Is Ki and Chi the same thing? and are they real things?

Well i love martial arts and i like to train and just meditate in my spare time but i noticed that there are some martial arts masters that can break stone blocks and such and i feel that they use there "Ki" or "Chi" to do feats like this. How can i obtain the same thing or at least go about training to use it. Also can you pour "Ki" or "Chi" into an object to make it stronger or channel it to different parts of your body like your arm or leg to do a "Chi/Ki" punch or "Chi/Ki' Kick? i know it might sound like a stupid question but i would like some serious answers,
