Retroinformation ideas

Here are some ideas that I've been throwing around over the years. Vernor Vinge and I used to talk about these things at our lunches the Greek restaurant in Sorrento Valley.  Retroinformation: Information that can be communicated between different eras and scales.  Wormhole Transport Protocol (WTP) an information transport layer that extends HTTP to allow endpoint servers to be in different eras or scale. HTTP with parameters for era and time domain. Information is filtered via a CASER mechanism, which blocks information that is not self-consistent.  Channels may open up between scales, such as quantum and macro scales, or ants and their ant colony, or worms and their ecosystem. Wormhole Transport Markup Language (WTML).  A language used to describe the communication channel to communicate between endpoints using the WTP servers.  This language protocol will start out simply, and evolve as the level of trust and consistency increases. Era: a time domain, describing the time domain

Underwriter''s lab approval of DIY Box Fans

UL has reviewed the Corso Box fans and found them to be safe from overheating. The fan I bought at Home depot also had a thermal protection switch Underwriter's Lab approval of DIY Box Fans "Across all fan/filter test scenarios, the most notable temperature increases were observed at the motor and motor windings. However, all measured temperatures fell below the maximum acceptable thresholds defined by the market safety standard for electric fans (UL 507). Exterior surfaces that can come into direct contact with people remained below 36 °C, which is below the first-degree burn potential of 47.5 °C. Further, an extreme scenario where both the front and back of the fan were blocked for an extended period of 7 hours did not pose any observable fire hazards. And after an initial rise, temperature remained steady throughout the test."
