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."

Price Inflation in the US: My Family’s Basket of Goods from COSTCO

Image
[ Part 1: COSTCO – Part 2: AMAZON] In summer 2018, my family and I went on a trip to the Reno-Tahoe area, mostly for vacation but also to get an idea if the greater Reno area may be a suitable one for relocating from Honolulu, after my retirement from the University of Hawaii. During the visit, I took pictures at Reno Costco of some of the products and items we used to buy at the time in Honolulu. I wanted to compare them with Honolulu’s Costco (at Iwilei). I was expecting that the “price of paradise” would hit again, and many items would be more expensive in Hawaii. I was planning to blog about it. Much to my surprise, the prices were basically the same … nothing to write about. Fast forward to 2024 and the “big news” is inflation and the cost of food items. Actually, most of the inflation occurred soon after the Covid pandemic was under control. The rise in prices was due to high demand and limited supply because of labor shortages and supply chain issues in the harbors, etc. Food i...

Global Trends 2025

Image
  Back in 2008, the US National Intelligence Council published Global Trends 2025, A Transformed World , a 100 page report translated in several languages an debated in many governmental proceedings and conferences. The report included sections on climate change and sustainability. I presented those in my CEE 444 course on infrastructure sustainability and resilience. I recently stumbled upon this report and took another look at it because it is now 2025. How much did they get right? What did they get wrong? I provide answers for four major areas of the report: geopolitics, energy, climate and destabilizing factors. On the geopolitical front they focused on BRICs… Brazil, Russia, India and China. They expected a bigger role of Brazil. But their contentious politics did not let Brazil shine. They did not expect Russia to become more demographic or technologically important. They got it right, but they did not focus on their cybersecurity advancement and threat. They expected that ca...
