$CLIR a friendly reminder: the petrochemical company that ordered 26 burners is the same company that ordered the extra testing at the end of last year and is the same installation order that is expected to be in October.

$CLIR Been watching for any sign of life from this woefully weak laggard company for a long time. Saddler, former $XOM executive with very serious technical chops and many high level contacts, joining the Board, is a seriously good signal.

$CLIR Charting look: if it closes at 4.35 on decent volume, the 20 dma crosses up through the 50 dma and odds are an uptrend starts. They report on the 19th. OBV has been a bit more active than price action so it looks like someone is quietly buying the dips.

$CLIR Big deal. The money quote from Mr. Saddler — "I have followed the evolution of ClearSign's technology for many years and have been consistently impressed by its ingenuity and the value it offers," said Larry Saddler. "As a member of the Board, I look forward to leveraging my experience, industry expertise, and professional relationships to help the ongoing promotion and adoption of ClearSign's technology and to contribute to the Company's strategic growth and creation of long-term stockholder value."

$CLIR don't know what to make of this? i can't find any filing of them selling. there are filings of them in the past stating they picked up their alloted amount to maintain ownership percentage in stock offerings. there is a 13d filing on 2-19-25 then we have a 13g filing on 4-9-25 for otter capital but no reference to CLIRSPV and it shows below that they still owned. and then with the recent filing 13G of otter capital buying more shares. there is no filing of them selling which i would've thought would be required?
