These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to analyze how electric vehicles will become economic feasible if the right design decisions are made to benefit from the falling costs of electronics. One key decision is the use of micro-grids to enable direct charging of the batteries, which is more efficient. A second key decision is the number of recharging stations and thus the frequency by which users can recharge their vehicles. More frequent recharging means smaller batteries can be used and thus the slow rate of improvements for energy storage densities can be overcome. A third key decision is wired vs. wireless charging. Wireless charging eliminates the time consuming maintenance and fitting problems of wires and thus enables faster hookups. It also benefits from the rapidly falling cost of electronics; the falling cost of ICs, power electronics, and thin-film coils means that wireless charging is likely to become economically feasible in the near future and allow the problem of low energy storage densities of batteries to be solved.
Wireless charging using electromagnetic induction, and resonance magnetic coupling. Effects and limitations, cheallenges faced and meathods to overcome. Success Case study. References included.
Now a days world is shifting towards electrified mobility to reduce the pollutant emissions caused by nonrenewable fossil fueled vehicles and to provide the alternative to pricey fuel for transportation. But for electric vehicles, traveling range and charging process are the two major issues affecting it’s adoption over conventional vehicles.
With the introduction of Wire charging technology, no more waiting at charging stations for hours, now get your vehicle charged by just parking it on parking spot or by parking at your garage or even while driving you can charge your electric vehicle. As of now, we are very much familiar with wireless transmission of data, audio and video signals so why can’t we transfer power over the Air.

The electricity supply industry is undergoing a profound transformation worldwide. Market forces, scarcer natural resources, and an ever-increasing demand for electricity are some of the drivers responsible for such unprecedented change. Against this background of rapid evolution, the expansion programs of many utilities are being thwarted by a variety of well-founded, environment, land-use, and regulatory pressures that prevent the licensing and building of new transmission lines and electricity generating plants.

This slide presents an introduction to microgrid. This is the second class for the subject 'Distribution Generation and Smart Grid'. Class wise I will provide all the discussions and analysis.
Vehicle to grid ( V2G) technology ca n be defined as a system in which there is a capabilty to control, bi-directional flow of electric energy between a vehicle and the electrical grid. The integration of electric vehicles into the power grid is called the vehicle-to-grid system.

Distributed energy units cannot be directly integrated into the power grid due to their inherently varying output. An interfacing technology is required. The power electronic interface is used for connecting distributed energy resources to the smart grid. It can also be used in any type of electric vehicles. It does not store energy in its circuitry. It receives power from the distributed energy source and converts it to power at the required voltage and frequency. This paper provides a brief introduction on power electronic interface. Matthew N.

MicroGrid and Energy Storage System COMPLETE DETAILS NEW PPT Abin Baby
A microgrid is a localized grouping of electricity generation, energy storage, and loads that normally operates connected to a traditional centralized grid (macrogrid). This single point of common coupling with the macrogrid can be disconnected. The microgrid can then function autonomously. Generation and loads in a microgrid are usually interconnected at low voltage. From the point of view of the grid operator, a connected microgrid can be controlled as if it were one entity.
Microgrid generation resources can include fuel cells, wind, solar, or other energy sources. The multiple dispersed generation sources and ability to isolate the microgrid from a larger network would provide highly reliable electric power. Produced heat from generation sources such as micro turbines could be used for local process heating or space heating, allowing flexible trade off between the needs for heat and electric power.
In this project, main focus is to develop high power density and high efficiency converter with closed loop control for attaining load and line regulation. Complete converter was simulated in PSIM and implemented hardware in CEERI lab.
These slides presents on introduction to energy storage devices. Later of the class the modelling and control aspects are also going to be presented in some other slides.
A solar inverter, or PV inverter, converts the direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-line electrical network.

Solving Energy Storage Challenges Offshore - Offshore Europe 2017 Cinema Seminar - Dr. David Blood, Parker Hannifin
Energy storage is big news, following the UK government’s announcement to establish a center for battery research and plans to reduce or shift electricity use to creating a smarter, more flexible energy system.
Moving rig-based diesel gen sets to a new hybrid technology might sound like a step too far. But using battery storage alongside existing power systems is not a huge leap, with the potential to reduce fuel, operations and maintenance costs, whilst improving power quality.
This technical seminar for oil and gas professionals was run by Parker at Offshore Europe 2017. It covers the potential applications and benefits of energy storage, an overview of micro-grids and how to overcome potential challenges. The presentation also features some case study examples.

