2. PERIDOT HOLDINGS Peridot Technology Photovoltaic General Overview
Uses CSP with to produce hot water under pressure, flashed to steam without a boiler to power a bladeless turbine to produce AC power.
Can use rolling hills without levelling prior to installation (lower land preparation costs)
Construction time is reduced versus other technologies
Photovoltaic
PV cells produce DC power – must use inverter to convert to AC.
Must use level ground for installation.
Capacity for production of PV cells is limited and expansion of capacity takes a long time.

3. PERIDOT HOLDINGS Peridot Technology Other CSP General Overview
Uses CSP with to produce hot water under pressure, flashed to steam without a boiler to power a bladeless turbine to produce AC power.
Can use rolling hills without levelling prior to installation (lower land preparation costs)
Construction time is reduced versus other technologies
Other CSP
Use mirrors to reflect sunlight to focal point for heat to make steam to power standard turbines.
Installation is tedious and focal point is difficult to maintain.
Limited life of mirrors and must clean often to maintain power production goals.

4. Tracking , Storage, Degradation
Peridot Technology
PERIDOT HOLDINGS
Tracking , Storage, Degradation PV
Standard fixed installation will produce less power
versus single or dual axis tracking of the sun.
Only batteries can be used with PV to store power.
These are expensive and have limited life (5-10 yrs.)
Well known degradation in capacity over some years
Peridot Technology
Supplied with dual axis tracking to produce 30%
more power versus fixed systems.
Can use efficient heat sinks (such as molten salt)
which are low cost and last a lifetime.
No degradation in capacity because lens does not
degrade as a PV cell does.

5. Maintenance, Operation, Replacement

Maintenance, Operation, Replacement PV
After years – virtually 100% of original cost to replace both panels and inverters.
High cost of maintenance increases operation costs.
Peridot Technology
After years – about 20% of original cost to replace lenses. Likely not needed until 60 years.
Very low maintenance and operation costs.

6. Well suited for on - site residential installations.

PERIDOT HOLDINGS
Efficiency PV
Well suited for on - site residential installations.
Does not utilize the sun’s heat – energy wasted
Peridot Technology
US DOE says solar thermal (not PV) is most reliable for utility scale power plants.
Heat remaining after electricity production can be used for many useful purposes (heat storage, water purification, manufacturing processes, etc.). Thus, Peridot CSP system is 3 times more efficient vs. PV.

7. Refracts sunlight – more easily focused
Peridot Technology
PERIDOT HOLDINGS
Lens, Mirrors
Peridot Technology:
Refracts sunlight – more easily focused
Flat surface lens does not need regular cleaning
Other CSP:
Reflects sunlight – 4 times more difficult to focus
Dust or dirt buildup on mirror requires regular cleaning

8. Refracts sunlight – receiver is behind lens not in front
Peridot Technology
PERIDOT HOLDINGS
Versus Areva
Peridot Technology:
Refracts sunlight – receiver is behind lens not in front
Flat surface lens does not need regular cleaning – no mirror
Comes with bladeless turbine for AC power generation
Areva:
Reflects sunlight to pipes in front of mirror(s) using Fresnel lens to concentrate sunlight.
Dust or dirt buildup on mirror requires regular cleaning
Lacking technology for power generation (only steam)

9. PERIDOT HOLDINGS Peridot Technology
Other CSP
Peridot Technology
With receiver behind the lens, easier, lower cost installation and much wider focal point
Uses hot water under pressure in pipes (not standard steam cycle) and bladeless turbine / generator for low cost operation (no need for boiler, dry steam, etc.)
Other CSP
With receiver pipes in front of the mirror, expensive installation and difficult focal point
Uses traditional steam cycle (boilers, superheaters, expansion tanks) to turn a bladed turbine and generator
