His invention, dubbed the Mach-effect gravitational assist (MEGA) drive, makes the extraordinary promise of a propulsion system that relies on nothing but a source of electricity — no heavy combustion fuel necessary, as [*Wired* reports in a fascinating new feature](). The idea is to accelerate slowly, but over a very long period of time. According to Woodward, a spacecraft with a MEGA drive could eventually reach velocities approaching the speed of light, with the help of an onboard nuclear reactor to supply decades worth of electric power. The MEGA drive relies on Mach's principle, named by Albert Einstein himself, which claims that inertia is related to distant gravitational effects. As an object's energy changes, the very matter of space and time changes around it as well, a controversial an interpretation of Einstein's famous mass-energy equivalence principle E=mc². In other words, according to *Wired*, if part of an object — in the case of the MEGA drive, parts of tiny piezoelectric disks — were to simultaneously change its mass and energy state, it could theoretically start accelerating. Woodward's work on his MEGA drive has been ongoing for over thirty years. He was even [awarded funding]() through NASA's Innovative Advanced Concepts program in 2017. With the grant money, Woodward and his collaborators have even designed a conceptual uncrewed spacecraft called SSI Lambda, an unusual-looking craft that houses an array of about 1,5000 scaled-up MEGA drives. More recently, Woodward's latest MEGA drive produced far more thrust than all his previous prototypes. "I was shocked at the huge increase in measured force," Hal Fearn, close collaborator and physicist at California State University, Fullerton, told *Wired*. Yet other researchers are still skeptical of the novel device. "I'd say there's between a 1-in-10 and 1-in-10,000,000 chance that it’s real, and probably toward the higher end of that spectrum," Mike McDonald, an aerospace engineer at the Naval Research Laboratory in Maryland, told the magazine. "But imagine that one chance; that would be amazing," he added. "That's why we do high-risk, high-reward work. That’s why we do science." Woodward and Fearn are now planning to send a demonstration of the device into orbit to test how it fares in space. **READ MORE:** [Gravity, Gizmos, and a Grand Theory of Interstellar Travel]() \[*Wired*\] **More on interstellar travel:** *[New Experiment Will Test EmDrive That Breaks the Laws of Physics]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
