  • Using thermal storage to enable the system to run 24/7
  • Low “total cost/kW generated” parameter
  • Minimal maintenance
  • Zero leak on hydraulic and fluid loops
  • Easy to fabricate, easy to assembly on site
  • Environmentally friendly
  • Self-diagnosing system
  • “Off the grid” power concept
  • On site power generation, Where power grids do not exist

 

System Description in Summary

A set of uniquely designed panels absorb solar heat and transfer it to a thermal storage unit. The system is based on two closed loop streams. One stream comprises either hot or cold water loops and the other employs a special fluid with very high thermal expansion coefficient, using a CVMR® manufactured special nano metal powder made specifically for this purpose.

A hydraulic rectifier is employed to convert these two oscillatory motions into a continuous motion. A hydraulic motor propels a power generator at 900 rpm.
