The device is much better at preservation than the current method, cooling livers with ice.

Right now preserving livers for transplant involves cooling them with an ice cold liquid, which slows cell metabolism and minimizes decay.

That is exposing land that has not seen light of day since the so-called Little Ice Age, a widespread climatic cooling that ran roughly from AD 1550 to AD 1850.

The KoolCollar also comes with a gel filled insert that you freeze and use instead of ice (minus the secondary evaporative cooling) for indoor use, to provide cooling without the dripping water.

The temperatures eventually bottomed out during the "Little Ice Age, " a period of widespread cooling that lasted roughly from the 16th to the mid-19th centuries.

In experiments on dogs they have found that by pumping liters of ice-cold salt water into their arteries and cooling them down to 59 degrees they can preserve vital organs up to three hours after the heart stops.

While ice reflects around 80 percent of the sun's heat, having a cooling effect, blue sea water can absorb up to 95 percent of solar radiation, warming up the sea and accelerating the melting process further.
