Four4Entrepreneurship will offer, for the first time this summer, the Entrepreneurial Impact International Summer School: Billion Euro Projects to Foster Societal Change (a big name for a big project!). The EIISS will encourage entrepreneurial thinking in order to provide innovative solutions to worldwide social problems. As the name suggests, the projects must provide participants with an idea so far-reaching that the impact on society would be significant enough to entice at least a billion Euro in investments or can earn or save at least a billion Euro while fostering societal change. Examples of possible projects range from wind energy systems for private homes, to a fresh look at the benefits of the blimp (Zeppelin) on our environment, to revamping the primary school system in Germany, or even the next Google.
