Various combinations of solid and liquid chemicals proposed as sources of hydrogen and other gases for inflating lighter-than-air balloons. In all cases energy used to propel balloon upward or downward comes from temperature differences in planet's atmosphere itself. Phase changes and/or reversible chemical reactions used to vary quantities of gases in balloons as functions of pressure and temperature and, as functions of altitude: provides means to control altitude of balloon.
