These days I am reactivating this project in my garage in Sun Valley.
I found this spin-off on the NSF web yesterday, Novenber 21, 2007! WOW!!! $324,981

ABSTRACTABSTRACT National Science Foundation Proposal Number CTS-0553571
Principal Investigator Warrier, Gopinath Affiliation University of California-Los Angeles
Proposal Title Heat Transfer in Fluids at Near Critical Pressures: Experiments and Mathematical Modeling
High pressure fluids are increasingly being promoted as heat transfer media in a number of thermal and chemical processes such as cryogenic cooling systems, thermosyphons, and large Supercritical Water-Cooled Reactors (SCWR). However, due to the rapid change in fluid properties close to the critical point, the experimental results have yielded both heat transfer enhancement and deterioration. The results for these contradictory results are not clearly understood. In this fundamental study, the heat transfer mechanisms involved during natural convection and boiling from microscale heater elements at near-critical pressures will be investigated. Both Schlieren photography and Particle Image Velocimetry will be employed. Models/correlations suitable for design purposes will be developed based on the experimental data. In addition to the experiments, numerical simulations using Direct Numerical Simulation (DNS) will also be performed. The temperature and velocity data obtained in the experiments will be used to validate the numerical simulations.
Intellectual Merit: The proposed study will greatly advance the basic understanding of heat transfer in fluids at pressures near the critical pressure. The knowledge gained will provide researchers, in academia and industry, with a better understanding of the process. Potential innovative applications of this knowledge include miniature thermosyphons and heat pipes, cryogenic cooling systems, and in a broader sense SCWR thermal-hydraulics during shut down modes and reactor transients.
Broader Impact: The project will support at least two undergraduate students from underrepresented groups to come and work in the laboratory during each summer. This will give the students a chance to gain valuable hands on experience and stimulate their interest in the field of thermal science and engineering. Two Ph.D. students will also be supported as part of this project. The research accomplished will be presented at conferences and published in archival journals for general dissemination by the technical community.

I note that the following notice no longer appears. Apparently it was too convenient an access channel for those whom the NRC decided there should not be a straightforward disclosure.

We are currently having technical problems with the NRC's rulemaking website. All public documents are available electronically at the NRC's Electronic Reading Room at http://www.nrc.gov/reading-rm/adams.html. From this site, the public can gain entry into the NRC's Agencywide Document Access and Management System (ADAMS), which provides text and image files of NRC's public documents. If you do not have access to ADAMS or if you have problems accessing the documents located in ADAMS, contact the NRC Public Document Room (PDR) Reference staff at 1-800-397-4209, 301-415-4737 or by e-mail to email@example.com.Comments on rulemakings can be submitted via e-mail to firstname.lastname@example.org or via the Federal eRulemaking Portal at http://www.regulations.gov/.
Our contractor is taking every step to remedy the problem as quickly as possible. Thank you for your patience.

So, let's relax and enjoy ourselves as we forget about Regulation by Myth! Let's go into the world of precision skydiving at http://www.aerialfocus.com/ to view a fantastic video clip and other presentations.
The above photograph shows the Silver Surfer attacking the formation "4." Moments later, the formation is shattered as the Surfer penetrates the eye of the perfectly built 4.Of course, skydiving is for everyone, although it takes a bit of practice and devotion to match the skills of the Silver Surfer and the formation "4" The photographs below show blogger Leyse in action about 22 years ago.
This is a great scene as my jumpmasters flee. From that point on, I am on my own (mostly).
