Researchers at the Iowa State University Structural Engineering Research Laboratory have developed new wind towers they call "Hexcrete" towers which are made of precast concrete. Sourcable's Marc Howe takes a look at the new towers and their capabilities.

The towers are capable of rising higher than the 80-meter stell wind towers that currently appear in Iowa meaning that they will be able to harvest the greater wind power found at the higher altitudes. But that's just one of their benefits:

In addition to enhancing the energy generating potential of wind power facilities by enabling them to rise to greater heights, the use of precast concrete will also make it far easier for developers to build the turbine towers. The precast columns and panels that form the hexagonal segments of the completed tower are easier to transport to construction sites than conventional building materials,
