For an automotive combustion engine only 35% of the energy produced is harnessed for motive power, with 65% of theenergy being effectively 'lost' to the environment - 25% of that lost energy is transferred into the exhaust gases. For atypical 100hp (75kW) engine, the waste heat energy is up to 50kW. As a result, automotive OEMS are looking to increasefuel efficiency through waste exhaust heat power recovery - one very attractive approach for this is the use of Thermo-Electric Generators (TEGs). To date these approaches have been too expensive due to labour intensive materialconsolidation,machining and hand assembly. As the market for these TEGs grows, it is becoming clear that unlessautomated, cost-effective manufacturing technologies are developed then mass production will be exported to low-costeconomies. The PRINTEG project will directly address this by developing advance automated technologies for: TE powderhandling and consolidation; Surface mounted pick and place and interconnect deposition and laser sintering. This willenable cost-effective manufacture in the UK to produce TEGs at a sales price of £490/kW. By achieving this, ourconsortium of research capable partners will not only safeguard TEG manufacture in the UK but will also commercialise theresults of our existing Thermo-electric research activities that are already producing globally competitive materials and processes.

对于汽车组合发动机而言，仅生产的能源的35％是有动力的，其中65％的能量实际上是“丢失”到环境中的 - 其中25％的损失能量被转移到废气中。对于非典型100hp（75kW）发动机，废热能量高达50kW。结果，汽车OEM寻求通过废气恢复来提高燃料效率 - 一种非常有吸引力的方法是使用热电动发生器（TEGS）。迄今为止，由于劳动密集型材料固化，加工和手工组装，这些方法太昂贵了。随着这些TEG的市场的增长，越来越明显的是，除非开发了自大的，具有成本效益的制造技术，否则大规模生产将出口到低成本的经济学。 PRINTEG项目将通过开发预先的自动化技术来直接解决此问题：TE粉末手和合并；表面安装的拾音器，放置和互连沉积和激光烧结。这是英国的可成本效益生产，以490英镑/kW的价格生产TEG。通过实现这一目标，研究能力的合作伙伴不仅可以保护英国的TEG生产，而且还将在其中商业化我们现有的热电学研究活动，这些研究活动已经生产了全球竞争性的材料和流程。
