Mapletree Gold Prize



In line with the Singapore Green Plan 2030, 60,000 Electric Vehicle (EV) charging points will be installed by 2030, to drive EV adoption in Singapore.

Team PowerPod proposes the idea of using a mobile battery charging system for charging EVs, as opposed to charging EVs at fixed charging points. The mobile system harness energy from solar power and is also an Energy Storage System.

The centralised battery charging system, powered by a robot, locates your EV with the help of IoT in a shopping mall carpark. After 1-2 hours, there is enough power charge for the EV to cover a distance of 100km. It  maintains sufficient battery charge on a daily basis, and eliminates the hassle of finding an EV charging point lot that could be occupied during peak periods.

Squid snack

The oceans are running out of seafood. Global average consumption of fish and other seafood reached a record high of 20.5 kilograms in 2019, according to the World Economic Forum. 

With the need to preserve the ocean habitat and address the microplastic pollution in the oceans, Team Sea-No-Meat suggests consuming plant-based food options as substitutes for seafood. 

The team proposes the production of ‘Çumil’, a plant-based squid snack made from yellow peas and konjac. High in dietary fibre and being trans-fat free, the easy-to-prepare snack offers a healthier food option to the consumer.

The Beans

Coffee soba noodles

Coffee, the second most consumed beverage in the world, generates six million tonnes of waste annually. 

The Beans team propose the idea of repurposing spent coffee ground into coffee nibs, small pieces of crushed roasted coffee beans that have a bitter, chocolatey flavor and are a good source of fibre, protein and healthy fats. 

Produced by the team, the nutritious nibs would be used as food additives and can be added to a range of food products including energy drinks, protein shakes and low GI baked goods. For example, the team proposes to add 5% of coffee nibs to the production of Coffee Soba noodles.

    Tapping on the high humidity levels and sunny climate in Singapore, the team hopes to create a sustainable water generation equipment which converts oxygen into water using solar energy. ‘Air Aqua’ would facilitate water consumption on-the-go with the fitting of this equipment on electronic billboard displays at bus stops. Water vapour which flows into the system condenses into water droplets which is accumulated in an internal storage tank. This allows the end users to fill up their bottles via a water discharge outlet connected to the storage tank. The discharged water is safe for consumption.

    Bronze Award

    Senses Blue

    This water efficiency system aims to eliminate water wastage in public restrooms, where users tend to commit “double/first flushing”, a redundant practice of flushing the toilet bowl before usage. The innovation also aims to improve restroom hygiene standards by integrating the antiseptic detergents with every flush. The technology, made up of both hardware and software aspects, takes into account the PH level of the standing water. Sensors and dispensers are to be installed in the toilet bowl, and a software programme will process the PH level readings to categorise if the water is “clean” or “dirty”. This will then allow the system to inform the user via an attached screen, who will then have a choice to select a non-flush or a half-flush, if the water is clean. A full flush will be activated if the standing water is found to be dirty. Antiseptic detergent will also be dispensed together with each flush to help eliminate bacteria.

    The innovative idea was developed in close consultation with SIT’s industry partner Khoo Teck Puat Hospital, who provided feedback on the issue of redundant first/double-flushing.

    Hotels have been found to top in energy consumption across various building types. To mitigate this, the team proposed for hotels to incorporate an existing tile technology system that converts patrons’ footsteps into energy and data. To be installed in high footfall areas such as hotels’ lobbies and function room foyers, the system could offset part of the hotels’ energy consumption. The innovation also proposes for an integration of Bluetooth connectivity to register event delegates seamlessly, eliminating the use of tickets and time required for registration. With customisable shapes, colours and textures to suit the hotels’ interiors, the tiles can help hotels reduce overall fossil fuel energy consumption, enhance data collection, and improve brand image through corporate social responsibility.

    Lapis Bikes

    Carbon fibre bicycle frame is sought after due to its light weight and ability to absorb vibration. However, the downside is its high cost. The Lapis Bike proposes an alteration to the manufacturing process by using 3D-printed moulds and inserts. The production and R&D costs can be reduced without compromising the structural integrity of the carbon fibre bicycle. Moulds can be melted back and subsequently reused for another new mould. The result is a bike frame made of carbon fibre, coupled with 3D-printed sandwiched structure, created from the stainable 3D-printed mould.
