Solar ovens provide a power-free cooking choice. Limited to midday (sunshine) hours, you can extend cooking time by putting in solar thermal heat absorbers, such as lava rock, dark colored bricks, or a new innovative technology called Zeolite pellets. Pellets are heated, and then when water is applied, the heat is released (water boils). Harvesting plants for food daily does not require the use of refrigeration.

Swiss Paddle Wheel
Renewable energy powered prime mover
Traditional screw propeller propulsion has been around for more than one hundred years. In it various forms, it has been proven to be reliable, and has morphed into the most modern evolution of electric pods (tractor and tug). Personal watercraft slow speed options include very efficient fins. All have the inherent issues of grounding, and line fouling. Providing planing hull propulsion requires a great deal of horsepower, while foiling devices require clean water due to fouling.Overall Constraints: Multiple power drive options. Reliability. Resistant to underwater hazards (grounding, line fouling). Repairability. Low maintenance. Ease of access. Sub-planing speeds for sustainable fuel efficient power (less than 15 knots).Final Choice: Look forward by looking back. Recent trips to Switzerland have shown paddlewheels are still being used, to great effect. While maybe not the most efficient option, they are extremely reliable, and great for overall propulsion. Relatively maintenance free, they are less prone to grounding issues, and easy to fix. This is our option for propulsion. Using a top mounted magnetic gear powered wash-down stainless steel motor, you can run at most efficient RPM while adjusting blade depth and profile (angle of attack). You can even attach a wind turbine axis output to direct drive the paddle wheel from the top diameter of the unit.Design Characteristics:Electric Drive: An electric drive option gives the user the option of multiple ways to produce power, including fuel engine, wind, thermal, and solar electric.Using AC Motor with DC: While contradictory to common knowledge, a AC motor can run on DC. The advantages of a AC motor are longer running life, and less acquisition cost. On smaller AC motors in commercial appliances, you’ll need to replace the switch, which will burn out quickly. This gives two options.Multiple Paddlewheel Drives: The paddlewheel drive mechanism will be mounted forward inboard of each outboard hull. This gives a tug-oriented pull format, with independent reversible propulsion that can act as bow thrusters for maneuvering during docking and anchor. A third paddle wheel will be mounted center hull aft for long range drive. Functionality: Each drive will have a vertical raising and lowering track for paddlewheel maintenance or lifting from the water. Underway, the vertical axis movement can be used to increase waterplane and more bite (thrust). Blades are flow engineered and tested for fluid dynamics and optimized for depth.Summary: There are multiple legacy options for marine propulsion. While screws have dominated the past 100 years, the most reliable and consistent drive is the paddlewheel. Using higher RPM electric motors with a magnetic gearbox to a lower RPM wheel will provide the best option for durability and less maintenance. Three drives not only provides redundancy, but also provides highly maneuverable directional control.
Goal: Develop a low cost, easy-to-build, modular multi-hull, that is efficient with a low water plane, low induced drag, lightweight, and can utilize standard formats for low cost outfittingOrganize: Use Filemaker (both computer and iPhone version) to establish data points, plans, supplies, parts, and deployment. That keeps the project organized, and allows you to keep track of flow and identify choke points. Keep a daily log of what gets done, including how goals are being completed, and upcoming strategy. Organizing thoughts streamlines the process, and allows feedback to improve the build. Watch and learn. Review YouTube videos on products and procedures (everything from unboxing to how to glass carbon fiber). The resources available to you prior purchase, or using your valuable time are now available on YouTube for free.Examples:- Standard house grade fuse boxes (tempered for marine environment)- Standard bathoom shower, tub, fixtures (reduce cost)- Standard 2 x 4 ft and 4 x 8 ft plywood (no or low cuts to square off)- Cart mounted modules for kitchen, bedroom, bathroom, workshop, powerDeploy:- Power Cart Station (first item to start since you need power to build) Roll aboard so you can use prior build, during, and after.

