Ahead of sentencing, Joshlin's grandmother, Amanda Smith-Daniels, once again pleaded with her daughter to "bring my [grand]child back or tell me where she is".

"Our chips are really thin, really small, but they get really cold. They consume a small amount of electricity in generating that coldness, but they pack one hell of a punch," says Tony Atti, the CEO of Phononic.He says that, to work at their best, traditional fridges need to be run all the time.

But thermoelectric devices can be easily switched on off. This helps to reduce the costs, energy use and space requirements."We like to present the coolness on demand where you need it," says Mr Atti.Another advantage is that thermoelectric cooling can operate silently. "That's because there's zero moving parts," Ms Rasmussen explains. "The heat is occurring because of the reaction in the material level."

In contrast, standard vapour compression systems contain pumps, condensers and expanders for refrigerant, which all generate much of the noise.A different type of solid-state cooling is elastocaloric cooling. This achieves temperature changes through mechanical stress to elastocaloric materials, which can cool down or heat up with the application of stress.

Researchers in four European countries are collaborating on SMACool, an elastocaloric air conditioner that uses metal tubes made from specific metallic alloys.

At the moment, elastocaloric prototypes have much lower cooling capacity than commercial air conditioning. And the maximum possible efficiency of SMACool is still lower than that of conventional air conditioning, although the aim is to"The wardens at the time and Peter Scott himself, I don't think they would recognise that," Mr Gowland said.

"The layout is the same. The ponds and a lot of the wetlands were created by Peter Scott, so they are there."It is just completely transformed, alive with wildlife as well, with the trees and the meadows.

"Hopefully they would be very proud of where we are."At least 120 bird species visit the site annually and thousands of different plants and insect can also be seen.
