A few miscellaneous items.

Rain Barrels
A few weeks ago I built this rain catching and redistribution system to make use of an otherwise wasted resource.  I managed to install a nice drip system on it and after the last couple of weeks I can gladly report that it works well.  And all in, it has cost me about $30 (not including the drip lines).

To my surprise, I saw that Home Depot also offers a rain barrel (even though they are technically illegal) with 57 gallon capacity, but a slightly more asthetic appearance.... for $98!  1/3 the capacity, 5 times the price! (I'm definitely sticking it to the man!)

Seeds are sprouting

The seeds are definitely starting to pop up!  Underneath the greenhouses at least.  If you haven't started already, it's time to get the garden into shape!

The cost of going solar

I've been working on helping my cousin get a Mission Center off the grid in Costa Rica where Electricity can be very expensive (more than 2 times as expensive at the top tier).

In our research I found a formula for determing the cost of PV solar panels to take your home off grid (in Colorado).

Cost of PV solar panels = Avg. Monthly Electric Bill *10,000 (watts-per-$) / 30 (days-per-month) /5.5 (sun-hours-per-day)*3 ($-per-watt)

For my little house here in the Boulder area I would need a 4.3 kW  system... costing about $12k (for the panels) + other needed accessories.  And I'd still have to purchase a large battery bank to make up for cloudy days.

Hmm... where am I going to get that kind of dough?

Geodesic Greenhouse. I want one!

Thursday, April 2nd, 2009

I found this really cool set of instructions for building a Geodesic greenhouse.  Anyone want to join me in making one?

Maybe you really just have to be a math nerd to long for a geodesic dome greenhouse :-)

Top 5 extremely cheap steps to living a more sustainable way

Friday, February 20th, 2009

My friend once asked me what the word sustainable meant in the context of society and humanity.  My reply was that it was:

"The ability for an organism or organization to perpetuate itself and it's progeny over time"

But how to accomplish such a large goal without breaking the bank?

Below are my top 5 cheapest and most effective goals towards becoming a more sustainable society and person.

  1. Composting - the number one cheapest solution to waste management, healthy food production and greenhouse gas reduction.  When food goes to a landfill it takes with it valuable nutrients.  Furthermore, as it decomposes in the oxygenless environment of a landfill it releases Methane, a greenhouse gas 25 times more 'greenhousey' than Co2.  And even if you don't have a garden, or friend with a garden, to put the compost in, you can always spread it around some trees at the park... I'm sure they'll appreciate it!
  2. Insulation - Insulating our houses and building will keep the hot air in (or out).  It's one of the simplest technologies around and when applied correctly is extremely cheap.
  3. Solar/geothermal heating and Cooling - Sunny climates can get most of their warmth through the winter from the sun, and dry climates can get most of their cooling needs from evaporative cooling in the summer.  If an extra step is taken, warm or cool water from the earth can be used to modify the temperature of a house or building as well.  Cooling and Heating our buildings is the #1 usage of energy in the world.
  4. Walking/Biking for transportation - it may not be suitable for commuting on snowy or blisteringly hot days, or for trips greater than 3 or 4 miles.  But that's okay because the vast majority of trips we make are < 2 miles and in places like CO there are over 300 sunny days a year.  Walking is free and enjoyable!  Biking is almost as cheap.
  5. Micro Farming - aka gardening.  Participting in growing your own food (if only even for a few tomatoes) is perhaps the most beneficial and cheap green activity.  It teaches you about: soil health; what it takes to grow food; what it takes to use water efficiently; how much work goes into getting a return on your investment; and finally it teaches you to be much more conservative with your food purchasing and consumption.  One quickly realizes how what goes into the soil, goes into the plant and ultimately into us! It also helps to really learn the old maxim: waste not want not.

Enjoy your cheap sustainable life!

Building solar projects on the cheap

Thursday, February 19th, 2009

For the last week or so I've been semi-obsessed with building and testing out my latest solar project: a solar powered space heater for my office.  You can check out my work which I documented here .

