A. Simi Valley Acorn, 25 June 2010, "Still no official cause of explosion on Easy Street", by Carissa Marsh [web: https://www.simivalleyacorn.com/articles/still-no-official-cause-of-explosion-on-easy-street/]

  • The person killed on 17 June 2010 was Tyson Larson, 28, the co-inventor, described as "a 28-year-old inventor working in the lab of his family's business". This answers the open point in claims.md item 6 (the Ventura County Star article in the folder did not name the victim).
  • Cal/OSHA spokesperson Krisann Chasarik: the victim "was processing a fuel mixture when it exploded". Cal/OSHA was investigating; it expected 3-6 months.
  • Ventura County Fire Capt. Ron Oatman: no fire was found; the roof of the four-unit building at 480 E. Easy St. was partly or totally collapsed. Fire department ruling so far: "accidental but undetermined". Medical examiner: death from multiple blunt force injuries.
  • December 2008 incident: a high-pressure tank used to make fuel from water "imploded due to mechanical valve failure"; Larson had minor to moderate burns. The operation then moved from N. Shasta Way to Easy Street.
  • Present on 17 June 2010, per Cal/OSHA: Timothy Larson, founder of Realm Industries, "also called Realm Catalyst", and his two sons Tyson and Tim.
  • The patent mention: "applied for a patent in April 2009 for an alternative fuel engine" (matches PCT/US2009/039556, filed 3 April 2009; see google-patents note).
  • Biography: Grace Brethren High School, Simi Valley; degree from UCLA.
  • The Realm director did not return calls.

B. Ventura County Star, 21 June 2010, "Simi business in fatal explosion originated with failed N.Y. venture", by Adam Foxman [web: https://archive.vcstar.com/business/simi-business-in-fatal-explosion-originated-with-failed-ny-venture-ep-368507413-349112401.html]

Main source for the company's origin. Sources quoted: AUSA Kevin Dooley (the prosecutor, an interested party in the fraud case); Cal/OSHA; a Purdue chemist. - Origin: co-inventor William Stehl formed companies (including BGX Technologies, run from Saranac Lake, NY) that, from 2001, raised money for a process he said made cost-efficient energy from water. He was indicted in March 2010 in the Northern District of New York with co-defendant Richard Rossignol for conspiracy to commit fraud (more than 300 investors, more than $6 million), plus tax charges for Stehl. Both pleaded not guilty at that time. - Timothy A. Larson (Tyson's father, Realm's founder) was one of the investors. He is not accused of wrongdoing. Dooley: when BGX failed in late 2005, Larson "believed in the science" and paid to ship BGX Tech's equipment to California, where he set up Realm Industries with his sons Tyson and Tim. Stehl came to California as an unpaid, later paid, consultant. - Tyson Larson: 2004 UCLA graduate, B.S. in biology; began working on Stehl's process. Cal/OSHA called him Realm's head chemist. - Stehl's credentials (per Dooley): high-school graduate who attended several colleges without a degree. - The prosecutor on the science, quoted fairly: "We're not alleging that this is some kind of fraudulent scientific process ... the issue is the commercial viability". The indictment "makes no judgments about the validity of the science". - Authorities on the cause: a pressurized container "being used to heat water in an apparent attempt to break hydrogen and oxygen apart". This is the authorities' characterization, not the inventors'. - Present at the fatal explosion: Tyson Larson, Stehl, and Francisco Torres. Stehl and Torres got out without significant injuries; father and brother nearby with minor injuries (Cal/OSHA). - Dissent: Dan Raftery, chemistry professor at Purdue, from news reports and the patent application: "I don't believe this patent application really is viable"; it appears to be a form of electrolysis, and large-scale electrolysis could create the conditions for a big explosion. This is one outside expert's view, given to a reporter without inspecting the apparatus. - "To date, no patent has been issued" (true on 21 June 2010; US 7,793,621 was granted on 14 September 2010). - Not opened (next run): VC Star 18 June 2010, "Authorities identify man killed in Simi Valley explosion; death ruled accidental" (https://archive.vcstar.com/news/authorities-identify-man-killed-in-simi-valley-explosion-death-ruled-accidental-ep-368552822-349150321.html/). Its snippet mentions the March indictment and co-defendant Richard Rossignol.

  • Los Angeles Daily News, 17 June 2010, "Man killed in Simi Valley explosion" (28-year-old killed at Realm Industries, "an alternative fuel research company").
  • Reddit r/technology thread (about 16 years old) relaying a PESN (Pure Energy Systems News, pesn.com) article: "Explosion at California water fuel research company kills inventor"; the same PESN text was reposted on 911forum.org.uk under "Mysterious Deaths of Inventors". The PESN original was not found by site search (see sites.md); retry via the Wayback Machine.
  • Lab Safety Institute memorial wall and its PDF "One Hundred Years of 'Progress'" (2021) list Tyson Larson, 2010, as a lab-accident death ("hydrogen explosion"; the town is misspelled "Sumi Valley").

Bearing on the claims

  • Claim 6 (independent record): victim identified as the co-inventor himself. The cause was undetermined at the time. Cal/OSHA found that pressurized containers failed (see the 2011-2012 notes).
  • Claims 2-3: the authorities and an outside chemist describe the process as electrolysis or hydrogen production. The inventors' 2009 PCT text also admits H2/O2 as a possible product (google-patents note).
  • Absence of evidence: Stehl's process had been pitched to investors since 2001, but no independent test of it appears in these reports. The prosecutor explicitly did not challenge the science.