The "Unproductive Bubble:" Unprofitable startups, small markets for new digit...Jeffrey Funk
This article will show that the current bubble has produced few profitable startups and involved few if any new digital technologies, nor technologies involving recent scientific advances, and thus it is unlikely that much that is productive will be left once the dust settles. There is a growth in old technologies such as e-commerce but little in new technologies such as AI. The startup losses are also much larger than in the past suggesting that fewer of today’s startups will still exist in a few years than those of 20 years ago.
Commercialization of Science: What has changed and what can be done to revit...Jeffrey Funk
This paper several changes that I believe may have reduced America’s ability to develop science-based technologies. I make no claims about the completeness. I begin with the growth of university research and then cover several changes it engendered, including an obsession with papers, hyper-specialization of researchers, and huge bureaucracies, also using the words of Nobel Laureates and other scientists to make my points.
2000, 2008, 2022: It is hard to avoid the parallels How Big Will the 2022 S...Jeffrey Funk
These slides summarize the recent share price declines for new startups, declines that are driven by huge annual and cumulative losses and it contrasts today's bubble with those of 2000 and 2008. It shows that today's bubble involves bigger startup losses than those of the 2000 bubble and that the markets of new technologies have not grown to the extent that those of past decades did. Many hedge funds, VCs, and pension funds are heavily invested in these startups. Some of them are also highly leveraged.
The Slow Growth of AI: The State of AI and Its ApplicationsJeffrey Funk
The failure of IBM Watson, disappointments of self-driving vehicles, slow diffusion of medical imaging, small markets for AI software, and scorching criticisms of Google’s research papers provide evidence for hype and disappointment in AI, which is consistent with negative social impact of Big Data and AI algorithms. There are some successes, but they are much smaller than the predictions, with virtual applications (advertising, news, retail sales, finance and e-commerce) having the largest success, building from previous Big Data usage in the past. Looking forward, AI will augment not replace workers just as past technologies did on farms, factories, and offices. Robotic process automation and natural language processing are likely to play important roles in this augmentation with RPA automating repetitive work, natural language processing summarizing information, and RPA also putting the information in the right bins for engineers, accountants, researchers, journalists, and lawyers. Big challenges include reductions in training time depending on faster computers, exponentially rising demands on computers for high accuracies in image recognition, a slowdown in supercomputer improvements, datasets riddled with errors, and reproducibility problems.

Smaller than expected markets, money-losing startups, failure of Watson, slow-diffusion of self-driving vehicles and medical imaging, and scorching criticisms of Google’s research papers are some of the examples used to characterize the hype of AI. There are some successes, but they are much smaller than the predictions, with advertising, news, and e-commerce having the biggest success stories. Looking forward, #AI will augment not replace workers just as past technologies did on farms, factories, and offices. Robotic process automation and natural language processing are likely to play important roles in this augmentation with #RPA automating repetitive work, natural language processing categorizing information, and RPA also putting the information in the right bins for engineers, accountants, researchers, journalists, and lawyers. The big challenges include exponentially rising demands on computers for high accuracies in images, a slowdown in supercomputer improvements, datasets riddled with errors, and reproducibility problems.

