Green Tech Vibes Yokohama

Wish you could code with minimal effort, earn passive income, travel anywhere, and still do something good for the planet? Good news, Vibe Coding makes that almost possible.

“Vibe Coding” simply means: you describe what you want, and AI writes the code for you. You can build websites, apps, or even WordPress themes that make money while you sleep💰 Sounds incredible, eh?

But here’s the catch: some people succeed, many don’t, because fixing issues is hard without technical knowledge😇

At the same time, AI growth has a high impact on the environment. Data-centre electricity demand may more than double by 2030. In Hokkaido, where all of my family members and school friends live, a nuclear plant is restarting to meet this demand, and PFAS has already been detected in the river near a new semiconductor factory🏭

New tech is exciting, but it’s affecting nature and may affect our health.
Still, we can’t work without AI anymore. So how do we use it wisely?

In this session, we’ll try building a simple web app that solves an environmental issue using Vibe Coding in fewer than 5 prompts, powered by our collective knowledge.👩🏻‍💻👩‍🎨💬 🤖

If you’re not in tech but want to help make the world regenerative, no problem, let's learn together. If you are tech-savvy, your professional brain is highly appreciated!

Join us, a place to think deeply together and turn knowledge into climate action🌲
