The world needs a new source of energy, an unspillable source.

Is there anyone working on a Compressed Air – Electric Hybrid Engine?

I am seeing a lot of articles talking about electric vehicles (investment, research and development, etc.), of which I am in favor of but it seems like we are putting all of eggs in the EV basket. I believe that we also need to investigate other forms of energy to power our vehicles as well. Are there any organizations out there that are conducting research into more hybrid technologies?
