Free Market or big racket economy?

Monday, November 16th, 2009

I hate to complain on a blog but...

It is commonly held that in America we operate under a mostly free economy.  Free meaning the consumer can choose which good to buy based on her criterion and the producer is free to produce what she likes.  Our economy is held to be "mostly" free because we the people also hold certain products to be more important than others, so we subsidize them to achieve greater economies of scale ensuring that those goods will always be found in ready supply

I posit however that America does not have such a free economy.  I posit 3 points as evidence.

  1. Recently it slipped my mind that I had a credit card bill due.  We don't use it very often so it wasn't on my priority list.  And since this credit card had no "auto pay" feature I was late by 3 days. Thus I triggered an automatic "rate increase" from my previous 3.25% APR to the kindly rate of 29.65% !  What?! Seriously?!  My 5 year loyal customership meant nothing?  My only option was to pay the ridiculous interest rate or cancel the card.  Cancel I did.  If it was a free economy then the amount of pressure to keep me as a customer would be great enough that Capital One could not survive as a business without offering me more than the given two options of pay up or get out.  Instead they would be forced to assess a one time "late-fee" and only when my credit score changes could they move my interest rates upwards.
  2. The cellular phone industry is another good example of why our markets are not free.  The cellular phone industry has figured out how to 1.) lock people in to their service by assigning them huge penalties for leaving prior to the end of 2 year contracts 2.) sell "plans" which either provide excessive usage capacity (1400 minutes) or under capacity plans (700).  If you happen to have the misfortune of exceeding your minute usage then the cost per minute of usage goes up by a factor of 10 to 20.  Under a free market, prices must remain fairly liquid and transparent.  A free market economy would provide the ability for 1.) free transferance between services and 2.) more liquid pricing (i.e. 700, 800, 900, 1000.... etc.) minute plans.
  3. But perhaps the biggest example is that producers are not free to produce what they like and what they are best at.  How many producers and workers are employed at something they are both good at and enjoy?  How many workers have the freedom to take the day off to go look for another job?  How many folks have the freedom to change jobs and not worry about their health care benefits while they change jobs?  How many folks could balk at unreasonably low pay or poor working conditions in a serious enough way to affect a significant change in their working condition?  How many companies are producing top quality goods to meet an unmet demand...how many are producing goods simply to survive?

This is why I beleive that 1.) Credit card regulation 2.) Public option health care will provide a freer and more robust economy.  When the average consumer has choices then everybody prospers.

Even Texas is catching on...

a house made from recycled wood

a house made from recycled wood

My cousin who I built the Costa Rica Especial v2.2 windmills with in Costa Rica lives down in Texas (though he would note that he's only a recent transplant) and I grew up in the Houston area.  For a while I thought we might be 2 out of the 7 Texans who cared about the environment...

But wait!  There's more!  I'm so incredibly jealous of this man's business, building houses from recycled building materials.

So far, he has built 14 homes in Huntsville, which is his hometown, on lots either purchased or received as a donation. A self-taught carpenter, electrician and plumber, Mr. Phillips said 80 percent of the materials are salvaged from other construction projects, hauled out of trash heaps or just picked up from the side of the road. “You can’t defy the laws of physics or building codes,” he said, “but beyond that, the possibilities are endless.”

It may not mean all that much to you my loyal readers, however I lived about 20 minutes from Hunstville (the death penalty and execution capital of America) and let me personally say, environmentalism is very nearly a four letter word around there.

Congratulations Texans!  Welcome to the rest of the United States of  America!

Humanure

Wednesday, September 2nd, 2009

Lo-LandfillI just finished the online guide to Human waste composting.  I have to say that it's been one of the most interesting books I've read this year.

Folks... we're literally going to be drowning in our own poop if nothing is done to recycle the billions of pounds of poop we produce and bury in landfills (Does anyone else see how silly this is?  Can we really not figure out anything better than burying our own poop?).

Anyways, I thought I'd put a link up to the condensed version of the book: http://www.jenkinspublishing.com/downloads/humanure_instruction_manual.pdf.

