The penguins enjoy snow, made on site. Air is filtered to 3 microns. Each snow-cat weighs 3 tonnes, and is electrically powered by a 24V battery which is recharged every night. Without charging, a battery will last two days. Each snow-cat is controlled by its own onboard computer and electronic sensors, which confirm its position and ensure nothing is in its way.
