I've done quite a bit of research on the CNG solution and came to the conclusion it's not as likely as electric. Here's why, it's true you can put a CNG compressor in your house but they cost about $6,000, plus or minus based on size; and they only last about 1,000 hours until they need major repairs. So you had better have a CNG station nearby. Although I hear CNG stations are popping up all over Utah, why there I don't know.

The second big problem is the size of the fuel tank. They are significantly larger than a normal gas tank. Not a huge problem but it does cut down on either space or range.

I still like plug in electric because the infrastructure is already here today with no added cost to the consumer. Other than the added cost of the cars production.

BTW Popular Mechanics said the next big gold rush will be Lithium mining. Apparently there's lots of it out there, but no one is currently ramped up for the potential need.
