Sean Bonner

Measuring environmental impact

So, what's the big idea?

Sean is working on Safecast, building open hardware, open source software and open systems to empower people with data about their environment, and the tools to both collect and independently verify that data. The initial focus is radiation levels, with the intent to expand into air quality over time.

We support Sean because everyone should have access to the most reliable, up to date information about the environment in which they live. This project enables that by developing, and quality assuring, open hardware sensing tools and gathering the data to support better decision making at all levels.

Sean Bonner's flash grant nominations

Twice a year we award a number of small grants to a collection of social change agents, no strings attached, in support of their work. We call these Flash Grants and recipients are selected based on nominations from our Fellows. Each award is worth $5,000.

Spend breakdown

At the heart of our co-investment fellowship model is the principle that Fellows continue to invest in their own ideas. The Foundation amplifies the Fellow’s investment by matching it at least tenfold, along with covering the cost of their time for the year.

The figures you see here do not reflect each Fellow’s fellowship year funding, but rather the funds unlocked within our financial year, as the fellowship years start either March or September and Fellows are not required to spend the available funds proportionately throughout the year.
