Howard Cork Hayden, Emeritus Physics Professor, University of Connecticut: A generation ago, nobody considered Supercharging stations for battery-powered cars, the idea of which had been abandoned well over a century ago. The problems in 1900 were two: the batteries and the charging system. The problems in 2017 are two: the batteries and the charging system. Before the government provides more financial support to Tesla, it should examine the problems identified here with solar powered charging stations and grid powered charging stations at home. Introducing / forcing a new technology on consumers is far more than building an electric car and developing new batteries.

Semen (Sam) Dukarevich, specialist in underground cryogenic structures: This is a very short but important description of Russia and some of the former Eastern European countries. Dr. Dukarevich survived WW II as a young boy and all the years of the Soviet Union. He describes Russia today with valuable suggestions about the future.

Theodore (Ted) Rockwell retired founding partner and board member, MPR Associates, died on March 31, 2013. He was born on June 26, 1922, in Chicago and earned MS and BS degrees in chemical engineering at Princeton University. In 1960 he was awarded an honorary Sc.D. degree for contributions to the development of nuclear power. Ted was a prolific writer and speaker on technical topics, wrote popular interest articles, and established a blog, “Learning about Energy.” He edited the Reactor Shielding Manual, the fundamental reference used worldwide since its initial publication in 1956. The closing words on Ted’s life are also his own: “I like to stir up spirited discussions on important issues. Socially, I like to comfort the afflicted and afflict the comfortable.”

Van Zyl de Villiers, Past-President World Council on Isotopes, April 2018: The production and supply of key medical radioisotopes, especially molybdenum-99, but also iodine-131 and xenon-133, continue to be of major interest to the isotope industry, the healthcare community and policy makers. The main players have been very successful in improving security of supply after the shortages experienced during 2009-2010, but also underline that the present form of the 99Mo/99mTc market remains economically unsustainable.