I've also recently built and tested (with success) a Tesla Turbine ... I'll probably make a page dedicated to it as well .

Finally, I'm working on YASP (yet another solar project).  This time I'm making use of my math and artificial intelligence skills.  I'm writing a piece of software which simulates a reflecting dish that (ideally) focuses sunlight on a central point.  Parabolas do this just fine, but the problem is that when the sun moves the parabola has to as well.  I'd like to find a dish shape that requires no moving through the day and still reflects a large portion of the solar rays (even as the sun travels across the sky) onto a central area.

So yep... things are humming along over here!

Kill-a-watt

Wednesday, February 4th, 2009

Greenies are known for being penny pinchers and energy misers.  But how to go about it in a scientific way?  And can you even really save that much money/energy consumption?

Recently I purchased a Kill-a-watt (~$20 on Amazon.com).  The kill-a-watt is a simple device that plugs into the wall.  To measure your energy usage, you simply plug in the appliance or a power strip with several appliances.  It has an LCD and several functions to help you monitor your device(s) energy usage... both when they are on and when they are off.

But when my coffee maker is off, it's off right?

No!

Surprisingly (to me at least) most modern appliances still consume a fair bit of electricity when turned off!  Commonly this phenomenon is known as "Vampire" electronics.

So how much money will I be saving by utilizing my kill-a-watt and a trusty ol' on/off power strip?

My work desk includes the following items:

  • speakers - 25 watts on
  • laptop - 20 watts on, 1 watt off
  • cable modem and wireless router - 25 watts on
  • Xbox - 90 watts on , 1 watts off
  • Monitor - 30 watts on, 1 watts off
  • Desk aggregate consumption during work hours (while not playing video games) - 100 watts
  • Desk aggregate (laptop, Xbox and monitor off) - 50 watts !

Summing up, I can see that for the 16 hours a day that I don't use my desk, it's still drawing 50 watts.  Over 1 year's time this consumes $33.28 of electricity.  Call me a penny pincher but by using a power strip for the whole system, and spending the 2 seconds per day to turn the strip on and off I can squeeze out just a little bit of savings (making the equivalent of $230/hour... just to flip a switch on and off).

I can't wait to find more ways to kill my watts!

Greentheo's plan for economic recovery

Monday, February 2nd, 2009

It all seems so overwhelming.  The economy is a sinking ship.  Everyone is losing their job so it seems.  We're all going to be poor!  And to top it off, Democrats and Republicans can only agree that Billions (800 of them) must be spent in order to save us.

We all know that borrowing more money (to solve a problem caused by borrowing too much money) wont work and neither will printing money.  Long term both solutions require higher taxes on our children and increased devaluation of our savings.  That is, if we are lucky enough to have savings!

But we're not helpless!  That's right!  You the average citizen can help save the country even while Senators and Presidents are busy trying to ruin us as quickly as possible.

