To keep a bubble inflated, we use an electric fan that requires a 110V or 220V connection and consumes 0-180 kWh.
We equip all of our bubbles with the same model of motor, though the bubble may require the motor to use more or less power depending on its size.
The motor is usually installed at 5-10 meters (16-33 ft) from the bubble. However, the source of electricity may be hundreds of meters away.
Of course. This is a perfectly valid option when a conventional electric network is unavailable.
The generator must provide for the electric motor, the climate control and the lighting with a minimum safety margin of 30%.
There is no restriction as long as batteries are available for nighttime storage.
