Auto Industry
• Expected to be largest TEG market in next 10 years
• Initial use in heavy trucks
• Multiple hurdles:– Impact on weight, performance, cost– ZT performance not only concern
“Heat sink technology developments and system design may be as important and possibly more important than the material developments”-Hylan B. Lyon Ph.D., CFO, Marlow Industries

Waste Heat Recovery
• Does not utilize all of the benefits of TEGS– However, alternatives
perform poorly at low delta-T
• Requires very large scale inexpensive systems 500 watt waste heat TEG
(used on back of incinerator)

Summary
• Significant improvements in materials• Research and funding momentum• Expect ~2.0 ZT, high volume production, <
$0.3/watt for TE modules by 2010
Other opportunities/hurdles:• Need for improvements in other parts of system
– Heat exchangers, electronic controllers, packaging, design systems…
– Will be critical to cost effectiveness of TEG’s