CR Especial v2.2 videos

Monday, August 24th, 2009

I finally got 2 of the videos of my cousin's and my work on the Vertical Axis Wind Turbine (VAWT) in Costa Rica up.

Some extended information: Each of these turbines is 6 feet tall... the total width of the two turbines is 10' ... it's pretty big and will definitely crank out the wattage!  We estimate that the payback period for these simple to build[1] turbines will be 2-3 years.

Each of these was built for about $250 excluding the generator, electronics and batteries.  We think and hope that they will last for at least the next 10-20 years with very little maintenance.  They are solid steel construction turning in automotive axle supporting ball bearings.

Greenest Transportation

Monday, July 6th, 2009

I've recently changed my thoughts on the greenest form of transportation.   The best and most economical transportation in the future will be Natural Gas or biodiesel powered busses, complimented by electric grid powered trains (or just biodiesel-electric) and natural gas powered vehicles.

The advantages of using Natural Gas and biodiesel is that any existing gasoline powered vehicle can be converted to run on Natural Gas and any existing diesel vehicle can be run on biodiesel.   Natural Gas burns cleaner than gasoline too.  A further bonus is that no highly toxic battery packs will be needed.

More importantly though, Natural Gas can be manufactured in anyone's backyard or can be piped directly to our house.  Most neighborhoods in the US have natural gas infrastructure.   Bioreactors utilize common strains of bacteria to take biomaterial including fecal waste and turn it into compost and fuel under anaerobic conditions.  Biodiesel is made simply from vegetable oil.  A Natural Gas and biodiesel based economy will be more efficient, less polluting and less dependent on foreign oil.

Mass transportation like buses and trains will continue to help green transportation but only as cities develop in more controlled and planned ways.

My prediction... if oil climbs like it did in 2008 and keeps going up we will see the emergence of not electric or hydrogen cars, but natrual gas conversion kits and more diesel based vehicles.  It's simply cheaper and more robust.

CR especial V2.1 update

Tuesday, May 5th, 2009

Version 2.1 of the CR especial turbine has been completed and attached the base mounting structure.  .

Here is a nice shot of the turbine down in Waco, TX.

cr_especial_v21.jpeg

And a video.

[youtube]http://www.youtube.com/watch?v=5BZBJ2lzE5U[/youtube]

Dimensions:

  • 24" diameter X 60" blade height
  • 4" wide blades constructed from 4" drainage PVC cut into thirds.

Other stats:

  • All PVC for the blades, shaft and connections.
  •  Current mounting height.. about 10'
  • Total cost excluding generating engine - ~$50

A nice feature that Bryan added was putting a coupling in the middle of the shaft so that the blades could be phased into the wind spreading the torque of the blades throughout the rotation.

Performance and future work:

  • Wind down in Waco isn't especially strong and consistent... but even so at 10' and with really small blades, the windmill does turn.  Next steps:  Elevate to 30', build replica in CO and take to top of Front range for testing.
  •  The blades used are 4" wide, and have little aerodynamic lift.  The windmill often gets stuck facing into the wind in slow wind speeds. Next steps: Craft light wings which create lift and are closer to12" long.
  • The diameter of the turbine is 24", this provides the ability for higher RPM's but lowers the turning torque.  Next steps: widen out to 48" diameter and retest.
  • The height of the turbine is an overall 60", not bad, but the 4" PVC for the shaft can go to at least 2 times longer without causing flexing issues.  Next steps: increase height to 96"-120"

We don't have any readings on the wind speed and power efficiency... mostly because we don't have the equipment.

But... if you're reading this, like the project, and have 300 dollars to donate to a tax deductible ministry please shoot me an email at munkey906 at gmail.com... we'll get some good data recorded and analyzed asap!

