A crowdfunding campaign aimed at getting a firefighting drone off the ground has drawn criticism, after it was revealed the MicroMultiCopters Aero Technology (MMC) machine would "break the laws of physics". In their promotional video, the company states the USD 70,000, hydrogen-powered drone can carry “up to 100kg”, but hadn’t taken into account the weight of the hosepipe, the water inside or the conditions of a real fire. Backers have - so far - steered clear of the campaign, which features no working prototype and only 3D renderings of the drone, something Kickstarter has banned.