The Troubled Future of Startups and Innovation: Webinar for London FuturistsJeffrey Funk
These slides show how the most successful startups of today (Unicorns) are not doing as well as the most successful of 20 to 50 years ago. Today's startups are doing worse in terms of time to profitability and time to top 100 market capitalization status. Only one Unicorn founded since 2000 has achieved top 100 market capitalization status while six, nine, and eight from the 70s, 80s, and 90s did so. It is also unlikely that few or any of today's Unicorns will achieve this status because their market capitalizations are too low, share prices increases since IPO are too small, and profits remain elusive. Only 14 of 45 had share price increases greater than the Nasdaq and only 6 of 45 had profits in 2019. The reasons for the worse performance of today's Unicorns than those of 20 to 50 years ago include no breakthrough technologies, hyper-growth strategies, and the targeting of regulated industries. The slides conclude with speculations on why few breakthrough technologies, including science-based technologies from universities are emerging. We need to think back to the division of labor that existed a half a century ago.
Where are the Next Googles and Amazons? They should be here by nowJeffrey Funk
Great startups aren’t being founded like they were in the 1970s (Microsoft, Apple, Oracle, Genentech, Home Depot, EMC), 1980s (Cisco, Dell, Adobe, Qualcomm, Amgen, Gilead Sciences), and 1990s (Amazon, Google, Netflix, Salesforce.com, PayPal). All of these startups reached the top 100 for market capitalization, but Facebook is the only startup founded since 2000 which has entered the top 100. Tesla and Uber are often discussed as highly successful but they have many times higher cumulative losses than did Amazon at its time of peak losses and neither has had a profitable year despite being older than Amazon was when it achieved profits. Furthermore, few of the recent Unicorn IPOs have experienced shareprice increases greater than those of the Nasdaq (14 of 45), only 3 of these 14 have profits, and only six of them have a
market capitalization over $30 (Zoom), $20 (Square), and $10 billion (Twilio, DocuSign, Okta). America’s venture capital system isn’t working as well as it once did, and the coronavirus will make things worse before the VC system gets better.
Start-up losses are mounting and innovation is slowing, but venture capitalists, entrepreneurs, consultants, university researchers, and business schools are hyping new technologies more than ever before. This hype is facilitated by changes in online media, including the rise of social media. This paper describes how the professional incentives of experts and the changes in online media have increased hype and how this hype makes it harder for policy makers, managers, scientists, engineers, professors, and students to understand new technologies and make good decisions. We need less hype and more level-headed economic analysis and this paper describes how this economic analysis can be done.

