This startup wants to build a nuclear fusion reactor — on a boat

From floating ideas to nuclear fusion on a boat! 😊

We have been waiting for how many decades for nuclear fusion to become a source of energy supply? It is just around the corner!

However, machine learning & AI may indeed make a difference like nothing before.

"There’s only one fusion device on earth that has been able to meet a key scientific threshold, but Martime Fusion CEO Justin Cohen is already preparing to put a fusion reactor on a boat. ...

Thanks to advances in AI, computing, and superconducting magnets, fusion power is closer than ever to commercial reality. It’s increasingly looking like fusion is more a question of “when” not “if.”  ...

To flesh out its concept and start building parts for its first reactor, Maritime Fusion has raised $4.5 million in a seed round ..."

"... Since then we’ve stood up our HTS magnet lab in San Francisco and have been rapidly iterating and testing prototype cables and magnets. Below is a snapshot from a recent bench test where we ran 5kA through our HTS cable SHIELD —Superconducting High Integrity Energy Link & Distribution— with liquid Nitrogen as the coolant.

In parallel, we’re advancing the physics basis for Yinsen, a low–power-density HTS tokamak and are excited to be partnering with both Columbia University via a Sponsored Research Agreement, and the Department of Energy’s DIII-D National Fusion Facility as a user to run experiments focused on our pulse scenario. ..."
