Reactor Construction Milestone
- CFS installed a 75-ton stainless steel Cryostat Base, the foundation of its Sparc fusion reactor.
- This marks a transition from building support facilities to constructing the reactor itself.
Clean Energy Solution
- CFS, backed by Bill Gates, aims to create a commercially viable fusion power reactor.
- Fusion power offers a clean energy solution using hydrogen fuel derived from seawater.
Sparc Reactor Timeline
- CFS's Sparc reactor is expected to be operational by 2027.
- If successful, it could be the first tokamak to produce net positive energy.
