I'm standing in the forest - I'm green and brown - who am I? "Dr. Baum" - says the little girl with the breathing problem. You could therefore assign a tree to each child, which they study for 3 years, take care of and give it a name - for example "holiday"... They get a certificate for this entitled "Tree Shepherd" with a photo of the tree. The first step to the forester and better air...

The idea for scanning a planets surface is, to throw 1000 little robots  (who can climb mountains) by special parachutes (who will be destroyed after landing by an acid cloud) with a camera each, different perception instruments and a transmitter (strong enough to sent information to a satellite in planets orbit, who sents its further to Earth) each, on the whole planet to discover, than to invest all in one very expensive thing - with the side effect - if 200 of this little rover spiders broke on landing it would be not so worse at all...

In flood areas (also due to climate change in the future) basements in the houses could be converted into watertight submarine rooms with appropriate bulkheads (at doors and windows) so that the belongings there are not damaged in the event of a disaster until the water in front of and that's why it was pumped out...

small drones in the form of bees that fly to a place to vaccinate people with their stinger on a marked spot (shoulder)...

For the restaurant: Automatic serving of food and drinks on a truck in a tunnel, where the flap can only be opened at the customer's table to take something out when the small lamp there lights up.

A local "library of deceased persons" with one (e)book per person: photo on the cover, personal digital content (with USB connection) and a compartment for the ashes from the crematorium... (I think that kind of idea is already in America)

A code generator creates a program part from (language) models, which is then combined with others with the help of "artificial" intelligence (creative but possible) into a program that "only" serves the purpose of research and makes students think or laugh ...

"Artificial intelligence plays against artificial intelligence to *train*..."

Why not a computer game for the home where you can fly around in a spaceship in our real milky way / galaxy and experience fantasy adventures (so it's also *real* fun...)?

100 computer players (gamers) are invited to a LAN party, where various games are played continuously (without a break) in the network until all players (except 1) have given up. The last player receives a large prize money. say the judges...

You drive in the center of a transparent, artificial, rotating ball (which has fine rubber strips as a profile) on the roadway / road. The drive takes place via ball bearings with electrical energy. Forces of attraction keep the helm seat level....

A software program for the (children's) PC, where you can select / compose a song that an animated orchestra then plays on the screen after any assignment of the melody to the musician - which could be amusing...

Listen to 3D music in a colourful, floating space filled with speakers - perhaps in zero gravity...

Because of the invention in the book "The Wizard of Oz" by Lyman Frank Baum with Dorothy's flying house, the idea came up to have a mobile house (with all his personal belongings) with which one can travel the world. The journey could work with the help of rotors (like a helicopter) on the roof. For this you would still need worldwide landing sites (with connections for electricity, water, etc.) at tourist locations (beaches, mountains, forests, large cities)....

to artificially reproduce special organs of perception of animals such as the "tapetum lucidum" or the "Jakobson organ" and to use them for meaningful purposes (e.g. for measurement)...

The idea was to "coat" the nails (during manicures/pedicures) with a kind of breathable membrane (which is not carcinogenic/mutagenic); The problem with normal nail polish is that some of the ingredients are harmful to your health. It is important that the nail is not impermeable to pollutants. "Gore-Tex" implants are already used in medicine...

a film or game should appeal to all senses. Why not an olfactory device for generating smells in addition to the visual and acoustic response through the monitor and loudspeakers..? :-D

Glasses that let us humans see the ultraviolet *world* of insects...

An additional keyboard (with USB connection and software) on which 100 faces of your favorite stars are drawn - if you press a key, all work titles, films and information (from the Internet) about the star appear on your monitor - fast switching included. ..

With regard to the € banknotes, there are security features - pure, starch-free cotton, intaglio printing process with steel engraving, see-through register, metalized security thread, microwriting, black light colours, IR light properties, serial number, NZB identification, plate code, hologram strips, watermark, a green value digit with tilting effect - in order not to allow the forbidden counterfeiting - how about, if necessary, printing out a legal digital photo for the other person in exchange for a coke or a roll?

"Can't you install a fine 3D grid with sensors in the metal parts of a car so that the car computer can immediately see when and where something is brittle, deformed or worn out?" Better than "X-raying", right? xD

a new additional "horn" for clever bikers with solid digital technology, rechargeable battery, loudspeaker, mini amplifier - so that you can play any tones and sounds from the USB stick at the push of a button: You could choose from: muuh, pssst, hey, plopp , schhhhhhh, peeep, rrooooah, cuckoo, rocket, bang, etc. - every biker has to know for himself what to use it for and when...

A country has the right and freedom to self-determination. It occurred to me that it can also redesign its flag itself, since many flags are from earlier times (even before the Enlightenment) and a lot has changed since then. Then why not a more modern flag (which people like) that symbolizes new views. For this one can take the location into account and combine deductive with inductive views (maybe even make a color gradient) - for this one could use the global color concept (lower 4 pictures) on the watch page..
