Medium speed permanent magnet generators (MS PMGs) deliver more than 98% efficiency - the highest of any commercial wind generator design. Efficiency is also high at partial loads in low wind conditions, enabling the optimum annual production of kWh. This article spotlights the design and testing effort behind ABB’s multi-MW medium-speed and medium-voltage generator-converter package. [ + ]

Richgro is an Australian-owned family business that has been helping people tend their gardens since 1916. In mid-2009, Richgro drew up plans to install a major organic fertiliser plant on its site in Jandakot, Western Australia.

As discussed in the IDTechEx Research report ‘Organic Photovoltaics (OPV) 2013-2023: Technologies, Markets, Players’, organic photovoltaics, although potentially a disruptive technology, do not currently offer very high efficiency levels or lifetime and these characteristics limit their market uptake. On the other hand, OPVs can offer versatility in form factor, improved indoor performance and low capital expenditure for large-scale manufacture. In this article, Dr Harry Zervos, Senior Technology Analyst, IDTechEx, summarises some of the details of the report. [ + ]
