Here is an elevator I made by myself that uses no Redstone and is easy to make.
Make a 3x3 square with a hole in the middle.
Next to the square, make a stack of blocks as high as you want your elevator to be.
At the top of the stack, put another 3x3 square. It should be hovering above the other 3x3.
Stack ice in the hole of the square from the first 3x3 to the other 3x3 hovering above.
Break every other ice block in the stack.
Do the same to the stack of blocks to the side of the 3x3.
Put torches between the blocks in the stack.
Wait until ice melts, but don’t take out the torches. You can break the first ice block in your 3x3 on the ground and replace it with a solid block.
Walk into the floating water blobs and hold down your jump key. Your elevator will start to carry you up.
Enjoy your transportation system :D
