AFFILIATION:   Impulse Technology LLC, State College, Pennsylvania, United States

TECHNOLOGY SUMMARY

Track: Energy & Resilience
Area: Energy Storage
Tech Readiness: TRL 6

Tech Brief: A cost-effective, heatsink-free thermal harvester that is more efficient and less costly than currently available products, can power wireless sensor networks and internet of things, extend battery life and/or replace batteries altogether.

FIGURES OF MERIT

Value Proposition: Our “patent pending” unique geometry/design of thermal harvester: (i) provides 3-5 times more heat to electricity conversion efficiency, producing more useful power, (ii) is cost effective --reduces $/watt cost by 3 times through automated and low cost manufacturing, (iii) sustainable--efficiency comparable to other engines such as car engines, (iv) no additional extra cooling system is needed---saves money and feasible for space limited applications, and (v) environment-friendly green technology. For specific application in Wireless Sensor Network: For a 20-year life-cycle of 50 nodes of WSN (i) Cost: Impulse TE --- one time =$7,000 ((>$18*50)+ heatsink ($123*50)), Marlow >$7,000 ((>$25*50)+ heatsink (~$120*50)) (ii) Space: Impulse TE---2cm x 2cm x 0.5cm, compared to the relatively large space needed for 4 AA alk batteries (approx. 5cm x 2.8cm x 2.8cm) and conventional TE’s relatively very large heatsink (on average >>>5cm x 2.8cm x 2.8cm).
