Cram Energy into an Electric Car
You're smart, maybe even a bit geeky. You keep up with the latest technology; maybe even consider yourself an early adopter. You're sold on electric cars, and maybe you even have one already. Those little tires, those rounded bodies, those silent approaches that allow you to sneak around town.
Your mom, though, she is none of these things. She uses the browser that came with her computer, for Turing's sake. An electric car is beyond her. She'll get stranded. She wouldn't be able to visit your sister in the next state. What if she wanted to take off for an afternoon at the beach with her friends from church? So what if she's never done it before.
Your mom's dreams can come true without emitting a single molecule of carbon dioxide, thanks to Envia System's most energy-dense battery ever. It's a lithium-ion battery that packs twice as much energy per gram as the batteries in cars today. To get all techy for the geeks, the battery uses an anode made of silicon wrapped in little graphite jackets to boost performance without causing battery meltdown after one charge cycle, which is what usually happens with silicon in batteries.
They've also made the battery cooler (no more bursting into flames, a la MacBooks circa 2007) and cheaper, and they'll fit into the slots automakers are already building for the current crop of batteries. Not that your mom will believe you.
