e-Giver
Gift of the river
Get a gift of energy from a river stream - print your little water turbine on your 3D printer!
Have you ever wondered how beneficial it would be to use the energy of a river or stream that flows under your house or a cottage? Or are you an avid fisherman and charging your mobile or power bank during your weekend stay by the river would be a great bonus? In addition, if you are a fan of 3D printing and alternative energy sources are your hobby, then you are in the right place!
Small water turbines e-Giver
The power range of the small e-Giver turbines is designed as a horizontal version of the Kaplan turbine, which uses the kinetic energy of the stream flow. The performance of the turbine is directly dependent on the speed of the water flow.
The range includes two sizes of turbines - e-Giver 10 with a nominal power of 5W and e-Giver 50 with a power of 15W. The e-Giver 10 is designed to be printed by a small desktop 3D printer with a print space of at least 210x250x210 mm, such as the Original PRUSA i3 MK3S + and similarly, the e-Giver 50 requires a printer with a minimum space of 360x360x360 mm, such as the Original PRUSA XL.

"We were pleased to accept an offer for the design and construction of a range of small e-Giver water turbines. This product has expanded our portfolio of design projects and brought new experiences with the application of 3D printing technologies."

Project founder
"I perceive the use of small turbines of this type as a way of sensitive use of natural energy of small watercourses.
The 24/7 stability of this source also makes sense for smaller, but permanently available, turbine power parameters".
