The Carruthers Waterwheel - International Water Power
Jan 19, 2021 · The first waterwheel to be patented in 138 years, Carruthers Wheel is truly innovative, producing electricity from waterfalls and rivers with less than five metres drop. This was previously deemed unviable and unprofitable because of the high cost of turbines for small bodies of water. The Carruthers Wheel ignores previous design assumptions ...

Concrete solutions: strengthening America’s dams
Oct 11, 2023 · S&T chose to work on this effort because water poses very challenging and complex situations for concrete. What works for aging water infrastructure like dams and levees, most likely would work for dry-land concrete-based infrastructure like bridges and buildings. This initial use case could become the catalyst for an entire research agenda.
Pumped storage: powering a sustainable future
Nov 21, 2023 · Pumped storage provides a ‘load’ when the wind is blowing and the sun is shining, and it also provides a reliable and immediate source of dispatchable energy when the available renewable generation can’t meet demand. By pumping the water uphill when generation exceeds demand, the pumped storage scheme is essentially ‘storing’ energy ...
Canada’s energy future is powered by water
Aug 31, 2022 · Water is the lifeforce of humanity. For over 130 years, water has powered Canada from coast to coast – providing clean, renewable, affordable and abundant power for business, homes, technology, electric vehicles, and more. Today there are over 550 hydropower facilities across the country, powering over 60 per cent of Canada’s electricity needs.
Safety management of dams – the Australian practice
Jun 3, 2021 · Dr Gamini Adikari and Natalie Kho of SMEC present details on dam safety practice and legislation in Australia. Dam safety guidelines and management programs provide the foresight needed to prevent the disastrous failure of dams. In Australia alone, there are over 500 large dams, with these dams being typically more than 15m high (refer Figure 1).
The infinite turbine - International Water Power
Aug 10, 1999 · The infinite turbine. By introducing variable pitched blades, Viktor Kaplan’s design made it possible for a single turbine to offer high efficiency over a range of loads, and 80 years after its debut, the Kaplan turbine still has attractive characteristics.

Sand dams: a sustainable solution for water scarce regions
Jun 4, 2014 · Sand dams. A Sand dam is typical concrete embankment or wall built across an ephemeral (seasonal) stream. During the rainy season, the wall harvest sand and 20-40% of its total volume is water. The water is then abstracted using various methods depending on the intended use by the communities.
