EsseyInvented things that interest me My invention is about salt water cleaner. It is basically a big machine that cleans salt water to drink. I think this would help the world because we are in a drought and we really need water. My machine would be either near the Castaic Lake Water Agency or there would be a "small" but new water agency. If we made a whole new one by the ocean there would have to be a long pipe that goes from it to the Castaic Lake Water Agency. My salt water cleaner has a large tube that goes into the ocean and sucks the water up into a large container. At the top of the container there will be a large screen that keeps out salt and trash. Some of the salt might get through so it goes through a small filter. All the salt that is on the screen will either go to a landfill or to a salt company for them to clean and bottle to sell to stores. If any water agency in the world including Castaic Lake Water Agency took my invention to use that would be awesome. If I were a scientist, I would create a machine that will solve every crisis including the economy crisis, global warming, and much more. This device will detect any burglary or crime before it even happens. This machine or device will be called "If It's Not the Nicest It's a Crisis."This device will be in everyone's home and for the bigger problems this machine will be placed in the White House, schools and everywhere, if that place needs protection. The big machines will handle any threats, crimes or attacks to the country or the place. The smaller device will be the size of a children's size two shoe. The small device will be placed anywhere except for underground. The big machine can be placed anywhere. People can shrink the size of a mouse if only the house is small. The nickname for this machine will be "Smart Companion". The "Smart Companion" will last for twenty years and never turns on you like other inventions do. The "Smart Companion" will never break and is indestructible. The chip will either be voice commanded or remote controlled. Lastly, the invention will be certificated to work and if it doesn't, all machines will be shut down and checked. If the machines ever turn on people, the chip will stop working. If that doesn't happen people will still be given copies just in case of the twenty years have passed. If I were a scientist I would invent a car that would run on air. It would have no wheels and no gas, just air. Of course, no oil.It would be faster than a normal car. If you were to put gas in it, it would explode. If you put oil in it, it would blow sky high. If you add wheels, it will fall apart.It will help the world, because whenever you go by trash it picks it up, and turns it into air. It would not spill oil or pollute the earth with gas.It will help the plants and it will help you. It's going to be the best and safest car in the world. That's what I would invent if I were a scientist.My invention would be a TV that has a lifelike 3-D screen which causes you to actually catch baseballs, throw a football, get autographs, meet the players, and smell the scents of the NHL, MLB, NFL, and the NBA right out of your own screen.There would be two remotes, one for the channels and another for food. The food one works by pressing the menu button and it will give you a list of restuarants; you choose the restaurant and choose the food you want. A tray will come out and you put the money on the tray and it will go back in. In seconds, you'll have delicious food.I would think that this device can save a lot of people money. Instead of going to a baseball game for $30, you can just sit down in a chair and you're at the game. Another good part is that everything you buy is half off. Also, it would be great for the whole family. If I were a scientist, I would create a shield that keeps dangerous people or things away from hurting someone. This device will protect people and things.The name of this shield is "Keep the Danger Away." This shield beeps when it detects danger, it opens up and it doesn't let anything or anyone that can put people in danger. This shield will also alarm you and the police so you can be safe. This shield is indestructible so nothing will hurt people. This shield will make our world better because there will be less crime. People will be protected from any danger that goes their way.
