Another great project by Wolfgang Buchner of EMAS in Bolivia, the inventor of the EMAS pump. I want one of these! This ferrocement boat could be built for around $50, depending on where you live. (Adjust for costs in your area.) Try finding a sturdy boat for that price. And it’s so simple to do! Once you’ve mastered the basic steps, you could build many other types of boats. What about a houseboat made one section at a time? This would be a great cottage industry product for certain areas.

Ferrocement boats can last over 100 years according to The World of Ferrocement Boats.
Don’t want to use Portland cement? Try to locate geopolymer cement in your area. (Search the geopolymer site for suppliers.)
Note: the same ferrocement skills can be used to build roofs or even entire houses.
