How is the new energy sand table model made

1、 Conceptual concretization: ecological logic in the design phase

Using the "scene slicing" design method, divide the 3.6m × 2.4m sand table into three narrative units:

Energy production area: 45 ° inclined arrangement of photovoltaic matrix, transparent acrylic board interlayer sandwiched with LED light strips to simulate photoelectric conversion

Smart energy storage station: 3D printed containerized battery pack with modular display of internal magnetic attraction structure

Low carbon community: Micro vertical farms and photovoltaic carports form living units, and resin molded resident sculptures present dynamic living scenes

2、 Material Revolution: Practice of Sustainability Models

Breaking through the limitations of traditional model materials:

Architectural complex: Recycled ABS plastic laser engraved prefabricated buildings, with window frames made of annealed copper wire bent

Surface system: epoxy resin mixed with coffee grounds to shape the terrain texture, CNC engraving machine milling drainage ditches

Vegetation layer: Using electrostatic flocking technology to produce moss, 3D printing trees with implanted magnets to achieve seasonal changes

3、 Dynamic Narrative: The Dance of Light, Shadow, and Machinery

Day night system:

Arduino controls 200 sets of WS2812 LED chips, with a program setting for a gradual transition from dawn to noon, dusk to moonlight in four time periods

Energy flow:

Inject glycerol based simulation solution into a transparent conduit, and drive the "green electricity" to circulate in the power grid with a micro pump group

Human computer interaction:

NFC tags are embedded in key areas, and the carbon neutrality data of this module will pop up when visitors touch their mobile phones

4、 Macro Reality: The Secret to 90% Restoration

Industrial texture:

Tiangong TS-38 spray can base, powder painted old power transmission and transformation equipment, rust stains accurate to bolt level

Ecological traces:

Fix 0.3mm simulated fallen leaves with UV glue, calibrate vegetation distribution through micro drone aerial photography of real scenes

Data visualization:

Laser engraved acrylic data card, dynamic display screen presenting real-time carbon footprint calculation
