Definitions
- Our novel invention makes use of the biomimicry concept it allows us to combine form and function into one concept. This approach will not only produce cool new products, it also could eventually result in processes that are more energy efficient, reduce our carbon footprint, and help to deliver green clean electricity in aesthetic way.
- Green biomimicry energy harvesting systems can bring renewable energy closer to the end user, it broadens the application range of green renewable energy products, instead occupying more land we can install artificial trees on streets, along highways and railways, but also along coastal areas, islands, remote areas or places of natural beauty.
- Solar Botanic's is to realize the natural representation of green energy harvesting by artificial trees in real landscapes and urban areas to create eco-friendly and sustainable energy systems that fit any environment.
- the invention will describe a method of incorporating thermo - photovoltaic and piezoelectric materials into an artificial leaf design.
- the main goal of this approach is to mimic the simulation and visualization of natural growth and to harvest and capture renewable energies from the environment.
- Nanoleaves collective name for artificial leaves and needles
- These Nanoleaves get affixed to artificial trees, shrubs or plant structures, or can be affixed to carpet matrixes, green energy carpets can installed on roofs or walls to generated electricity, give a real green ambiance, another important thing is the installation time of energy roof carpet, which would only take a couple of minutes.
- the green energy carpets can be constructed is such a manor that these would float, therefore these floating energy carpets with a variety of Nanoleaves including kelp could easily be set out on the ocean(s) to convert wave motion, and solar radiation into clean electricity.
- thermo- photovoltaic Nanoleaves the most fundamental issue in assessing thermo- photovoltaic Nanoleaves is efficiency — how much of the solar radiation that falls on the artificial Nanoleaf can it convert to electricity? How much of the wind energy, rain energy and hail energy can it convert to electricity?
- leaves all with different properties therefore we can account for all leaves, no matter what size, however, small leaves little movement, big leaves more movement, and thus more energy' less dense canopies less solar energy capture, dense canopies more solar energy capture, thus more energy, from better understanding and designing.
- most poplars and phoenix trees had such kind of leaves. Both of these kinds of leaves are consist of a long leafstalk and a large leaf surface, it makes leaves move easier even under gentle breeze. This is because: due to fluid or flow mechanics, the larger leaf surface area, the stronger force will be loaded on the leaf by wind; due to solid mechanics, the longer the leafstalk, the more flexible of the whole leaf structure.
- the PCE in the leaf nerve, petiole, twig or branch is compressed and elongated.
- electrical charges appear on the surface and are collected by the electrodes.
- the generated alternative electrical signal is sent to an electrical load or to an Energy Harvesting Circuit.
- One of the goals of the energy biomimicry invention is to utilize and demonstrate piezo electric power generation from wind using piezo electric materials and piezoelectric connecting elements. Mechanical vibrations or motions from wind or surrounding (like building, machines, human body).
- the piezo electric generators will be incorporated into the artificial leaf nerve (that also is carrying the leaf), petiole, twigs, and branches and in some cases we incorporate piezoelectric materials in the main stem or trunk of the artificial tree or plant, so that it will produce electrical power (in the range of ⁇ W) and which will unite with other electric currents coming from thermophotovoltaic activity, all of which can be used to feed an battery system, electrical grid or other appointed use.
- the compressive and tension resistances in petiole or stalk immediately initiate a reverse motion. In an ideal situation, this reverse (toward the direction of the applied force) movement would be exactly opposite in direction.
- piezoelectric materials begin generation of electricity within a tree/plant stem and petiole as a result of movement, tension and compression resistances as force applied, a piezoelectric effect converts mechanical strain into ionic polarization charges that generate a piezoelectric potential that we can collect.
- Loads on trees are repeatedly stretching and releasing a single Nano piezoelectric wire with a strain of 0.05-0.1% creates an oscillating output voltage of up to _50 mV, and the energy conversion efficiency of the wire can be as high as 6.8%. We even will generate energy from rain showers and convert it into electricity.
- e mv 2 /2.
