I just realized this but there are two flaws with the Nerve gear that would make it hard to build even in SAO, the first is the Battery, if we are going by todays technology the only possible viable power source that could power it nonstop for 2 years without draining it dry is a Nuclear Battery(which uses the power of betavoltics to power it)as that is the only form of power we have that wouldn't run out after being used continuously. However if the Nerve gear was using a room temperature superconducter then the power drain would be minimal, sadly there are no room temp superconducters as far as we know.

The other problem with the Nerve Gear is even bigger problem that the power source. the other problem? Heat. All computer equipment generates heat, even with the best heatsink in the entire world, there would be a buildup of heat that would eventually cook the persons brain even without the microwave emitter going off(especially after running day after day for 2 years straight, in fact it would probably only take 3 months for the heat to build up to lethal levels.). there is no way to avoid this problem unless the nerve gear has no moving parts, which I seriously doubt is the case, as developing a system(even a computer)with absolutely no moving parts would be a nigh insurmountable challenge.

Because of these two problems, the Nerve gear doesn't seem possible to build even in the SAO universe, the Amusphere is a much more realistic VR rig.
