Guest lecture given to first-year engineering students at the University of British Columbia, 2013 Sept 10. (APSC 150)
Title: A sustainable (energy) future
After a brief preface on intellectual self-defense, the presentation discussed the science underpinning our understanding of climate change, followed by an analysis of worldwide energy use.
The experience curve was introduced as a force arguably more powerful than Moore's Law (because it applies in virtually every manufacturing sector) and the main reason that renewables (wind and solar, for the time being) are likely to displace fossil fuel and nuclear power in the coming decades -- not for reasons of conscience, but reasons of cost.
Lastly, the metaphor of the "utility death spiral" was introduced to explain the probable impact of efficiency and renewables, on the fossil-and-nuclear dominated utility sector, in coming decades.

U.S. Defense Threat Reduction Agency (DTRA) favorably evaluated Widom-Larsen theory of LENRs in official contract report originally published back in March 2010. Unclassified document very recently became publicly available on the U.S. Dept. of Homeland Security’s digital library website. Quoting from DTRA report’s conclusions: “Could the W-L theory be the breakthrough needed to position LENR as a major source of carbon-free, environmentally clean source of source of low-cost nuclear energy??”
The main thrust of this brief presentation, prepared for a module that counted towards my MSc. Architecture: Advanced Environmental & Energy Studies, was to question the wisdom of defending the coastline using large scale engineering defences, and to work with the changing coastline, questioning - should be laying the foundations for offshore wind farms, on shore in areas that we know are prone to flooding, when they are easily accessible. Discuss.
Tidal power or tidal energy is the form of hydro power that converts the energy obtained from tides into useful forms of power, mainly electricity.
Although not yet widely used, tidal energy has the potential for future electricity generation.
Tides are more predictable than the wind and the sun.

Enormous potential future value for diversified portfolios of renewable, fossil-fueled, and nuclear power generation --- enable grids to have resilience against extreme weather events related to climate change and “Black Swan” volcanic eruptions.
Proverb: “In the first place … an ounce of prevention is worth a pound of cure.” Benjamin Franklin (1735). Fukushima lessons: mitigate improbable extreme events if not too expensive; $200 million was thought too costly to fix backup generators in 2006 but the ‘cure’ for the 2011 nuclear disaster now costs $189 billion and could take 30 - 40 years.
What may appear ‘greener’ and less $$$ in myopic short-term decision-making about grids could end-up being extremely $$$ expensive or catastrophic in longer-term. Data suggests that is it too risky for society to put all its energy “eggs” into a single renewable basket. Lattice therefore believes balanced diversity of different types of grid power sources is best strategy for insuring 99+% future reliability and excellent resiliency of electricity grids facing onslaughts of extreme weather events and low but non-zero probability for catastrophic Black Swan volcanic eruptions.
Since high % of renewable energy sources on electricity grids is a new phenomenon and unexplored territory, there aren’t preexisting road maps to guide government regulation and critical implementation by industry. Private sector companies by nature are concerned with short-term bottom line profitability and have more narrowly focused interests; by contrast, government is responsible for insuring national energy security over much longer time-frames and broader range of grid-threatening events.
Rick Perry/DOE’s controversial NOPR to FERC in September created an important opportunity for U.S. government and industry to begin productive dialogue about how to enhance the U.S. electricity grid’s ability to maintain present reliability and adapt to climate change.

Greener Power for More Electric VehiclesPaul H. Carr
GREENER POWER FOR THE INCREASING NUMBER OF ELECTRIC VEHICLES (EV)
by Paul H. Carr
Charge EVs at Night
- Electricity demand from 12 PM to 6 AM is very low.
Install PV charging stations for daytime charging.
More electricity by using the waste heat of present generators.
-Coal, nuclear 32% efficient
- Natural gas turbines 44% efficient
Replace carbon emitting coal and gas with nuclear.
Fuel Cells are becoming the preferred alternate energy but unless the constraints are understood and dealt with it will not be adopted at the rate it should

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Toxic effects of heavy metals : Lead and Arsenicsanjana502982
Heavy metals are naturally occuring metallic chemical elements that have relatively high density, and are toxic at even low concentrations. All toxic metals are termed as heavy metals irrespective of their atomic mass and density, eg. arsenic, lead, mercury, cadmium, thallium, chromium, etc.

4. Water-Powered Car Might Be Available by 2009
“Forget cars fuelled by alcohol and vegetable oil. Before long, you might be able to run your car with nothing more than water in its fuel tank. It would be the ultimate zero-emissions vehicle.
While water is not at first sight an obvious power source, it has a key virtue: it is an abundant source of hydrogen, the element widely touted as the green fuel of the future.”

5. Nuclear versus Wind
“If we’re going to cut greenhouse gases by 60%, there’s no other possible way of doing that except through renewables”
“Anybody who is relying on renewables to fill the energy gap is living in an utter dream world and is, in my view, an enemy of the people
“We have a huge amount of wave and wind”
“Nuclear is a money pit”
