Miniaturisation is not new, but manufacturing mechanical, electromechanical and fluidic components on a micro scale is rapidly developing into a recognisable industry in itself. Alistair Rae reports on a selection of the latest developments in this exciting field. Over the past few years a new industry has developed to serve the growing demand for micro-manufacturing. While miniaturisation has been ongoing since the commercialisation of the transistor some 50 years ago, it is only recently that it has been viable to manufacture high volumes of mechanical and electromechanical components with features in the sub-millimetre range.

The battery technology for plug-in HEVs and EVs (both fixed and removable) has evolved tremendously over the last decade with the introduction of lithium-based batteries complementing lead-, nickel- and sodium-based technologies. These technologies will all continue to have a significant impact on electro-mobility as they may give cost and/or performance advantages for specific applications, for example as start-stop and hybrid solutions. The selection of a technology depends on the requirements for performance, life and cost for a given application. Given the diversity of possible operating modes, there is no one battery system or technology that covers the entire range of application needs sufficiently. On the contrary, different battery energy storage technologies exist and each of them has a role to play in the future as the best solution to the needs of a system depending on their specific attributes: * Lead-based: for start-stop micro application, up to mild HEVs * Nickel-based: for HEV applications only * Lithium-based: for HEV, plug-in HEV and full EVs * Sodium-based: for Plug-in HEV and full EVs

"He concludes that standard macroeconomic factors alone (growth, interest rates, global growth, and global financial market volatility) fail to fully explain the recent investment deceleration. He further concludes that while the importance of structural factors in explaining the recent weakening of aggregate investment is not entirely clear, at the micro level, panel data analysis suggests that improving the business environment by reducing costs of doing business, deepening the financial system, and developing infrastructure, could stimulate corporate investment." The IMF's (2013a) recent staff report on India argues that several causes of weaker growth seem to be of a supply-side nature. The following key factors are listed as possible contributors to the recent investment slowdown: Rising policy uncertainty. In particular, high profile tax policy decisions announced in the 2012/13 Budget have reduced foreign investors' interest in India, while the increasing difficulty of obtaining land use and environmental permits have raised regulatory uncertainty for infrastructure and other large-scale projects. Delayed project approvals and implementation. As a reaction to high-profile governance scandals, project approvals, clearances, and implementation have slowed sharply. Supply bottlenecks are particularly pronounced in mining and power, with attendant consequences for the broader economy, especially manufacturing.

The board of the National Agency of Electrical Energy (ANEEL) approved today (April 17th) rules to reduce barriers to the installation of distributed generation ofup to 100 KW of power (micro generation), and from 100 KW to 1 MW of power (mini generation).

It was reported that Hefei Risheng Science and Technology Co. signed a contract with Guang'an Economic and Technology Development Zone to construct a 30ktpy copper profile project in Guang'an, Sichuan province. The project, which also consists of a 100ktpy aluminium profile business, will cost 470 million yuan and is expected to generate revenues of 3.2 billion yuan and profits of 500 million yuan. In addition, the company will collaborate with Sichuan Dongyang Housing Development Co. to build 20 production lines of single crystal copper bond wire and 20 production lines of micro electromagnetic wire in Guang'an. Total investment will amount to 500 million yuan.
