The Re: LAMP team has worked with local bio-materials to explore low carbon and low embodied energy design concepts, work flows and prototypes for solar lighting.

Empirical models explore the use of tension and the flexibility of bamboo to develop a lightweight, rigid and reusable structure inspired by the rigging of a sailboat. Bent bamboo testing by Ching Ying Ngan.

The Re: LAMP kit of parts provides everything a community or individual needs to produce and maintain their own energy infrastructure. Assembly is straightforward and does not require any special knowledge.

Re: LAMP links the material flexibility of the bamboo streetlight to its programmatic adaptability in a tension and compression strut system made for a single stalk of bent bamboo.

Adjustments are as simple as untying a knot, making required changes, and re-tying the knot again. Knowledge and skills required to fix and upgrade the lamp can be learned to customize the streetlight.

Individual Re: LAMP units can be aggregated into larger organizations to support different programs and create new spaces within a community.

Areca palm leaves are widely used in Karnakata by entrepreneurs as a natural material for organic bio-degradable disposable plates, table wear, trays and packaging.

The Re: LAMP project explores how areca leaves may be used in traditional factories for different applications. Areca palm leaves are gathered, dried, then cleaned and soaked before being pressed into bowls and plates.

The research team includes small scale areca factory owners and the design and manufacturing process were modeled for the factories’ typical machines, with cold mould modifications to eliminate the need for diesel fuel.

The areca home light transforms a single leaf of areca into a functional, renewable, inexpensive and locally-sourced fixture for the NGO’s carbon-zero home lighting system.

Re: LAMP takes advantage of areca’s flexibility, and introduces functional adjustability via a “living hinge” and twine tension adjuster that allows the light to be task focused or more ambient.

The Re: LAMP research project uses design to explore the applied use of renewable biomaterials to create carbon zero solar lighting systems in India. Solar street lighting is the most rapidly growing sector in the global solar market, yet its constituent materials - steel, concrete, molded aluminum, and plastic - are far from ‘green’. The project integrates the study, testing, design and prototyping of biomaterials with innovations that combine ‘hi’ and ‘low’ tech manufacturing found in rural villages. Holistic management strategies that utilize soft infrastructure expand economic opportunities for existing, local manufacturers in biomaterial production and solar streetlight entrepreneurship.
Working with skillsets of semi-nomadic tribal harvesters, renewable bamboo streetlights are grown with a simple, pre-formed spring camber, using an adjustable 3D printed collar. The research demonstrates how the ‘weakness’ of a single stalk of bamboo - its bendability - can be leveraged to create a new level of lighting flexibility, portability and adaptability that transforms western, modern ideas of fixed streetlight infrastructure.
Working with an Indian start-up in Bangalore and with a local areca leaf plate manufacturer in Ujire, the research team determined the minimum bending radius of wet areca leaves. To reduce carbon emission and diesel powered molding machinery, the team created a digitally fabricated cold-molding form and process to modify the local plate manufacturer’s existing equipment and work flow, which enables the owners to expand their local employees. Taking advantage of the bending “weakness’ of molded areca, a biomaterial living hinge was developed in the first product: a home lighting system. Prototypes are now underway to substitute areca for the investment molded aluminum and plastic streetlamp head.
With conventional polycrystalline solar panels and re-cycled rechargeable batteries, this research demonstrates that it is possible to save over 400 kg of carbon emissions per light, through the use of native, abundant biomaterials and local, distributed manufacturing. When the materiality of infrastructure changes, a cascade of new possibilities opens up. The Re: LAMP project is intended to serve as a memorandum to the solar lighting industry that colonial assumptions of top-down ‘hard’ infrastructure need to be challenged, and that embodied energy “in” as well as operational energy “out” must be considered. There are viable alternatives to constrained oil based resources. New industries, components and livelihoods can be designed and grown with abundant, renewable and local biomaterials.
