How to Make a Solar Hot Water Heater for under $100

How to Make a Solar Hot Water Heater for under $100

You wouldn't guess that in the tropics having hot water was so desirable, but at our elevation, it gets quite chilly for me in the evenings. During the rainy season the nights can get particularly cold and if you've been in the rain working, a rejuvenating warm shower is just the ticket!

Over the years we have trialed two different types of hot water systems: composting hot water and solar hot water. I've personally installed and used both systems and would like to share what I've learned.

Endeavors to End Propane: Local Fuel Sources and Efficient Cooking Technologies

Endeavors to End Propane:  Local Fuel Sources and Efficient Cooking Technologies

Cooking food can make it tastier, easier to digest and absorb nutrients, and safer and healthier to eat. Cooking at the Ranch happens multiple times a day, and on some days, pretty continuously throughout the day. We generally have a lot of hungry bellies to fill! Over the decades we have been steadily reducing our use of propane to meet our cooking needs.

6 reasons to use a biodigester as a low tech, off the grid, renewable energy source for cooking

6 reasons to use a biodigester as a low tech, off the grid, renewable energy source for cooking

For almost two decades now, Rancho Mastatal has been working on creating a more sustainable lifestyle by researching, developing, and teaching about more efficient ways to build, grow food, cook, and live as a community while reducing the impact these activities have on our environment.

As cooking is one of the most energy-consuming activities within a house, we find it relevant to implement an alternative renewable energy source to satisfy one of our guests’ favorite moments of the day: meals. With that perspective, we built a biodigestor 8 years ago.

Transforming Human-waste into Fertilizer: Compost Toilets

Transforming Human-waste into Fertilizer: Compost Toilets

You likely grew up with flushing toilets, seeing your poop as something to dispose of, but you might also be one of those who agree that humans can only thrive once we live in harmony with nature. The zero-waste movement is in a sense, a yearning to imitate nature where there is no such thing as waste; one organism's excrement is another's food. Compost toilets turn human "waste" (discarded feces and urine) into soil fertility as humanure (food for micro-organisms and fruit trees) - the actual human waste is everything that cannot decompose: cigarette butts, plastic-sixpack rings, deodorant cans, batteries, the five billion gallons of polluted drinking water we flush down our toilets everyday, and the millions of tons of organic material dumped into the natural environment year after year.

The Biodigester

The Biodigester

It's 5.30 am in the dewy morning rainforest of Mastatal – the cacophony of squawks and birdsong remind us that the winged beings have begun their daily business of foraging for themselves and their young, the toads have tucked themselves into the nook of a tree or within a pile of leaves to avoid the relentless heat of the new day, and one by one the guests at Rancho Mastatal stretch and yawn their way out of their abodes and ease their way towards their first cup of coffee.

Contemplating an Uncertain Future: The Ranch and Climate Change

Contemplating an Uncertain Future:  The Ranch and Climate Change

Climate change, after decades of lulling at the bottom of the news cycle, has belatedly made it into the headlines as increasing numbers of people become aware, convinced and concerned about the environmental and social impacts of the Earth’s evolving atmospheric conditions.  I frequently think about disrupted weather patterns and what my role in this unfolding story should be.  

No Pickup, No Problem: Social Capital Trumps a Shitty Situation

No Pickup, No Problem: Social Capital Trumps a Shitty Situation

My hands are grappling the rumbling, rusty wheelbarrow handles, and as we walk half a mile through the village, everyone can hear the five Rancho apprentices clunk on through. In a village of 120 people, your whereabouts are everybody's business. Don't worry, I want to say, this will all make sense soon. They'll be having a chuckle by the end of the day. For now, we are five warriors defending alternative energy. We are making the best use of our woman power (and Dan power) when the white pickup truck is out of commission. We are going to pick up poop.
