<p>The world needs a fundamentally new source of clean energy to meet our growing energy demands and combat climate change. Scientists have been studying fusion for decades and have made significant progress, but have yet to achieve its potential as a commercial power source. However, its promise has continued to drive interest with the understanding that successfully deployed fusion power would transform the world&rsquo;s energy landscape.</p>
<p>Commonwealth Fusion Systems (CFS) was spun out of MIT's Plasma Science and Fusion Center to leverage the decades of fusion research combined with the innovation and speed of the private sector. Supported by the world&rsquo;s leading investors in breakthrough energy technologies, the CFS team is uniquely positioned to deliver the fastest path to commercial fusion energy. CFS has assembled a world-class team to design and build fusion machines. This team includes experts in magnets, manufacturing, and plasma physics dedicated to the mission of delivering clean, limitless fusion power to the world.</p>
