The Amazing Mr Parrott April 17, 2010

When Ish first told me about his friend, i was skeptical. He described a simple electrolysis device which Charles Parrott had developed and added to his car which dramatically increased his gas millage. i studied enuf classical economics to believe that any inexpensive millage enhancing device would be embraced by Detroit as a way to stave off the need to retool assembly lines due to federally mandated millage requirements.

When i talked with Charles, my perceptions began to shift. An unassuming man, he was clearly an inspired tinkerer and capable inventor. When i asked him why he did not take his hydrogen generator into business he said “Business would be boring.” It was also clear that he appeared to be more interested in new projects, growing algae for energy and zip lines and tree houses (which is why he was interested in meeting me).

He gave me an early version of his hydrogen generator, which is pictured below. The theory is simple enuf, the device breaks down water using electricity the car produces while driving but can not store because the battery is full (this device likely would not work as well on hybrids which are more clever about energy use and conservation). Water becomes hydrogen and oxygen gas which is then feed into the carburetor where it burns hotter and more efficiently than the nitrogen rich air which generally inhabits that space.

i called my old engineering friend Rez to ask him about the physics of the proposition. Rez pointed out that electrolysis is not an especially efficient operation but that neither is internal combustion, despite decades of refinement. That the equation for the increased energy was

Enew = (Egas + EH2 – Eelectrolysis) * Fnew

Enew = Energy with combined gasoline and H2 fuels with enriched O2 (oxygen is the oxidizer)
Egas = Energy running just on gasoline
EH2 = Energy from burning the hydrogen
Eelectrolysis = Energy to run the electrolysis (this is not free, when the battery is full the alternator doesn’t have to work)
Fnew = Efficiency factor for the engine running gasoline/hydrogen/oxygen-enriched fuel.

Average gasoline engines are ~20% efficient, wasting 80% of the energy in the gasoline. The real gain will be in Fnew jumping due to improve flame propagation speeding the combustion and making it more complete.

Rez took some exception to my calling the surplus energy from the over charged car battery being called “waste energy” and in the end concluded that the only way that the physics would work would be for the burning of these gases to increase the actual efficiency of the car engine, which he held was possible and a bit tricky to measure. Rez also scanned the internet, found many studies in the SAE (Society of Automotive Engineers) publications finding that efficiency improvements of 12% (a study at MIT) and vastly reduced emissions [ see abstracts at half way down the page]. Interesting design of a electrolysis unit that uses the waste exhaust heat (which does nothing else useful) to make the H2 and O2.

Were  i not obsessed with this festival i might dive into this device and do some testing.  Charles says he drove it from Springfield MO to San Diego and got 60 mpg while an identical vehicle (owned by a friend) got 48 mpg – both Geo Metros.

Building and breaking and emboldening April 12, 2010

Filed under: Uncategorized — villagesinthesky @ 2:08 pm

(Sara) It isn’t easy, this game of culture creation.  In fact this post comes late and is being written in Virginia, because I was told I was going on vacation and nearly forced into the car.  The stresses of the project have been overwhelming and nearly too demanding, but give me a good book, a couple of days hiding out and I will recover.

Seed camp has started and is motivating me forward and westward.  What we’re building at seed camp is more than pole barns and dirt ovens, we’re building a family, a foundation for the festival.  The people we’re working with are brilliant, bold and deeply compassionate.  Fifteen people moved onto a piece of land in the middle of the foothills with no electricity and no running water.  Some of the first things we had to address were practical: waste management, food storage.  So our friends at East Wind built us a composting toilet for the site and trained us in human waste management.  Shiloh, who came out to cook, had read about earth boxes on the internet and started digging an angled box into the ground, lined it with large rocks from around the site for insulation, and packed it all in for refrigeration.  Jason built the camp some furniture out of salvaged slab wood and brush piles for burning.  And more projects carry on as I hide away in Virginia: a dirt oven for baking bread and such, a sweat lodge, solar showers.  This is exactly what we want to be inspiring people towards with the festival: inventive, creative and simplistic solutions to living in this world more cooperatively, more symbiotically.