- piezoelectric materials are already widely used to convert mechanical energy into electrical energy, and have lately been applied to various environmental energy scavenging scenarios: for example, in one system, a piezoelectric material is installed on windmills to recover wind energy; the Eel concept uses the deformation of a Polyvinylidene Fluoride (PVDF) membrane subjected to a tangential flow, and yet another system involves mounting a PZT (Piezoelectric Transducer) disc to a Helmholtz resonator to harvest acoustic energy.
- PVDF Polyvinylidene Fluoride
- PZT piezoelectric Transducer
- the Piezoelectric Connecting Elements is very versatile and easy to install, we can insert it into the petiole/stalk to attach the nanoleaf and next we can insert the nanoleaf into the stem, twig or branch and is all weather type secured via its improved 'cable tie" connection which is still very flexible this enables the PCE to harvest and captured kinetic energy as the nanoleaf starts to move and bend due to wind or vibrate/tremble as rain drops impacts the surface.
- the PCL can be mass produced, and will fit a variety of different leaf types and sizes and it is easy and quick to work with.
- the assembly of complete branches with full foliage can be done in minutes.
- the leaf petiole/stalk is hollow, into which we can insert the PCL;
- These "Un- releasable" Piezoelectric connecting elements are perfect to permanently secure the Nanoleaf to the stem, twig or branch.
- the PCE is made of a synthetic material in which piezoelectric material is spiralled along its length and covered by a protective layer.
- the outer layer is made of strong, tensile, acid and corrosion resistant and durable material, for example nylon, it can be designed as circular or flat depending on it use, although piezoelectric connecting elements are generally used as single-use devices, if a tied leaf needs to be released again, then, rather than destroying the PCE by cutting, it may be possible to release the PCE from the leaf to reuse the PCE again.
- Each PCE tie has a tapered tip to ensure simple and quick installation.
- the PCE can be connected and secured to the petiole/leafstalk (carrying the leave), the remaining part of the PCE we insert into the opening of the twig or stem that has the receiving connecting point, and we can push the leaf until the end/final position, which will "permanently” secure it.
- Nanoleaves can be easily assembled by hand and remain locked until intentionally released by the finger catch. They can be used in a variety of applications
- petiole or stalk that what runs from the leaf tip to the end of the petiole/stalk including its mid-ribs has a function to hold and secure the Nanoleaf (the surface that is photo/thermovoltaic) to the central leaf nerve or vain
- the main leaf nerve/vain including its mid-rib segments that holds the leaf and ensures stability for the leaf is designed with small protrusions onto which the photo-thermovoltaic flexible sheet with pre-designed pores can be pressed, this one way press system securely attaches the flexible solar sheet to the main leaf nerve/vain and its mid-ribs, it locks tightly and gives maximum support and leaf surface stability.
- the nanoleaf might consist of two different substances, such as shinny reflecting (or non reflecting - perhaps even glossy) solar (nano) photovoltaic material, or a Nanoantenna material that collects sunlight, and reflects it, and furthermore comprises a feature that collects heat and converts it into electricity but as well reflects heat to different Nanoleaves in different layers within the tree canopy or plant canopy.
- shinny reflecting (or non reflecting - perhaps even glossy) solar (nano) photovoltaic material or a Nanoantenna material that collects sunlight, and reflects it, and furthermore comprises a feature that collects heat and converts it into electricity but as well reflects heat to different Nanoleaves in different layers within the tree canopy or plant canopy.
- Reflection occurs, as in a mirror, when a sun ray encounters the boundary but does not pass into the second medium, instead immediately changing course and returning to the original medium, typically reflecting from the surface at the same angle at which it contacted it.
- Refraction occurs, as in a lens, when a sun ray passes from one medium into the second, deviating from the straight path it otherwise would have taken. The amount of deviation or "bending" depends on the indexes of refraction of each medium, determined by the relative speed sunlight in the two media. Sun rays entering a medium with a higher index of refraction are slowed, leaving the Nanoleaf surface and entering the second, third, fourth etc. at a greater angle than the incident sun ray.
- the present invention is directed to the biomimicry concept, looking at nature in new ways to fully appreciate and understand how it can be used to help solve problems, in this case the construction of artificial leaves and needles.
- Nature as model means emulating nature's forms, processes and systems to solve human problems; this is the act of biomimicry.
