&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;Steam is an excellent lifting gas that provides about 60% of the lift of helium but is much cheaper. It is also a much better lifting gas than hot air at the same temperature. Steam is a very inexpensive, non-flammable, non-toxic, readily available buoyant gas. This is the basis for the concept of the steam balloon, i.e. lighter than air steam technology.  &lt;br /&gt;

==Uses / Product Ecology==&lt;br /&gt;
* transport materials over great distances for minimal cost &lt;br /&gt;
* use steam engine for propulsion. This concept was extensively discussed at Flying Kettle (link below) &lt;br /&gt;
