okay. heres the idea. if i had the leftover money (long story about that
), you could make a freediving pool. heres my idea. get some people that are specialy trained in digging wells. so get them to drill you a 100 foot deep 5-5 meter (minimum) pool. then hire a pool company to spray on the lining and all that. and heres a cool though, at the bottom put a "cave" (sorta like how the beavers do it) that you could go into, that would have air (just be sure to blow bubbles onthe way back up, as it would be compressed air!) im sure it would cost plenty of cash, but nothing TOO huge. just sacrifice $100,000 on it by buying a smaller house.
you woudl also need something to keep it warm, as i imagine it will get cold down there. i say just take surface water (which could be solar heated) or an extra heated pool and pump water (like a heat exchanger) between the two pools.
what do you think?
oh and there would be a special building around it in the winter, to 1 keep it warm, and 2 to let me get dry before hypothermia lol
PS, of course i could make it more then 100 feet, but i unno if i would ever reach my cave without tanks lol