All infrastructure and power is high above water level. There is no power or wiring near the water.- Positive Floatation Hull Modular Platform: Won't sink. No bilge issues (and parasitic loads from removing water). Easier to maintain, no seacocks or through hull fittings. Strategy is to move everything above waterline.- Power Strategy: Power Pacs (Power Cart Station). Multiple modular cart mounted solutions for areas of the boat, instead of one central location. Redundancy. Mobile. Substitutable. Upgradable. Keeping PCS smaller allows easy integration, upgrading, and innovation. Might be more expensive initially, but over time, provides a better solution.Details:1. Overall Concept: Strategy, objective, goals, and delivery.Cost effective trimaran. Emphasis is on modular, low cost, high performance, renewable energy, lightweight utilitarian cruising and workboat. The modular aspects allow a quick-change mission reconfiguration. Since parts are modular, components are interchangeable. Unlike traditional boats, the basic structure and layout can be easily customized. Habitat pods will have independent power and lighting, which don’t make them dependent on one house battery system.2. Hull and Structure Design.The trimaran design is configured for low weight, solid (unsinkable) hulls, and wave piercing design. The long thin hulls do not require large amounts of power to move through the water. The hulls are continuous form molded with rolled bubblepack, reinforced with fiber mesh, and can also be integrated with liquid storage, and even configured with materials to make them into a supercapacitor or battery. Hulls are connected by cross members that can be affixed by bolts, lashing fiber, or other mechanical means. Standard hull segment is 2 feet in diameter with a 2 x 4 foot fiber core end plate, all carbon fiber wrapped and vacuum bag expoxied. Segments are attached by epoxy and bolts (permanent), or just bolted together. An outside skin may be applied for appearance, and painted to desired color and design. The main command and habitat is forward, similar to a workboat, but this structure can be forward or aft, depending on mission. Crossmembers connect hulls together and standard composite boards make up the full width decking.Dockboxes, habitat cabins, containers, and other semi-permanent structures may be affixed to composite decking directly. Forward center hull is the anchor station. Stainless steel lifelines are affixed on the perimeter, where a structure is not blocking exit from deck.Any electrical or water delivery conduit is ported above in PVC or sealtite tubing (above waterline).Hull is constructed of modular segments, comprised of roll-formed bubblepack with interlaced electrical storage material/electrolyte, epoxy and reinforcing structure, which is produced on a continuous form weaving/mould machine.3.

Build Production.Objective: The overall goal of the ama or hull build, is to automate floatation fabrication as much as possible, and provide a modular section that is easily attached to assemble/fabricate into one larger hull. Traditional hull construction is material over frame, or laying material into a mold in multiple layers that are vacuum bagged. Mould construction is time-consuming and costly, provides an expensive hull, and must have a large number of production units to recover cost. It is also labor-hour intensive. Hull structures tend to be overbuilt, heavy, and more materials equals more cost to the final customer. The goal of the overall project is to separate the hulls, to make them mission specific (i.e. provide flotation and in some cases act as liquid storage or energy storage).The concept of a continuous weaving mold (CWM) incorporates strength bearing materials (as-needed) and specific for the hull. Spools of material feed a loom, which is computer controlled for twist, feed rate, feed material, etc. What is unique about this CWM is that it can perform both a horizontal loom, rope making, and positive material lathe, at the same time. The triplex operation, along with added continuous feed resin, can feed the end product into awaiting plastic for vacuum bagging and curing. With a continuous feed oven, the production can operate continuously, or as needed, with any length desired. Continuous Weaving Mould: Since spooling materials for the loom and be changed on-demand, and on-the-fly, different materials can be incorporated as needed, to form hull strength, shape, support, channels (for Pex piping, electrical runs, etc.) and even for forming a jelly-roll (battery or supercapacitor roll formed storage structure). Using carbon fiber tow, or other strands, single fiber or complex weaves can be incorporated in-situ, for the desired weave. Bubble pack (or other smaller structures) can also be incorporated on-the-fly as a add-on loom module. Bubble pack (or air pack) strands can be made onsite with resin pellets (recycled HDPE, and other materials), heated into film, then vacuumed into a rotary mold that dictates the shape and size of bubble. The purpose of bubble pack is for secure light weight floatation filler.Templates: When the CWM can’t be used, templates are used when needed. Larger sheets of material are waterjet or laser cut, or marked as needed. Mould: Smaller items, like a sink, can be vacuum moulded or material glass molded as needed. While stainless steel would be preferable (for items like a sink), HDPE would be a very low cost option for material, and can be heated and blow or vacuum moulded.Structure: Flat or semi-curved structures made from lightweight honeycomb material, or plywood, can be glassed and vacuum cured. Thin material, such as thin plywood, can be laser cut, and layered up for structure. Between layers can use bubblepack, or foam, similar to SIPS.Deck Structure: Made from UV-tolerant material, made in U shape or similar, to provide structure between hulls. Holes or gaps provide tie-down anchor points. Can be bolted to hulls or hull cross beam, or lashed, as needed.
