes or offices to store electricity generated by rooftop solar panels. "Given the mature infrastructure behind silicon, this new technology can be pushed to real life quickly," Cui said.

Now we have to ask the question: how long before it will be ready for the automobile? It seems to me that replacing the conbustion engine is of paramount importance if we wish to save the planet. How will Big Oil react to this potential new energy source?

lots of questions...
