I'll give you one case of NTFS being irrecoverable with built-in Microsoft Tools. Do you remember when Vista SP1 was bricking computers? That was caused by an error in the CLFS that was not repairable by any Microsoft computer, XP and below didn't know there was a problem and Vista BSoD (0xC1F5) when attempting to mount the drive.

The fix? You had to mount the drive using ntfs-3g on a *nix box and delete the contents of the \$Extend\$RmMetadata\$TxfLog directory. GG MS. Took me HOURS to figure that one out. :P

Because for fusion you need heat, pressure, and fuel. The sun's gravity provides the pressure required, here on earth we need to expend energy to make that pressure, which is why we haven't came up with a self sustaining version of fusion here on earth.
