Welcome to the home of the Michigan Tech Open Sustainability Technology research group housed within the Departments of Materials Science & Engineering and Electrical and Computer Engineering. We are interested in exploring the way solar energy can be used to provide clean sustainable electricity through photovoltaic devices and how the sharing of open source hardware and software can create sustainable and equitable means of production. See recent open access publications.

David Denkenberger and Joshua Pearce, Feeding Everyone No Matter What: Managing Food Security After Global Catastrophe , Academic Press, 2014.

Feeding Everyone No Matter What
presents a scientific approach to the practicalities of planning for long-term interruption to food production.

The primary historic solution developed over the last several decades is increased food storage. However, storing up enough food to feed everyone would take a significant amount of time and would increase the price of food, killing additional people due to inadequate global access to affordable food. Humanity is far from doomed, however, in these situations - there are solutions and this book outlines how to solve the problem.

What if everyone has access to inexpensive scientific research tools?

Is that even possible? Want to be the first to find out? Join us.

How would global society change if everyone had access to abundant low-cost renewable energy via solar electricity, open source 3D designs and an affordable open source 3-D printer like the RepRap?

If we can use any material to make any object we desire- even steel?

If we start in the schools - would children learn more and faster if they were encouraged to flex their own creativity?

What if open-source 3-D printers could make common products less expensively than a sweat-shop? Cheaper than the dollar store with better than Nordstrom quality and customized just for you?
