Tesla unveils its Powerwall, a revolution in the making

If you consume as little as electricity as you can and have solar panels installed, you are just one step away from being independant from coal and gas fueled utilities. This step might come sooner than expected thanks to Tesla.

Hydrogen is ” an incredibly dumb ” car fuel

That’s Elon Musk’s opinion so that must be true. Tesla’s genius founder put yet another nail in the hydrogen coffin and stated what we knew all along : hydrogen is a technology that may well be too complex to ever be significant.

Envia, a battery breakthrough for electric vehicles

Electric vehicles suffer nowadays from two main problems : limited range and expensive price. But both problems could soon be solved if Envia Systems, a California-based company succeeded. To Climate Progress :

” Envia says its new manganese-based cathode design allows lithium cells to store almost three times the amount of energy per charge than today’s commercial lithium-ion battery packs. ”

But there is more :” The cost of cells will be less than half  (…) of cells today “. Yes, Envia could bring batteries that would triple the range while being half as cheap as today’s models.

Electric cars batteries’ prices to drop by 2015

Now having to commute by car to get to my new job I can’t wait for having an electric car. But current prices are way to high for me to afford one. Luckily, this might change quite quickly. To AutoBlog Green : ” U.S. Energy Secretary Steven Chu estimates that plug-in vehicle battery costs will … Read more

An electric car goes 1,600 km on a single charge

Is this the car of tomorrow ? Gas 2.0 published an article on an electric car that did more than 1,600 kilometers (a thousand miles) with a single charge. The top speed was less than 50 kilometers per hour. As they note : ” The record for longest drive ever in a battery-powered vehicle (no … Read more

Better Place going to China

Do you remember Better Place, the great electric car project ? To Ecogeek : “Better Place has entered into an agreement with Chinese utility China Southern Power Grid to bring their battery swap stations to the Asian country.” “(…) Better Place founder Shai Aggasi sees this partnership leading to a shift in Chinese EV manufacturing … Read more

Electric cars are the next growth engine

Thomas L Friedman is one of the op-ed columnist of the New York Times. I really liked the vision he is offering in his latest book, Hot, Flat and Crowded. I have to admit I feel the same about his latest column, Their Moon Shot and Ours.

There, Mr. Friedman shows how China is going full speed ahead on electric cars and vehicles, a technology he calls ” the next industrial growth engine “. Indeed, they could revolutionize tomorrow’s world.

Cars produced locally powered by electricity also produced locally may indeed bring a complete paradigm shift with peak oil, the worst economic crisis in decades and climate change.

Battery breakthroughs for electric vehicles

electric-car-charge-plugMany are working on extending the range of electric cars. Here are three of them. Firstly TreeHugger believes that replacing the  graphite electrodes in lithium-ion batteries with silicon nanotube electrodes,would multiply the range by ten.

ArsTechnica notes that carbon nanotubes in ultracapacitors ” may make sense in electric cars, even if it can’t store as much as a battery.” Thirdly, IBM is launching a project to enable electric cars to have a range of 500 miles (800 km).

Extending the current range of electric vehicles and cutting the costs of batteries are the two necessary steps to allow mass market commercialization.