  1. Refuse to let the news affect your well being.  Keep up your productivity, creativity and hard work.  Keep investing, saving for the future, learning and above all spending time doing things you love with people you love.  If you become part of a negative statistic, work hard to turn it into a positive one!
  2. Pay off your debts and refuse to live a high risk[1] lifestyle by purchasing from a surplus and not a deficit.  Being debt free not only gives you a 10-20% discount on everything you buy (no debt = no interest payment), but also lowers your interest rate on things you might consider going into debt for in the long term, like a house.
  3. When you buy, buy local.  Money spent in the local economy has a much higher chance of coming back to you.
  4. Repair, don't upgrade.  If you want to stimulate the economy, the best way to do so is through wages.  When a product, like repairs,  consists mostly of repairs it enters the economy (especially the local economy) much more quickly.   Repairs are not only labor intensive, but also save money for you in the long term.
  5. Donate to charities.  Giving frees you up from the focus on getting more.  If you aren't focused on more, you may start to be focused on actual productive activities.  And besides, charities are a great way to release money into the economy... they have no problem spending it on the services that stimulate an economy the most.
  6. Give your time to folks with special needs, mental health issues or just plain disabled people.  Mental health issues not only impact 1 person's life but 100's of other's who help care for them.  Special needs are a fact of the world.  Helping them out is to give them the ability to reallocate their resources elsewhere.
  7. Rake an old person's lawn, or help them fix their house.  It's extremely expensive to live in a retirement center and most older people can't afford it.  What if instead of giving all their money to a retirement home an older person could spend it elsewhere in the economy?
  8. Help prevent substance abuse.  Have a young friend who is soon to be hooked on drugs?  Hundreds of people are negatively impacted financially and emotionally by 1 substance abuser.  Not to mention that it's hard to be productive when you're wasted.  Do your part and help others to say no.
  9. Repair your marriage.  Divorce and relational hardship are a huge drag on an economy.  Not only does it cost money in legal fees, but it costs productivity, creativity, energy and emotional pain for years in both you, your ex-spouse and your children.
  10. Participate in friendships.  From carpooling, and networking to splitting vacation costs, free entertainment and above all... joy ... friendships are a must for economic stimulation.

Above all, keep in mind that economics is not about the exchange and getting of money, it's the exchange and getting of things that we desire and need.  Not all things can be purchased!  So let's get out there and stimulate our economy in whatever way we can!

  1. debt is extremely risky because of the default effect.  When just a few payments are missed the interest rates default to the maximum allowable rate drastically increasing the risk of bankruptcy []

Why Money Must Die

Tuesday, November 18th, 2008

Part of the Green movement's underlying philosophy is that cultural and societal structures need to be constructed such that they are sustainable.  One of the key components of sustainability is the ability for all parts of the whole to pass through a cycle of life and death.  One is born, grows, reaches maximum productivity and usefulness and then eventually dies, decomposes and is returned back into the system for future use.

This is the way of nature.  When something dies it is decomposed and with it's nutrients broken down and released back into the roots of the living it will be synthesized into something more useful, complex and beautiful.

Just imagine a world in which fungus, and bacteria didn't break down the dead and waste of the living...

There is one component of our society (of many) that not only does not die, it grows without bound: money.  It is perhaps the greatest barrier to a sustainable and otherwise green economy.

A proper, sustainable view of money needs to be embraced in the Green Movement as it will provide the economic base for the movement's ultimate goals.

Money is not the paper that we hold in our wallets, nor is it the gold that backs it in the treasury.  Money is the common faith medium of exchange.  And as a medium of exchange it needs to flow around like blood in the body.  It should be born when a product is created and sold to a customer and then put to death when the producer turns consumer and spends his wage.  When money is spent it comes back to life.  It is this cycle, the death and rebirth of money from consumer to producer, producer cum consumer to the next producer etc. that keeps a society flowing and functioning.  It is the opposite, when money is stuck in the bank, or the sock drawer that a society becomes depressed and ill-functioning.

So what happens when the money fails to die?  If money sits in the bank collecting interest it can only be growing and growing, like a virus or a cancer.  Soon it becomes so large that the owner couldn't even spend it all in a lifetime if he tried.  And like garbage in a landfill it serves no purpose... unable to die and return to life through the roots of the living consumers and producers.  The living consumers and producers starve while the money is locked away in some remote reserve...full of life... but locked and hidden away.

There are several means to accomplish the death of money, the easiest one is to schedule it's devaluation in order to make it unattractive as a means of hoarding wealth.  When we eliminate the immortality of money, then we eliminate it's future purchasing power, creating a level playing field for all.  If the playing field were level I believe that the best, most efficient and productive technologies would be the most sought after and thus the world would necessarily become Greener and more sustainable.

If we want a sustainable world, one where our children don't have to face the imminent dangers of a toxic ecology, or food shortages or natural disaster then we have to try to make every part of our world sustainable, including the money system.

