The Blueprint for Serving a Million School Lunches — Every Day | Wawira Njiru | TED
Sometimes feeding just one child can seem challenging. Not for entrepreneur Wawira Njiru, who’s gone from serving lunch to 25 children from a makeshift kitchen to establishing her nonprofit, Food4Education, as a cornerstone of Kenya’s school meals system. Currently serving half a million meals to children every day, she’s now thinking even bigger. Hear about…

Bob Wallace

@Greg Warner I don’t understand how war fits in the discussion but I do agree. Switching from fossil fuels to nuclear would cost less than a major war.
But let’s look at what we are facing. The cost of climate change is growing and will become extremely expensive if we don’t limit the potential damage. Think about the cost of building seawalls to protect our coastal cities, the loss of the lower part of Florida, and replacing all our port facilities including all navy facilities. It would be cheaper to move to nuclear energy than to suffer all that loss and cost. And that’s just the rising sea level problems.
But we have two routes to avoiding extreme climate change when it comes to removing fossil fuels from our grids. We can turn to nuclear energy or renewable energy. Which we choose is going to be based on cost. People will highly resist any abandonment of fossil fuels if it causes their utility bills to increase.
Replacing fossil fuels with nuclear energy would make electricity more expensive.
Replacing fossil fuels with renewable energy would make electricity cheaper.

@Bob Wallace Current renewables only seem less expensive than thorium based nuclear power because the renewables are heavily subsidized for mostly emotional reasons. They let the upper middle class feel less guilty about operating their excessive McMansions.
Ideally the Thorium reactors would produce base load electricity while solar and wind would store the energy to be used at high demand times. You can consider LFTR (Liquid Fuel Thorium Reactors) to be both green, no high level nuclear waste, and creates more fissionable fuel than it creates. This fuel cannot be used in nuclear weapons.
The greatest opposition to this technology are the owners of the current fossile fuel plants and the petroleum infrastructure that supports them. They are not about to put their money at risk until they have another place to invest. Thorium fueled energy is that place.
Bob Wallace
December 9, 2020 at 5:34 pm
@Greg Warner Let’s start with the cost of nuclear fuel. The cost of currently being built reactors (Hinkley Point and Vogtle) will mean electricity costing about $0.15/kWh. Of that the cost of uranium fuel will be less than $0.01/kWh. Even if thorium was free it would not make electricity from those four reactors affordable.
Now, subsidies. New nuclear in the US will receive the same subsidies as wind and solar.
Subsidies serve two purposes. Either to assist a new technology/service to grow large enough to stand on its own or to increase consumption of a product/service that is considered to be for the common good. Nuclear energy was highly subsidized during its initial phase.
Between 1947 and 1999 nuclear received average annual subsidies of $3.50 billion. (53 x $3.50 billion = $185.6 billion).
Between 1994 and 2009 wind and solar received average annual subsidies of $0.37 billion. (15 x $0.37 = $5.6 billion)
$185.6 billion / $5.6 billion = 33x. We spent vastly more to help nuclear get out of the starting blocks than we’ve spent for wind and solar.
We’re on track to phasing out wind and solar subsidies. We have recently started subsidizing existing paid off nuclear plants. For the common good of avoiding extreme climate change it is probably wise to subsidize low carbon electricity in order to make fossil fuel produced electricity less competitive and coal/gas plants to shut down sooner. IMO, we need a price on carbon. The market will then pick the most affordable low carbon technologies.
Non-subsidized wind and solar are now massively less expensive than non-subsidized nuclear.
I used to support nuclear energy as our best way to quit fossil fuels and avoid extreme climate change. But that was when solar and wind were massively more expensive than they now are. Back then solar panels cost over $10/watt but now they are $0.17/watt, a 58x drop in price. Wind was around $0.30/kWh but is now approaching $0.02/kWh, a 15x decrease.

Do we have a carbon credit type structure between nations? High carbon footprint countries should pay low carbon footprint countries on a per capita scale. This might drive high footprint countries to prioritize carbon reduction. For underdeveloped and low footprint countries they would receive funds to prepare for climate changes, while also incentivizing them to keep their footprint low as they develop (ie not repeating the mistakes of other developed nations).

Pretty good stuff, but it seems to assume everything we currently do needs to stay the same. Rampant consumerism live on! I think we should be moving towards the Wellbeing Economy, where the priority is the wellbeing of people and the planet – before profit. No, that does not mean you can’t make a profit. It is just a change of priorities, and timescale.

Looks like Tesla has solved the battery problem. They’re cutting the cost by more than 50% and their lithium iron phosphate tabless batteries use no cobalt, only highly available materials.

I have been following this stuff for decades…I can’t imagine ‘Green Hydrogen’ being a real thing, except to rescue Natural Gas miners…it’s where they actually get their hydrogen from; use the sebatier process instead to make denser carbon fuels if you have to. The felating of Capitalism is also a non-starter; capitalism is to an economy as Diabetes is to healthy gut…commerce out of whack.

For everyone advocating for nuclear. Unfortunately, nuclear is quite expensive, a lot of money and expertise is required to build, maintain and decommission a nuclear power plant. There are a lot of safety and location requirements, plus it’s a big chunk of generation in one place (up to 3000MW an equivalent of 1000-2000 wind turbines), so a powerful distribution grid is needed.

Who cares about insulation in California. It’s warm there. Not a peep about how solar panels disproportionately heat the air causing global warming. Not a peep about nitrogen dioxides, which the experts claim is far worse than carbon. Not a peep about climates in most parts of the world that don’t have enough solar energy or wind just to heat hot water, let alone all other needs.
If they sanitized their hands, wouldn’t it be OK to shake hands?

100% reliability on electricity is a risky strategy. Even if you were able to generate enough power for the whole world using solar and wind, the electrical grid is still vulnerable to EMPs! If you get rid of everything else that is causing the rise in Co2, you are choosing a source of energy that is vulnerable to hacking and EMPs. Thats dangerous!!!
