Thermoelectric Generator for Internal Combustion Engines

A passive, thermoelectric generator that could decrease battery size by 25% saving both cost and weight for vehicles, helicopters, etc. Possibly a big winner...

"The researchers tested their prototype in a laboratory and found that with a change in temperature of 190 degrees, their thermoelectric generator produced 40 watts of power, enough to charge a phone or a few LED lights and act as a supplementary source of energy for a vehicle’s battery.... It converted about 15% of exhaust heat into electricity. Other commercial thermoelectric generators typically convert about 6% to 8% of heat into additional electricity."

  Nimitz lane closures intensify evacuation gridlock worries Victoria Budiono, The Honolulu Star-Advertiser Sun, August 31, 2025 at 9:06 AM PDT The lane closures on Nimitz Highway through 2030 for Honolulu rail construction are raising concerns not only about daily traffic but also about how the city will move people in the next evacuation emergency in the aftermath of last month’s tsunami-scare gridlock. On Aug. 18, the Honolulu Authority for Rapid Transportation and contractor Tutor Perini Corp. began 24 /7 closures on Nimitz between Awa and Bishop streets. One lane in each direction along the center median is shut for the City Center Guideway and Stations project, leaving three lanes open each way. The work will affect thousands of commuters, pedestrians and businesses for years. Retired University of Hawaii engineering professor Panos Prevedouros warned that the lane closures could be especially dangerous during an evacuation, pointing to the July 29 tsunami scare when some mo...

WalletHub's Best and Worst States to Drive 2026

  I was quoted in WalletHub's Best and Worst States to Drive 2026. What tips do you have for a person looking to keep the costs of car ownership low? Those looking for a new or replacement car need to research their next purchase. Sources like Edmund’s and Consumer Reports are free of hype and provide reliable data on vehicle features, performance, long-term costs, and mpg. Buyers should visit a dealer well informed and always test a few comparable models before committing to a purchase. They should ignore the so called “dealer pressure”. If they already own an expensive vehicle to run, then they can consider a swap with a low running cost model at a dealer, Carvana, etc. Typically, hybrids are more economical and many used EVs are on the market at a fairly low price. Gasoline affinity programs can save several cents per gallon. Research local websites and find reliable independent car repair shops; obtain at least two quotes for an expensive maintenance and/or part replacement job...

Best & Worst States for Teen Drivers (2025)

Provided input to several questions for  WalletHub's advisory article  on Teen Drivers which was also covered by several radio stations as well as NewsWeek  and MSN . What tips do you have for parents of teen drivers? There is no rush for teenagers to drive. If they do not show sufficient maturity at home and at school, placing them on the road in the driver’s seat, unsupervised, is an accident waiting to happen. In states with graduated licensing schemes, this risk is reduced. Strongly recommended is a hands-on safety course such as Street Survival, Driver’s Edge and similar programs. Search “teenager safety driving school” to find programs in your vicinity. I am a Street Survival instructor and my teenager took the Saturday full day course twice. Teenagers finish the day with several tools for dealing with emergency situations while driving, and more humbled about their (inflated) driving abilities. What is the biggest risk that teen drivers face? The crash risk of teen...
