The work currently being done involves construction of streets, water and wastewater, storm drains, electrical power and distribution and communications facilities.
At an initial cost of more than $18 million, crews in Texas are working to expand what’s been described as the world’s first truly urban commercial spaceport. Infrastructure work is under-
way on more than 150 acres of Houston Spaceport, located on the southeast side of Ellington Airport, a mixed-use, general aviation airport. “The Houston Spaceport is unique among the other federally licensed spaceports,” said Arturo Machuca, Houston see SPACEPORT page 46
Team Looks to Turn CO2 Into Pre-Fab Concrete Carbon Upcycling UCLA/CO2 Concrete, one of 10 teams competing in the final round of the NRG COSIA Carbon XPRIZE, is hoping to win $7.5 million for demonstrating the most practical technology for turning carbon dioxide
emissions into a useful end product. Whoever wins the competition in 2020, the world has already won, due to the team’s innovative solution to the excesses of CO2 produced by power plants and other heavy industry plants.
The UCLA team plans to turn carbon dioxide from flue gas — the exhaust gases from a coalburning power plant — into prefabricated concrete blocks called “CO2Concrete,” a trademarked name. The goal is to produce up to The UCLA team plans to turn carbon dioxide from flue gas — the exhaust gases from a coal-burning power plant — into pre-fabricated concrete blocks called “CO2Concrete.”
10 tons of the product each day. The blocks will then be used in demonstration construction projects. This innovative process takes CO2 from coal-burning power plants and heavy industry and converts the waste gas into pre-cast concrete building components while minimizing the use of traditional cement, said Gaurav N. Sant, a professor of civil and environmental engineering and of materials science and engineering and director of the see CONCRETE page 36
