Intake Cleaning

It's been a while since my last post, here we go.

Took my 2001 Jetta TDI over to a fellow Veggie Jetta TDI driver to have the intake manifold and exhaust gas recirculation control valve cleaned after another 100,000km. I did this before, so here are some of today's photos.

A (clean) TDI Manifold:


What came out of mine using scrapers and steel brushes:


Upclose, the stuff is so black, the previous photo couldn't Auto White Balance to pick up the detail:


Even after that mess and some time in the solvent station, we could feel with our nitrile covered fingers there was some build up left. So we took a propane torch and some compressed air and ...



Yup, that did it.

Performance of the car is now a lot better, and I'm sure better efficiency. I'll update the fuel effciancy graphs in the top-left of this blog after our next refill (2-3 weeks from now).

Cap-and-Trade vs. Carbon Tax

Question: What's the big deal with the fight between Carbon-Tax and Cap-and-Trade?

Answer: Perception, enforcement and finance.

Perception

Let's assume that two proposed policies are looking to collect $1B from the economy - Cap-and-Trade and Carbon-Tax. First off, it's easier to sell the free market aspect of a Cap-and-Trade over the tax aspect of a Carbon-Tax.
It's a matter of perception.

Convincing voters to pay "yet another tax" will hurt your chances of getting re-elected. But if you obscure the new cost in a financial construct, tax payers will (initially) blame business for increasing costs.

Don't be fooled, both systems will raise costs!

Enforcement

Under a cap-and-trade model, a central authority (a government) issues emissions licences uniformly to a sub-set of emitters at the start of a term. At the end of the term, they require these emitters to own licenses matching their output for the term. If they do not, a penalty is incurred. Picture a game of musical chairs if you will.
1) How will the government prove an emitter produced 10 tonnes of CO2 and not 5?
2) How many civil servants will be employed to audit these emitters?
3) How will this model scale from the initially small sub-set of emitters to the planned totality of the economy?

A Carbon-tax model is easy to enforce and audit as well as having the benefit of not exacerbating price shocks (explained below). Tax all sources of emissions (coal, natural gas, gasoline, diesel, etc) and no auditing is required.

It's a mentality of top-down vs. bottom-up.

Finance

The most important difference lies in financial implementation.

The free market is designed to buy and sell goods and products. Tangibles like stocks, precious metals, and frozen concentrated orange juice are amendable to securitization. Constructs like mortgage securities, collateralized debt obligations and emissions caps are the antithesis of a product. They are the lack of product.

In recent years, the world has learned that when you separate an obligation from the party who made that commitment through securitization, unforeseen consequences are inevitable (e.g. global financial crisis, illustration).

We are on track to repeat the mistakes of the U.S. financial system in our attempts to foster a new industrial economy built around environmental efficiencies.

What Might Happen?


Due to the psychological nature of trading price shocks are inevitable - cost certainty is needed for economic stability. More importantly, a cap-and-trade model can cause some high polluting producer produce goods at a lower cost than comparative low polluting producers.

A simple example would compare two farmers in California and Southern Ontario selling produce to Southern Ontario. The Californian farmer uses solar panels to run irrigation pumps, and can sell their emissions cap to the farmer in Ontario who does not have solar cells. The fact the produce is grown in an desert irrigated using power from solar panels (which were made using coal power stations in China and shipped 10,000km), and then shipped 3,000km to Ontario is not accounted for.

A contrived example, but it demonstrates what happens when the source of carbon emissions (the fuel) isn't used as the basis for emissions control.

Closing

All governments are investigating some kind of emissions control regime. Let us not repeat the obligation securitization mistakes of high-finance in the green economy we are all looking to bring us out of this mess.

Spent Nuclear Fuel

Like it or not, in Canada we use nuclear power (mostly in Ontario). This source of electrical power has a nasty side-effect: waste from the reactor is possibly the most toxic substance known to man.

The cost of stewardship of this waste grows proportionally with the amount of waste produced. The more nuclear power we consume, the more waste we have to take care of for the coming centuries.

