Geothermal building cooling system

Geothermal Cooling System by Green India Building Systems and Services Pvt. Ltd. (GIBSS) is an innovative technology that replaces the rejection of heat to ambient air in the conventional systems by the rejection of heat to ground. In conventional air-conditioning systems, the cooling efficiency depends on atmospheric temperature. If the atmospheric temperatures are higher, efficiency of the air-conditioning system is lower and vice versa. The key innovation behind Geothermal Cooling System is the designing of a heat exchanger system that uses the earth temperature, which is much lower than atmospheric temperature to reject the heat. Lower temperatures significantly improve the efficiencies of the air-conditioning systems.

Energy efficient ceiling fan

Atomberg Technologies aims to use their innovative Gorilla Ceiling Fan to reduce power consumption of cooling compared to conventional fans. The company claims that, whereas other fans consume around 75 Watts at full speed, Gorilla fans consume only 28 Watts; achieved using a brushless DC motor design and a driving algorithm called “atomsense”, which precisely senses various motor parameters in real time and controls the motor in a closed loop, avoiding power losses.

Solar-driven ferries

NavAlt envisions a more efficient water transport system which doesn’t use fossil fuels. Navalt’s inland passenger transport solution, a solar-powered ferry, does not pollute the air or water. This also avoids smells from diesel. It has low noise and vibration, lowering rates of noise pollution. The ferry reduces the daily operating cost to 1/40th of a diesel ferry. The innovation has been tested and used for prolonged periods of time, succeeding in the beforementioned factors.

One hundred percent biodegradable sanitary pads

Saathi’s 100% biodegradable sanitary pad is made from an agricultural by-product, banana fiber. The fiber is one of the most absorbent and abundant natural fibers in India. Unlike wood pulp or cotton, the raw materials for Saathi’s sanitary pads don’t require additional land since their feedstock is from agricultural waste. They do not contain any bleaching chemicals, thereby minimizing skin irritation and the release of toxins into the environment upon disposal.

Biomass combustion for heating and cooking

The population in the Himalayas largely base their heating on coal or wood, which is problematic due to deforestation and air pollution among other things. In addition to having using several techniques for improving the efficiency (such as pre-heat airflow channels and bell-effect heat trapping), The Rocket stove has a secondary combustion chamber where unburnt material is used to provide otherwise lost heating energy, which reduces fuel demand by 50% and smoke pollution by approximately 90%.

Integration of energy storage from kW to MW

The solutions aims to support energy storage technology. Energy storage is made more efficient by the proposed standardization from the company. The application range is wide, allowing for standardization to be used in more cases. There is also a proposal for energy storage system farms. Increased storage can enable more intermittent renewable energy to be produced.

Integration of solar into microgrids using batteries

SwitchDin Pty Ltd is simplifying integration of solar and batteries into micro-grid and edge-of-grid services by using a local controller called “Droplet”. It enables site energy control, management and coordination. By connecting to a cloud platform, “StormCloud”, the individual Droplets are supported with data. Furthermore, connecting to the cloud allows individual controllers to cluster using a long-range communication system, which can help secure the service for areas not supported by cellular networks.

Energy efficient portable cold chain solution

The innovation is a cooling box with a fast-charging eutectic thermal battery. According to the company, they have reduced the common 14-15 hour charging time to 4.5 hours. This helps increase viability of the battery as well a serving as a reduction of operational costs. By combining this battery with stand-alone cooling boxes, the company allows for stacking of individual boxes, thus reducing the need for refrigerated trucks. The company states that the cooling solution can be used on most vehicles including two-wheelers.
