Abstract: A portable cooling system includes an air cooling unit, a housing enclosing the air cooling unit, an output port, and flexible tubing. The air cooling unit includes an air intake, an air cooler, an air output, and a blower. The blower is configured to drive air from the outside through the air cooling unit. The air cooler is configured to cool air received through the air intake. The cooled air is then discharged through the air output by the blower. The output port is connected to the air output for receiving the cooled air. The flexible tubing includes a first end that is coupled to the output port and can be used to deliver the cooled air to a portable personal shelter.

Abstract: A vehicle having an electric hybrid power system is provided. The vehicle includes an electric motor drivably connected to one or more ground engaging wheels. A battery pack stores electricity to power the electric motor. An engine is drivably connected to the wheels with an alternator connected to the engine for recharging an accessory battery. The alternator has at least a voltage output range of between approximately the standard output voltage of the accessory battery and the standard output voltage of the battery pack. In accordance with the present invention, a mechanism for electrically connecting the alternator to the battery pack is provided such that the alternator alternatively recharges both the battery pack and the accessory battery.
