Countries and places in the tropics have exceedingly hot and humid nights [1], especially during the summer months.

Trying to sleep in these conditions using only a fan is difficult and the problem gets worse if there is no power to run them.

Window AC units consume a lot of energy (5000 BTU, 4.8 amps, 515 Watts, 110/120V) and are difficult to install.

This inflatable dome insulates the person from the hot environment with walls having a 4.1 R-value. The dome is connected to a 1000 BTU air cooling unit that filters dust and removes excess humidity from the air pumped inside.

This combination provides for a clean, dry, and comfortable night sleep. The unit is battery operated and rechargeable (1000 BTU, 2 amps, 250 Watts, 115V).

This is intended for use in the home, but it can find a use in hospitals, and other indoor facilities that can't count with a continuous reliable power source.
