You don't need that. Just buy a bag of 100 balloons at the 5 and dime
and an air pump and that's all you need.

_Titan Exhaust Air Jack _

"...The engine is started and hot gasses are forced into the bag until
the woven PVC-coated polyester bag lifts a vehicle a full 30 inches
off the ground, which is plenty of height to get the wheels off the
ground for most vehicles. With prices starting around $120, the device
offers several advantages over traditional jacks. First, it can be
used on soft surfaces (mud, sand, or snow) where other jacks just
don't work.

I'll give 'em that, although I don't recall how many times that I've
run into that kind of problem, if ever.


Second, it easily lifts one whole side of the vehicle at
once, saving tons of time.

I wonder just how much time it saves. My floor jack, when used at the
front or rear jack points, doesn't take very long to lift both front
wheels or both back wheels high enough to get jack stands under the
side jack points, even if I only need stands on one side. When I'm
done, I just roll the jack back into my garage. Storing that device
won't be as easy.

Granted, I could take it on the road as an emergency jack, something
I don't do with my floor jack. On the other hand, I wonder if it
*requires* jack stands, something I rarely have with me on the road.

Does it stay inflated long enough to change a tire? Do have to
keep the engine running to keep it inflated? Does it have a check
valves or pressure relieve valve?

Best of all, the low pressure bag doesn't
require placement on normal jacking points so you more freedom to lift
where you want and then place jack stands exactly where you need them.

I wonder what happens if the bag comes in contact with the hot
exhaust system. I wonder if it could exert pressure on things that
shouldn't be exerted on, like brake lines, etc.

The military and emergency services have apparently been using jacks
of this type for years, so the idea isn't just full of hot air. "

This jack or "jacks of this type". That could be 2 very, very different
things.

Anyway, after typing this post, I found this, which answers some of
my questions. I won't be buying one any time soon.
