W2: My Invention to Save The Earth

SkyBloom: The Carbon-Capturing Airship Revolutionizing Clean Air

Climate change is progressing at a much faster rate and carbon dioxide (CO2) levels are at a all-time high in the last 3 million years. While reducing the emissions of CO2 is crucial, active solutions are also needed to remove the existing CO2 from the atmosphere. Introducing SkyBloom, a fleet of high-altitude, algae-powered airships designed to capture carbon and convert it into clean fuel. Inspired by Sustainable Development Goals (SDG) 13, this eco-invention merges biotechnology, renewable energy and aerospace engineering to tackle one of the biggest challenges of our time. 

Despite global efforts to cut emissions, the atmospheric CO2 levels have surpassed 420 ppm, which is far beyond the safe limit of 350ppm. Current carbon capture methods like direct air capture plants are expensive, land-intensive and energy consuming. Meanwhile, deforestation and ocean acidification are weakening Earth's natural carbon sinks. We need a scalable, mobile and sustainable way to reduce the concentration of CO2 in the air.

How SkyBloom Works

1. Solar Powered, High Altitude Flight

  • SkyBloom airships operates at altitudes around 60,000 feet, where CO2 is typically more concentrated.
  • Its lightweight, graphene-based solar panels covering the body of the ship provide the energy needed for the propulsion and onboard systems.

2. Algae Bioreactors Capture CO2

  • SkyBloom has a few giant, transparent bioreactors on board which are exposed to constant sunlight.
  • Inside theses bioreactors, genetically modified algae like Spirulina absorb CO2 through photosynthesis. This CO2 absorption rate is 20 times faster than that in trees. Furthermore, the algae thrives in the high-altitude sunlight, allowing them to multiply rapidly. 

3. Carbon Conversion into Biofuel

  • The harvested algae are processed into carbon-neutral biofuels, which can power planes, ships and cars.
  • Excess biomass can be turned into fertilizer or biodegradable plastics, creating a zero waste cycle.

4. AI-Guided Deployment

  • SkyBloom is fully autonomous with its AI nagivation system directing airships to CO2 hotspots (industrial regions, wildfire zones, deforested areas). 
  • This eliminates the need for humans to be onboard as there is not enough oxygen to breathe in those high altitudes. 
  • Real-time atmospheric data is shared to scientists on ground control for progress tracking.

Impact on the Planet and Future Generations

The introduction of SkyBloom will bring forth huge changes in the future. In the short term, SkyBloom will be able to remove 1 million tons of CO2 annually per fleet, which is equivalent to 20 million trees. The renewable biofuels produced using the algae also reduces fossil fuel dependence. Furthermore, the air quality in polluted regions will be improved as the fleet removes smog particles.

As for the long term, SkyBloom has the potential to reverse global warming by decreasing CO2 levels in the atmospheres to pre-industrial levels. Next, it creates a circular carbon economy where emissions can become valuable resources. Lastly, SkyBloom protects the fragile biodiversity of our planet by reducing ocean acidification and extreme weather events.

Why This Invention is Different

SkyBloom isn't just another carbon capture project or idea, its a paradigm shift in technological innovation of our time.
  • Mobile and scalable: Unlike ground-based stationary systems, the airships can chase CO2 and be where it is needed the most.
  • Profit and Purpose: The biofuel sales from the ships continually fund the expansion of the SkyBloom fleet, making it sustainable economically and ecologically.
  • Simple operation: The process of capturing CO2 is done naturally by existing organisms. Costs are only used for operation and maintenance of the airship.
SkyBloom proves that technology can potentially solve and improve the issue of climate change. But to make it a reality, we need government policies, public support and global collaboration for deployment worldwide.

W1: The World I Want to Live In

Image
The world I envision is one where peace, justice and inclusion are not just ideals but a reality. It is a world where every individual is valued, where communities thrive on kindness and where systemic discrimination and inequalities are relics of the past. This vision of mine aligns with Sustainable Development Goal (SDG) 16, which promotes peaceful and inclusive societies. But what would such a world look like in practice? Let us delve deeper through its values, structures and the challenges we as a society must overcome to make it a reality. A World Shaped by Core Values In this ideal world, compassion, kindness and equity are the foundation of every law and social norm. The justice system focus on rehabilitation rather than harsh punishment, ensuring that everyone (regardless of background) has access to fair treatment. Schools teach empathy and conflict solution, fostering a culture of understanding from an early age. Figure 1: AI Generated Image of a School in This World Just ima...

W3: A Day Without Water

A Day Without Water: A Glimpse Into Life's Fragile Balance Figure 1: AI Generated Image on Water Supply Disruption (ChatGPT, 2025) Water is one thing that we rarely think about, until it's gone. Everyday we turn on the tap and clean water flows from it effortlessly. But what if, one day, it didn't? What if your town had no access to clean water for 24 hours? The thought alone is unsettling, but exploring this scenario reveals just how much we take the water we use in our daily life for granted. The day begins like any other day, until you turn the bathroom faucet and nothing comes out. Initially, you assume its a minor plumbing issue. You then proceed to try the other faucets in your house and nothing comes out. Then, you check your phone and see the news: "Water supply disrupted due to burst pipes, emergency repairs underway." Panic then starts to set in. No water means no coffee, no shower and no brushing teeth. The simplest routines are now suddenly impossible....
