A Flexible Paper Li-ion Battery Yi Cui/Stanford UBatteries are the bane of all portable electronics. Bigger, heavier batteries make devices less portable, while smaller batteries lead to low performance or short battery life – or both. But while Stanford’s new lithium-ion batteries don’t necessarily cut down on footprint, they certainly cut down on mass; the new ultra-thin, rechargeable battery has been fabricated on a single sheet of paper, making it super-light, flexible, and as portable as a piece of A4.
The batteries were fabricated by materials scientists at Stanford by depositing a thin film of carbon nanotubes followed by another thin film of metal-containing lithium compound on top of the nanotube layer. These thin bilayer films are layered onto both sides of a piece of ordinary paper, which serves as both the structural support of the battery as well as the electrode separator. The lithium serves as electrodes, while the nanotube layers are current collectors.
The result is a working battery just 300 micrometers thick – that’s 300 millionths of a meter – that is flexible, super-thin, and more energy dense than other thin-bodied batteries. It’s also durable; over a 300-cycle recharge test, performance remained satisfactory. It’s also fairly easy to fabricate, making it far more commercially viable than other methods of downsizing battery technology.Related Articles

New Process Uses Genetically Modified Yeast to Turn Carbon Dioxide Emissions Into Bricks for Construction
CO2 To Bricks Carbon dioxide is bubbled into water and then added to a solution of mineral ions. Genetically engineered yeast help turn the dissolved CO2 into solid carbonates. Patrick Gillooly/MITA method developed at MIT and modeled after seashells could provide a new way to sequester carbon dioxide — by using it to manufacture new carbonate building materials.
To reduce the amount of carbon dioxide in the atmosphere (and therefore lessen global warming), some researchers are studying ways of sequestering it in underground reservoirs. But this is expensive and difficult, and has not yet been achieved on a large scale. MIT engineer Angela Belcher is leading an effort to remove CO2 from the atmosphere and construct buildings out of it.
To make the CO2 bricks, Belcher and her graduate students modified baker's yeast to express genes that are normally found in sea creatures like abalones, which make hard carbonate shells. Carbon dioxide is bubbled into water, and then combined with mineral ions to make solid carbonate materials. Enzymes in the yeast help the mineralization process.Related Articles

Other environmentally friendly bricks use fly ash, a byproduct of coal power plants, or even sand and urine. Bricks made of CO2 could solve two problems by sequestering CO2 and eliminating additional CO2 emissions from traditional brick-making.
Belcher and her graduate students are not the first to propose solidifying captured CO2, but they are the first to prove a biological process works. It involves no chemicals or temperature changes, unlike chemical solidification methods.
The researchers hope to scale up the process so it could be used in a power plant or industrial factory.

