I thought of something really cool. What if we can make shileds to help us survive in extreme heat and cold temperatures of air, and waters? The cold sheild can provide us protection against the sun's heat way, keeping us cool on the inside, heck you don't even need to roll in bed to stay cool in all. As for the warm shield, you can put this energy field around you to protect yourself from the frosty winters without wearing a coat or anything like that. it will keep you warm through the snow you step in. i imagine these sheilds being exoskeleton thick layer. That's just a possibility theory i came up with. Leave some comments to show wether you think this would work. Then, i'll try to make the exercise on using them once i figure it out, and post it on the shielding page.
