Sustainability Technology: Yirego Corporation has developed a quick way to do laundry without using electricity. With a holding capacity of up to 2kg (4.4 pounds), the Drumi, can do a load of lightly soiled clothes within about 5 minutes. Pedal operated, the Drumi can handle 5L of water for each load.
Sustainability Issue: An estimated 1.2 billion people or 16% of the global population do not have access to electricity and most of them live in rural areas in sub-Saharan Africa and developing Asia meaning without a significant change in infrastructure, they are unlikely to get grid access any time soon. Doing laundry in the developing world is very time consuming and takes a lot of physical energy as well. The laundress (or launder) has to find a water source, soak then scrub the clothes, wring them dry, and carry the clothes back to be dried out in the sun. On top of all this, the harsh scrubbing process can compromise the structural integrity of the clothes being washed. The Drumi drastically cut down on the time and physical activity. The water can be collected separately, which is probably already a daily task, and the cleaning can be done at home. With just a 5 minute cycle, approximately 5-6 loads (including hanging) can be done in one hour. Admittedly, the Drumi, at $140 is probably too expensive for some households, and financing would most likely be necessary, but a cost benefit analysis would likely show that it is a useful investment.

Wherever you find humans, you find ‘waste’. And humans never run out of waste. In the future, the majority of humans will live in megacities if we do not take any effective action to deal with the waste. To solve this problem, we should try to answer these questions that could we find a better way to handle the waste? Can we make waste decentralized and have it back at the building level so that nothing’s moving off-site?

By converting heat to focused beams of light, a new solar device could create cheap and continuous power.
A solar power device that could theoretically double the efficiency of conventional solar cells
The new design could lead to inexpensive solar power that keeps working after the sun sets
Availability:10 to 15 years
Standard silicon solar cells mainly capture the visual light from violet to red. That and other factors mean that they can never turn more than around 32 percent of the energy in sunlight into electricity. The MIT device is still a crude prototype, operating at just 6.8 percent efficiency—but with various enhancements it could be roughly twice as efficient as conventional photovoltaics
Circularity is embedded into the design of each and every Pentatonic piece — product components aid in the construction of each piece, eliminating the need for complicated assembly processes and chemical-laden glues and resins, while also minimizing unnecessary waste. What’s more, post-consumer materials are matched to products based on their unique properties and application possibilities.
Large commercial estates consume a lot of energy and in order to make these buildings energy neutral through use of solar panels, there is either insufficient roof surface or the cost of installing solar panels is too high.
Area of Sustainability: Energy
A tech startup ‘Physee’ has designed a transparent solar-powered double paned window product called PowerWindows that can convert light into electricity and can generate enough power to make buildings energy neutral. The windows have solar cells installed in the edges at a specific angle that allows the incoming solar light to be efficiently transformed into electricity.
The cost of the wiring that brings power from the grid to such windows is considerable in large commercial estates, and investing in power-generating windows would currently be more feasible for commercial use.
PowerWindows can be integrated with SmartWindows, which is another product that has integrated smart sensors in the window that sense the outside environment. SmartWindows control inside systems, such as air-conditioning and sunblinds, based on information about the outside conditions around the building.
Another product is being developed that would be coated with a special material that transforms incoming visible light into near-infrared light. This is then transported toward the solar cells in the edges of the windows. This second generation is expected to triple the energy efficiency. The coating is based on the rare-earth metal thulium that has the ability to transform a broad spectrum of light into near-infrared light.

PowerWindows is patented. Activating a buildings’ facades with solar cells will significantly contribute to making any building energy neutral. The windows can provide 50W per square meter, which can compensate up to 75% of the energy consumption of buildings, unlike solar panels that have a limited surface area for buildings or alternative smart window solutions that have low conversion efficiencies. A user can charge a phone per every square meter [11 square feet] two times a day by plugging their smartphones into the windows using USB ports.
A luminescent thin-film coating to produce clear and colorless windows can be integrated in the design of any building without compromising the functionality or esthetics thereof, making it highly suitable for the built environment.
Providing stable and clean energy in urban environment has been a great challenge for energy experts. This issue amplified by magnitudes during hot summers and cold winters when cities demand energy the most for cooling and heating. Due to highly uniformed life pattern of urban populations, energy demand usually peaks during noon when electricity-depend devices at office space are fully operating. During peak hours, fully-loaded grid also works less efficiently in delivering electricity. In order to alleviate burden of the grid during peak hours, utility companies have been imposing a surcharge per kWh but the issue remains far from resolved.
IceBank by CALMAC is a Thermal Energy Storage (TES) works as a rechargeable battery for a building’s air-conditioning system.
During night time and off-peak hours when electricity is cheaper and cleaner, water that contains 25% ethylene or propylene glycol is cooled by a chiller.
The chilled solution then circulates inside the tank, which is essentially a water tank. to freeze 95% of the water uniformly. Fully charge the tank takes from 6 to 12 hours, depending on the size.
During the day-time peak hours, the glycol solution circulates through the storage tank deliver energy to the building, augmenting or offsetting electric chiller cooling.
A fan blows air over the coils to deliver cooling or heating to the occupant spaces just like traditional air-conditioning but without consuming expansive peak-hour electricity from the grid.
A similar process would also be accomplished during winter to provide heating.
Other types of Thermal Energy Storage(TES) also exist in by using phase change materials (PCMs) or chemical reactions to store thermal energy while water being the cheapest option.
Systematically access feasibility of installing thermal energy storage in different buildings by architects and engineers.
Form partnership with utility companies to provide financial incentives for buildings that equip with thermal energy storage.
Work with building owners to determine the best TES option and start installation.
Currently used batteries such as lithium-ion and lead acid batteries take hours to charge and have short lifespan for charging and discharging. They can also be harmful to the environment. Lithium-ion batteries are unstable and can explode and cause fire.
Graphene battery storage is under production at Graphenano, a Spanish based company that develops diffierent technologies using graphene. Graphene is a monolayer carbon lattice that is harder than diamond. These new battery offers much higher energy density than Lithium-ion (1000 Wh/kg vs. 200Wh/kg on a Tesla Model S), has no fire or explosion danger unlike Li-ion, and charges in minutes, lasts longer , and 3 to 5 times smaller than Li-ion battery.
These battery can be used for electric bikes, electric motorcycles, and to store solar energy. Grabat company shows advantages of graphene-based battery over other batteries:
