Drones have been with us for so many years now. They are used for videos, photography, surveillance, agricultural monitoring, delivery services, and disaster response. However, a drone that can stay in the air indefinitely might be the innovation we’ve been waiting for.
Researchers at Beihang University, led by Mingjing Qi, have developed a solar-powered drone prototype that could stay airborne indefinitely.
The drone called “CoulombFly” weighs just 4 grams and is equipped with solar panels that produce a high voltage between 6,000 and 9,000 volts. This voltage is achieved through a circuit developed by the researchers, which boosts the power generated by the solar panels. The drone also features an electrostatic motor, which differs from the motors typically used in other drones and electric vehicles.
The tiny drone, approximately the size of a hummingbird, can theoretically stay airborne indefinitely. Currently, it has been able to fly for one hour during tests. The researchers are optimistic that their approach could lead to even smaller drones, similar in size to insects, that can stay in the air without needing to land.
While it is not yet clear when this prototype will move to production, the researchers are hopeful that their work represents a significant step forward. This solar-powered drone could pave the way for new types of drones that can fly for extended periods without needing to recharge.
This could be ideal for extended surveillance and monitoring without the need for frequent battery changes or recharging. Additionally, it could eliminate the need for battery replacements and recharging. What benefits do you think this technology might offer?
