Sunbird Fusion Propulsion Rocket Engine

Just did a little digging and looks sus -- see https://news.ycombinator.com/item?id=36693222

> EDIT: It looks, at best, like a vanity project, and, most likely, a scam. The founder is a television personality [1]. Article claims the firm “currently produces chemical and electric propulsion systems for the aerospace and defence sectors,” yet they somehow have fewer than double checks £5,000 in fixed assets [2]. They hired this real estate and art advisory dude to raise capital for them in 2019 [3][4], who apart from two other individuals [5], is the main outside shareholder. The Princeton Propulsion Systems they’ve “partnered with” is crowdfunding $100,000 [6]. (The latter look marginally legit—I assume Pulsar signed a non-binding LOI with them. That or they’re the £300,000 [2] current liability Pulsar raised money from the real estate and art advisor this January [7] to extinguish.)

I'd settle for fission power, a known rocket technology:
