The ProblemThe ProblemIt takes nearly 15 years to recoup the extra investment in hybrid cars! *

Who would want to make this commitment?

It takes nearly 15 years to recoup the extra investment in hybrid cars! *

Who would want to make this commitment?

*Based on calculations comparing the Honda Civic to the Honda Civic Hybrid

Value PropositionValue PropositionTo make hybrid cars more cost

effective by improving their fuel efficiency by up to 25%

How?◦By recovering waste energy!◦Over 60% of the energy used by a

combustion engine is wasted as heat.Technology:

◦ Rough Thermoelectric Silicon Nanowires

How It WorksHow It Works

Value ChainValue Chain

While we must target car manufacturers to implement the technology, our product ultimately benefits the consumer, who saves money on gas!

Market AnalysisMarket Analysis

“We see the hybrid unit continuing to grow to over 1 million units by 2012 so long as gas prices grow.” -Michael Omotoso, senior manager of J.D. Power.

Money Savings!Money Savings!

With the thermoelectric silicon nanowires, consumers enjoy a ~25% increase on their mileage and can expect to save an extra ~$150 per year!
