Porsches in my Addresses

Four addresses were I spent 30 years of my life had.... Porsches in them!

State to Look at Building Parking for Laniakea Beach Park

UH Civil Engineering Professor Panos Prevedouros said he and his student recently looked at the pedestrian and traffic patterns near Laniakea Beach. He said every hour, there’s an average of “1,000 vehicles, 300 pedestrians.” “No sidewalks, no signs, no nothing. That’s why this area has been a problem for safety and congestion for many, many years,” he said.“No sidewalks, no signs, no nothing. That’s why this area has been a problem for safety and congestion for many, many years.” Prevedouros said he supports any solutions — long-term or short. “I understand it takes a long time to install long time measures but it’s already been a long time and they’re mired in their paperwork," he said. We need to keep the heat on this subject!

Wallet Hub: Cheap Car Insurance in 2019

Quoted in WalletHub.com analysis of car insurance.

Why do car insurance rates (and even providers) vary so much from state to state?

Mostly due to legal definitions of tort and liability as well as minimum required coverage.

Is it riskier to drive in some cities and states than others? Are the drivers themselves riskier?

Specific age groups and race groups have shown increased rates for one or several types of crashes. Some of these groups are over-represented in some states. Also very busy intersections, substandard freeway merges and high volume rural and mountainous roads have a higher incidence of crashes. The number of these "black spots" also varies by city and state. Weather creates variability in crashes too, i.e., there are more crashes in foggy and icy conditions; there are many states that do not have these conditions.

Is there anything that state and local governments do to promote cheap car insurance rates for their constituents?

Enact properly designed and enforced laws on speed, red light running, helmet usage, intoxication, etc. These vary widely from state to state and sometimes within a state.

Some Ways To Stop The Exodus To The Mainland

Quoted in an article on an important subject covered by Dan De Gracia.

Panos Prevedouros, chairman of the UH Civil and Environmental Engineering Department, says four dimensions are vital to retaining young people in Hawaii: “satisfying, well paying jobs; quality of infrastructure and built environment; housing availability and price; and the cost of living.”

I do have a few specific suggestions for the four items I mentioned to Dan, as follows:

1. Satisfying, well paying jobs... There is plenty good news here. Not only we have the lowest unemployment in the nation, but by 2020 the baby boomer retirement will become stronger. Engineers, business majors and other professionals will fare very well in job selection and remuneration.
2. Quality of infrastructure and built environment... This will remain a weakness as the state and city grapple with human centered issues (homeless and elder care), bad choices (rail and misguided energy endeavors) and generous promises (civil service employee retirement and health care) which leave very little left over for infrastructure improvements. Parenthetically, this is why I am no longer interested in running for executive office in Hawaii. My ability to deliver on these fundamental quality of life assets of society will be useless.
3. Housing availability and price... Leadership is needed to develop the remainder a Kakaako not as real estate safety deposit boxes for foreigners but as vibrant community for young (under 35) and old (over 65) with a fifty year P3, public private partnership, to develop reasonably priced rentals for unmarried young adults and for seniors in apartments with 1 and 2 bedrooms priced at, say, $1,200 and $1,600, respectively, with only 0.5 parking stall per apartment rented at $100 per month, plus incentives for transit and bicycle use. Three-four phases of about 500 units each will make a huge impact, and the amount of subsidy will be modest. The P3 is necessary to ensure quick, high quality development of the units and continuous maintenance for the life of the 50 year agreement; we do not want this done as a public housing project but as a long term for profit development with some taxpayer subsidy.
4. Cost of living... The subsidized apartments described in (3) above, in combination with adoption of non motorized transportation for short trips and car-sharing for longer ones, will allow the young to partly defeat Hawaii's high cost of living for a decade or more. Combined with a good income from the start, the young will be able to save enough to afford a house or large unit for developing a family and making Hawaii their forever home.

However, our politicians pay no attention and clearly have no sympathy for young adults making, say, $50,000 a year or more, who are contemplating the choice to stay in Hawaii, and barely make it, or leave Hawaii for better opportunities. They are busy with their liberal kuleana: Taxation, land control, environmental control, more control and regulation, the homeless, the poor, the "living wage" and the like. This tells us a lot about priorities and the future of Hawaii... For decades now, the young ones have heard this message loud and clear.

Self-Driving Cars Another Nail In Rail’s Coffin

Quoted in the article "Self-Driving Cars Another Nail In Rail’s Coffin "by Josh Mason

Panos Prevedouros, chairman of the UH civil and environmental engineering department, said at a Grassroot Institute of Hawaii panel on May 3 that the rail system is already obsolete because the share of public transit nationwide has already halved over the past few years that Uber and Lyft have grown exponentially.

Energy Revolution Won't Come from Renewables

Well stated reality check in Want an Energy Revolution?

"For a practical example of the physics-anchored gap between aspiration and reality, consider Florida Power & Light’s recently announced plan to replace an old gas-fired power station with the world’s biggest battery... this battery “farm” will be able to store just two minutes of Florida’s electricity needs. That’s not going to change the world, or even Florida."

Vinod Koshla (of Sun Microsystems fame) had a similar opinion in 2011: "Environmentalists are fiddling while Rome burns. Forget today’s green technologies like electric cars, wind turbines, solar cells and smart grids. None meets what Khosla calls the “Chindia price”—the price at which people in China and India will buy them without a subsidy. “Everything’s a toy until it reaches that point.” (The Economist, March 10, 2011)

How Clean Is Your Electric Vehicle?

The correct answer is... it depends on the way that power is produced. For example, EVs are not very clean in Honolulu (top graph); hybrids do better. But Reno (bottom graph) has natural gas, geothermal and solar power production, so EVs there run much cleaner.

Feels Good to Be Ahead of Fellow Researchers

This 2019 paper concluded as follows:

"HEVs are rapidly emerging as a potential alternative to the existing state of transportation due to their lower petroleum consumption and toxic emission. Strict CO2 emission laws and increased public awareness will propel HEVs to be the future of road transportation." (Singh, K.V., Bansal, H.O. & Singh, D. J. Mod. Transport, Springer (2019) 27: 77, doi.org/10.1007/s40534-019-0184-3)

We reached a similar conclusion and for the same reasons four years earlier!

The HEV has the second lowest societal and consumer LCC compared with all other six vehicle types. Its ranking makes it a strong candidate as a transitional technology. Its low LCC resulted from the low emission impact cost, the improved fuel efficiency and the low manufacturing cost. In the short term, there are no barriers that should be overcome to increase the penetration of HEV in the market.  (Mitropoulos, L. and P. D.
