Careful, we now account for 5 percent of annual CO2 emissions. That is not an insignificant number. Those percentages sound small until you consider that .0384 percent accounts for at least ten degrees of radiative warming on this planet. Also, we account for nearly 100 percent of that increase...
When we almost doubled the amount of it in the atmosphere. I know that is a bit terse. It isn't a poison, we just need to find a way to reach a new equilibrium and understand what it means to our long term climate situation. On the up side, we probably interrupted the glaciation cycle!
There is...
They will be considered, where they are a natural choice and extremely cheap. However, as part of a national energy policy they are a complete disaster. I live in a major ethanol state. Even the people who are(were) profiting from it know that it is nothing more than another farm subsidy.

I classify bio-fuels as an impossibility because it needs to be reasonably scalable and the amount of available energy needs to be vastly greater to our requirements, even if only in a geographically limited area such as geothermal.
Biofuels are all indirect solar. Compared to photovoltaic...
That is what I expected. Apparently, there is no difference in engine performance. I would not be surprised if you didn't see a major effort, in the coming years, to switch US commercial air transport to these fuels. Decoupling their largest expense from the world oil market could be the only...
It is more a recognition that there isn't a path to a practical alternative to turbofans and Hydrocarbon fuels. The engines keep getting more and more efficient, and jet fuel is one of the safest way to carry extremely dense energy with you.
If we hope to maintain our travel habits, we will...

*People who suggest either of these have no concept of the scale of our energy consumption. Mathematically, it is impossible for these ever to be a...
You could use steel wool. I see demonstrations where it will ignite at the voltages you are talking about. The best options are Tungsten and Magnesium. Tungsten can be a little had to come by in the quantities that you are interested in. Magnesium is sold in block form at most camping stores...
Mills is a douche bag of the highest order. I love this little piece FTA:
Mills' theory, which he expounds upon in his self-published 2,000 page book, The Grand Unified Theory of Classical Quantum Mechanics, rests on what he describes as his discovery of the hydrino - an altered version of...

I would be very careful about calling Fusion a "pipe dream". The over optimism of the first generation of researchers has certainly caused a high amount of skepticism with regard to any technology road maps.
There is a clear path to working plants. There has also been a...
I think you have largely hit the nail on the head. Nuclear, whether fusion or fission, is our only long term base load power resource. With nuclear reprocessing our fission resources could last for thousands of years.
Your fusion articles are primarily focused on laser inertial confinement...

Fair enough. I have been lurking on this site for awhile. There is a tremendous amount of insightful information from nearly everyone who posts. You are right that I should be contributing in other threads.
I guess I wasn't overly compelled as I was primarily trying to read...

Fine, but my point was that the "learned" genuine journals are not to be trusted either, nor reports from ostensibly qualified and authoritarian sources.
In other words you can't expect us to simply roll over and accept every utterance of a scientist without question. Those...

I think you may have misunderstood my comments. I mentioned the HIV denial example to illustrate the attempt to appear scientific when clearly you have a political agenda. Those articles can be found in "Journal of American Physicians and Surgeons". Sounds official...

Very true.
Here is some additional reading on the subject of peer-review.
I read your first two articles. I must say that I don't think you understand what the term "maverick" means. Try to defend science in the face of todays pseudoscience and you will very quickly...

I took a day off to think about your comments. I don't think that you are being entirely unreasonable. So I will try to explain to POV my reaction comes from.
I am a full time working EE that is also a PhD student. I am not part of any active climate research. My background...

Why would you argue a 100 plus year trend when you've got almost 5000 years at your disposal? Looking back over that time frame, you'll see that temperature is cyclical, and there was been at least two times over that interval, pre-industrial times in fact, when...

The graphs of temperature from b2theory have a vertical axis scale of approximately +/- 0.5 degree C. This much accuracy is shown with curve fit line when the vertical gradient in still air can be 1 degree per foot and the water temperature variation with depth is...
