Servos a step closer to 'building brick' motion control systems
A long-standing engineers' dream is to be able to assemble sophisticated, high-function, multi-axis servo systems from a kit of parts as easily as clicking a child's building bricks together. Gerard Bush of INMOCO says reality hasn't quite caught up with fantasy — but it is moving in the right direction

Cool air distribution key to managing datacentre energy costs
A perennial issue in the management of datacentres is finding efficient solutions for keeping the equipment cooled to within its operating temperatures. In all but the coldest of countries, ambient air temperature is too high to provide adequate cooling, meaning that Computer Room Air Conditioning (CRAC) is required, says Peter Lishman of of electronics enclosures company Retex

Reaping the benefits of energy harvesting
Energy harvesting is a rapidly growing industry. It is estimated that energy harvesting components will exceed $4 billion by 2020 — which is significant considering that the market was $79.5m in 2009, resulting in an average annual growth rate of over 73 per cent. Greg Quirk of Mouser Electronics looks at the benefits

Dealing with the barriers to tidal energy
The cost of energy generated by tidal power generation is, at this stage of device development, still more expensive than offshore and onshore wind and solar arrays. But, says Altra Industrial Motion, fossil fuels will not last forever — and the barrier to tidal energy is not a mechanical one. Anthony George, from Altra's Heavy Duty Clutch and Brake Division, explains
