So what do we need for carbon neutral synthetic gasoline?<br>
<br>
At a recent conference a guy had worked out the numbers to suck carbon<br>
dioxide out of the air and combine it with hydrogen in a reverse<br>
combustion industrial operation.</blockquote><div><br>That's an interesting idea, but how exactly is this done?<br><br>But I agree with the premise: gasoline is far more energy dense than electric batteries will ever be. This really hit home when I was reading about the proposed specs of the upcoming Chevrolet Volt. It's 16 kWh battery, when fully charged, gives it a 40 mile range. But it has a gasoline "range extender" that does nothing but recharge the battery, attaining a range of 640 miles.<br>
<br>It's an excellent step, I think, which is what is going to be needed in an energy-scarce world, so that people can choose which way they want to fuel their cars based on existing prices. Right now, electricity is cheaper than gasoline per mile, but with a large number of electric vehicles on the road the price of electricity might go up. Ah well, no such thing as a free lunch.<br>
