Commercial Property Insurance

I have told my colleagues at work and my close friends that insurance was the last thing I expected to keep me from realizing my dream.

State Farm issued a business policy at a reasonable rate but then retracted it almost immediately because of miscommunication between the agent and the underwriter about what they were insuring.

I eventually switched to Farmers because they offer a “Business Pursuits on Premises” endorsement – an inexpensive line item but a more expensive policy overall.  But that complicated finances between my personal account and the LLC and there were some who questioned if Farmers would pay on a loss (did they really know what they were insuring?).

Finally I found an agent that knows his stuff at Walnut Risk Management here in Kansas City.  He understands what my concerns (risks) are and the value of the asset (not just BOM but labor too).  We got the binding confirmation today for the property coverage.  He also has a general liability policy lined up for when we are ready to take riders.

Needless to say I will sleep easier tonight.  And I have the flexibility now to reposition the simulator for my employer’s BBQ next month and Maker’s Fair (if they ever respond) in June.

Cooling Woes

As I am going through building the virtualized ship systems I have seen waste heat expulsion rear it’s ugly head a few times.  Since we are primarily operating in the atmosphere for the foreseeable future I am going to document my findings here, solicit feedback, and move on.

I plan to have three coolant loops (two primary, one standby) each with their own pump and reservoir.  Each device in unpressurized sections of the craft will have a heat exchanger (oil to coolant) or a heat sink.  Anhydrous ammonia was suggested for it’s vaporization properties in the temperature realm I am needing.

The idea is then to take fuel and/or oxidizer out of cryogenic storage using the excess heat carried by the coolant.

Since the fuel cell creates water as a byproduct, we could also dump hot water overboard.

Superficial heat exchangers (coolant to air) could be mounted inside the exterior plating but that leaves the system vulnerable (military operation, after all) and it only works in the atmosphere.

I heard that the space shuttle radiates heat from a shiny surface on the inside of the payload bay doors?  I thought that materials which absorb heat best (matte black) were also the best radiators (why some engine manufacturers powder coat their engine blocks).

I have also been researching the holy grail of waste heat management – thermopiles.
