Early versions of the quadcopter worked pretty good, but, were not able to sustain camera weight. They had a tendency to crash with the added weight. One advantage, however, was the ability to fly without a battery...

How Big Can a Solar-Powered Drone Be?

This means there is no call for for a battery to temporarily store energy—which is fine, since that would add mass. But how much power can . How big is this quadcopter? How large are the rotors? What about the size of the solar panels? What if someone
Solar-powered quadcopter can reportedly "fly for hours"
08/21/18 ,via New Atlas
We've heard about "solar-powered" quadcopters before, in which their battery is charged by base-based photovoltaic panels. Now, however, engineering students have built a copter that draws its power directly from onboard solar cells, clearly

Solar-powered quadcopter can reportedly "fly for hours" - New Atlas
Developed by a disciple team from the National University of Singapore (NUS), the drone is built mainly from carbon fiber, tipping the scales at just 2. 6 kg (5. 7 lb). It has no onboard battery or other vigour-storage system, but is instead equipped with an array of 148 silicon solar cells, giving it a total skin area of approximately 4 square meters (43 sq ft). It is hoped that this proof-of-concept model could ultimately lead to solar-powered quadcopters that might be used as power-providing "flying solar panels" at disaster sites, or that could be used for tasks such as surveillance and photography. For some applications, the summation of an integrated battery would let the aircraft keep flying at night or in cloudy conditions. "Our aircraft is extremely lightweight for its largeness, and it can fly as long as there is sunlight, even for hours," says Danner. "Unlike conventional quadcopter drones, our aircraft does not rely on onboard batteries and for that it is not limited by flight time. Its ability to land on any flat surface and fly out of the ground effect in a controlled way also makes it becoming for practical implementation. Source: newatlas.com
Could hydrogen stimulate cells be a solution for poor drone battery life? - We Talk UAV News (blog)
WeTalkUAV produces non-stop articles and videos expounding the virtues of drones and showing you all the ways the cool and interesting ways they are changing the domain. One of the biggest drawbacks of this technology, however, is the poor life of their lithium ion batteries. Few drones, whether commercial or consumer, can fly for more for longer than 15-30 minutes. There are models expert of longer flight times but they tend to be far more expensive and primarily exist in the commercial arena. Many disputing implications stem from this poor battery life fact. it’s a massive buzz kill than having your drone controller intimate you’ve only got a few minutes of flight time left, particularly when there are no spare batteries round. For the commercial operator: having to replacement batteries regularly takes up a lot of time that could and should be spent on the job at hand. So why don’t they just add more batteries to existing drones. Unfortunately, because batteries better the weight of any given UAV, the drone needs to generate more power to stay in the air. So – unless you can produce much lighter batteries, it makes zero mother wit to add additional weight in the form of batteries to our current generation of drones. How can hydrogen help. Hydrogen is the most abounding in element in the universe and we’ve had the ability to power cars with hydrogen for decades. Unlike a battery, which stores power, a hydrogen tinder cell is, in essence, a device that uses chemical reactions to generate electricity. Hydrogen fuel cells synthesize hydrogen and oxygen produce water and energy in the form of electricity. Hydrogen cells are very environmentally close, producing only water as a byproduct. Last year, a Singaporean-based company produced a hydrogen-powered quadcopter that could continuously for four hours. They managed to discern this particular drone for an astonishing four hours. Lead researcher, Andrew Gong told DroneLife : “Hydrogen power provides much greater collection and endurance compared to existing small electric unmanned aircraft. In the future, this may be useful for extended-duration inspection or scrutiny tasks, such as surveying large agricultural properties or inspecting pipelines and other infrastructure. Are there other methods that keep drones flying for longer. One way to hide drones in the air for a much longer time is to tether them to the ground. Being constantly attached to a power supply equals a big spread in flight time. On the other hand, being tethered gives many limitation, not least of which is you can kiss the portability of your drone goodbye. A rope long enough to allow the drone to fly hundreds of meters is probably going to be a bit unwieldy. What about solar power. Couldn’t it be an numberless free source of energy for drones if they had little solar panels. We should continue to develop the solar powered drone technology but it’s unimaginable to be viable, at least given current capabilities. If hydrogen fuel powered drones are so great, why aren’t they more renowned. There are several reasons for this. Firstly, lithium ion technology has continued to improve over the past decade, although. Source: www.wetalkuav.com
NUS engineers contrive drone powered by solar energy - Connected to India
A crew from the National University of Singapore (NUS) has developed a quadcopter drone that can be powered solely by natural sunlight. A first in Asia, the coeval prototype has flown above 10 metres in test flights – higher than a typical three floor building, NUS said in a press release. The solar-powered drone utilised solar power with no battery or other dash storage on board. It was developed as a student project under the Innovation & Design Programme (iDP) at NUS Faculty of Engineering. Weighing only 2. 6kg, the quadcopter can remind one of-off and land vertically without a runway. “Our aircraft is extremely lightweight for its size, and it can fly as long as there is sunlight, even for hours,” said Associate Professor Aaron Danner from the Division of Electrical and Computer Engineering at NUS Faculty of Engineering, who supervised the project. "Unlike conventional quadcopter drones, our aircraft does not rely on on-provisions batteries and hence it is not limited by flight time. The solar-powered quadcopter drone can be controlled by remote check or programmed to fly autonomously using a GPS system incorporated into the aircraft. Batteries can be incorporated to power the aircraft when there is no sunlight. Source: www.connectedtoindia.com
