Abstract

Methods and associated apparatus for automatically growing agricultural crops vertically and/or in a continuous fashion throughout each year (Vertical Farm) in combination with contiguous and co-located production of biofuel, food, biomass for the purpose of carbon sequestering (carbon credits), and biomass electric power generation. A process that incorporates vast arrays of continuous-loop conveyors, towering upon vertical framework, which allow potted plants to be transported throughout all stages of maturity in a manner which substantially multiplies yield per acre, allows production to proceed in both natural and artificial light, allows production and harvesting to be automated, and allows production to proceed in conditions which are highly favorable to plants but unfavorable to humans. The entire apparatus can be constructed of lightweight, cost-effective materials which afford mass-production and mass-array into vast automatic growing operations.

Claims

1. A Combined Vertical Farm, Biofuel, Biomass, and Electric Power Generation Process and Facility in a closed system, which incorporates the automated production of biomass and food that can be optimally transformed into biofuel and electricity as desired, which is comprised of:

a. The process flow beginning with the production of plants in vast arrays of continuous conveyance loops.

b. Optimized vertical conveyance loops of potted plants.

c. Optimize vertical conveyance loops which transport plants in the closest possible proximity to one another

d. Optimize vertical conveyance loops which approximate the same planar distribution of plants normally associated with the unit ground space while gaining a multiplicative advantage in productivity as a result of multiple tiers of plants circulating from the ground up and back down vertical towers.

e. Optimize vertical conveyance loops which can index at regular intervals such as each minute, hour, day, week, or month depending on the particular species'"'"' growth versus time, the number of total plants in the tower, the height of the tower, and the rate at which the conveyance loops are indexed.

f. A vertical growing apparatus, or “

Modular Vertical Farm Cell”

(MVFC) that has been fully described in a separate patent application by the same author of this invention.

2. A Modular Vertical Farm Cell or continuous-loop conveyor as claimed in claim 1 wherein said frame transports pots for plants which incorporate a guide or guides which gather and fix the positions of optimal holding and cutting areas for said plants. Said holding and cutting areas are thereby facilitated for automated holding, harvesting, and picking.

3. A Modular Vertical Farm Cell or continuous-loop conveyor as claimed in claim 1 comprised to facilitate optimal plant breeding by fixing the positions of said plants at all stages of maturity, thereby allowing said plants to be automatically measured and compared. Further said fixing of individual positions allows automated determinations to take place as to which plants exhibit the best genetic characteristics and the subsequent automatic and preferential selection of said optimal individuals for subsequent breeding and planting.

4. A Modular Vertical Farm Cell or continuous-loop conveyor as claimed in claim 1 comprised to allow automatic operation such that the entire apparatus can be placed in conditions such as a controlled environment enclosure or greenhouse the conditions of which might be ideal for said plants but which humans cannot withstand such as but not limited to elevated carbon-dioxide, depleted oxygen, enhanced lighting in excess of natural sunlight, elevated temperatures, elevated humidity, dispersions of deliberately chosen pollutants, and the additions of favorable chemicals for fertilization, anti-microbial, and herbicidal purposes.

5. A Modular Vertical Farm Cell or continuous-loop conveyor as claimed in claim 1 comprised to allow automatic operation in order to achieve the fastest possible conveyance from harvest to use and thereby retain the freshest characteristics at the point-of-use.

6. A Modular Vertical Farm Cell or continuous-loop conveyor as claimed in claim 1 which effectively multiplies the quantity of plants cultivated per unit land-area by creating an array of plants on said framework which towers in vertical columns.

7. The system of claim 6 which allows a mass-arrayed farm comprised of said Modular Vertical Farm Cells or continuous-loop conveyors as claimed in claim 1 to be arranged in close proximity to apparatus such as power generation facilities, distillation facilities, milling operations, and other processing facilities in order to benefit from sources of waste heat, waste carbon dioxide, waste steam, waste water, and excess power.

8. The system of claim 6 which allows the growing day and growing season for said plants to be extended or multiplied.

9. The system of claim 1 which allows the adaptation of the design to any perennial crop or other crops.

10. The system of claim 1 which allows just-in-time harvesting of said plants.

11. The system of claim 1 which allows the entire apparatus to be constructed at a low enough cost to be mass-produced and mass-arrayed into an extensive farming operation.

12. A system of cultivation where crops may be harvested automatically which is comprised of:

a. Cultivation of crops in vast arrays of MVFC'"'"'s or indexing vertical growing apparatuses where the plants are harvested at fixed locations by conventional industrial robots.

b. Movement of the robots from MVFC to MVFC on automated rail or cable-guided trolleys for sequential harvesting of each MVFC.

c. Transportation of harvested foods and biomass on networks of conveyors to a central location for milling, fermentation, and distillation into biofuels.

13. A system of processing waste products from in-situ farming, milling, fermentation, and distillation, comprised generally of leftover biomass including:

a. Reforming into more biofuel.

b. Burning in a Rankine power cycle to produce electricity

c. Burial or conversion to durable consumer goods to the end of sequestering carbon from the atmosphere and the accompanying end of reversing or controlling global warming.

d. Burial for the purposes of providing high-quality topsoil and landfill.

e. Processing for exploitation of other by products.

14. A system of processing the waste products of the combustion processes (reforming, electric generation) comprised generally of heat, moisture, carbon dioxide, mineral ash, and reactive nitrogen by recycling these back to the Vertical Farm. The compact nature of the Vertical Farming operation allows even distribution of these waste products, with minimal losses.

15. A fully automated and enclosed process which can be operated in conditions inhospitable to human occupancy and yet remarkably optimal for the cultivation of plants that has the following advantages:

a. Greatly enhanced growing characteristics as a result of elevated carbon dioxide.

b. Enhanced growing characteristics as a result of decreased oxygen.

c. Enhanced growing characteristics as a result supplemental light.

d. Enhanced growing characteristics as a result extended growing day.

e. A conveyor configuration in which individual plants are moved a zigzag fashion through the course of ascending and descending helical traverses upon the framework for which the pitch of and vertical spacing between traverses are constructed in a manner which follows the normal growth curve and affords ideal accessibility at the point of optimal harvest.

f. A conveyor configuration in which potted seeds, seed-pieces, seedlings, or freshly clipped perennial root masses start on the framework at the beginning of a lower, horizontal traverse, at a point of ideal accessibility. Freshly initiated plants travel across the lower, horizontal traverse, where they ascend the conveyance along the reversing traverses and helical path of a vertical column on the framework as they mature into adolescent plants. The adolescent plants cross over along an upper, horizontal traverse on the framework to another column on the framework, where they descend the conveyance along the reversing traverses and helical path of said second column until they reach finalize maturation at the starting position, where they are harvested. The freshly cut plants are then replaced if aged or recycled through the same path described if said plants continue to be vital after harvest.

17. The system of claim 16 where said plants arranged with optimum density by spacing of conveyor traverses such that the size of plants at each stage of maturity is most precisely afforded.

18. The system of claim 16 where said plants, while optimally spaced to minimize overall space are yet spaced such that natural and artificial light sources filter throughout the conveyance and such that statistical variations in plant size are afforded by extra space allowance.
