Biodegradable graft copolymers derived from a carbohydrate, including nitrogen-containing carbohydrates and modified carbohydrates, and at least one &#x3b1;,&#x3b2;-unsaturated carboxylic acid derivative having superabsorbent properties are disclosed in addition to the substantially adiabatic polymerization process by which the graft copolymers are made. The methods disclosed can be carried out in a variety of currently available stirred and/or continuous commercial reactors. Polymerizations carried out with starch have surprisingly produced substantially quantitative yields of graft copolymer free of residual monomer produced as a moist copolymer. Product work-up typically involves an optional neutralization and drying.

A thermoelectric energy harvester comprises a cyclic energy input terminal supplying heat energy in a first part of the cycle to a thermal storage reservoir through a low thermal resistance generator. During a second part of the cycle, the thermal storage reservoir returns stored heat energy to the environment through an independent thermal circuit and a higher thermal resistance thermoelectric generator.
