Making CO2 Useful

Energy Central : "Technology that promises to economically sequester carbon dioxide by turning it into fuel is poised to make the move from research labs to the development stage.
Carbon Sciences, a California startup, is planning a prototype project for early 2009 that the company will use to evaluate the challenges of commercializing its new conversion technology.
In many past efforts to break apart carbon dioxide for other uses, the processes required high temperatures and high pressures. As a result, many efforts used a large amount of energy, making the operation at best less attractive and at worst economically impractical. Additionally, the equipment necessary to perform the transformation had to withstand the high temperatures and pressures. This drove up the price of building a conversion facility."
