are you happy with your wind turbine? - Page 9

So you really don't have a clue. It is also amazing that it seems you
can't go for a single day without the generator.

You are right, I don't have a clue as to how you can read but not
comprehend (actually I do have a clue, you do it to try to make yourself
look good. you are failing). Running the gen everyday is only done in
the heating season when I need heat. Since the veggie oil is free, it's
a cheap, fairly clean fuel source.

Ya gotta laugh. I mean when someone claims first that a product is free
you know that they are lying. TANSTAAFL.

But the real joke is that Steve then goes on to say it's cheap. This is
an admission of cost.

The costs are, if nothing else, picking it up and heating it with wood.
These are both costs as they both involve an energy expenditure.

As they both involve an energy expenditure this actually reduces the
overall efficiency of the generator system.

My point is valid, Steve, you don't have a clue.

Below is my total energy use by the day, week, month and year.

I know where my energy comes from and I know where it goes.

If you can't account for your own energy how can you advise others?

Give wayne back his runners and show us that you actually know what you
are doing.



You accused me of not being able to provide real numbers for what I do.
Despite the fact that you know I can and have done so on many occasions.

I do so again. These are the numbers for all the energy I use. Day,
Week, Month and Year in kWhs

Source        Day     Week    Month     Year
Petrol        12.71    88.98    381.36     4639.93
LPG car        40.29    282.03    1208.71     14706.01
LPG house    14.89    104.24    446.76     5435.59
Wood        44.45    311.14    14333.44 16223.52
Electricity    1.20    8.40    36.00     438.00

Some of these are averaged as for example I don't use petrol every day
or drive the car every day. These numbers do not include what I eat.

Notes;

Petrol runs the chain saw, motor cycle, tractor, large and small generators.

Energy values. Petrol 32.0 MJ/L, LPG Car 25.4 MJ/L, LPG House 49MJ/kg,
Wood(20% moisture content) 16MJ/kg.

Electricity input is ~1.2 kWhs/day. I use this number for the use as
well because it is what is required to keep the batteries charged.

It's not hard, Steve, to work these things out. You have a system
similar to mine in energy sources.

I, and I am sure many others, are interested in what we really do.

The question remains "Numbers or Runners?"

yes, picking up the free oil costs us about $0.30 / gallon after
filtering. Logical folks understand free to mean we are not charged for
the oil, but that does not mean there is no end to end cost. For
instance, freecycle is a good source for free goods, but you still have
to pick them up. However, most folks here realize your goal is to not
educate, but to obfuscate.

Well Stevie, welcome to Efficiency 101

Efficiency = Useful energy output/input energy.

n = Pout/Pin

Where n = Efficiency ( no units, expressed as %)
Pout = the useful power output
Pin = the total power input


EFFICIENCY-Multiple steps

n(total) = n(1) X n(2) X n(3)\dots X n

Where:


n(tot) = the total efficiency of the process
n(1) = the efficiency of the first step
n(2) = the efficiency of the second step
n(3) = the efficiency of the third step
n(n) = the efficiency of the nth (last)step

(n = eta)

In your case this would be on the order of;

n(1) the efficiency of the IC engine used to pick up your "free oil"
n(2) the efficiency of burning wood to heat the oil
n(3) the efficiency of the the engine burning the oil to run a generator
n(4) the efficiency of the generator being run by the engine
n(5) the efficiency of the battery charger
n(6) the efficiency of the battery
n(7) the efficiency of the inverter

The only person obfuscating is you.

TANSTAAFL!

This is education.

How can you expect anyone to take your advice seriously if you can't
account for your own energy use.
