Green energy is dumb

[Klause]

Look up ITER and DEMO.


THERE YA GO CHUCKY I fixed your energy problem for ya!!

Wow. Not a single response.

Where's all the green energy loving people?


Fusion reaction... commercial scale Tokomak reactors.


Iter will use 50MW to power up and produce 500MW.

Inside a magnetic containment vessel.... All the benefits of a compact nuclear power plant without any of the dangers, radioactivity, or waste...


Why spend billions of taxpayer money on wind and solar when this is around the corner?

[Klause]

Also noteworthy, the USA is involved, yet Canada is absent...

Does after 2050 mean just around the corner?

So back to the windmills apparently

[Klause]

FYI... The only Canadian TOKOMAK... is here in Saskatchewan:

Let's throw 20 billion more at Fusion. and quit building windmills... It's almost 2020... 40 years till we have limitless power...

Or we can cause the next 3 generations to be in debt for no reason... and use up a bunch of rare earth resources for nothing.

We're shutting down power plants before their EoL and replacing them with un-stable, and non-sustainable "green" energy that's going to bankrupt us... Hmmmm....

Nothing but crickets. The truth comes out klause the lefties only want to tax us they know man made climate change is a hoax.

This green BS, the Paris Accord, carbon tax and all the wasted resources building windmills and solar panels will be derilect and ditched in 10 years.

Number one- no one has proven that our best friend Carbon, the backbone of all organic things and food creating processes, is the nemisis of the world, and no one can give any assurance at all the the Western World can do one iota to slow down an obscure and non-specific "problem" (or maybe not a problem at all.)

All that will happen with this green blunder state, is that western wealth and our taxes will be wasted. Klause, good on you for posting this alternative but really, do we need an alternative for something that is not a problem at all. On the other hand, 33 years is a very short time, basically 1 farming career. In that time there will be lots of innovations and I suppose that can't be all bad.

Farming career only sposed to be 33 years ?? Wtf ? Lol

Sitting in great falls at the truck stop running some basic math. Trying to figure out what it would take to make an all electric truck fleet possible.

If we say the average truck north of 49 in the prairies is running about 900km/day @ 5mpg average we get 508.15L of fuel consumption per day. Wiki tells me diesel fuel contains 38.6MJ/L and a large diesel engine is somewhere around 45% efficient. That means 8826.56MJ is actually needed to punch a truck down the road for the day if it was 100% efficient. If we assume we could power the truck with an electric motor that is ~95% efficient we would then need 9291.12MJ per day to punch the electric truck down the road.

Now if we convert that to kilowatt hours, 1KwH=3.6MJ, so we'd need a 2580.88KwH battery. Just like you don't run your diesel tanks to empty at the end of the day and try to keep a reasonable cushion of a couple hundred liters, let's say we rig this truck with a 3000KwH battery. On the HIGH side, wiki says Li-ion packs .265KwH/kg. So the battery pack would weigh 11,321kg in lithium ion alone for a 3000KwH battery.

Now here's where things start to get Ugly... if we knock the fuel off the truck that gains us 500kg in payload, but the battery Costs us 11,321kg, so nets out at 10,821kg. I won't even discuss the added weight from additional axles and tires just to support this extra weight. Regardless, we've lost 10.821mT of payload, or nearly 25% for a Canadian super b.

At the end of the day we have to charge these things up over 8Hrs which is the mandatory daily reset. So if we assume absolutely 100% efficiency in charge and discharge then we just have to replenish the 2580KW over 8 hours, which would require 322.5KW every hour for 8 hours, or basically a 322.5KVA generator running with its tounge hanging out for 8 straight hours. Put another way, at 240Volts, you will need a 1344amp service to plug that truck into.

I'm sitting in a truck stop with probably 100 trucks sitting here, that means a 134,000 amp service so that all these trucks could plug in... at night... when there's seldom much wind blowing... blow this out for all the class 8 trucks that are on the road not only in Canada, but north America.

Maybe my assumptions and calculations are way out to lunch, but I just don't see how this is possible on renewables! Or how we are going to be able to source the shear quantity of precious metals needed... not just for the batteries, but the windmills and solar cells.
