Transition to Clean Technology
We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation– in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to clean technology can be diffi cult both because clean research must climb several rungs to catch up with ...
متن کاملTechnology for the Production of Clean Electronics
This paper describes the experience gained in Sweden in connection with early phase-out of CFC-113 in the production engineering industry. It concentrates particularly on the phase-out of CFC-113 in the production of PCB assemblies, although parallel applications for cleaning of precision components, metal cleaning and : to some extent the phase-out of l,l,l-trichloroethane are also considered....
متن کاملHow often should you clean your room?
We introduce and study a combinatorial optimization problem motivated by the question in the title. In the simple case where you use all objects in your room equally often, we investigate asymptotics of the optimal time to clean up in terms of the number of objects in your room. In particular, we prove a logarithmic upper bound, solve an approximate version of this problem, and conjecture a pre...
متن کاملNo-Clean Reflow Process Implementation
ne of the corporate goals at AT&T is to eliminate chloroflurocarbons (CFCs) from its manufacturing operations by the end of 1994. Many alternatives have been implemented to meet this objective, including noclean wave soldering using low-solids flux, aqueous cleaning of water-soluble flux, aqueous cleaning with saponifiers and semiaqueous (terpene) cleaning. Part 1 of this article describes the ...
متن کاملGTL Technology for Production of Clean Fuels
There is a world-wide demand for clean, reliable and affordable energy. New technologies are needed to produce more oil and natural gas from ‘stranded’ locations. This work is based on gas to liquid (GTL) conversion of natural gas through Fischer-Tropsch (FT) synthesis. Fe & Co based catalysts of varying compositions were prepared in the laboratory and its performance was checked for the FT rea...
