$3 / MWH by 2060?

Eleventy !!1!?!1

$3 is practically zero compared to the last 200 years.

$3 is practically zero compared to any form of power ever used by humans ever.

At $3 per MWh, so many technologies suddenly become feasible.

It'd be so cheap to incinerate toxic waste in plasma furnaces that waste dumps would be remediated just to save on maintenance costs.

Aluminum would replace steel in nearly every application.

Titanium would take over for today's current applications of aluminum.

It'd be worthwhile dumping incinerator ash into electroplating baths to recover all the heavy metals.

We'd be making nitrogen fertilizer and cement using electric arc furnaces instead of fossil fuels.

Desalination would be so cheap that any potentially arable land near coastline would be irrigated.

Restaurants would air-condition their outdoor patios.

The Irving Family (billionaires in New Brunswick, with their own oil company) installed a heated driveway that would melt snow, so they wouldn't have to shovel it. Even they couldn't afford to keep it running.

With cheap electricity, it might be feasible to install heating elements in roadways, as being cheaper than paying for snow ploughs.

I think you are absolutely right about it being practically zero.

I generally carry in my head the ballpark figure that energy costs about $100 / mwh.

$3 / mwh is a 97% discount, that's as close to zero as makes no odds.

Desalination and pumping of water would be so cheap that you could use any potentially arable land within a 100 km of the coast, or more. And pump water in the Aral and Caspian Seas or back up the Himalayas or Greenland uplands to form re-glaciers.

We could mine the oceans for lithium and gold and everything else that is in there in small concentrations and do so more cheaply than we could mine it out of the ground.

I actually wonder if it would be cheaper for every city by the coast to run desalination plants rather than get drinking water from local rivers.

When the cost of energy is less than the cost of running pipes to reservoirs, it'd be cheaper to purify and reuse your sewage.

The output from my local sewage treatment plant is already cleaner than the lake it is dumped into (which is also the water supply for the metropolitan area). With cheap electricity, you could add UV arrays and reverse osmosis filters, to remove the "ick factor" currently preventing most cities from recycling their sewage.

I see that - especially given as you say the sewage needs to be treated before it goes back in the water anyway.

The city of Windhoek has been recycling their sewage for 53 years out of necessity. Cheap energy would make this economically viable for other cities. That includes those near coasts - since you have to manage your sewage sludge anyway, using sewage as your water source saves you from having to also manage disposal or dispersal of concentrated brine from seawater desalination.

Sandy looked at me in puzzlement when I squeaked loudly when I read that!

The NHS didn't actually have to reinvent the wheel on track and trace, either...

What is going on here? Are they actually making a Robin Williams bio-pic? What exactly is this clip?

Thanks for the explanation. This is not something people who wanted to make a movie did back in the days when I knew anything whatever about the movie industry.

Obviously his RW impression is indeed amazing. How well he can act would have to be seen.
