To see all these beautiful buildings in one place and get inspired.
A website where fans of this style of buildings can upload their photos of the ones they visited. All should be cataloged by location and other details so they can be searched for or browsed.
If you walk almost anywhere, you will see plaques celebrating and informing you of interesting people and facts regarding many places (buildings, parks, etc.) There are much more of these than you see on these plaques and many a place where there is no plaque even though it has an interesting history.
An augmented reality app that when pointed at such a place gives you a list of all the interesting things that happened. Famous people who lived there, historical events, etc. You just point it at a building or even a few buildings, or a whole park, and see the list pops up on the screen beside the place you point at. You can them click on any of these to get many more details and the story.
To save energy.
Have sensors that “follow” people and where they are in the building, and only turn on the light where they are and the immediate surroundings. Can also be smart and predict ahead, for instance when someone enters the elevator and pushes a floor button, the system can predict when he’ll arrive and light up the corridor a bit in advance. All the time monitoring all corridors and elevator behavior to optimize for all data gathered.
You have an idea. Why not quickly put it out there and have others help you shape and develop it? It’s fun, stimulating and rewarding. You could even find collaborators to help execute on it, or maybe sell it when fully developed.
An idea publication website. Make it easy to publish your idea. Others will see it, rate it, and some will join in and help you shape and develop it. There could be a marketplace for buying these ideas, and a whole system for helping to execute them (finding funding, collaborators, etc.)
