Save massive energy finally with straighter larger tubing in municipal systems

Here's the short version: 

• About half of the world's electricity runs electric motors, and half of that motor torque drives fans and pumps.

• Friction Reduction: Narrow, twisting pipes create massive fluid friction. Straight, wide-diameter pipes cut friction by 86% or more.

• Downsized Equipment: When friction drops, the pumps and motors pushing the fluid can be shrunk significantly (often by 80–90%).

• Lower Costs: Redesigning the whole loop frequently lowers total capital costs (because smaller pumps and motors cost less) while paying for itself in under a year or instantaneously on new builds.
