A HISTORY of the SOLAR CELL, in PATENTS Karthik Kumar, Ph.D
A HISTORY OF THE SOLAR CELL, IN PATENTS Karthik Kumar, Ph.D., Finnegan, Henderson, Farabow, Garrett & Dunner, LLP 901 New York Avenue, N.W., Washington, D.C. 20001 [email protected] Member, Artificial Intelligence & Other Emerging Technologies Committee Intellectual Property Owners Association 1501 M St. N.W., Suite 1150, Washington, D.C. 20005 [email protected] Introduction Solar cell technology has seen exponential growth over the last two decades. It has evolved from serving small-scale niche applications to being considered a mainstream energy source. For example, worldwide solar photovoltaic capacity had grown to 512 Gigawatts by the end of 2018 (representing 27% growth from 2017)1. In 1956, solar panels cost roughly $300 per watt. By 1975, that figure had dropped to just over $100 a watt. Today, a solar panel can cost as little as $0.50 a watt. Several countries are edging towards double-digit contribution to their electricity needs from solar technology, a trend that by most accounts is forecast to continue into the foreseeable future. This exponential adoption has been made possible by 180 years of continuing technological innovation in this industry. Aided by patent protection, this centuries-long technological innovation has steadily improved solar energy conversion efficiency while lowering volume production costs. That history is also littered with the names of some of the foremost scientists and engineers to walk this earth. In this article, we review that history, as captured in the patents filed contemporaneously with the technological innovation. 1 Wiki-Solar, Utility-scale solar in 2018: Still growing thanks to Australia and other later entrants, https://wiki-solar.org/library/public/190314_Utility-scale_solar_in_2018.pdf (Mar. -
A Plausible Resolution to Hilbert's Failed Attempt to Unify Gravitation & Electromagnetism

N., A Plausible Resolution to Hilbert’s Failed Attempt to Unify Gravitation & Electromagnetism Exploration A Plausible Resolution to Hilbert’s Failed Attempt to Unify Gravitation & Electromagnetism Victor Christianto1*, Florentin Smarandache2 & Robert N. Boyd3 1Malang Institute of Agriculture (IPM), Malang, Indonesia 2Dept. of Math. Sci., Univ. of New Mexico, Gallup, USA 3Independent Researcher, USA Abstract In this paper, we explore the reasons why Hilbert’s axiomatic program to unify gravitation theory and electromagnetism failed and outline a plausible resolution of this problem. The latter is based on Gödel’s incompleteness theorem and Newton’s aether stream model. Keywords: Unification, gravitation, electromagnetism, Hilbert, resolution. Introduction Hilbert and Einstein were in race at 1915 to develop a new gravitation theory based on covariance principle [1]. While Einstein seemed to win the race at the time, Hilbert produced two communications which show that he was ahead of Einstein in term of unification of gravitation theory and electromagnetic theory. Hilbert started with Mie’s electromagnetic theory. However, as Mie theory became completely failed, so was the Hilbert’s axiomatic program to unify those two theories [1]. Einstein might be learning from such an early failure of Hilbert to unify those theories, and years later returned to Mie theory [1]. What we would say here is that Hilbert’s axiomatic failure can be explained by virtue of Gödel’s incompleteness theorem: which says essentially that any attempt to build a consistent theory based on axiomatic foundations can be shown to be inconsistent. -

Prof. James Norman Goodier
Professor James Norman Goodier (1905 – 1969) See: https://en.wikipedia.org/wiki/James_N._Goodier Applied Mechanics Stanford University Biography from Wikipedia: James Norman Goodier (October 17, 1905 – November 5, 1969) was professor of applied mechanics at Stanford University known for his work in elasticity and plastic deformation. He was born in Preston, Lancashire, England and studied engineering at Cambridge University. He was awarded a Commonwealth Fund Fellowship which enabled him to continue his studies at the University of Michigan where he earned his doctorate in 1931 under the direction of Stephen Timoshenko with a dissertation titled Compression of Rectangular Blocks, and the Bending of Beams by Nonlinear Distributions of Bending Forces. Timoshenko moved to Stanford University in 1936 and Goodier eventually succeeded him there. He was co-author of two classic books in this field: "Theory of Elasticity," with Timoshenko, 1951; and "Elasticity and Plasticity," with P. G. Hodge, Jr., 1958 and was awarded the Timoshenko Medal by the American Society of Mechanical Engineers in 1961. He was chairman of the Applied Mechanics Division of the American Society of Mechanical Engineers 1945-46, and was elected Fellow of that Society in 1964. He had more than fifty doctoral students, one of whom was George F. Carrier. Memorial Resolution, Stanford University by Erastus H. Lee, Miklos Hetenyi and Harold C. Schmidt: Norman Goodier died on Wednesday, November 5, 1969 after a brief illness. He was born on October 17, 1905, in Preston, Lancashire, England where he attended municipal schools and won scholarships to study at Cambridge University. In 1927 he was awarded the B.A. -
