If polywell fusion is developed, in what ways will the world change for better or worse? Discuss.

You can do the same thing with polywells, and make the process continue even at night.
Even trees can't do that!
Atmospheric C02 is in trace quantities (although important for retaining heat). The beauty of fast growing plants is that they can concentrate carbon from the atmosphere cheaply and easily. If we have unlimited Hydrogen, and Carbon limited by biomass production, I wonder what percentage of the Hydrocarbon market can be filled. What would the "refinery gain" be if we had unlimited Hydrogen to combine with the Biomass carbon? I'd guess the volume gain would be huge relative to the biomass harvested.
I agree with everyone who says Biomass is a bad idea, but I think if it is used strictly as a carbon source, and not as an energy source, then it may work without deforestation and soil degredation that biomass alone would surely cause.

Global warming has been detected on Jupiter, Mars, and Pluto among other planets.
There is a 300 year solar cycle (not in the models) The current phase of global warming started in 1850. The stall since 1998 and the drop in the last year fits in with the solar model. We shall see if the drop is a fluctuation or a phenomenon. There also appears to be a 20 to 30 year cycle.
Still no sunspots:
There have been no regular spots. No large ones. Since the end of the last cycle.
If we go into an ice age we will be spreading carbon black on the ice to keep the place warm. Maybe even mirrors in space. And a lot of genetic engineering for crops.
Engineering is the art of making what you want from what you can get at a profit.
Thanks! That is so cool!!

How does helioseismology work?
The Sun is a hummimg ball of sound waves launched by turbulent convective motions in our star's outer layers. "The waves we monitor [using MDI] have a period of about 5 minutes," says Phil Scherrer of Stanford University, principal investigator for the MDI instrument.
By monitoring the Sun's vibrating surface, helioseismologists can probe the stellar interior in much the same way that geologists use seismic waves from earthquakes to probe the inside of our planet.
Intense magnetic fields around sunspots affect the transit times of sound waves bouncing from one side of the Sun to the other, variations that the MDI can detect and transform to reveal magnetic condensations (i.e, sunspots) on the hidden side of the Sun. Called "helioseismic holography," this technique can produce actual images of the far side of our star.