It would be nice if we could just turn the 'nukes' off and cut our losses. But our need for electricity isn't dropping. When talk about electric cars, we need to be honest and realize we're talking about moving our demand for gasoline to a demand for electricity. We will need 3,000 giant wind turbines or PV solar fields for every 1 nuclear reactor - and they will not produce reliable sustained power needed for our businesses and society.

As of this post, the price of Uranium is $65 USD/lb, about the same price as silver. This represents about 10% of the life-time cost of a reactor. This doesn't include the centuries of waste fuel management.

What if we could re-use waste fuel? What if we could re-use it 3, 5, or even 10 times? The CANDU reactor design allows us to do precisely this. We can turn the waste fuel cost centre into an asset and reduce our need for fresh uranium. This processes is similar to enrichment - remove the less than 10% of mass that inhibit fission, and re-use.

Waste fuel from American, Russian, British, and Japanese reactors only need to be cut into shape for a CANDU - even easier.

The CANDU Cycle

Now that there is enough waste fuel in Canada (and the world) to justify construction, isn't it time to consider a waste-fuel processing plant to reduce our mining of uranium? With technology like that, Canada can become a nuclear powerhouse helping countries reduce production nuclear waste. This will create high paying Canadian jobs in a growing sector of the world economy.

Car, Hydro, NatGas charts updated

Check out the links on the left "Graphs 2009-05-08" for new charts showing fuel consuption of our car as well as electrical consuption for the winter with our new Ground Source Heat Pump furnace.

Natural gas consumption has been zero for a while, the gas company come over a put a lock bolt on our meter. No gas bills.

Quirks and Quarks: Talks reality

The CBC's excellent radio show Quirks and Quarks had a guest who wrote a book "Physics for Presidents" and it got people in a bit of a tizzy. Listen to it in MP3 or OGG.

So much was the reaction, the host Bob MacDonald wrote about it in his blog.

Read it, then check the responses from people. My favourite:
Dave from Ottawa
"A kilogram of coal, on the other hand, contains about 1,000 times more energy than an equivalent volume of air blowing past a windmill."
Now subtract the energy it took to extract and transport that coal to the power plant.
My point is that energy density is a misleading measure. Update the article to compare net energy output of the sources.

My comment to Dave from Ottawa:
Now substract the energy it took to mine the iron, refine it into steel, bend and melt it into a turbine and alternator and transport it from Europe to Ontario. My point is that energy density is not the only measure but the single more leading indicator of a fuel's viability.

I repeat my theorem:
For an energy source to be viable, it must be produced from raw materials using only that fuel source.

Example:
If wind power is so great, produce more wind farms from raw materials using only wind power.

This test passes for coal, natural gas, petroleum, and nuclear power. It does not (yet?) pass for wind, solar, hydrogen, or ethanol. Biodiesel is on the fence.

Earth Hour - Consuption vs. Generation

Purpose


Like this blog, I am here to present facts and explain them. In short - the public data shows no less Coal or Natural Gas was burned during Earth Hour. And yes, the Nuclear plants were still going full-tilt (in fact the Bruce-B Generator-5 increased production prior to the event).

Introduction


It's great to "do our part" and not consume electricity. But we need to realize that less consumption does not always result in less pollution.

Sounds like anti-Earth propaganda doesn't it? Let me explain by using Earth Hour as an example.

The notion is if we turn off our lights and use less electricity, we make less pollution. Forget for a second that florescent lights in office buildings are much more efficient than the soft glow of incandescent lights typically in homes. And forget that lighting is a very small portion of the total electrical demand.

The Data


Think of how the electricity is generated. In Ontario there are 5 major fuel types being used for generation:
The Independent Electrical System Operator announced that during Earth Hour Ontario electrical demand dropped by 6% from the calculated expected demand.

And Here's The Catch...


