At first glance, this photo may just look like two women hanging out in an ordinary cement box. But no, this is no ordinary box, and these are no ordinary women.
First, the women are extremely talented engineers and great people to boot. Alissa just got her MS in Materials Science at Berkeley, and Corrina is an Australian mechanical engineer/”retired” investment banker.
Second, the box is made of paper-crete–a lightweight more ecologically friendly material than normal concrete. Third, the box is the frame for an innovative design idea that Alissa and a team from Berkeley developed. It is a prototype of a solar hot water heater that will cost about $75 here in Guatemala.
