BIOENERGY RECOVERY APPARATUS Russian patent published in 2000 - IPC

FIELD: biotechnology, in particular, equipment for recovery of plant energy during vegetation. SUBSTANCE: apparatus has vegetative tubes of variable section mounted in spiral path on spherical surface in several stages one above the other for rotation and turning about central vertical axis. Variable section of vegetative tubes depends on volume of plant and extent of changing of the volume of plant during vegetation. Turning is effectuated by applying complex single-vector gravitational force of conveyor carrying plants, whose weight is increased as they grow as well as due to down motion, gravity of nutrient solution directed to plants oriented upward with their roots, growth of plants, osmosis processes, forces exerted by plants striving to light source positioned under plants, pressure of streams with gaseous mixture, as well as due to forces generated in the process of suction of plant rootage respiratory metabolites. Apparatus is further provided with energy accumulators and probes to which solar radiation concentrators are hung. Solar radiation concentrators are equipped with heat-receiving members and light-emitting diodes. EFFECT: increased efficiency in recovering plant energy, simplified plant growing process and increased plant yield. 3 cl, 16 dwg
