Here is an interesting engineering summit that is being held in Cambridge Ma. at MIT:
The following IDDS events are open to the public.
11:30 am-12:30 pm,MIT room 66-110
Keynote Speaker: Paul Polak, founder of International Development Enterprises, will speak about design for affordability and the design revolution needed to lift out of poverty the two billion people who live on less than a dollar a day.
(and there are many more public events at this link)
Of all the engineering problems out there … this is one of the most intriguing!
UPDATE: Here is a blog entry about Paul Polak at MIT
I did notice that the event that I posted happened in the past, but the conference is ongoing this month.
