I agree the particle accelerator is pretty cool, of course transporting power around the globe is not as easy as stringing a wire, for every mile of wire you lose power due to the resistance of the wire. This is the problem of 'power transmission'. This is the same reason you can't build nuclear power plants in the middle of a desert 500 miles from anywhere and ship the power out sadly. That being said, at .40/watt y…

We can build power plants in the middle of the desert and ship power out. The technology exists; we just haven't done it yet. Transmission losses are not a concern for superconducting cables (though maintaining the cryostat jacket is). Such cables are currently being proven before being used in larger grid connections. http://spectrum.ieee.org/energy/the-smarter-grid/superconduc... http://www.htstriax.com/columbus.ht…

Actually, we have, albeit with varying degrees of success: http://en.wikipedia.org/wiki/Solar_power_plants_in_the_Mojav... http://articles.latimes.com/print/2012/mar/04/local/la-me-so...

IMO, as long as the tax is inline with the actual external costs it of other forms of energy generation it's not a bad thing. ( http://en.wikipedia.org/wiki/Externality ) It's basically renaming a sin tax as a green subsidy but there is value in having that tax even if it's revenue is mostly wasted.

I agree in principle with the idea that carbon-based energy has a ton of negative externalities (megatons, in fact...), so there should exist a relative subsidy between it and green. The issue is that creates even distortion between the energy sector as a whole and the rest of the economy, since fossil fuels are already subsidized (through not pricing in the negative externality) and we're adding a separate subsidy t…

I think they are taxing existing energy sources to pay for the subsidy so on net people using electricity pay the actual cost for green power and other sources based on the actual mix of energy sources used in production. It only the producers who notice the cost difference this tax / subsidy creates.

That is some amazing technology right there, almost fun to read because it sounds like science fiction but it's real. And privately designed/built/owned particle accelerators? It's definitely a new era. What if one day the other side of the globe getting sunlight powered the grid for the other half? Of course this would require very peaceful nations on each continent, so even if we had the cost-effective technology n…

I don't think privately designed/built/owned particle accelerators are that uncommon actually; hospitals have been using cyclotrons for cancer therapy treatments for at least a few years (http://en.wikipedia.org/wiki/Cyclotron#Usage), and I'm fairly certain these are built and sold by medical equipment manufactures like Advanced Cyclotron.

No denying it's still amazing though...

And using electric cars for battery storage too for excess power generation. Just imagine the world if it was 10 cents per watt instead of $1 a watt for solar. I hope I live long enough to see it. Dare we dream 1 cent per watt, just like what has happened with CPU development in the past three decades? Could we have 1 cent per watt solar in 30 years? 50 years? 100?

If current trends[1] continue, it will take about 15-25 years for solar energy to become cheaper than fossil fuels, which seems like a reasonable length of time for a trend to continue. To get the installation cost down from an estimated $1.40 in 2020 to $0.10 and $0.01 with the same trend would take 30-50 and 60-100 years, respectively. 70-110 years is definitely further in the future than I am comfortable peering;…

The price of fossil fuels could also go up. We are starting to shift production from conventional drilling to more expensive methods like tar sands.

Transportation of electricity around the globe is not neccessary. Electricity usage is considerably lower during nighttime. Thus solar and wind fit in with our natural rhythm quite nicely. And it is also produced near the place there it is being consumed. Another plus. But still the author is right, we need ways to store electricity and we will also need a much more flexible grid than the one we have today. The neo l…

> Thus solar and wind fit in with our natural rhythm quite nicely. It's not that nice, because power output from wind/solar plants is random (depends on things like cloud cover or wind strength) and it causes problems in power grid, where power demand must meet the supply exactly, or bad things will happen. "Without Hot Air"[1] covers this, and other renewable-related issues quite nicely and with real data. I recomme…

When solar and wind power input is not meeting demand that seems like a good time to spin up the spare fossil fuel generators, at least as a transitional sort of thing. Maybe in the near future excess wind / solar power can be stored as chemical fuel, and burned during peak usage.

An 80% / 90 % cut in fossil fuel usage or higher would be a huge thing though!

Most of the power loss is related to using AC instead of DC.

Perhaps you haven't seen the Nelson River project.

This is why I welcomed the backlash and even some of the sensationalism regarding the nuclear explosion in Japan. Even if I realize that nuclear energy could be safe and it's good to have an alternative that is cheap enough to compete with coal, I'd still wish we'd spend all those billions switching from nuclear and putting most of them into renewable energy technologies, which should be the future. The arguments aga…

The idea that solar, wind and geothermal energy can replace nuclear power for electricity generation in my lifetime (the next 35 years) ignores the reality of how much electricity we consume and how it is currently generated. Here's a link to a graph created by the Lawrence Livermore Lab that quickly illustrates the miniscule impact of doubling, tripling, or even quadrupling the three primary alternative energy sourc…

There is some other good stuff at that site.
