![]() ![]() 2023 Tech seemed a focused way to drain the artist’s expressive self from a work of art, the subject of an emotional inner life having been wrung dry by the narrow, droning longevity of Abstract Expressionist painting. Michael Rechtshaffen, Los Angeles Times, 2 June 2023 Mercedes’s contribution to this sonic uprising is a clanging, droning soundtrack drawn from the sounds made by throwing bullet casings into a crucible. David Wharton, Los Angeles Times, 22 June 2023 Echoing those visuals is a soundscape of chirping cicadas and falling rain, paired with an insistent, droning score by composer Shida Shahabi, heightening the increasing heaviness in the atmosphere. “Hydrogen can mean 4-5 hours of flight time, so it’s a big jump it’s a new capability of what we can do with payloads and flight time.Verb Bombers droned across the night sky as soldiers scrambled onto the beachhead, taking cover behind huts and clusters of palm trees. “Imagine 30 drones advancing in a swarm and if they don’t have to come back every 30 minutes but in a few hours,” Levinson said. It describes the H2D55 as the first hydrogen-powered drone for commercial use, and said its working with an unnamed global parter to roll it out in the second half of 2023.” Like most Israel companies in the defense sector, HevenDrones doesn’t disclose its other customers but says it has drones “flying on two continents.” The battery-powered drones are already operational and the hydrogen-powered drone has passed a proof of concept, with the company expecting to deliver the first of these drones to the market in the next couple of months. CEO Levinson says he sees growth, resources and also an “innovation mindset” in the UAE that has potential for “strengthening the region and that is a key priority. In the wake of the peace deal with Israel, called the Abraham Accords, Israeli companies have been appearing at IDEX. HevenDrones sees the potential for partnerships in the UAE. “I was a combat commander, we find ourselves as military people in difficult situations and having flying robots that can fight the war with us and carry our bags or fly in a few hundred feet ahead of us with thermal cameras and eliminate risks, that can eliminate risk to our soldiers.” “The hydrogen tailored factories has opened a new capability and new generation…if you can imagine the changes on battlefield for instance,” said Levinson, a former soldier. It’s planning to open an office in Miami says it is starting to see global growth in partnerships. The company has tested these energy sources to make them safe, subjecting them to small arms fire and also dropping them from a height. Hydrogen fuel cells can be swapped out, like a battery, and armies can bring fuel to a base to portably refuel tanks, and one can have an electrolyzer in the field, with water and electricity, to create the hydrogen fuel source, according tot he company. to customize an energy source for the drones. HevenDrones worked with hydrogen fuel energy developers in New York state and the U.K. ![]() “Essentially we create energy in the sky with a hydrogen tank and cylinder that is highly pressurized and it makes the gas into energy and that goes into a battery that powers the drone,” Levinson said. The company worked closely with Israel’s Ministry of Defense on this project over the last year and a half. ![]() Levinson says that using hydrogen fuel enables a longer flight time and a better energy-to-weight ratio. ![]() This triangle of size issues has kept smaller drones from achieving long ranges and endurance in terms of flying time. One limitation drones face is that a larger payload means a drone needs more battery power, and then the weight becomes larger, meaning the drone needs larger engines. ![]()
