Here's a long review written by a fellow who doesn't know the difference between voltage and current and what a fuse actually does.

The question of whether the polymer and Nano-Stream treatment change the voltage point at which the fuse fails is a relevant one. Jerry Ramsey uses a laboratory grade power supply to test these fuses and has produced some interesting results. A standard fuse can handle a wider range of voltages than most people realize and can often survive at 135% of its specified voltage rating for several minutes.

The key effect of the damping liquid is to control vibration of the fuse wire. How silly can that be.

For sure,  a fuse doesn't know what the circuit voltage is until it blows,  or tries to blow but the voltage is too high and the fuse can't clear.
In normal operation the voltage across a fuse is only about 1/10 volt.

Again, the reviewer in Positive Feedback is using the word "voltage" everywhere where the word "current" should be. When he quotes 135% voltage to blow the fuse he means current. 135% is the standard hold current. It's all about the current. Granted when the fuse blows it needs to stop conducting (or clear if you like). There is a big difference between a fuse melting and vaporizing. High Breaking (ceramic sand filled) fuses can break 1500 amps where glass or non filled are rated at 35 amps. It's all on the data sheets.

I am considering making these sand-filled, Agency Approved (UL, CE, CSA) fuses available if there if any interest. The sand fill has the added benefit of stabilizing temperature and reducing microphonics. While I can't image fuse microphonics being an issue, it is mentioned in a large number of posts on the fuse forums.

Make sure they are exceedingly expensive if you want them to be taken seriously though.
