Engineers are designing quieter streets by adding rubber “crumbs”, reclaimed from shredded tires, to the bitumen and crushed stone used to make asphalt.
Enough tires are recycled in America each year to produce 20,000 lane-miles of road pavement mix, enough to re-pave about 0.5% of America's roads, according to Liberty Tire Recycling, a Pittsburgh firm that handles around a third of America's recycled tires.(1)
It is now possible to make rubberized asphalt less expensively than the traditional sort because rubber can partially replace bitumen, the binding agent used to hold the crushed stones together in ordinary asphalt. Bitumen is derived from oil, which means its price has risen over the past decade alongside that of crude oil. (1)
Discarded tires are cheap and are likely to get cheaper. In rich countries, around one tire is thrown away per person per year. (1)
In Hawaii we burn tires at the AES coal plant. This is much better than dumping them in a landfill or wasting fuel to send them out of state. But we should be making new roads with them.

Honolulu Rail Forecast 2 to 4 Times Higher than Actual Systems
The City estimates that TheRail will have a ridership of 116,000 (boardings) in 2030, about 10 years after the system is supposedly completed.
While TheRail is actually a fully elevated, steel-wheel-on-steel-rail heavy rail system, it is designed to fail by combining two poor choices:
(1) It is fully elevated which means it costs well over 5 times the typical light rail system.
(2) It does not use large, heavy rail style, high capacity trains, but smallish light rail trains.
These two choices make it a high cost and low capacity system.
Because of its low capacity, it is comparable to existing light rail systems. The table below includes all US light rail systems that (a) may be characterized as "modern" by having been developed after 1980, and (b) are over 8 miles of length. This comes to 11 comparable systems with route miles ranging from approximately 10 to 42 miles.
The average daily boardings of these 11 existing systems is 38,852 and the average route miles is 28. This yields 1,536 daily boardings per mile or 1,500 boardings per mile for a round number. (Remember we are talking about year 2030 and roughly 20% of TheRail’s users have not been borne yet.)
When one looks at statistics, it is advisable to remove the highest and lowest values and re-check the averages. By doing so for daily boardings and route miles, systems 3, 6 and 9 drop out. The resulting average daily boardings of the eight systems is 37,822 and the average route miles is 27. This yields 1,528 daily boardings per mile. This again rounds to 1,500 so this estimate is quite robust.
Using this estimate of 1,500 times the 20 miles of TheRail yields 30,000 daily boardings. Now let's give a huge break to Honolulu because of the H-1/H-2 congestion, the high cost of living and the higher average density (although high density does not apply west of Middle Street): Let's double this estimate to 60,000 boardings. This will be the likely maximum boardings of TheRail.
What's the City's estimate that FTA approved? 116,000 daily boardings, which is laughable.
Both Parsons Brinkerhoff and FTA received dozens of eggs on their face for the island heavy rail Tren Urbano in San Juan, Puerto Rico where they estimated 80,000 boardings on the opening year and they got 25,000 in 2006.
There is no lesson for PB, FTA and HART to learn. There is no accountability or penalties. They are all dedicated promoters of TheRail. Honolulu's ridership estimates simply prove that history (and unabashed deception) simply repeats itself.

Honolulu Rail Cost Escalation
It is important to understand how much costs escalate in megaprojects. All these costs in bond-financed public projects are to be borne by the taxpayer. Oahu has fewer than 400,000 taxpayers so the possibility of a twelve billion dollar bill for a long rail line presents a staggering liability. Over $30,000 per taxpayer.
In 2005 Mayor Mufi Hanneman and his supporters went to the Legislature and asked for a temporary (20 year) 1% tack on to Hawaii's 4% general excise tax in order to develop a large rail system for an approximate cost of $2.7 Billion. The Legislature approved a 0.5% tack on to the GET in hopes that Federal Transit Administration and other taxes will cover the total. Here is the letter to The Honolulu Advertiser by Mayor Mufi Hannemann promising that the 20 mile system will cost $3 Billion.
In 2008 General Elections there was a City Charter Amendment asking the city to install a steel on steel fixed guideway system. The cost of the 20 mile system had grown to $4.6 billion and almost $1 Billion was the contingency funds. TheBus funds were not touched in 2008.
In 2010 outgoing governor Lingle procured a financial analysis report for the rail that she had supported, in light of the escalating costs of rail and the 2008-2009 fiscal crisis. IDG, a reputable financial and risk analysis consultant based in Washington, D.C., estimated that the 20 mile cost will be more likely $7.2 Billion.
Despite these facts, Governor Abercrombie signed off on the State EIS and Mayor Carlisle dismissed the financial report as "an anti-rail tirade."
In summer 2012 the City submitted its final application to the FTA for a Full Funding Agreement. In it, the cost of the 20 mile line has grown further to $5.17 Billion but contingencies have been reduced to about $600 Million and another $150 Million is "borrowed" from TheBus fleet funds. In other words, the 2012 cost estimate would be $5.7 Billion if they did not fudge the amounts and kept them at the 2008 level.
In May 2012 Councilmember Kobayashi asked HART to estimate the cost of the full 34 mile system from West Kapolei to the UH and Waikiki. HART's response was $9.03 Billion.
If we apply IDG's cost escalation of the 20 mile system to the 34 mile system we get $12.6 Billion. Hanneman's rail has ballooned from $3.6 Billion to $12.6 Billion!
Rail was a bad idea at a cost of $3 Billion. Now that the likely cost is three times higher, the choice is clear. People have made their choice quite clear by handing both mayors Hannemann and Carlisle their walking papers.

