So why all the flap about keystone?
Sam Carana has brought to my attention another company, which has already achieved 400 Wh/kg in a lithium ion battery, and has the stated goal of a 300 mile range at affordable prices. Envia Systems' battery installed in a Nissan Leaf would extend the Leaf's range to approximately 170 miles.
Of course, if you're one of those folks, who is used to paying upwards of $60K for a car now, you should look at the Tesla S, which already has a 300 mile range.
As many of you will know, I bought a Chevy Volt in July of last year. I have been very happy with this mostly electric car (I drive about 95% on electric energy at about 20% of what a gas car costs). But with EVs advancing as rapidly as they are, in the back of my mind a nagging question is emerging - did I jump too soon? Perhaps not. By the time I'm ready to trade the Volt, it looks like I'll be able to afford that 300 mile EV.
Here's the thing, though - if an affordable, 300 mile electric vehicle is "just around the corner," why in God's name are we "debating" an oil pipeline from Canada to Texas?
