The question I’m asking here is what should we do as engineers?

Talk about it and spread the word to others that this is impossible to do.

There's also some interesting discussion here, mostly to the tune of "it won't work":

Thank you for pointing that out. It was interesting reading.

I was hoping that someone in this community would know someone in indegogo responsible enough to say wait a minute, this is not plausible. I took a look at indegogo's terms of service and found only this:

"If the Campaign is claiming to do the impossible or it's just plain phony, don't post it. "

Which is pretty weak.

But I suppose the old saw that 'a fool and his money are soon parted' still applies in the crowdfunding world...

And here's a -real- battery powered CPAP machine, taking a laptop-type lithium ion battery:
