Must have huge flight battery inventory, and BESS battery electric
storage systems capturing daylight, to carry the 4:1 recharge:use (120
minutes of charging for 2 flights and 35 minutes of use) cycle through
the no-solar night.
Power for the project will come primarily from off-grid solar charging
systems, augmented by zero-emission ground support vehicles. Together,
the aircraft and power systems are expected to significantly reduce
fossil fuel use in flight operations and on-site support.
Yamaha’s uncrewed helicopters have been used for crop spraying in
California since the mid-2010s. The company’s R-MAX can carry 32
liters (9.5 gal) and cover 6-12 acres per hour. Smaller drones are
also in use. The Pelican 2 carries 300 liters and can cover 180-260
acres per hour. The aircraft can fly for 35 min., enough for two
flights, and recharge in 2 hr., although batteries are swappable.
