Can I Install a Game to Playstation 3 Hard Drive?

I was wondering I just got this ps3 traded my 360 for it!! and when I had the 360 I would install the games to the xbox 360s HDD and play from there to keep the 360 running smoother. I was wondering if there was a way to do that with the ps3? I am not talking about backing up files/games, making burned games or MODDing or anything like that, Just simply playing from the hard drive with the original bought game from store in the ps3 console. To keep it from using so much energy and keep it cool. and do the intercooler fans work? I heard they block the actual fans inside the console. Which make the systems more prone to overheating.

Suggestion:

Its impossible and here's why.

1. If you could then you could sell the game disc to one of your friends, and sony will lose money.
2. Even if you could a PS3 game takes up-to 50 GB so if you have the 80 GB version like me you only could have one game in.
3. Its faster to eject a disc that to delete something, when I press the disc eject on the ps3 it takes about 3 sec till its out. Try deleting a 50 GB or copying it via USB, usb have a theoretical speed of 480 Mbps basically 60 MBps. So you take 50 GB and divide it with 60 MB, 50.000/60MB is 833 sec and divide it with 60 (bc there is 60 sec in one minute). Where you get 14 min to transfer a 50 GB disc, now this is theoretical which means you'll most likely never reach these speeds, so maybe 20 or 25 min.
4. Every nerd knows that the more data you have on your hdd the slower the system will get, bc the computer have to search all the time. So why do you think they use disc in the gaming world.
