Heat Retention Science Projects | Sciencing Heat retention refers to the amount of heat an object or material can store overtime. ... The objective of this project is to determine which type of water—saltwater or freshwater—is the best at retaining heat. According to Free Science Fair Projects, start by filling both containers with two cups of water, and then mix four tablespoons of ... Bathtubs That Retain Heat | Hunker Soapstone, Brass and Copper. Known as a higher-end choice for a bathtub, soapstone is an excellent choice for heat retention. Although this type of bathtub is dependable for its ability to hold heat, its cost and limited style options can be drawbacks. Brass and copper retain heat very well and resist denting due to the thickness of the materials.

A material that keeps its cool when hot | Max-Planck-Gesellschaft A great deal of energy could be saved if turbines and combustion engines operated at higher temperatures than they currently do. Ceramic high-temperature materials make this possible. Martin Jansen, Director at the Max Planck Institute for Solid State Research in Stuttgart, has been conducting research into just such a new material for 20 years. It is now ready for the market.
