Swimergy and the Riptide Tether
Generating a smooth, powerful current takes energy and that means electrical bills. The Swimergy system uses an elastic Riptide tether that attaches to special swimmers shoes. This provides the resistance to swimming with no ongoing costs.
Many college swim teams use this kind of resistance system and the Special Forces Scuba Team at Fort Bragg have a similar set up for endurance training.
The main problem with this kind of approach is the waves and turbulence created by the swimmer. Swimergy have a specially designed pool that reduces turbulence to a minimum.
So if you want swimming exercise with a minimum outlay and low running costs this could be the best system for you.
The simplicity of the Swimergy system means a lot of floor space in the pool. Many swim spas have so much equipment behind the bulges and 'benches' of their molded walls, the floor space and swim area is very restricted.
In the Swimergy there is plenty of room for two people to swim in place and, alternatively, it can accommodate a lot of kids who just want to splash around.
Overall size: 8'x 15' x 48"

Still water swimming in a pool designed to suppress turbulence from Swimergy.
The floor space can accommodate aquatic exercise machinery like treadmills but a still water pool, obviously, does not offer running against a current.
The Swimergy has a very clear description of the pluses and minuses of its system and a detailed breakdown of costs.