Updates on the Solar Heater

Monday, March 9th, 2009

The Solar heater has been running for about 1 month now and I have a few updates to make on it's performance:

space_heater_main_sc.jpg

  •  Maximum observed temperature in room ... ~74 degrees
  • Out of the last 30 days in my office I've only had the heater on 2 times.
  • It's been a bit warmer and sunnier than usual (2 F greater average temp in Feb in 2009 than 2008)
  • Estimated energy savings on electric heating bill in February, March (and by inference Oct and November) ~50-75% of total bill.
  • Number of hours of heat delivered per day ~8
  • Time when maximal temperature is reached ~3 pm
  • Time when temperature in room drops below 65 F after a full day of heating- ~10 pm-1am.
  • Maximum temperature inside heater ~110-130 F (even when it's 30 F outside)
  • Possible efficiency improvements:
    • glass on front of box instead of polycarbonate, with better sealing to minimize convective heat loss and maximize solar gain.
    • air must be collected from bottom of room for optimal heat exchangement
    • neighbor's tree and house must be removed for more direct sunlight.

But overall I'm quite happy with the project.  It has practically already paid for itself and best of all... my wife thinks that it's an acceptabley asthetic project completed on a nice timeline to warrant further tinkering in the garage :-)

Widgets for humans

Monday, January 26th, 2009

Ubuntu Linux is perhaps the most popular version of the Linux Operating system.  It's free of charge, runs fast and mostly without a hitch.  It's secure, comes with a friendly support staff (which is 99% volunteer, and quite helpful) and has an amazing variety of programs  available for download straight from a main menu ... also free of charge.

Perhaps it is Ubuntu Linux's motto which is the best reflection of it's quality:  Ubuntu, Linux for Humans.

The motto says 2 very powerful things:

1.) Silently, it says that all other versions of Linux aren't for humans, they're for programmers and geeks (who are either ultra-humans or sub-humans depending on your perspective).  Also by making the operating system free and open-source, Ubuntu is silently saying that other operating systems are either for utter domination like Microsoft or for the elite and snobby like Apple.  Therefore the motto summarizes that humans are those who want a cheap, well supported, superior (but not snotty), customizeable, and, above all, usable operating system for their computer.

2.) The motto also says that Ubuntu's primary reason for existance is to be used by actual people (i.e. Homo Sapiens) at whatever task they are performing.  This means that it is not meant for business alone, graphic artists alone, engineers alone, scientists alone, machines alone, servers alone, or anything in singular mode.  Rather it a universal human tool.  Human's are complex, at least 50% irrational, and variegated creatures... therefore a product designed for humans has to be ultra-flexible and powerful.  Ubuntu claims to be that in the motto.

Even the word human as opposed to people, person, man, woman, worker, business, internet or etc. seems to be chosen to connote the organic, earthy and complex qualities of humankind.

This short but powerful statement forces one to ask of their own products, widgets and businesses ... is it designed for humans?  Humans buy products, humans innovate and humans run the economy.  Machines don't invent themselves and businesses don't run themselves.  Business men are still men.  Even doctors, lawyers and academics are people too (well maybe not lawyers).

People are the foundation of humanity (how often do we forget that?).

So we must ask often... is my widget, product or business designed for humans?

Bailout + electric cars + power grid = free fuel

Monday, December 22nd, 2008

It looks like the auto industry will get the bailout that they've been looking for in the amount of about $18 Billion.

I didn't write the bill but if I had I would have made following changes.  Once implimented we could literally be seeing nearly free transportation (once the electric car has been paid for).

  1.  Condition the bailout on the introduction of at least 5 electric vehicles by GM and Chrysler.  The vehicles would be lead-acid battery powered, have a minimum range of 50 miles and a minimum top speed of 65 mph.   When better/cheaper electrical storage than lead-acid becomes available we'll all switch to it.  With a huge market available many more companies would jump on the battery development bandwagon... batteries are the single sticking point in electrical car design.
  2. While we're up to bailing people out why not just add in a few more dollars and improve the nations electrical grid such that they are smarter and have the capability to withdraw power from electric cars.
  3. Use the electric cars as a giant battery.  Wind power is cheap and way more abundant at night.  Furthermore, running a coal plant at the same power output 24/7 produces greater efficiency than trying to adjust the output to varying and somewhat unpredictable demand.
  4. Currently night time electricity is cheaper than day time and peak electricity so....
  5. The electric car owner charges at night with cheap energy, drives to work using a small fraction of the battery and plugs into a station at work hooked to the grid.  When energy demand peaks occur during the day, the power company pays to take some electricity from the car batteries to meet the demand.  Then a bit later it replaces the used electrity.
  6. As a bonus, replacing the roof of your car with a flexible PV would further reduce overall energy cost for the electric car.

