Bionic Silkworms Spin Fibers 6X Tougher than Kevlar

“For the first time, scientists have successfully produced full-length spider silk fibers using genetically modified silkworms. With high strength and toughness, this silk has the potential to provide a scalable, sustainable and better-quality alternative to current synthetic fibers like nylon.”

For the Time It Took to Get One Mile in 1980, You Get 2.29 Today

The time price per mile has fallen by 54 percent.

The top-selling car in 1980 was the Oldsmobile Cutlass. Gas mileage on this vehicle averaged 20 miles per gallon (17 city/23 highway). By 2023, the Honda CR-V claimed the title as the most popular two-wheel drive vehicle. The CR-V reported mileage at 31 miles per gallon (28 city/34 highway). This represents an increase of 55 percent over this 43-year period. Mileage has been increasing at a compound rate of around 1 percent a year.

Back in 1980, gasoline was selling for $1.19 per gallon, and blue-collar hourly compensation (wages and benefits) was $9.12 per hour. This indicates a time price rate of around 7.83 minutes per gallon.

Today, gasoline is selling for around $3.37 per gallon, and blue-collar hourly compensation (wages and benefits) is up to $36.50 per hour, indicating a rate of around 5.54 minutes per gallon. While the nominal price of a gallon of gasoline has increased by 183 percent, the time price has dropped by 29 percent.

But how much does it cost to travel a mile? That depends on the time price of gasoline and the car’s mileage. In 1980, at 20 miles per gallon, the time price per mile on the Cutlass would be around 23.5 seconds. By 2023, with the CR-V getting 31 miles per gallon, the time price per mile would be around 10.7 seconds. The time price per mile has decreased by 54 percent.

You can look at mileage from the perspective of how many miles you get per minute of time. The 1980 Cutlass gave you 2.55 miles per minute of your time, while the 2023 CR-V gives you 5.6 miles. Gas mileage abundance from your time perspective has increase by 119 percent. For the time it took to get one mile in 1980, you get 2.29 miles today.

There are other differences to consider. The National Automobile Dealers Association reports the price of a new Cutlass in 1980 at $6,735. At $9.12 per hour, it would take a blue-collar worker 738 hours to own this new car. Honda listed the 2023 CR-V for $28,410. At $36.50 per hour, it would take the blue-collar worker 778 hours to buy one. So, while the time price of the top-selling car has increased by 5 percent, the mileage, safety, reliability, and comfort have all increased by much more.

Yes, nominal gas prices are higher than 1980, but it’s not the money that counts; it’s your time. Time prices are the true prices.

Alexandria Ends Single-Family-Only Zoning

“Alexandria lawmakers voted unanimously early Wednesday to eliminate single-family-only zoning in this Northern Virginia city, a functionally limited but symbolic and controversial move that opens the door for the construction of buildings with as many as four units in any residential neighborhood.”

Battery Maker Develops Futuristic Cobalt-Free Cell for Electric Cars

“Swedish battery maker Northvolt AB has developed its first sodium-ion product, a technology that could cut reliance on scarce raw materials and lay the foundation for the company’s next generation of electric-car batteries.

The cell has a ‘best-in-class’ energy density of more than 160 watt-hours per kilogram, and was made without any lithium, nickel, cobalt or graphite, the company said Tuesday. While the first sodium-ion cells are designed primarily for energy storage, coming generations may be able to deliver higher energy density for electric mobility.”

The Race to the Sky: How Competition Pushes Humanity Forward

Cities could still be growing quickly upward, but regulations are limiting their growth.

“I would give the greatest sunset in the world for one sight of New York’s skyline.”

—Ayn Rand, The Fountainhead

The story of how the Empire State Building came to dominate Manhattan’s skyline—defeating 40 Wall Street and the Chrysler Building for the title of the tallest building in the world—is an illustration of the power of competition and innovation.

In 1929, the successful businessman George Ohrstrom hired architect H. Craig Severance to design 40 Wall Street. Severance was a well-known architect in New York City and together with William van Alen had built amazing constructions, such as the Bainbridge Building on W. 57th Street and the Prudence Building at 331 Madison Avenue. Van Alen was an innovator and a revolutionary who often challenged the classical and Renaissance styles that had influenced most American cities since the beginning of the 20th century. He often ran into problems with clients who rejected his modern styles. Severance, worried about losing clients, decided that he no longer needed Van Alen’s partnership, and they ended their business relationship in 1924. In 1929, Walter Chrysler hired Van Alen to design a monument to his name, the Chrysler Building.

Competition Incentivized Innovation

In April 1929, Severance learned that his former partner was designing a structure of 809 feet. Ohrstrom and Severance, worried about falling behind, announced that they would add two additional floors to their original design so that 40 Wall Street would end up with a total height of 840 feet. That same year, Empire State Inc., led by former General Motors executive John Jakob Raskob, entered the race—putting pressure on Severance and Van Alen. To keep pace with the other two projects, architectural firm Shreve, Lamb & Harmon and builders Starrett Brothers & Eken accelerated the construction process. According to architectural historian Carol Willis, the framework of the Empire State Building rose four and a half stories per week due to an A-team design approach in which architects, builders, and engineers collaborated closely with each other.

Troubled by both Severance and the Empire State project, Van Alen designed the famous chrome-steel art deco crown for the top of the Chrysler Building and a sphere to stand on top of the crown. The sphere was built inside the crown, hidden from the public, and it was never announced to the press or explicitly mentioned. On the other hand, Severance modified his design one more time and asked permission to add a lantern and a flagpole at the top of the tower, increasing the height by 50 feet. Severance planned to have 40 Wall Street reach the 900-foot mark to secure its place as the tallest building in the world.

On October 23, 1929, the sphere of the Chrysler Building was lifted from the inside of the crown, reaching 1,046 feet and surpassing the final height of 927 feet of 40 Wall Street. The crash of Wall Street on October 28 distracted the press from the trick played by Van Alen, and it was not reported immediately. When Severance found out, it was too late to change his design—40 Wall Street held the title for one month from its opening in the first week of May 1930 to the opening of the Chrysler Building on May 27. The Chrysler Building held the title for only 11 months until the Empire State Building was completed in 1931 and became the new tallest building.

Regulations Limit Us

The Empire State Building held the title of tallest building in the world for 40 years, and it was built in only one year and 45 days. Bryan Caplan, professor of economics at George Mason University, believes that excessive restrictions slow construction today. Regulations such as height restrictions prevent cities from going up. Humanity now has better technology than in the time of New York’s race to the sky, but getting permits to build upward is extremely difficult. Excessive restrictions also generate artificial scarcity, which is slowing the growth of cities and making it difficult (and expensive) to live in them. Cities could grow upward, but regulations limit their growth.

However, we continue to see competition in many industries; technology companies fighting for the dominance of artificial intelligence are creating better and more efficient tools. The race between SpaceX, Blue Origin, and Virgin Galactic is improving the development of innovative technologies. Soon we might even have commercial flights to the moon. History has shown that when brilliant minds have freedom to compete, humanity moves forward.
