Handmade Organic Fruit Extractions
Francisco Jimenez, Fruit Technician







"The idea basically is to hack fruits, fermenting them to get a variety of a new quality products, including Vinegars, Syrups, Compost, Fertilizer, and Pesticide. There are so many ways of hacking ripe fruits in the fresh vinegars process. We can use tropical fruits like bananas and pineapples, and local fruits like apples, strawberries and figs. We can work manually with some of them, and other fruits like apples are better processed with an electrical extractor."

Solar Thermal Popcorn Generator - Ky Faubion, inventor 


"It's a 42" Fresnel lens mounted on a lazy susan type turret with pitch adjustment to face all angles adjacent to the sun. When the spot fresnel lens gets in the direct sunlight it reduces a square meter of sunlight into a half inch reaching 2000 degrees F. It's self automated through using an NXT controller and can be blue tooth operated from a smart phone if the need arises."

Homeowners can use Energy Computers to integrate their solar-generated energy and grid energy in the most economical way.

Construction contractors and emergency responders can use Energy Computers integrated with PV as mobile energy systems to replace polluting generators and alleviate the burden of fuel logistics. Communities and utilities can use Energy Computer networks to integrate renewable energy from residences and businesses onto the power grid. Green data centers can use Energy Computers as backup power and to maximize the value of renewable and grid electricity.

 

The Energy Computer is a hardware/software platform for storing electricity and intelligently managing it. An on-board CPU and the Energy Operator System provide the computation and logic for managing power (kW) and energy (kWh). An application interface allows the exchange of information and energy with any energy-related hardware, such as appliances or other Energy Computers in the network. The power inputs (electricity) can come from any source — such as from a solar energy system or from the grid.

 

You operate an Energy Computer using local and web-based software applications that allow you to visualize energy flows, select energy sources, and recharge your storage modules. Any number of Energy Computers can be linked together to form a micro grid — the communications and energy storage technology necessary to manage and distribute energy in your network.

 

 Learn How To Build Your Own Wine Turbine.


As seen at the Make Fair 2008, Brad Hunter will be sharing how to construct a basic Savionus turbine for making DC power.  Brad will also be explaining how to make use of that energy and include plans for doing all of the above.    

 

Gathering energy from resources that are renewable, such as wind or sun and using it instead of fossil sources greatly reduces demand and use of those fossil sources.  At the same time, CO2 is reduced as a direct offset for any energy produced by these two natural sources. Brad will allow people to handle a sample N43 magnet and create electricity with their hands in order to light an LED.  This is based on Faraday's early experiments, and helps illustrate the main electrical piece of the project.

 

Brad has worked with The Gathering, and he is solar power Construction Manager for the Mt. Diablo Unified School District Board of Education,  installing the largest K-12 solar project in the nation.  Visit him in the DIY area of Earth Day SF.
