I don't see any problems with carbon dioxide removal, aside from potential local environmental problems. The methods include reforestation, adding iron to the ocean and grinding up serpentine.

Solar radiation management, like adding sulfates to the air, has lots of global environmental effects, and it doesn't do anything about acidification of the oceans.

It's best to consider these separately.

Tapes has a crapload of drawbacks, write speed, read speed, the fact it's sequential (random access is painful) but it remains popular because you can drop it, smash it, submerge and then freeze it and all you have to do is roll the tape into a new case.

Maybe they have fixed it, but I heard some old stories about dropping tapes corrupting them.

Nicely written post, but you don't know what you're talking about.

Hydrogen is not the strongest reducing agent amount the stable elements. If you go by electronegativity it is cesium. Cesium is rather heavy, though.

Lithium would make a very good cathode (if we could just control the dendrites), but it's not what lithium-ion batteries use. Transition metal compounds are far from ideal for cathodes, but they have the advantage that we can make them work pretty well.

Lithium-sulfur is potentially the next battery after lithium-ion, if only we can make them last long enough.

I think you ask too little. What get me are quotes like this;

The team is looking at a price point of $25,000 for an EV battery range of 300 miles, which would be competitive with a 40 mpg gasmobile.

That's not actually what the team said, it is a paraphrase of something Chu said about what is desirable in an EV. The author apologizes in the first comment.

Don't blame the researchers for the idiocy of the article's author.

+ - Lawsuit Filed To Prove Happy Birthday Is In The Public Domain; Demands Warner Pa-> 2

Submitted by Anonymous Coward
An anonymous reader writes "Happy Birthday remains the most profitable song ever. Every year, it is the song that earns the highest royalty rates, sent to Warner/Chappell Music (which makes millions per year from "licensing" the song). However, as we've been pointing out for years, the song is almost certainly in the public domain. Robert Brauneis did some fantastic work a few years ago laying out why the song's copyright clearly expired many years ago, even as Warner/Chappell pretends otherwise. You can read all the background, but there are a large number of problems with the copyright, including that the sisters who "wrote" the song, appear to have written neither the music, nor the lyrics. At best, they may have written a similar song called "Good Morning to All" in 1893, with the same basic melody, but there's evidence to suggest the melody itself predated the sisters. But, more importantly, the owner of the copyright (already questionable) failed to properly renew it in 1962, which would further establish that it's in the public domain"

150 charge/discharge cycles is not very much. That is only 5 months use.

Initial testing of batteries is usually done at C/20, or less than one cycle per day. I don't know if they sped this up any, but it would still take quite a while for 150 cycles. You're asking too much from a research project.

I used to show up at work before 6 and leave after 19. I only did this three days a week, though. It was totally at my discretion how I put in my 40 hours, but it was too long a drive to do it more often, and driving during rush hours was also not appealing.

But since I am long retired, I chose the last option.
