Ingenious Design for Portability and Functionality

Ivan Miranda's creation pushes the boundaries of additive manufacturing, moving beyond mere prototypes to deliver a fully functional, rideable electric scooter. The design centers on extreme portability, allowing the entire vehicle—including its structural panels, mounting brackets, wheels, and various mechanical parts—to be neatly packed into standard luggage. This revolutionary approach tackles the challenge of transporting personal electric vehicles, offering a practical solution for urban commuters and travelers alike. The scooter's modular construction underscores a forward-thinking vision for personal transportation, emphasizing convenience and accessibility.

The core innovation lies in the scooter's capacity to break down into its fundamental constituents. Miranda's objective was to determine if a complete transportation device could be entirely produced using additive manufacturing, then conveniently packed into typical travel bags and subsequently reassembled upon reaching one's destination. He put this concept to the test by journeying to Maker Faire Prague with the scooter dismantled, where he successfully reconstructed it on-site. This accomplishment earned him recognition in a competition for projects designed to be compact enough for luggage. Without its battery modules, the final product weighs slightly more than 14 kilograms, making it an exceptionally light and manageable travel companion.

Resourceful Power and Advanced Mechanisms

The scooter incorporates repurposed components and clever engineering to ensure both efficiency and robust performance. Miranda adapted lawn mower tires for the wheels, strategically narrowing the 3D-printed rims to achieve an optimal rounded profile for superior turning capability. This smart modification allows these otherwise mundane components to mimic the handling characteristics of specialized scooter tires. Powering the ride are two 36-volt power-tool batteries, feeding a belt-driven hub motor, while an Arduino system meticulously manages throttle input and lighting functions, illustrating a harmonious blend of recycled materials and sophisticated electronics.

Further enhancing its innovative design, the scooter features a bi-stable kickstand that securely locks into position, and a hinged 3D-printed seat that conceals a practical storage compartment. A modified bicycle disc brake system, featuring an enlarged central opening and an adjustable caliper, ensures reliable stopping power. Miranda's continuous refinement has focused on replacing metal parts with 3D-printed alternatives, minimizing the need for specialized hardware and making the assembly process more accessible. While offering detailed construction guides and digital files, Miranda cautions that the scooter remains an experimental hobby project, not yet certified for road use, highlighting the ongoing development in this exciting field.

MVRDV's 'Shift Embassy' in Rotterdam: A Landmark for Ecological Change

MVRDV has emerged victorious in an international competition, earning the right to conceptualize the 'Shift Embassy,' an ambitious cultural hub slated for Rotterdam's burgeoning Waterkant district. This groundbreaking initiative, driven by the social enterprise Shift, seeks to inspire ecological and societal advancements through architectural innovation, captivating narratives, and community-focused programs. The architects envision a terrain-like structure that ascends from the Maas riverbanks, guiding visitors through lush landscapes, tiered platforms, educational exhibits, and scenic overlooks, all while maintaining a deep connection with nature.

The 'Rotterdam ROCKS!' proposal challenges the notion of a conventional, isolated monument by transforming a significant portion of the building into an accessible public space. Comprising seven stacked, permeable volumes, the design features a series of cavernous interiors and elevated terraces, seamlessly connecting various exhibition areas, hospitality services, and outdoor pathways. Guests can ascend the building's exterior to reach breathtaking panoramic viewpoints of Rotterdam. Furthermore, the facade of the building is designed to integrate vegetation, water features, and habitats for local wildlife, extending the future tidal park vertically and directly weaving ecological systems into its architectural fabric.

The project's vision extends to its operational aspects, aiming to serve as a comprehensive testing ground for low-carbon construction. MVRDV's Rotterdam-based team intends for the Shift Embassy to meticulously document the successes and shortcomings of various building strategies. This initiative positions the project as a large-scale research facility for emerging sustainable construction techniques, all while endeavoring to minimize its environmental footprint throughout the entire development process. The design also thoughtfully addresses a fundamental paradox: often, the most sustainable structure is one that already exists. Rather than presenting a definitive solution, the architects contend that any new construction must justify its environmental impact through circular design principles, enhanced biodiversity, the use of low-carbon materials, and long-term adaptability. Consequently, the proposal will experiment with recycled steel, reduced-carbon concrete, bio-based materials, and components engineered for future disassembly and reuse. The building's environmental performance, encompassing energy generation, water management, biodiversity, and material consumption, will be transparently monitored in real-time, making its ecological systems an integral part of the visitor experience.

This innovative design by MVRDV represents a harmonious blend of experiential engagement and ecological responsibility. It goes beyond merely hosting climate change exhibitions; instead, it leverages architecture itself—through its landscape integration, biodiversity initiatives, public accessibility, and material experimentation—to convey a powerful message of sustainability and hope.