Put yourself in IESO's shoes - you control the leavers that can crank up the generators.
  • Your Nuclear generators can be shut down in about 60sec, but take 3 days to get back up to speed - can't touch them since they're your work-horse generators.
  • Your Pulp&Paper and Wind generators produce a fraction of your capacity - don't bother turning them off.
  • Your Natural Gas and Goal generators boil large vats of water into steam to spin turbines. These monsters can turn on faster than Nuclear, but they still take almost an hour to reach full power. (NatGas is a more complicated than this, but you get the idea)
  • All you have left that you can control for this is to throttle down your Hydro generators which are very responsive to turn-off and turn-on commands (60sec!).


Conclusion


The irony is the fuel source perceived to be the cleanest - Hydro - is what gets turned off during Earth Hour because it's the only thing that can be turned on again as demand returns at the end of Earth Hour.

The graphs of the data provided by the IESO generators support this conclusion.

What would make IESO turn down the real polluters of its generation system? If Earth Hour was an all-day event.

Hotwater from Geothermal

Last night it dipped down to -20C, the furnace was running quite a bit in the afternoon so I took this chance to turn off the electricity to our electrical hot water tank and let the furnace heat our hot water.



Here you see how the tank is hooked up to the furnace. As you can see, the hot water comes out the top of the tank (since heat rises). The furnace draws from the bottom, and returns to the bottom on the other side.

Once the power was turned off to the tank we ran the dish washer, did a sink full of dishes and our daughter had her bath.

2nd GeoThermal Furnace Video (what's inside)

Here's the second video, show what's inside the furnace. There's really only a few parts:
1) The refrigerant compressor
2) The heat exchanger
3) The blower
4) The computer control system

GeoThermal Furnace Video

Here's a YouTube video of my furnace. More to come, busy these days. So sorry.

"The Phoenix has Landed"

My contractor exclaimed to me on the phone in the usual gusto consistent with the stereotype of his cultural background. If you can't politely smile at stuff like that, what good is life?

Geothermal Heat Exchange furnace will be installed Monday/Tuesday next week (2008-06-23/24). In time to break it in a bit over the summer before the winter heating demands arrives.

Drilling Completed

The drilling is done. It was loud. It was dusty. It was awesome!

The drill holes were done at 11 degrees in one direction, and 22 degrees in the other. This is approximate based on my measurements.

Top view, looking down on the roof of the house:


Front view, looking at a cross section towards the front of the house.


Some videos:
Drill through overburden (aka. top soil).


Drilling through sandstone.


Feeding the copper heat exchanger down the 100ft hole.


The target.


The equipment arrives at 09:00.


45min later it's ready to go.


What I see from my living room.


Drilling gets underway.




It makes a mess.


What the drill bit looks like. It sounded LOUD. I measured it at 105dB at 5 meters away. When the drill shaft is pulled up and each link is separated - it would spike at 120dB.


Examine the hole.


Prepare the heat exchanger to go down. Notice the block of metal for grounding in case of lightning strikes.


Send the copper heat exchanger down the hole.


Fill it with silica sand (crushed quartz) up to the rock-overburden interface.


Then fill the top with "hole plug" bentonite. This is a form of clay that seals the top of the drill hole to prevent surface water from getting down deep in the rock.


Repeat 2 more times, and you're done for the day.


Next - we wait for the furnace unit to arrive and final stages of installation take place.

Drilling today

Well, the contractor from Earth Energy called me last week to arrange a time to start drilling for my furnace. "The phoenix has landed" he announced in his usual colourful exclamation.

And about the same time I got an email from a reader of this blog advising me to stay away from them. I'm not surprised since my experience with the owner was been less than reassuring. When the unit is installed, I'll be asking questions and taking notes. Such a niche furnace - it'll be hard to find good maintenance should this contractor go under.

Your thoughts on what info to ask for is most welcome fellow readers. Here's me list so far.
  1. What's the refrigerant used in the heat exchanger?
  2. How much refrigerant?
  3. At what pressure is the heat exchanger filled to?
  4. Make a list of parts inside the unit (small moving parts will likely be the first to break down)

And yes, there will be photos and videos of the mess they'll be bringing down on our house.

