Community Fund
The fund supports the towns that host these projects, whether or not the projects succeed: STEM programs, energy bill assistance, and training for the trades that build reactors. A gift carries no return, conveys no ownership, is not a security, and is subject to none of the caps on this page.
Every issuer, project, offering, TRL score and figure on this site is invented. Nothing here is an offer to sell or a solicitation to buy any security, no securities are being offered, and no money moves.
The regulatory behavior modeled throughout, including the investment limits, the accreditation tests, the intrastate residency rules and the foreign ownership screening, is a working interpretation built from public sources.
