No, you blow to compress air, you suck to decompress air.

Nuclear, solar, wind, hydro

Why are you responding in such a condescending tone?  Was my reply in any way as rude?  Do you hold all of your internet conversations by talking down to your fellow contributors? You don’t know who we are; you don’t have any right to reply like that. Grow up. Keep your “gold stars” and “walk step by step for you’s” to yourself. If you can’t be civil to strangers, then keep your opinions to yourself. 

The compressed gas that “it” uses is compressed with electricity, yes.  

…and yes, I realize the gas is not compressed onboard, and that the car doesn’t accomplish this on “its” own.  I’m sorry my simpler phrasing upset you so. If I say “the car uses a DC power supply,” I don’t mean to imply that the car connects “itself” to the charger either. “It” (the car) utilizes a compressed gas source, which was electrically powered. 

Sure, that minuscule amount of electricity could be generated by way of fossil fuel power plants, but seeing as how this is a Tesla demo, probably a one-off (assuming Musk is lying about delivering - as he usually is), and Tesla’s “gigafactory” uses a massive solar farm in addition to the local power grid (which may include fossil fuels), it’s nearly a wash. A tiny “carbon footprint,” if any at all. Hell, manufacturing those bottle lids probably generates a larger carbon footprint. 

Like [@DJKJuicy@sh.itjust.works]\ said, there are plenty of other aspects to this to make fun of.  Arguing that the compressed gas is somehow contributing to its global footprint is stupid. But then, so is arguing with strangers on the internet.