Cost of electricity less than zero?!

Fun story on the CBC today:
http://www.cbc.ca/cp/Oddities/080507/K050704AU.html

In short - it was cheaper to pay people to take power than it was to shut down generators.

This is what happens when daytime power consumption is 20-30% higher than in the middle of the night.

If only we could consume power more evenly...?

Most people immediately think - "why don't we store the power in batteries!". I suggest - do the math. The energy to be store is gargantuan!!! Basically there are only two way to store that much energy:
  1. Thermal potential
  2. Gravitational potential

Thermal potential is easy enough to visualize - heat something up to several times the boiling point of water and insulate it until it is need 8 hours from now in the day. Thermal solar power is one example of this. This is why thermal solar power is more attractive for base electrical demand - it can still generate power when the clouds come in.

Gravitational potential does not involve a black hole or a TARDIS - but water. Using power from base load generators at night to run pumps to lift water a few 100ft up a hill or precipice into a large (kilometers wide) reservoir. The gravitational potential of 1 million tonnes of water is far greater than $100 million in batteries. And at a fraction the cost.

Dumb people and the environment

My biggest beef with the environmental craze that's going on right now is how mis-information and dis-information is everywhere. There are so many people out there who haven't thought things through and spout out a load of crap as fact.

The "green revolution" is a perfect example of Quantum Bogodynamics where Bogons and Cluons are interacting - and in my opinion the Bogons out number the Cluons 10:1 right now.

Example 1 - "Tap Water is unsafe, dontchaknow?"
I have a co-worker who started a conversation taking the position that city run tap water is unsafe because the recently published report on pharmaceutical chemicals discovered in tap water of several US cities. Being married to a hydro-geologist (aka. water geologist, aka. ground water scientist) I am privy to her complete confidence in city run water treatment.

Aforementioned co-worker was of the opinion - nay - the conviction that his well water is "pure" because he "got one of those expensive lab tests done" and everything passed.

Thing is - the city of Ottawa performs over 125,000 tests per year on over 350 different parameters while his well is tested, what, once per year? Check the report yourself.

And don't even get me started on bottled water vs. tap water (hint - they're the same thing).

Example 2 - "Compact fluorescent lamps are not better for the environment"
Same co-worker. His argument was:
  1. CFL's don't produce as much heat, increases the heating bill
  2. CFL's have mercury in them and are hazardous - "think of the children"
  3. Hazardous material waste disposal requires going to a landfill - burning fossil fuel
  4. Hazardous material waste days at the landfill are busy - everyone's cars are idling - burning fossil fuel
  5. When he went to the HazMat day, the line up took "so long" that he just left is HazMat at the side of the road and left
  6. The city should collect hazardous waste are the road side so he doesn't have to make the trip.

My responses:

  1. Every dollar spend heating our house using electrical resistance would cost you $0.40 (approx) in natural gas.
  2. The CFLs last for 5 years. Incandescents last for 1. Mercury and other heavy metals are recycled because they are valuable.
  3. Hazardous material water disposal is a once every 5 year occurrence for most households (sometimes never, thanks to hardware store drop-offs). Don't complain about something you do once every 5 years with proper storage - "go when you have enough to make it worth the trip"
  4. See response #3. If you only go once every 5 years, suck it up.
  5. His fifth point revokes is right to talk to me
  6. The city should also pay someone to wipe the poo from my bum so I don't have to do it. But that would not be cost effective. The same argument applies to his point.

Round 2.

Him:

  1. I like soft incandescent light.
  2. I have a chandelier that don't take standard type-2 bulb sizes - do I have to buy a new chandelier?

Me:

  1. CFLs exist with softer, diffused light so solve this problem. We don't live in an autocratic society - shelve your bleeding hart.
  2. CFLs exist on all the same socket sizes as conventional incandescents.

End result:

He still thinks "the man" is out to get him. I still think he others like him will eventually out-breed people like me.