Sneak peak @ Chapter 2
Friday, July 23, 2010
hungry, so I put a potpie in my little counter top oven, then sat down
to watch some TV. I found a movie (Monkey Shines), which seemed to fit
my screwed up mood, then sat back in my old Good Samaritan chair and
relaxed until my food was done. I got up to get my pie when I heard a faint knock on my door. I took
the pie out of the oven and sat it down on the counter. I ran to the
door and to my surprise it was Jasmine. I looked at her face, dumb
stricken. She was wearing a hooded-sweatshirt, hood up and baggy
pants, all gray. It was as if she was hiding from the world. “Aren’t you going to at least invite me in,” she said in a faint
tear-filled voice? “Oh I’m sorry, come on in. Can I get you something to drink?” She walked in and I shut the door. She then said. “No, I’m ok.” Her
voice cracked. “I’ve been thinking about your call.” “Yeah, we really need to talk, sit down please.” “Jack, before I go any further, I need to know something.” I noticed she wouldn’t look me in the eye and I was confused. “Ok, go ahead.” “Were you at my mother’s tonight?” “Yes ma’am, I was.” “I thought so, why were you there?” I knew that I wouldn’t lie to her, but I didn’t think telling her the
whole truth with her being in what I knew was an upset mood, would be
the right thing to do right now. “Well Jazz, dad called me and said
that she had told him she needed to see me, it was important. So I
went over there.” She finally looked at me in the eyes, but it wasn’t the look I had
longed to see. She had been hurt and hurt deep. To my dismay it was my
own damn fault. She asked as she was sitting down, “Does this have
something to do with your not coming around for a year?” I sat down beside her. “I didn’t come around because my business
tanked and I couldn’t pay back the debt.” I paused then said, “there
is something else that honestly Jazz, it scared the hell out of me.” I saw her tears well up when she asked, “But why not come around me?
Jack, you and I have been so close for so long. I don’t give a damn
about that money, I care about you and I thought you cared about me.” Her voice radiated the hurt I had caused. She was now crying, I tried
to take her in my arms but she pushed me away. “Ok Jazz, if you promise to keep an open mind I will tell you. This
is hard as hell for me to say especially to you, so please bear with
me.” “Tell me, I’m listening!” Her tears continued to flow from her
beautiful blue eyes. She still wouldn’t look at me for any significant
length of time. “But Jazz, this is far different than anything we have ever talked about.” “Just tell me, Jack! Can’t you at least do that,” she cried? She had me on the verge of just telling her to never mind, but I knew
I was the cause of all this, and had to be a man and face up to
whatever punishment the woman I love, more than anything had in-store
for me. “Jazz, do you remember during last Christmas, one minute we
would be talking like our old selves, but then I would walk away and
try to do something, anything different?” “Yeah I remember, I thought this whole time I did something to you and
you were mad at me.” “Jazz, I could never be mad at you, but I’m about to tell you
something about last Christmas and long before, that could explain my
actions. Don’t get me wrong, I’ve screwed-up not talking to you about
it sooner. I just couldn’t find my words.” I could feel my heart
beating so hard it hurt. “I already know I did something, but for you to stay away for a year.
Jack, I thought I meant more to you. If nothing else you could have
called me? You couldn’t pick up the damn phone?” Her tears affected me
to the point that I almost lost my nerve to say what I so desperately
needed to tell her. I took a deep breath muscled up my nerve then said, “Jazz, I’m in
love… She has always been so close to me, yet so far away. She’s
always been like looking through a store window knowing exactly what
you want, but knowing that you couldn’t have your greatest desire…
I’ve never been able to tell her how I feel, but to me, she is the
most beautiful woman that I have ever seen, even as a girl she had my
heart… I want to marry her, but I don’t know how to ask her, even that
is complicated.” I saw her expression and could tell she was mad. She stood up pacing
around the room. I was waiting for her to throw something, that’s what
she had usually done when she was mad. I stood up and tried to calm
her down, but was punched in the nose for my effort. “WHO, who in the hell is she JACK?” She yelled at me as I bent over
from the surprising force of her punch. I sucked back my anger, not my anger at her but my anger at myself,
saying. “Who in the hell do you think it is,” I yelled back? I was
pissed, but luckily I had always been cool under pressure. “Probably some damn tramp you found at a bar or something!” “Damn-it Jazz,” I paused and the tears raced down my cheeks. “You know
you’re not the same girl who had my heart the first time I remember
looking at you.” I took a deep breath as my emotions overcome me and
my voice cracked. “Yeah it’s you Jazz, it has always been you…
Damn-it, I ache for you! (I then almost whispered) Every girl, I’ve
ever been with, it was you that I made love to. Go ahead, call me a
sick basterd, maybe I am, but I know what I feel, what I have always
felt. Let me ask you something. How do you tell your cousin that she
is the only girl in your dreams? How do you tell her that even on
Christmas day, I couldn’t enjoy being around my best friend because I…
because I love her so deep that not being able to hold her in my arms
was hell? Jasmine, you’re my reason. I am so sorry for the pain I have
caused you, that was the last thing I ever wanted to do. The last
thing I ever wanted to do was cause the most important person in my
life any pain. If you want to hit me again go ahead, hell I deserve
it.” I sat on the arm of my old couch with my head in my hands. I didn’t
hear a sound until she asked crying, “Do you really mean that?” I was still a little pissed and bleeding, but mostly felt a great
burden had been lifted off my shoulders. I then said sadly, “Jazz, I
really don’t think that’s something to kid about, do you?” I slowly
stood up walking over to her. She wasn’t the same girl as before. She
changed her whole demeanor. She wasn’t mad anymore but frightened. I
untied and pulled back her hood taking her into my arms. Holding onto
her tightly, not hurting her, but also letting her know I wasn’t going
to let her go unless she really wanted me to. She slowly wrapped her
arms around my waist. It felt so good to hold her, even with all that
had just gone-on between us, feeling her in my arms made it all worth
it. After a minute of nothing being said between the two of us she spoke
first. “Jack, come home with me. I need to show you something.” I was amazed but a little leery of the idea of going to her
apartment. What could she have to show me? “You think I should be over
there after what I have told you?” “That’s why I asked you over.” “Let me get my stuff. I’ll be right behind you.” That was a preview of Chapter 2. Let me know what you think on my

