The Archimedes' Principle Using a hydropower screw for electricity production signals a conversion in the use of energy by the Archimedean screw. In the ancient world, the invention was used to irrigate the fields with water from the Nile.
HYDROPOWER SCREW FACT No. 2
Hydropower screws are environmentally friendly. Hydropower screws used in conjunction with a generator are an environmentally friendly component of the regional, decentralised and cost-saving energy transition policy.
HYDROPOWER SCREW FACT No. 3
Hydropower screws are economical. The screw has a mechanical efficiency of up to 90%. It's effectiveness is also only slightly affected by varying water levels.
HYDROPOWER SCREW FACT No. 4
Hydropower screws can be used for decentralised power generation. A hydropower plant allows you to take the Federal Government's energy transition policy into your own hands and cover your own needs with clean electricity. And the needs of "umpteen" neighbours. Or you can feed this clean energy into the grid.v
HYDROPOWER SCREW FACT No. 5
Conventionally generated energy is constantly becoming more expensive. Every rise in costs boosts the financial viability of using renewable energy sources. Hydropower represents the most economical energy source, since it does not consume resources and it operates at the highest level of efficiency. These systems remain economical even if state subsidies are cut.
HYDROPOWER SCREW FACT No. 6
Small hydropower does not produce any particulate emissions. Unlike the combustion of wood, for example, hydropower screws operate without causing any damage to the next generation. They also work with minimal disruption to fish and other water fauna.
HYDROPOWER SCREW FACT No. 7
Hydropower plants operate with virtually no personnel. Their fully automatic operation allows you to generate electricity without supervision. Winter operation is also generally trouble free.
HYDROPOWER SCREW FACT No. 8
Hydropower plants can serve as flood protection. Hydropower screws can also be constructed as water lifting screws and thus serve as flood control and for draining flooded areas.
HYDROPOWER SCREW FACT No. 9
Our systems blend unobtrusively into the surrounding area. The surface of our hydropower screws can be landscaped. Only the tube and the small machine base for the generator remain visible.
HYDROPOWER SCREW FACT No. 10
Hydropower plants are quiet. The slow motion and reduced noise emission outlet reduction also make hydropower screws suitable for sites located near residential areas.
HYDROPOWER SCREW FACT No. 11
Hydropower screws also function with low heads of water. In contrast to turbine systems, hydropower plants with screw-based systems can be used where there is a head of only one metre.
HYDROPOWER SCREW FACT No. 12
The systems require only a coarse grate. Normal debris passes freely through both the grate and the screw. This helps retain the natural sediment structure of the watercourse.
HYDROPOWER SCREW FACT No. 13
The technology works well with nature. Modernising existing weir systems with an Archimedean screw significantly improves their ecological balance.
HYDROPOWER SCREW FACT No. 14
The plants are robust and durable. Even with intensive use, these screws often run for 35 or 40 years without significant restrictions.
HYDROPOWER SCREW FACT No. 15
Small hydro power screws permanently generate energy. They continue to run at night and on windless days, when the water level is low and also in the event of a flood or when there is snow and ice. A year comprises 8,760 hours. A hydropower plant runs for approximately 6,000 hours of these, while a photovoltaic system is in operation for only about 3,000 hours.
HYDROPOWER SCREW FACT No. 16
Electricity generated from hydropower is good for the carbon footprint. In Europe, about 13 million households are supplied with electricity from small hydro power. This saves 29 million tonnes of CO2. The CO2 savings made by small hydropower in Europe alone equate to 10,000 small cars travelling around the world 820 times.