No solid figures for the reader, but since electricity is cheaper as a fuel for an automobile and the difference between peak and night time energy is about the same price as the cheap energy one could likely offset all of the fuel costs.

Wouldn't that be a boon to the economy?  Imagine if instead of paying $1k-2k a year for fuel each citizen had no fuel costs.  If President Bush's tax rebates were an economic stimulus then having no fuel costs would have a double or triple net effect.

Working from Home

Wednesday, December 10th, 2008

Having worked at home for the last 8 months or so I thought I'd give my top 10 reasons to work at home.

  • The daily commute is about as good as it gets.  From my bed to the kitchen (for coffee) to the office my total commute is about 50 steps.
  •  Really great coworkers.  My two dogs Tommy and Nelly are always there for moral support. Few coworkers will ever be as cheerful and carefree as two young black labs.
  •  I can wear fuzzy slippers and no one will give me a speech (or dirty look) about unprofessionalism.  For the record I have regular and not fuzzy slippers.
  •  Productivity.  It really has increased.  Without having to check on hundreds of emails, or attend hours of phone or in person meetings my productivity has drastically increased. It's possible to increase productivity at the office by taking control of your schedule and placing limits on email checking ... but it wont be easy...
  • The view.  I used to work in a semi-dungeon.  It would have been decades before I got a window.  Now I get plenty of sunshine throughout the day, and a tax break that goes along with the fact that it's in my spare bedroom.
  • No politicking.  Being judged strictly on results is rare and refreshing.  Tommy and Nelly only know how to politic to see who gets to be pet first ... also a plus.
  • Lunch with my wife.  I get to eat lunch with her just about everyday now for about 30 minutes.  I also don't have to go out for lunch or pack a lunch anymore.  It's surprising how much time/productivity/cost this saves/increases/decreases.
  • Ability to multitask with thinking and small chores at the same time.   A surprising amount of key insights in my work lately have been achieved while doing the dishes, plucking weeds or going to Vitamin Cottage.
  • Living locally, Living Green.  I can now walk almost everywhere that I need to go on a daily basis.  Freedom is not just the ability to "roam about the country", but also the ability to stay exactly where you are.
  • Freedom.  As long as the bills are paid (i.e. the obligations of the contracts you work on) you really are free to work on the jobs you want to work on, the way you want to work on them, with the schedule that you desire (as long as it doesn't negate the contract).  You are also free to choose your own insurance, your own vacation time (subject to paying your bills of course), your own equipment and most of your coworkers.  What's better than working at home?  Working in that foreign country you've always wanted to live in but never had the cash or courage to do so.  What's better than quitting your job?  Quitting a small portion of your job and finding another contract to replace it without suffering a monumental shortfall in income (make sure you have an escape clause in your contract!).

As an addendum to my list I would also like to point out that the number 1 reason most people do not work from home, or for themselves (as a contractor, consultant or entrepreneur) is fear: fear of failure and fear of the risk of unemployment or varied employment.

However, in the last 8 months since leaving Google two conclusions have been solidified for me:

  1. Mathematically you are far less likely to suffer a catastrophic loss with a diversified portfolio of income.  For example, working 4 contracts is far less likely to result in the loss of all 4 contracts at one time than working 1 full time job is to result in being laid off.  Self-employed diversified income is usually more variable, but long term it is far more dependable.
  2. In the United States all employment is 'at will', mostly meaning at the will of the employer.  You may leave your job any time you wish, but more importantly your employer may ask you to leave at any time.  When it suits the company they will have absolutely no loyalty to you no matter what you've done or how much time you've put in.

Here's to freedom for the working class!
