Maybe in some areas of the world, Hydro can help supplement the baseload.

But not everywhere.

And in some developed countries, like the US, you're not going to see any more major, large-scale hydro projects due to environmental concerns.

And, as it is, Hydro only supplies a tiny fraction of the energy needs of the US (66% of all renewable energy in the US is Hydro, and the US currently utilizes renewable energy for about 11% of it's total consumption). So do the math.

Not to mention the environmental impacts.

Look at 3 Gorges in China.
The breakdown of vegetation in the reservoirs actually is releasing CO2 back into the atmosphere.

On top of this, the water in the area is highly polluted as the Yangtze river has BILLIONS OF GALLONS of sewage dumped into it every year, and the communities that were flooded out have released effluents and detritus into the waters.

The amount of silt being blocked by the dam upstream is gradually becoming a hazard to shipping, a flood hazard and will eventually effect the dams ability to control waterflow through the dam's own systems, reducing energy output.

The damn interferes with the ecosystem. Fish can't swim upstream to spawn, etc, etc.

Massive amounts of forest land was cleared and burned during the construction of the dam. Releasing tons and tons of CO2 into the atmosphere.

The changing ground pressure and altered water table have contributed to landslides and earthquakes in the region.

Clean, safe energy for the masses?

I think not...

Comment Problems with solid fuel reactors. (Score 1, Interesting) 142

Honestly. This is just going to continue being a problem for these overly complex, Rube Goldberg device solid fuel, pressurized water reactors.

Creating the fission reaction is the EASY part. Even keeping it under control is fairly brain-dead simple. The problem is that a psychotic amount of over-engineering goes into a complex, heavily layered disaster shutdown system. And, because the engineering is so complex, and the tolerances so exacting, even marginal variances explode the project from expensive to "snorting cash like a 50,000hp vacuum" boondoggle in negative three seconds.

This is one of the big reasons I'm a huge fan of molten salt reactors. In an emergency, you dump the reactor vessel, separating the fuel from the catalyst.
The reaction stops. And the system cools off. PLUS, there's no water under high temperature and pressure looking to explode and turn your powerplant into the Oz Scarecrow (they tore my legs off and they threw them over there, and then they tore my chest out and threw it over THERE!).

You all need to step back and take a breath.

It has nothing to do with scoring. Just the game itself puts me to sleep.
I don't watch football for much the same reason.
And, while I've enjoyed a few live baseball games, I don't go out of my way to go to them and never watch them on TV.
About the closest I come is Hockey. And, even there, I don't usually pay lots of attention.

All in all, I view the enterprise as a giant waste of time and money.

No, I'm just real big on rigorous peer review before allowing some guy to shoot shark piss up into my sinuses and dance around me holding a bunch of crystals before they fake pulling a bloody sheep's intestine out of me and tell me I'm "cured", but I should buy some snake oil just in case.

And Chinese research has a bad habit of claiming a lot of non-reproducible experiments as scientific fact.

There is no "overkill".

There is only "kill" with varying levels of confidence.

Shoot a guy once, and there's always the possibility he's not dead.

Shoot him 300 times, and yeah, you're pretty certain of him.

Shoot him with a missile, and now you're sure he's not just merely dead, he's really most sincerely dead.

Just...fire it from outside it's blast radius...(See "Fireball in 10x10 room")

People keep saying "with sufficient investment we could be 100% renewable". Sure, and everyone would be living inside a wind turbine coated with PV solar cells.

Probably not going to happen.

And you're still going to have areas where this sort of thing doesn't work for a good portion of the year.

Which means building a national power grid that could handle that sort of asymmetric load.

Now sure, we PV/Solar Thermal over Southern California, Nevada, New Mexico, Arizona and South/Central Texas. Maybe that's enough capacity. Maybe. Plus a few trillion batteries that need to be replaced every 5-10 years.

I'm pretty sure the investment for advanced nuclear would be significantly less and yield greater energy output.

Do a little bit of math. Find a nice strong wind turbine. Now calculate how many of them you'd need to provide even 25% of the country's 4 BILLION megawatt hour annual demand.
Now do the same thing for PV Solar.
Now do the same thing for Solar Thermal.

Now calculate the land usage.

Come back when you have a realistic answer.
