Warning:I don't have time to revise my physics so what you will be reading is just my imagination.
1)The invention that help us use solar energy without worrying about cloud or weather condition.
2)The invention that can bring distilled sea water to desert.
3)Backpack farm,the invention that can produce food in every 4 hours ,and we can use it in spaceship or on any planets.
As for the invention that help us use solar energy without worrying about cloud,we might build solar tower that is higher than 80km or the highest cloud.
If this is not a good idea because there are many problems such as material and wind,we might build solar pyramid whose height is less than 80km
,and use SFO(Solar Flying Object) that can fly with electrostatic force to change the direction of sun's beam to the solar panel on the surface of the solar pyramid as the following image shows.
If SFO(Solar Flying Object) has charging conductor,we can use it to charge electric car as the following image shows.
Oh! wait! If we can sit inside SFO(Solar Flying Object),why do we need to use electric car.Wow! I just discover a new kind of vehicle.
By the way,you should not believe every legend that you've heard,for example as far as I can remember,I've never seen men in black and I've never heard silent helicopter.
As for the invention that can bring distilled sea water to desert,I can't imagine how to bring the container back to the sea level to reuse it again after it was moved to the highest point.
Actually,you don't need to use a container,and you should try to use the pressure from the level of the sea water and floats.
Besides,we need to protect the tubes that bring distilled sea water to the desert from earthquake and wave. I try to imagine multiform tube that is composed of many spheres but there are no any images work.
As for backpack farm that can produce food in every 4 hours,if we have the backpack that can produce mushroom or seaweed that has both carbohydrate and protein,this backpack
might help scientists and learners have time to save their lives and our knowledge because they are unlikely to depend on politics,economic recession and weather condition anymore.
Actually,we don't need to produce solid food.
Note that no matter destiny controls our subconscious or not,we should try to imagine anything that might be the solution of our problem or try to imagine every combination.
Our scientific knowledge depends on trial and error anyway.At least we help the next generation not to waste their time.
