How to hookup a generator to a home

I got lots of traffic on my YouTube videos on Earth Day - lots of comments and emails too.

The most popular question was "How do you hook that up to a home?" Well, here's a diagram showing how.



Notice that I didn't mention anything about feeding back to the grid. Doing that is can make you some small money, but it's expensive to setup. In place of the DPDT (double pole double throw) switch you have a synchronizer to maintain freqency and phase alignment between your generator and the grid. Usually involves converting from AC to DC then back to AC at a loss of power and money from your pocket.

Tracking Power Generation in Ontario

An excellent site showing the electrical generation in Ontario is www.ieso.ca

They provide a metric dung load of information on:

1. %-age generation by type (hydro, nuclear, gas, coal, etc)


2. Maps showing where all the generating plants are (pdf, page 14)


3. %-age consuption by consumer group (home, business, industrial)


4. Seasonal peak consuptions and average demand by city


5. Historical top-20 peak daysGenerator availability plant-by-plant, day-by-day (2008-04-01)

And the awesomest demonstration of why the internet was invented: Live graphs of today's projected and actual electrical consuption!!!

Interesting things one can gleam from the website:

1. Ontario burns a lot of coal - 20.6% of total installed capacity - but plans exist to decommishon all coal by 2009
2. Ontario has been exporting more power than it brings in over the past two years - but there is still tight dependance on US for even distribution
3. There is a lot of nuclear that never turns off
4. Winter peak electrical demand is 90% of summer peak demand

All in all, very educational

More photos of Mark's Generator

Here are some pictures of the recent videos of Mark's Generator.


Picture 1:
- 12HP 2cyl engine, 8KW 220V AC alternator ESA approved
- currently unused water tower for cooling


Picture 2:
- Flexible Aluminum exhaust pipe
- 2 piston exhaust joined in a Y-joint
- Copper fuel line is wrapped around exhaust for pre-heating (better burn, better flow)


Picture 3:
- 3 fuel tanks (Veg-1, Diesel, Veg-2)
- Flexible Aluminum exhaust pipe
- Copper fuel line is wrapped around exhaust for pre-heating (better burn, better flow)
- Exhaust going out the fron door for now.

Mark's Lister in operation

Here are two videos of Mark's generator in operation.

Added since last post:
1. exhaust pipes vent to outside (flex pipe on left)
2. glow plugs added for easier starting (battery powered - right)
3. 3 40L fuel jugs hung from cieling
4. 3-to-1 fuel valve to select fuel (diesel or veggie)

Still to-do:
1. cooling system
2. muffler
3. sound-proof the shed
4. install electrical cables to his house

With any luck, he'll have a generator working for this spring's thaw-and-melt-and-flood-your-basement season.


Video 1: Single cylinder firing.


Video 2: Both cylinders firing.

M's Generator is getting closer

So M's generator is getting closer to being operational.

Todo:

1. install cooling system (205L steel barrel filled with water/coolant, convection cooling)
2. install veggie fuel lines (currently only using diesel)
3. install exhaust system!

Today we got woodnstuff's man John to come over with the new fly-wheel and between 3 of us we took turns cranking the sucker. With the help of break cleaner from CdnTire (ether is so last century) we got a few successful power strokes. The -10C overnight temperatures made the engine quite cold. M will need to install some glow plugs for winter starting.

M's Generator Coming Together

My long time friend M lives away from the city and when the power goes out - he's not in an area with a high priority for restoring power.

Without electricity his home is at risk of flood, freezing/bursting pipes and other damage. Not to mention his little girl would be stuck in the cold with no water (water well needs power to pump) or warm food (electric range and oven).

With his wife's blessing (I assume) he began building a shed to house a lister engine to power his home. His eventual goal is to sell power back to the grid through OPA RESOP at double the market rate.

Here is the engine mounted on the I-beam frame. The I-beam frame is rested on 2cm thick rubber padding - like this. Then the I-beam frame is anchored into about 1,000 kg (2,204.62262 pounds ...) of concrete.

We got the two fly wheels on (about 90kg each) after much grunting. We figure he's close to getting the engine started. We'll start with just diesel. There are still exhaust, cooling, veggie fuel considerations to prepare. Oh yeah, and the alternator, electrical cabling, throw switches in the house, etc. But for now, we're happy.

Powering a home on the fat of the land

No man is an island. I have a good friend M whom I feed my need to talk about crazy ideas like heating your home without gas, wood, or fuel. We also talk about running a car using waste oil.

We had an agreement - that I would get a ground source heat pump and he'll get a Lister generator powered by veggie oil.

Lister engines were made in Lister England in the 1930's and knock-offs are now made everywhere - especially in India. These engines are very primitive. Hand crank to start, no muffler or transmission. But primitive it good - it can run on veggie oil no problem.

If you strap a large alternator to it - you now have a waste oil to electricity device. Free power.

In this blog I will present how we setup M his very own grease sucking power plant.

First post

This is a first for me. These fancy-shmancy blogs that all these trendy 'kids' have to talk about this and that. So why did I betray my stubbern mindset to avoid being trendy?

Because the stuff I'm doing to my car, my house, my friend's house is just too damn cool. I want to share what I've learned about using waste vegetable oil as car/home/power fuel, furnaces, and other misc things that happen to peak my interest.

There will be photos, videos, howtos, diagrams, and comedy. Let the fun begin.