Irrational Exuberance: A Tech Crash is ComingJeffrey Funk
These slides apply Nobel Laureate Robert Schiller's concept of irrational exuberance (and a book) title to the current speculative bubble of 2019. Over investments in startups and a lack of profitability in them are finally starting to catch up with the venture capital industry and the tech sector that relies on it. Investments by US venture capitalists have risen about six times since 2001 causing the total invested in 2018 to exceed by 40% the peak of 2000, the last big year of the dotcom bubble. But the number of IPOs has never returned to the peak years of 1993 to 2000; only about 250 were carried out between 2015 and 2017 vs. about 1,200 between 1995 and 1997.
The reason is simple: startups are taking longer to go public because they are not profitable. Consider the data. The median time to IPO has risen from 2.8 years in 1998 to 7.7 years in 2016 and the ones going public are less profitable than they were in the past. Although only 22% of startups going public in 1980 were unprofitable, 82% were unprofitable in 2018. The same high percentages of unprofitability have only been achieved twice before, in 1998 and 1999 right before the dotcom bubble burst. Furthermore, startups that have recently done high profile IPOs such as Snap, Dropbox, Blue Apron, Fitbit, Trivago, Box, and Cloudera are still not profitable.
Ride Sharing, Congestion, and the Need for Real SharingJeffrey Funk
Current ride sharing services are not financially sustainable. Although they provide more convenience than do taxi services, they are experiencing massive losses because they have the same cost structure as do taxis and thus must compete through subsidies and lower wages. After all, they use the same vehicles, roads, and drivers, and only GPS algorithms and phones are new.
They also increase congestion. Just as more private vehicles or taxis on the road will increase congestion, more ride sharing vehicles also increase congestion.
These slides describe new ways to use the technologies of ride sharing to reduce congestion along with costs while at the same time keeping travel time low. This can be done through changing public transportation systems or allowing private companies to offer competing services. For instance, current bus services, whether they are private or public, need to use the algorithms, GPS, phones and other technologies of ride sharing to revise routes, schedules and the premises that currently underpin public transportation. There is no reason a bus should be certain size, stop every 200 meters, or follow the same route all day. Algorithms and phones enable new types of routes in which designers simultaneously minimize time travel and maximize number of passengers transported per vehicle.hour.
Using the percent of top managers in IPOs (initial public offering) as a proxy for an industry’s/technology’s scientific intensity, this paper shows that the percentage of IPOs and of venture capital financing for science-based technologies has been declining for decades. Second, the percentage of PhDs among the top managers in science intensive industries is also declining, suggesting that their scientific intensities are falling. Third, the age of these top managers rose during the same period suggesting that the importance of experiential knowledge has increased even as the importance of PhDs and thus educational knowledge has decreased. Fourth, the numbers of IPOs and of venture capital funding are not increasing for newer science-based industries such as superconductors, solar cells, nanotechnology, and GMOs. Fifth, there are extreme diseconomies of scale in the universities that produce the PhD-holding top managers, suggesting that universities are far less effective at doing research than are companies. These results provide a new understanding of science and technology, and they offer new prescriptions for reversing slowing productivity growth.
This paper addresses the types of knowledge that are needed in entrepreneurial firms using a unique data base of executives and directors for all IPOs filed between 1990 and 2010. Using highest educational degrees as a proxy for educational knowledge, it shows that 85% of those with PhDs are concentrated in the life sciences and ICT (information and communication technology) industries and second, that those in the ICT industries are concentrated at lower layers in a “digital stack” of industries, ranging from semiconductors and other electronics at the bottom layer to computing and Internet infrastructure at the middle layer and Internet content, commerce, and services in the top layer. Third, industries with fewer PhDs have more bachelor’s and MBA degrees suggesting that PhDs are being replaced by them and not M.S. degrees. Fourth, age is higher for industries with the most PhDs thus suggesting a greater need for experiential knowledge in industries with greater needs for educational knowledge. Fifth, the number of Nobel Prizes tracks industries with high fractions of PhDs.
beyond patents:scholars of innovation use patenting as an indicator of innova...Jeffrey Funk
This paper discusses the problems with using patents as a measure of innovation and papers as a measure of science. It also uses data to show the problems. for example, the number of patent applications and awards have grown by six times since 1984 while productivity growth has slowed.
These slides discuss how to put context back into learning. Farm and other work at home once provided a context for learning, but this context has become much weaker as work at home as mostly disappeared Students once learned mostly from parents because they worked on farms, fixed things at home, and prepared meals. These activities provided a "context" for school learning, a context that has been mostly lost. These slides discuss how this context can be put back into learning and the implications for the types of people best suited for teaching and the way to train them.
Technology Change, Creative Destruction, and Economic FeasibiltyJeffrey Funk
After showing that the costs of most electronic products are from electronic components, these slides show how the iPhone and iPad became economically feasible through improvements in microprocessors, flash memory, and displays.
These slides show that the demand for most professions is growing steadily in spite of continued improvements in productivity enhancing tools for them. They also show that AI will have a largely incremental effect on the professions, in combination with Moore's Law, cloud computing, and Big Data. They do this accounting, legal, architects, journalists, and engineers.
Solow's Computer Paradox and the Impact of AIJeffrey Funk
These slides show why IT has not delivered large improvements in productivity and why new forms of IT like AI will also not deliver large improvements, except in selected sectors. The main reason is that the improvements in AI are over-hyped and because most sectors do not have large inefficiencies in the organization of people, machinery, and materials.
What does innovation today tell us about tomorrow?Jeffrey Funk
This paper was published in Issues in Science and Technology. It distinguished between the Silicon Valley and science-based process of technology change. It shows that more new products and services are emerging from the latter than the former.
Creative destrution, Economic Feasibility, and Creative Destruction: The Case...Jeffrey Funk
This paper shows how new forms of electronic products and services such as smart phones, tablet computers and ride sharing become economically feasible and thus candidates for commercialization and creative destruction as improvements in standard electronic components such as microprocessors, memory, and displays occur. Unlike the predominant viewpoint in which commercialization is reached as advances in science facilitate design changes that enable improvements in performance and cost, most new forms of electronic products and services are not invented in a scientific sense and the cost and performance of them are primarily driven by improvements in standard components. They become candidates for commercialization as the cost and performance of standard components reach the levels necessary for the final products and services to have the required levels of performance and cost. This suggests that when managers, policy makers, engineers, and entrepreneurs consider the choice and timing of commercializing new electronic products and services, they should understand the composition of new technologies, the impact of components on a technology's cost, performance and design, and the rates of improvement in the components.
Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

25. Building blocks for charging system
•Diodes and transistors are two of the key building blocks
•To increase circuit efficiency, designers are replacing silicon components with those made from SiC.Switching to the wide band gap alternatives slashes recovery times, which means that the devices cannot only turn on and off more efficiently–they can be deployed in circuits operating at far higher frequencies
26. Building blocks for charging system
•Going up in frequency allows a trimming of the sizeof the capacitors and inductors
•SiCdevices have a far higher maximum operating temperaturethan their silicon equivalents, so cooling demands are lower
27. Rates of improvements of MOSFETs
•New technologies in Power MOSFET will affect sales in the coming years.
