Abstract: The present invention relates to systems and methods for producing disease and pest control agent for plants and crops containing dissolved oxygen and ozone. This present invention of disease and pest control agent for plants and crops containing dissolved microbubbles of oxygen and ozone consists of 0.3-40 ?m pore size microbubbles of ozone (03) 1.0-10.0 volume % and oxygen (O2) 99.0-90.0 volume % dissolved in water as colloids and the concentration of ozone in this solution is 1˜30 mg/l. This invention produces disease and pest control agent for plants and crops that contains microbubbles consisting of highly concentrated oxygen and ozone dissolved in water as colloid which is environmentally friendly and highly effective as pesticidal and germicidal agent.

Abstract: A heat/electric supply system the entire efficiency of which is enhanced while reducing the capacity of facility. The heat/electric supply system is characterized in that electric power is supplied from a generator, a commercial power supply and a power storage unit in the time zone when power consumption by the power load is higher than a specified output C1 and commercial power is stored in a power storage unit in the night time zone can be utilized at the time of peak power demand, the backup power at the time of peak power demand can be reduced.
