"The intermittency... can be addressed by... natural gas" That is indeed a great way to argue that renewables can do it all. Cynical individuals would even conclude that they just use renewables as a convenient talking point to s

You're forgetting the tank. There are a few hydrogen powered cars on the road, their tank weights about 125kg and stores a whopping 5kg of hydrogen.

How is a reactor at partial power less efficient? I suspect you're not talking about thermodynamic efficiency, and it's not energy that (you think) would be wasted.

Nuclear ramps just fine. French nuclear plants reportedly ramp routinely between about 50-100% capacity, so this isn't just theoretical. Going from full power to less than about 40% tends to run you into a Xenon pit, which causes a t

In actual experience, the people in question weren't "out to get me". They complained about things going wrong (due to their own actions), and I listened. Now their failures are my fault, according to some bizarre logic I c

Does anyone have insight into the chemistry of these nanoparticles? Because, clearly, cars don't emit gold. Cars do emit platinum and palladium from degrading catalysts, but these don't condense from a gas phase, as the article i

The log10 method is incorrect: math.log10(999999999999999)==15.0. (That's 15 nines.) Good job teaching unreliable algorithms.

The source calculates somewhat optimistically. They assume storage at 80bar, while mentioning that actual storage is at 200bar. They also assume 60% efficient conversion from methane to electricity, while using 55% in other parts of the p

Well, my first question would be "How does it work?", then I'd have a good laugh after you explained it. But that's just me... Anyway, nuclear fans know about the trade off between safety and cost. It is the antinuke z

Both Moltex Energy and Elysium Industries are developing fast waste burners, and both are privately funded. Neither operates in the USA, though, because that's where the government gets in the way. The US government defunded the IFR

You're a victim of a common misconception. Nuclear reactors can ramp up and down as quickly as the control rods move. Check out the Borax experiments (from shutdown to full power in seconds) and the TRIGA reactor (from shutdown to gi
