Policy makers, economists and water researchers have advocated water transfer and trade as a key potential response to worldwide water scarcity and/or efficiency problems. This paper examines aspects of an operational irrigation scheme in New Zealand that enables transfer of water between...

To improve knowledge of the wind loads on photovoltaic structures mounted on flat roofs at the high angles required in high latitudes, and to study starting flow on low aspect ratio wind turbine blades, a series of wind tunnel tests were undertaken. Thin flat plates of aspect ratios between 0.4...

This article examines how public policy can and does play a role in enabling impact investing by U.S. institutional asset owners. We outline how government often plays a key role as underwriter, co-investor, regulator, procurer of goods and services, or provider of subsidies and technical...

During the last decade, Latin American countries have brought about important reforms in infrastructure services based both on private sector participation for enhancing internal efficiency and competition for increasing consumer welfare. Infrastructure services have evolved from monopoly and...

A major barrier to the acceptance of small wind turbines is that they are perceived to be noisy. This paper investigates an aspect of noise emission that has not been considered; vibration and noise generation from the tower. First, vibration measurements were made using accelerometers placed on...
