Bike power: version 2 – field test

Bike power complete. Bike, bike stand, 3 phase rectifier, capacitor,  6 Amp solar battery charge controller, 12V bulb.

The bike ( on a bike stand ) were attached to the 3 phase rectifier and the 1 Farad capacitor to produce 12V DC.

The wheel is a  200 W 36V wheel so the bike could only be operated at a low ( comfortable) speed to prevent too much voltage and too much current.

A 12V 50W dichroic light bulb was added to show it was really working.

capacitor at 13.6 Volts and 50Watt 12 Volt dichroic light working.

capacitor at 13.6 Volts and 50Watt 12 Volt dichroic light working.

PV charge controller added using the bike as the power input instead of the solar panel and battery charger was used.

Probably best for charging a small device unless you want to pedal the bike for a long time.

Future additions:

36 to 12 volt step down for a higher current lower voltage system.

replace the back tire with a smooth tread tire.

Paint can rocketstove: field test

Rocket stove made from a paint can and 3 smaller 300 gram food cans. Small rocks used to create gap between pot and stove

Rocket stove made from a paint can and 3 smaller 300 gram food cans. Small rocks used to create gap between pot and stove

This rocket stove was was constructed out of a 5 Liter ( 1.32 US  gallons ) paint can and 3  x 300gram  ( 10 ounce) food cans. The grey paint was not fully removed from the can and some is still visible. I would recommend that if a paint can was used the paint is completely removed with an appropriate solvent, turpentine or water depending on the type of paint base. If a solvent is not available the can can be heated in an open fire to burn out the remaining paint.

Boil time for 1 liter of water approximately 10 minutes.

dry wood ash was used as insulation.

Some small rocks were use to create the pot stand.

The paint can handle was left on to create an easy way to move the stove.

Addition of the fuel shelf helped the stove produce better air flow an prevents over filling with wood fuel, the shelf was held securely in place with a small rock.

Complaining does not help

Complaining will not make a bad situation better.

I went for a hike recently.
The brief for the journey was that we were to go about 3 km on mostly dirt roads to a creek.
The environment was dry Australian forest, mostly eucalyptus trees.
Thinking that the creek would be full of fresh water I foolishly didn’t take any water.
The journey was mostly down hill on the way there. The weather turned from warm to hot and humid.
The creek turned out to be a largely stagnant trickle. I had no way to purify the little water that was there.
Fortunately my companions had brought some water with them, but on the way back to camp we quickly ran out.
I was beginning to suffer the effects of dehydration and heat exhaustion. I felt very tired and even a few minutes walking was exhausting.
We stopped many times on the way back to the camp for me to recover some strength.
My friend asked me on the way back during one of our many stops ” What’s the most important thing for survival?”

Immediately I said “Knowledge”

Had I known the water in the creek was not drinkable I would have taken water.

Had I known the weather would become so hot and humid I would not have carried a jacket in my bag.

Once we had arrived back at camp we all drank lots of water and rested.

My friend commended me on not complaining about my obviously exhausting return journey.

I said ” Complaining never helps, so there’s not point in doing it”

He nodded knowingly.

Hearing the complaints of other people simply converts their problem into your problem.
It multiplies their irritation and makes that person your irritation.
One person complaining a lot can really destroy the morale of a group,
and then people will start arguing and fighting rather than attempting to solve the real problems they are being faced with.

So in the forest (or other places away from civilization) there will be hardships,
how you deal with them physically and emotionally is your choice.

Occasionally the person suffering will be you, it’s easy to ask people to not complain when you are not the person suffering.
When the suffering person is you, remember to not complain, you won’t be respected for your weaknesses, but you will be respected for being laconic.
