Enefit x Build-a-Thon

Many EV owners are new to the transition from traditional fuel-based vehicles, motivated by their desire to make environmentally responsible choices. However, they often face frustrations such as range anxiety, complicated charging station experiences, and the need to manage multiple apps and payment setups across different stations and countries. The challenge is to develop a Universal Plug-and-Charge System that eliminates these frustrations by providing a hassle-free, app-free charging experience. This system should allow EV drivers to simply plug in their vehicles at any charging station and begin charging without the need for additional apps, accounts, or payment setups. The solution would benefit EV drivers globally, reducing the barriers to EV adoption and improving the overall experience for eco-conscious motorists.

Identification and Resolution of Faults Arising During the Maintenance or Construction of Solar Parks.
With the increasing construction of large-scale solar parks, often 10+ MW or even 100+ MW, the size of these parks can span hundreds of hectares. For maintenance personnel, monitoring the entire park and identifying faults, such as loose bolts, overgrown vegetation, or malfunctioning panel rows, becomes a significant challenge. Similarly, for construction workers, it is difficult to report issues over long distances or retrieve forgotten tools without having to walk several kilometers.The challenge is to devise solutions that would make the construction or maintenance of large-scale solar parks more efficient.

Solar Powered Portable Water Purification

Access to clean water is one of the most urgent issues of our time. As climate change accelerates, water scarcity is becoming an increasing problem, particularly in arid regions and during natural disasters. Renewable energy sources like solar power offer a promising solution for sustainable water purification. This challenge is timely as the world seeks innovative ways to address these pressing environmental and humanitarian issues, and solar energy has the potential to play a significant role in ensuring water security for vulnerable populations.

Waste Heat Capture from Household Appliances

With the rise in energy costs and increasing focus on sustainability, finding ways to reduce energy waste is more important than ever. Household appliances, especially those that generate heat, often release energy that is not captured or reused. By recovering this waste heat, we can make homes more energy-efficient, reduce overall consumption, and contribute to global energy sustainability goals. This challenge is timely as it addresses both environmental concerns and the rising demand for energy-saving solutions in homes.

Vertical Aestethical Urban Rooftop Modular Wind Turbine

As cities expand, the demand for renewable energy solutions that fit within densely populated areas is increasing. Traditional large-scale wind turbines are not feasible in urban environments due to their size, noise, and placement limitations. Vertical wind turbines offer a promising alternative by harnessing wind power in confined spaces. Developing a modular system allows flexibility for installation in various locations, helping cities achieve their renewable energy goals while reducing their carbon footprint. This challenge is timely as cities strive to become more sustainable and energy-efficient.

Solar Powered Irrigation Systems

Water scarcity and overuse in agriculture are growing concerns as the effects of climate change intensify. Agriculture accounts for a significant portion of global water consumption, and optimizing irrigation can dramatically reduce water waste. A solar-powered smart irrigation system addresses two critical issues—water conservation and energy sustainability—by harnessing renewable energy to provide precise irrigation only when necessary. This challenge is timely, as sustainable farming and efficient water use become key priorities for both large-scale agriculture and small-scale gardening.
