Course Description: [jump to the syllabus]

This class introduces students to concepts of renewable sources of energy. The first third of the course begins with a general look at the topic and invites discussion of its political and social ramifications. At the same time, students will be introduced to a handful of technical concepts that supplement the skills learned in physical computing. These skills will allow the student to monitor, harvest, and store small and/or intermittent sources of energy such as those from solar cells, turbines, and other sources. For the remainder of the class the students, working in groups, will create projects that utilize a shared renewable resource, in this case a 80W solar panel on the roof of 721 Broadway. The finished projects will be displayed in an on-floor installation.

Goals:

1. To develop a broad perspective and nuanced understanding of renewable and non-renewable energy generation, storage and consumption.

2. To become well-versed in the current state of the art in energy generation and storage, as well as near- and far-term technologies that may impact the field.

3. To gain the skills necessary to create projects utilizing novel environmental energy supplies, and to measure and monitor the energy usage in those projects.

4. To develop a large-scale, community-based collaborative project utilizing a currently available renewable energy supply.

Assignments:

1. Solar System. The bulk of the coursework involves proposing, refining, and implementing projects to utilize a small photovoltaic array installed on the roof of the building. The 80W panel will charge a 80 Amp-hour battery and provide AC and DC electrical outlets. Students, working in groups, will create projects that use that energy supply to be deployed on the floor. Students will brainstorm and propose ideas by the second week, and throughout the semester the concepts will be refined and reworked. In the end, the projects should demonstrate technical excellence, creativity, and a thoughtful, integrated consideration of the topic of renewable energy.

2. Micropowered Thing. Students will also individually develop simple, small-scale projects that run on energy scavenged from the environment. Examples of potential projects include BEAM-style solar robots or an LED display that runs off a hand crank. See the project brief.

3. R&D - Reading and Discussion. Students will complete a large amount of reading for this class. Various articles and papers, ranging from Buckminster Fuller to the Department of Defense, will be assigned. At times, different readings may be assigned to different groups depending on that group's direction. Students will be expected to focus on specific issues and educate the class, so that we can cover more ground than would be otherwise possible.

Guests:

Throughout the semester guest experts will visit the class. The guests will present information on their area of expertise, and will also serve at times as a critical audience for student project presentations.

Intro During the first five weeks we cover a lot of ground. We'll look at the most general readings on the field of sustainable energy, and discuss energy from a global perspective. We'll learn about the various ways energy is generated and stored, focusing specifically on electricity. We'll cover the fundamental ways electricity can be generated - induction, photovoltaics, the seebeck effect, etc. We'll look at ways people are seeking to harvest tiny amounts of energy from footsteps, body heat and sound. We'll measure the energy consumption of the day-to-day objects in our homes, convert old p-comp projects to run on batteries and observe their performance, and create our own energy sources to run a simple project.

A Big Picture: Energy in General and Electricity in Particular

Our planet's only energy "income" is solar - the energy that beams down to us from the fusion reactor of our sun. What happens from there is where things get interesting. In this first class we'll cover we'll look at Earth's energy income (as well as its accumulated energy "savings") and follow it to its various manifestations.

From this discussion we'll observe that energy is easily transmutable from one form to another. We'll take a closer look at electrical energy and cover the fundamental ways electrical energy can be generated. An interesting fact - all the ways we know of to generate electricity were discovered in the 1800's except two: the electro-kinetic effect results when water passes over special nano-structures and was discovered last year; and the electro-chemical effect, while credited to Volta in the 1800's, appears to have been exploited by artifacts found in Baghdad dating back to 200BC.

Assignments:

1. Come up with three ideas for projects to utilize the solar panel on our roof. Give no consideration whatsoever to the feasibility of the projects - just come up with ideas that you like and would like to live with on the floor.

2. Revive an old pcomp project - any project, but ideally one that's small and self-contained. If you don't have one, throw together something simple - it could the blinking LED program, or if you're feeling more ambitious, something with a motor or two.

A little picture: Micropower harvesting

Last week we were thinking big; this week we'll think small. We'll look at some of our own pcomp projects and measure their power consumption to get a sense for the scale of energy usage we're working with. We'll also review basic terms and units used in talking about energy. Then we'll look at a group of projects - wireless sensor networks, simple robots - that scavenge power from their environment via heat, light, even vibration.

Here's documentation on the circuits we looked at in class.

Assignment:

1. Pick any of the ideas for the solar project from class today and develop it further. Be prepared to discuss in class.

2. Measure and record the power consumption of your pcomp project (we started this in class). Email me the results, and I'll compile them for future reference.