- Nature as measure means evaluating our designs and solutions against those of nature. This involves asking if our current methods are as efficient, simple and sustainable as those found in nature.
- the present invention is directed to not only an improved method and construction for affixing leaves and/or other branches and limbs in an aesthetically pleasing and authentically appearing fashion but to exploit stress loads in petiole/leaf stalk with the incorporation of piezo electric materials at these stress locations.

- bio-based polymers we intend to use produce robust bio-based components that meet the stringent thermal and durability requirements of current solar cell manufacturing processes.
- These materials can be used directly in conventional manufacturing systems, such as injection molding and thin-film roll- to-roll, to create superstrate layer, substrate layer, and backsheet and as well as module and panel components.
- this material can help reduce the cost per watt through the use of its lower cost bio-based materials.
- Nanoleaves made from bio-based materials make use of the latest photo and thermovoltaic materials; new thinfilm process allows us to make use of bio- based flexible thinfilm on both sides, deposition of thinfilm cells in leaf shape form, new method for attaching a nanoleaf to a twig or branch via the piezoelectric connecting elements, and a new way to connect a photo-thermovoltaic film to a leaf carrier say leaf nerve including rib segments.
- Plant and trees are complex structures, but their geometry is known to obey simple laws: diameters and length of segments are well organized from trunk to small branches including the complex sway motion and various directions of leaves and limbs.
- diameters and length of segments are well organized from trunk to small branches including the complex sway motion and various directions of leaves and limbs.
- the connective means in fig 4 shows a piezoelectric connecting element that is simply driven into the petiole and the other side into the twig, stem or branch, a permanent fit.
- the present invention was achieved in order to solve the aforementioned problems and is aimed at providing a green solar/wind power collecting structure which can effectively be used in areas that are restricted or that have commercial value, like private home gardens, recreation areas, nature resorts, urban areas, non productive areas within industrial sites, mountains and hill areas, coastlines, deserts, oceans, military, lakes: all for the purpose of generating solar energy.

Abstract
Récupérer de l'énergie à partir de l'environnement de façon responsable est important, et c'est ce que font, de façon efficace, les arbres et les plantes naturels depuis des millions d'années. La présente invention concerne l'imitation de cet ingénieux concept, cela étant également connu sous le nom de biomimétisme ou de biomimétique. La présente invention concerne, en particulier, des feuilles et des aiguilles intégrant des nanomatériaux permettant à la nanofeuille de récupérer, de capturer, dans l'environnement, de l'énergie, comme le rayonnement solaire, le vent et le bruit, pour la transformer en électricité, lesdites nanofeuilles étant constituées d'un support souple, exploité sur les deux faces et faisant appel à un procédé connu sous le nom de dépôt en couche mince qui va permettre l'incorporation de matériaux thermophotovoltaïques utilisables à des fins de conversion du rayonnement solaire (lumière et chaleur). Nous avons, en outre, introduit des éléments de connexion piézoélectriques qui connectent/relient la feuille à la plante ou à l'arbre, ce qui permet non seulement un montage rapide et sûr, mais ce qui permet également de transformer l'énergie éolienne en électricité. De plus, nous avons l'intention de rendre nos nanofeuilles aussi proches de la réalité que possible, l'une des façons d'obtenir cela étant de gaufrer les feuilles, de créer une image de la surface de la feuille en trois dimensions, ce qui se révèle avantageux pour récupérer et capturer le rayonnement solaire. L'invention constitue une avancée par rapport aux feuilles, aiguilles et herbes artificielles, dont les plantes aquatiques, de l'état de la technique, puisqu'elle permet non seulement d'envisager une façon efficace et économique de récupérer le rayonnement solaire et l'énergie éolienne grâce à l'incorporation de matériaux thermophotovoltaïques et piézoélectriques, mais aussi puisqu'elle décrit un procédé permettant de fixer des feuilles artificielles capables de récupérer et de capturer le rayonnement solaire, l'énergie éolienne et l'énergie générée par les chutes de pluie et de grêle, lesdites feuilles et aiguilles artificielles à l'esthétique agréable et à l'air naturel pouvant être fixées sur des arbres, des plantes, des buissons et des plantes aquatiques.
