8 Ideas not yet developed or published to the world!

1.  A portable real-time translation device for communicating with people of different languages: This device could use natural language processing (NLP) and machine learning (ML) technologies to enable real-time speech recognition and translation. It would also require internet connectivity to access online translation engines.
2. An automated underground transportation system to reduce traffic in cities: This system would require advanced technologies such as automation, control systems, and sensor technologies to operate the vehicles and navigate through underground tunnels. It would also require communication technologies to coordinate the movement of vehicles and ensure safety.
3. An intelligent waste collection system that automatically separates different types of trash for easier recycling: This system could use sensor technologies such as cameras, weight sensors, and RFID tags to identify and sort different types of waste. It would also use machine learning algorithms to continuously improve its sorting accuracy.
4. A sustainable energy solution based on generating energy from biomass of organic waste: This solution would involve technologies such as anaerobic digestion and gasification to convert the organic waste into usable energy. It would also require technologies for capturing and storing the resulting energy, such as batteries or fuel cells.
5. Virtual reality technology for training professional skills, such as surgeries, repairs, etc: This would require virtual reality headsets or other immersive display technology, as well as software for creating and running the virtual training scenarios.
6. A personal assistant robot that helps elderly or disabled people with daily tasks: This robot would use a combination of sensor technologies, such as cameras and microphones, to perceive its environment and interact with users. It would also use natural language processing (NLP) and machine learning (ML) technologies to understand and respond to users' requests.
7. An integrated health monitoring system that tracks vital signs and sends early alerts in case of health problems: This system would use wearable technologies such as fitness trackers or smartwatches to track vital signs, and it would also use machine learning algorithms to analyze the data and identify potential health issues.
8. A food production system in urban spaces using hydroponic and vertical farming techniques: This system would require technologies such as LED lighting, precision irrigation, and nutrient delivery systems to support plant growth in an urban environment. It would also require advanced control systems to optimize growing conditions and maximize yields.

Technology for each of these ideas is available, but some of them are not fully developed or not widely available yet. But these are ongoing research and development.