But the physical infrastructure doesn’t even touch the depth of the emotional and human infrastructure we’re building.  It’s hard to avoid each other in our small space with limited creature comforts.  At night we gravitate towards the campfire, because it is the most compelling source of light (the only other being one propane powered lantern).  During the day we work and play with each other.  And already we’ve tested the capacity of our small village to hold each other and support each other and challenge each other to grow.  It came right as we were about to drive the 1,000 miles back east.  We were thrown by the request and almost unanimous support of camp to take one of our volunteers back with us, unexpectedly.  It was true, he was tricky–easily distracted, not working as much as he could be, socially awkward and just beginning to grow up.  There was a series of conversations about it: checking in with different camp members, getting the advice of those who are and would be living with him, speaking with him personally.  And when he heard the decision of the camp, he was shaken, it wasn’t an easy decision, and he wanted one chance to speak with everyone himself before riding back with us.

I sped away along the soggy and potholed roads to negotiate our parking lease with the next door neighbors and talk about trucks.  While I was gone something unexpected and profoundly inspiring happened.  The unwanted camp member spoke with the others at camp and everyone met without him to make their decision together, without the interference of some pesky “lead organizers.”  The unanimous decision:   let him stay, we will help him grow, keep him on task and pick up slack where he is sure to drop it from time to time.

With the good news, I got back in the car, my heart breaking.  I knew I needed to leave, or I would be nearly useless to the project, but I was leaving behind something so thrilling.  We had gone through hell together, with tensions building between the project and our host community.  But they’d broken just the day before and we were stronger for it, more determined.  If nothing else comes of this wild project and this last year of my life, I will owe it the experience and learned wisdom of building community, being taught by others the strength of cooperation and the true meaning of “it takes a village.”

The ommission from this story is that I was so exhausted and spread thin that last day, that I didn’t care what happened with this camp member.  I would have made the more callous and less challenging decision.  And I’m humbled to be part of a group, of a family, that will remind me what the right decisions are when we’re creating our own culture.  It was a challenge to my own growth and I don’t think they know it yet.  It will have to wait until I get back to camp.  I can’t wait.


April Fools Party and Progress April 4, 2010

Filed under: build up camp,Project Personalities,Salvage — villagesinthesky @ 4:56 pm
(Sara and Paxus) It is late after a long day and we are preparing to go to sleep in the back of the Subaru on the couch cushions which Deborah brought up.  She also brought up a dozen cheery East Winders for a sing along and some beers after a beautiful warm day.  We had said we wanted to have a party after our first full day of seed camp and then we kind of forgot about it.  One of the nice things about having a community as a neighbor is that you can whip up a party pretty quickly.
Today is April Fools and an appropriate start date for such an unlikely project.  And over the post couple of days a lot has come together.
  • we have nearly finished the demo of the yellow house and salvage of siding and 2 by boards (lots of de-nailing).
  • Teo built us the cutest little comptoil outhouse from a giant peanut sack
  • Jason and Shiloh banged out some nice benches (photos to come)
  • Sara and Shiloh and others completed the root cellar
  • zeke brought in some shelving for the kitchen
  • Ish and Matthew put a bunch of rocks in the potholes, which desperately needed attention.
Pilgrim and Paxus discussed volunteers and how to keep them happy.  Pilgrim wanted them to be on the site during the daylight hours and taking off to the river or other events after the day was over.  Paxus took a more summer camp perspective, thinking that volunteers needed to be happy and able to run off to adventures during the day some days.
We will fight and we will discuss and we will make sure that we’re creating an experience that is the best parts of work on a short timeline and play on a big scale.  That’s what we’re all about.  And we’ll take care of each other.  It’s a culture more than a festival, that we’re creating, and if we can’t go swimming at the end of the day, in the middle of the day, at the beginning of the day, then what’s the point?
