The methodology has been applied to the design of positive feedback adiabatic logic (PFAL) carry look-ahead adders (CLA).
Post-layout simulations of the standard- cell PFAL Class show a 94% energy recovery as compared to a conventional static CMOSCLA at 10MHz, and 86% at 100MHz.
The power analyse is report shows the minimum power consumption, maximum power consumption and average power consumption for conventional PFAL full adder circuits

* Universal PFAL design to ensure system safety, accessibility for the aged and physically challenged, and good design in all aspects.
Water consumption for irrigation in PFALs is reduced by about 95 percent compared to open-field production by recycling the water transpired by leaves, using the air conditioning system as a condenser.
Plants that are most suitable for commercial production in PFALs are those that grow well at relatively low light intensity and at high planting density, and that are mostly edible (leaves, stems, and roots) or salable at a high price.
Currently, most leaf vegetables and herbs produced in PFALs are not sold at supermarkets or grocery stores.
In addition to the above, Kozai's study throws light on the essential benefits of PFAL as well.
Currently, compared to the greenhouse, the PFAL can save water consumption for irrigation per kg of produce by 95% by recycling use of transpired water vapor from plants (The transpired water vapor is condensed and collected at the cooling coil of air conditioners and returned to nutrient solution tank).
Kozai's excellent research suggests how the CP can be more than doubled and the impact and the expected increase this will have on the PFAL market.
Further, Kozai has discussed the idea of next-generation PFAL (n-PFAL) and the associated requirements, scheme for R&D, challenges and opportunities.
