Yes / This article explores the relationship between sustainability strategies and future energy needs, supply chains need to reduce their CO2 emissions through developing their green credentials and improving performance. Knowledge management (KM) is an enabler to support collaboration efforts. The SCM and KM areas have largely focused on improving organisational performance. While the latter has yielded successful outcomes in different sectors, there is still a scarcity of research on identifying influential factors highlighting those aspects which may enable green supply chain collaboration (GrSCC), thus leading to sustainable energy futures and carbon-efficient production. This paper examines the role of KM in facilitating GrSCC. Through the identification of key factors extrapolated from the literature, a model for implementing GrSCC using a futures-based perspective is proposed. This paper inductively demonstrates the relationship between identified GrSCC factors through fuzzy cognitive mapping technique. Findings support a futures-based perspective that enhances understanding and refines forward-looking strategies for GrSCC.

One of the possible ways, how to ensure the necessary electric energy to the future is by the thermonuclear synthesis. Systems that deal with this problem are called stellarator or tokamak. In my work I describe the working principle of the tokamak and its possible future evolution. More precisely I deal with particular tokamak that was brought from Culham to the Prague and its power supply, which became a problem. It is tokamak model COMPASS D. My work consists in power supplying of tokamak reels and power elements in its supply way. However it is just a test gear, which has a long way to the successful end, wich is power supplying instead of power burning. It is just a test gear on which are various tests and analyses carryed out nowadays. Results of these tests will be used for another research and to improve the results of this or other facilities.
