The program claims that there are many examples of greener products. The 2014 Ecomagination report boasts that they have some of the most efficient products in the world. Some examples include the Tier 4 Locomotive, which decreased emissions by approximately 70% or more over their Tier 3 product and saved customers an estimated $1.5 billion. The HA-turbine is the largest, most fuel-efficient gas turbine in the world, at more than 61% efficiency. The LEAP jet engine gives customers a 15% improvement in fuel efficiency versus its predecessor and also provides improvements in noise and emissions, and the lowest overall cost-of-ownership in the industry—a critical aspect to the airline industry. The city of San Diego employed Ecomagination’s “intelligent” lighting system, called LightGrid, which links its streetlights to the Industrial Internet. The city replaced more than 3,000 light fixtures with GE LED lights, their intelligent street lighting systems can reduce electricity consumption by 50–70%. If you were in the market for one of these products, surely you would take a good look at Ecomagination products. The key messaging here is that it saves you money while providing significant environmental improvements.

You may wonder about the importance of this CMC advancement. As of May 2016, GE had confirmed orders for 10,000 LEAP engines valued at ~$140 billion. Each engine uses 18 MI-CMC shroud segments. Production is projected for 36,000 per year by 2020. Presales for the GE9x engines are for 700 engines at about $29 billion.

In addition to these digital changes also new manufacturing technologies arise. Besides progress in ‘traditional’ technologies based on computer numerical control (CNC) – like milling, turning, or grinding (as indicated, e.g. in Suh et al. 2008) – additive manufacturing technologies like 3D-printing or laser sintering made a great leap forward in their development (Calignano et al. 2017). A rising number of researchers give attention to the proclaimed ‘additive revolution’, advancing the technology from being applied merely in development, prototyping, or rapid tooling to a serious alternative to conventional manufacturing for more and more applications, e.g. for products with complex and personalised geometries, respectively (Battaïa et al. 2018; D'Aveni 2015; Gao et al. 2015; Jayaram and Vickery 2018).