Fuel Grade diesel produced by fungus

Friday, November 7th, 2008

From gaurdian.co.uk.

Fungi and microbes are some of the most important organisms to our planets health.  Without them we would not have rich and fertile soil, we would also suffocate under our own excrement and waste.

Recently, I posted a video on how fungus may save the world through the recently discovered ability of mushrooms to defend against viruses and for their role in producing biofuels.  Fungus has even become recognized as so important that Department of Defense grants have been given out for the purchase of old growth forests in order to protect certain rare and unknown strains.

And now comes this announcement, a strain of fungus from Patagonia has been identified that takes cellulose and sugars and produces fuel grade diesel.  Amazing!

But if that isn't enough, the researcher who discovered this fungus also says the following.

Strobel also said that his discovery raises questions about how fossil fuels were made in the first place. "The accepted theory is that crude oil, which is used to make diesel, is formed from the remains of dead plants and animals that have been exposed to heat and pressure for millions of years. [But] if fungi like this are producing mycodiesel all over the rainforest, they may have contributed to the formation of fossil fuels.

As a young earth creationist and a scientist I've always wondered how to work out the oil problem, which is that crude oil supposedly takes millions of years to be created.  Now with the discovery of such things as mycodiesel, algae wich hold up to 50% of their body weight in oil, and the possibility that prior to modern deforstation and the like their could have been any number of oil/diesel producing fungi/organisms responsible for the oil deposits we find.

The cheapest and easiest to install (non) skylight ever

Friday, October 31st, 2008

Why should you spend $400-$1000 on a skylight and ruin your perfectly good ceiling when you can have one of these.

The problem with most windows is not that they don't let light in... it's that the light falls on the floor instead of filling the room.  The problem with a skylight (as lovely as they are) is that they cost $400-$1000 and will take up more than one weekend with the necessary destruction of some portion of your ceiling.

Solution: add a mirror (or two) to the window sill and angle it into the room.

The mirrors cost about $7 at your local hardware store and when angled properly will redirect sunlight off your face or desk, and onto the ceiling where it provides free natural light for the whole room.

Why pay for electricity and expensive "natural" light bulbs when you can have actual real sunlight?

Choosing green can be expensive... especially because it's usually free

Wednesday, October 29th, 2008

If you haven't heard by now, vitamin D is being touted as a major preventative treatment for all types of cancer and health issues.  If you've read any number of books set in the 19th century where some wealthy person takes ill, you'll recall that the patient is usually taken out to the countryside to get some fresh air and sunshine.  Turns out it was a pretty good idea.

How much does this miracle cure cost?  It might seem obvious that clean air and sunshine should be free, but...

For the average American male, a good daily dose of sunlight would require 10-20 minutes with 40% of their skin exposed to some prime sunlight (somewhere between 9am-4pm).  Achieving this requirement might mean that he goes shirtless outside for 15 on the front side and 15 on the backside... a total of 30 minutes.

But this is a problem.  The average American Male works over 40 hours a week, and last I checked most employers discourage topless sun bathing on the job.

Supposing the average American male decided he would take 1 hour less pay, 3 days a week[1] and blend in a nice run through the park[2]  with his sunbathing for ultimate health.  30 minutes to stave off heart attacks and cancer, not too bad.  Add in some clean up time and the hour is up... back to work.

But with 3 hours less pay a week, the average American would take a salary cut of  nearly $2,500.((http://en.wikipedia.org/wiki/Average_Joe)).

$2,500 for free sunlight and jogging?  Who could afford that? Especially with an average salary of about $32,000/year.

That's why I've decided that although America is the wealthiest <strong>country</strong> in the world, it's citizens are some of the poorest... we can't even afford to enjoy free sunlight and a free jog in the park.

  1. If you can find a boss willing to let their employers do this, just let me know []
  2. running outside also astonishingly still free []
