Uber and Lyft, ride-hailing apps are adding to the traffic in downtown areas of major cities in the U.S. It is getting worse to the point where cities are looking for ways to ease the congestion in downtown areas of Chicago, San Francisco, New York, New fees are being enacted in these cities on Uber and Lyft, and regulators are also considering fees. The problem is that ride sharing apps customers prefer not to pool or share rides as the ride sharing apps said they would to prevent congestion. Another problem is that Uber and Lyft are actually pulling people away from buses, subways and walking creating new waves of congestion and poor utilization of public transportation designed to ease travel for most of the post war period. Worse they are not supporting healthy living because it is harder to walk on traffic congested streets and some people become lazy and just grab a ride rather than walk a short distance or walk to public transportation. Another issue is that an estimated 40% of the time the Uber and Lyft drivers in major cities cruise around for fares without passengers. San Francisco county officials have found in a study that over 60% of the slowdown of traffic speeds in San Francisco between 2010 and 2016 was due to the introduction of ride hailing apps. In Chicago, the policy director in the mayor's office says there is exponential growth in traffic congestion from these ride hailing apps.  A December report by the California Air Resources Board found that ride- hailing cars are driving with no passengers 39% of the time, and New York city estimates cruising at 41%. Mr. Schaller, a New York City official who has studied this issue says surveys in many cities show about 60% of riders in Uber and Lyft would have walked, biked or taken public transit or stayed home if a ride hail car was'nt available. More and more so called disruption by Silicon Valley in the interest of rapid and chaotic growth is looking like a bad thing, says this report in the WSJ, creating a whole new set of problems. What is not even understood here is the vast misallocation of resources, the billions of dollars that could have improved public transportation, bike paths and other means of getting around, improvements in cities downtowns to make them friendlier and with new park spaces with those dollars invested there instead of in ride hailing apps.   ...

Boris Johnson, British prime minister has a close knit team in the new cabinet. The separate back office teams of the prime minister and the chancellor are now integrated so that there is a clear direction coming from 10 Downing Street. This was not happening when Mr. Javid was chancellor as there were wide differences on policy and compromises were being made. Mr. Javid was in the views of Mr. Johnson's team too focused on balancing the budget. Fiscal rules had to be relaxed if infrastructure promises are to be kept and action taken quickly. Mr. Johnson told his new cabinet at the first meeting- "we have to repay the trust of people who voted for us in huge numbers in December and who look forward to us delivering."

A problem the renewable energy industry faces is how to store energy so that it can meet demand when it is cloudy or calm, conditions when solar panels and wind energy generators are not working. A company in Switzerland is working on a novel solution. It uses cranes to lift 35 ton bricks that are stacked to form a 400 foot tower. When energy is needed the kinetic energy from bricks coming down powers generators.