Honolulu Rail on Trial
Malia Zimmerman interviews Professors Randy Roth (law) and Panos Prevedouros (engineering). In this video filmed on O'lelo's Palolo studio a week ago, Professor Roth correctly predicts the outcome of the State Supreme Court. See below.
Congratulations to Paulette Kaleikini and her native Hawaiian hui for scoring this legal victory: Rail Construction Shouldn’t Have Started, Hawaii Supreme Court Rules. In other words, Mayor Carlisle and HART clearly broke the law.
Ninth Circuit Court Judge Teshima heard the Federal Lawsuit against Honolulu rail. Listen to the YouTube above where I indicate how the attorney for FACE clearly lied to the judge. Professor Roth expects that this lawsuit will also be successful. Decision expected in a couple months.

TECHNOLOGY and INNOVATION Survey -- The Economist and Hawaii Results
TECHNOLOGY Results (click to take the survey, part 1, and technology survey part 2.)
The results are summarized in the Table and discussed below.
The original debate questions in The Economist address various issues relating to technology. Ten questions were selected and International and Hawaii responses are compared.
For the first four issues, both The Economist and Hawaii respondents agree. For the next two issues either International or Hawaii responses are neutral, and for the last four issues the opinions are clearly opposite.
Both Hawaii (80%) and international response (62%) disagrees with the position that genetically modified crops and sustainable agriculture are complementary. Both agree that the Internet is making journalism better and that we are now in a new tech bubble. More international respondents (61%) than Hawaii respondents (56%) agreed that social networking technologies will bring positive changes to education.
Economist respondents want NASA to send astronauts to the moon but Hawaii is clearly ambivalent on this. Hawaii respondents believe that innovation works best when government does least but The Economist habitual government subsidy readers overwhelmingly place government at the center of innovation (84%). It does not take a genius to know who's right. Just think about the last time that a PC, smartphone or search engine was invented in Europe...
Hawaii respondents clearly agree (81%) that if the promise of technology is to simplify our lives it is failing, but The Economist respondents mildly (53%) believe that technology has simplified our lives. Technology has simplified my life. As an engineer and researcher, the Internet and digital scholar tools have cut down by annual time spent at the university library from 1 to 2 weeks a year in the late 1980s to less than two hours per year after 2000.
Exact opposite responses to the argument that the continuing introduction of new technologies and new media adds little to the quality of education: 56% of international respondents disagree and 57% of Hawaii respondents agree. In other words, Hawaii respondents believe that technology doesn't do much for education. Maybe that's a generic response because public education in Hawaii produces poor outcomes. Or, perhaps in Hawaii we buy a lot of technology for schools but don't use it in an effective and exciting manner. (However, that's not the case at Liholiho Elementary that my 5th grader attends since kindergarten.)
Underutilized technology is certainly the case with intelligent transportation systems (ITS) on our highways. Hawaii has spent upwards of $500 million on ITS and signal infrastructure since 2000. Yet traffic signals still operate mostly like Christmas lights and, like Chicago in the 1970s, we get our traffic conditions from ... Jason Josuda on FM radio. In 1994 I bought a Saab 900 with a Radio Data System. The car could show on the dash messages about road conditions. It was disabled for the US and if I still had it, it could be useless in Hawaii in 2012.
Hawaii respondents got the next one right: 65% agree that we're on a post-PC era, and that smartphones and tablets will soon dominate. No question that this will be so by 2020 in most of the US. Only 28% of international respondents agreed to this. Much lower disposable income (due to lower incomes and higher taxes) do not allow Europeans to change technology items frequently.
Finally from President Obama, to Linda Lingle and many luminaries in the between, math and science education is the best way to stimulate future innovation. Correctly, 74% of international respondents agreed but only 33% of Hawaii respondents agree. Sun, surf and R&R does not jibe with STEM (science, technology, engineering and math!)
