Rejection! Burning Man DMV Rejects Most Useless II

Sadly, the Burning Man DMV department has decided that Most Useless II doesn’t meet their minimums. Here’s the rejection letter:

Mutant Vehicle: Most Useless, II
Registration #: M20-0254
Owner: Peter Kropf

Dear Peter Kropf,

The DMV has carefully reviewed your application for your Mutant Vehicle project Most
Useless,II (M20-0254) and we’re very sorry to inform you that your vehicle was not 
accepted for invitation to Burning Man this year.

Please read this letter carefully for more information about the decision regarding 
your vehicle.

The DMV Review Team felt that:



Unfortunately, your vehicle as presented in your application does not meet the 
minimum criteria for a mutant vehicle license:

"Level of Mutation / Visual Presentation

Mutate your vehicle to the point that it is not recognizable as a street or stock 
vehicle. A radically mutated vehicle will not resemble or represent a car, truck, golf
cart or any other readily identifiable street or stock vehicle. In most cases, little or
none of the base vehicle should be visible. Beyond just changing, covering or hiding
the base vehicle, the mutation should aim to be visually compelling, providing
“wow factor” for the other participants of Black Rock City. When a person sees this
vehicle, their reaction should be “Wow! Look at that!” If a vehicle maintains it’s 
stock form (i.e. – it keeps the shape of a bus, golf cart or street vehicle) it may not
be sufficiently mutated to meet the Mutant Vehicle Criteria."
* * * *

The DMV Review team felt that while your vehicle has custom attributes, and we
appreciate teh "Most Useless" concept, overall the design does not fundamentally
change the vehicle's visuals from the base Taylor-Dunn.

We should be clear that the team overall enjoyed your vehicle, but in the interest
of fairness, we could not invite as the base is too much the same as the stock 
vehicle it is based upon.


Due to the high number of applications and the limited number of vehicles we can
invite, we simply can't invite all applicants, even when they meet the minimum 
requirements.  We don't want anyone to have the sad experience of bringing a
vehicle out to the playa and having it denied a license after all that work!  We
do our best to give invitations to those most likely to get approved on playa.

We very much understand that you have committed significant time and resources
to creating your mutant vehicle (many of us are mutant vehicle creators ourselves,
so we know what it takes) and that this is hard news to receive.  The level of 
execution of mutant vehicles submitted by the Burning Man community for review
increases from year to year, and unfortunately, there is a limit to how many 
moving vehicles we can allow during the event. Your vehicle simply did not exceed
the very high bar that has been set by your fellow Mutant Vehicle creators this year.

Once again, we realize that this is not the news you likely wanted to hear, but we
do want to thank you for the effort you made and look forward to seeing you on the

LPG Cylinder Sizes

On a regular basis, I’m building flame effects that are fueled with propane. Invariably for the larger effects, I’m scrambling around looking for specifications and details on propane cylinders to just how long an effect will run given a certain amount of fuel, or how long before this effect freezed the cylinder, or what are the basic dimensions to know how to build the mounting mechanism(s) for the cylinders. So here’s the first table showing basic dimensions and weights associated with propane cylinders. For the curious, the 20# cylinder is what you would typically next to a BBQ.
