Our last trip in Colloquium was to the
ECHO Global Farm and Research Center, which does research and experimentation with farming permaculture techniques to provide help to the third world. This is both Environmentally and Socially sustainable, because the techniques which are presented are more environmentally friendly than the old ones, and their use helps people in less developed countries.
- What are your impressions of ECHO field trip?
I think ECHO is really cool and I want to do service learning there. I think their mission is neat, and I like the fact that the do research which has a clear, real world application to it.
- What is your experience growing plants or gardening?
I've grown a few plants before. It really isn't that hard: plant 'em, maintain 'em, and harvest when ready.
- Could you grow any of your own food like many people around the world have to do?
Yes. Given farmland, plantables, and time, I could probably scrape some together. Actually, I've been planning on getting some cultures for edible mushrooms (like the kind you find in the store) and growing them in a plastic box in my apartment. The drawback, though, is that using a global economy to get your food gives you alot of 1) reliability, 2) variety, and 3) ease of access.
Have pictures!
These are Rocket Stoves, one of my favorite applications or thermodynamic physics. It is a super-eficient wood-furnace which can burn very clean fires at high heat with very little wood.
Apparently there were problems with smoke-inhalation from normal open wood-fire cooking in 3rd world countries. ECHO designed some Rocket Stoves which could be easily supplied to them to fix this problem. Not only do the furnaces give off very little smoke, they also require much less wood than normal fires.
What wasn't explained that I felt would be interesting is how these things work. Basically, the burn-chamber has a high, heavily insulated chimney, meaning it gets really hot inside and burns the wood more fully. Actually, it burns the wood so efficiently that it INCINERATES the smoke and ash, making the final exhaust mostly carbon-dioxide and water-vapor. Thus, the Rocket Stove is about 90% efficient when it comes to burning wood, compared to the typical 25% of a normal wood stove.
A greater, yet unrelated design based on this design is the Rocket Mass Heater, a super-efficient house-warming system which burns scrap-wood to heat a large area in very cold climates. It is very popular with permaculture enthusiasts and backyard-engineers in the northern US and Canada. Here's a picture.
Have some extra pictures now!
Chapin Drip irrigation Bucket: 1 meter high, 100 feet of gradual irrigation.
Bamboo is Fun!
Bananas are a Herb.
This pond has edible fish in it, fed by algae growth, which is fed by duck crap. Ducks are edible too. Note that the pond is relatively clean, probably from all the algae filtering the water and all the fish eating the algae...
Chaya: it's good for you, unless you eat it raw, in which case it's Cyanide.
Gooooaaaaat.
Worm farm which farms "red wrigglers", a good soil aerator and rejuvenator. The bucket collects "worm juice", the nutrient-rich run-off from the farm for fertilizing plants.

Rice Paddy. Rice is best grown in an are which is only flooded most of the time and at a certain depth. It's delicious, nutritious, and easy to grow.
This is a Turken, a hearty bird which is good for cleaning the soil and fertilizing it with droppings.
"Wick Garden", set up for urban environments: can be made on solid rock using trash. All it takes is carpet to root in, a slow-drip bucket to keep it moist, and a covering to protect the roots.
Oh, and here are some low-cost home water filters.
