Oregon State University is providing free access to the knowledge and tools needed to help combat climate change and other world issues in a massive open online course, or MOOC, on sustainable landscape design this spring.
The four-week course, Intro to Permaculture, is a public education project that will enable students worldwide to learn about and design sustainable landscapes and ecosystems in a highly interactive way.
The class runs May 1-27, 2017, and is open to all for free.
The practical use of permaculture design techniques makes the course information easily applicable to a person’s life, said instructor Andrew Millison.
“I’ve seen exponential growth in permaculture in recent years because it directly addresses many of the issues that are on people’s minds, such as climate change, food security and the alleviation of poverty,” he said. “Permaculture offers solutions to these issues, and this course gives people a way to make a positive impact.”
Using interactive web apps, satellite imagery from Google Maps and Millison’s digital animation drawings as a guide, students will create their own landscape design site online through a series of detailed mapping exercises. By the end of the four weeks, students will be able to articulate major design strategies for each climate.
In essence, the course aims to help people see the world like never before.
“Permaculture gives people a new lens with which to see the landscape,” said Millison, who has 20 years of experience in the field. “The high-production visual element we’ll use in this class will really bring the activities to life in a way I’ve never seen before.”
The development of the MOOC is a joint effort of Open Oregon State, OSU Professional and Continuing Education, Oregon State Ecampus and OSU Extension and Experiment Station Communications.
“OSU’s strategic plan calls on us to be responsible stewards of environmental and social systems, locally and globally,” said Open Oregon State Director Dianna Fisher. “By working with the other units to develop and offer this course for free online, we can help learners everywhere do their part to address key world issues.”
This is Oregon State’s third offering of the permaculture MOOC. The course was initially offered in May 2016, and more than 16,000 worldwide participants enrolled from nations such as Australia, Argentina, Poland, Botswana, Germany, India and South Africa.

Add 1 glass of water and 2 tablespoons of salt, use the lamp for 8 hours.
Cost Effective. There are over 7,000 islands in the Philippines and most of these islands do not have access to electricity. We want to eliminate the sustaining cost in areas that rely on kerosene/battery powered lamps and candles as their main source of lighting. And to provide a more efficient light source for people who use lamps and candles as an alternative source of lighting. Replace consumable every 6 months! Using SALt lamp 8 hours a day every day will give you an anode lifespan of 6 months. Use this as an alternative light source will prolong the life of your anode for more than a year.
Watch the LEDs glow! Light your way with a lamp powered by saltwater.
Safe. There are no materials and components inside the lamp that may cause fire accidents. One less thing to worry about for families that rely on kerosene lamps as their main source of lighting. This lamp uses the science behind the Galvanic cell, the basis for battery-making, changing the electrolytes to a non-toxic, saline solution — making the entire process safe and harmless.
Charge your smartphones! For emergencies, you can charge your smartphone using this lamp. Just plug in your USB cable.
Environmentally Friendly. According to a study conducted by the United Nations, The Philippines ranked 3rd as the most disaster prone country in the whole world. And in disaster situations such as super typhoons, earthquakes — a steady supply of food, drinking water and sustainable light source is very essential. The importance of the product in terms of short term usability and as a long term household staple can be attributed to how easy and common the elements needed to power the lamps are. It also does not emit harmful gasses and leaves minimal carbon footprint making it very environmentally friendly.
You can also use the ocean water to power up your lamp!
If you are living along the coastline, no need to create your saline solution, instead… use the ocean water to operate your lamp.
Easy to Use. The salinity of ocean-water can operate your lamp. Use the ocean-water to power up your lamp and it will give you 8 hours of running-time. Salinity is expressed by the amount of salt found in 1,000 grams of water. The average ocean salinity is 35 parts per thousand. Store ocean-water in bottles and use them to power up you lamp anytime, anywhere.
“They’re for the nooks, the crannies, the rooftops,” said Nick Halmos, the founder and CEO of Cityblooms. “You can set it up in a parking lot and there are no permits. All we need is a pocket of land, some water, and an extension cord.”
The Cityblooms units look like a cross between a greenhouse and a raised bed. They are minimalist in design. But there’s a lot going on underneath the hood. There are integrated fans, sprayers, drains, pumps, and filters so that each unit can maintain just the right temperature and moisture levels. Farmers can control everything remotely from a tablet. “Essentially it’s a modular robot for growing food,” Halmos said. “Sometimes we call it a growbot.”

Dr. Maria Neira of the World Health Organization: “The risks from air pollution are now far greater than previously thought or understood, particularly for heart disease and strokes. Few risks have a greater impact on global health today than air pollution; the evidence signals the need for concerted action to clean up the air we all breathe.”