Steve Jobs replies to another email, but this time it’s personal…
Posted by Zee Follow Zee on twitter on May 15th, 2010
Gawker bloggers certainly know how to push Jobs’ buttons.
This time it’s actually the Gawker blog (rather than subsidiary Gizmodo) and its Contributing Editor Ryan Tate - although Tate didn’t disclose himself as a Gawker blogger till later on in the thread.
On Friday night, after watching one of the company’s new ads promoting the iPad as “revolutionary”, Tate decided to sit down with a cocktail (probably a few) and email Jobs into explaining just how revolutionary a closed platform could be.
A question about “freedom” and a reference to Bob Dylan (famously Jobs is a big fan) turned into a lengthy email thread and much of the same Jobs stubborness with a disappointing ending because well, pulling the “what have you done that’s so great” card is just…cheap.
Besides, Jobs should know better than to get into a discussion with a blogger (not that he knew he was one) late on a Friday night. Wonder what the Apple board would make of this.

The Valley of my Despair
Jazz and I went to bed then straight off to sleep. It was a restless
sleep. Several times in the night I woke up and went out to the
balcony to try and cool off but nothing seemed to cool me down, until
I filled the tub with cold water, and then put every ice cube in the
apartment in with me. I was finally able to go to sleep after the ice
bath. A restless night turned into a day of horror. Lying beside Jasmine on
my back I felt a great heat and a very hot trickle almost like
scalding water, but much hotter running down my right hand onto the
floor. I could hear a searing sound but couldn’t think whether this
was a dream or was this reality, even though my dreams and reality
lately have became almost intertwined, with the two rapidly becoming
the same state of mind. The heat had become almost unbearable, so I
opened my eyes and looked at my right hand. To my horror I saw that
the ring Clara had given me, had actually melted off of my finger, and
the gold was now eating a hole through the hardwood floor. I reached
down to scoop it off of the floor to keep it from going completely
through to the lower apartment. I could feel the intense heat but
didn’t feel any pain at all, neither was I harmed. I didn’t know what to do. I will be honest I panicked. I walked out of
our room and paced around like a madman. I couldn’t decide what to do.
So, I finally made my way out to the balcony. The sun was just now
coming up. I didn’t see anyone around me, so out of frustration and
fear I jumped off of the balcony landing hard. I rolled and rolled for
several feet. I stood looking at my body in the morning sunlight,
having only my shorts and a t-shirt on. “Everything seems fine, but I
can’t go back to them like this. Oh my god what do I do?” I didn’t get
any answers, so I started running, hoping no one could see me it still
being a little dark. I ran and ran. For some odd reason I didn’t get
winded and didn’t seem to be tired. I didn’t know where I was going,
but a couple hours later I realized I had ran to our property. I
roamed around seemingly endless until I found a large field. I
couldn’t concentrate on anything but I knew one thing for certain, my
family would never be safe with me around. I fell to my knees in
tears. I thought I had finally lost all will to continue. I began to
yell, “I give up. I can’t do this anymore. Pick someone else, someone
who doesn’t have a wife and children. They can’t be safe around me. Oh
god, please help me… help me.” I then heard someone walking up to me and to no surprise it was the
chief. He said, “So you have finally reached your breaking point. I
have to admit, you made it longer than I ever thought you would.” “Please, take this away from me. I can’t live like this anymore. I
have a son and a beautiful wife, with a little girl on the way. Why
can’t I just be a husband and father, that’s all I ever wanted?
Please, please sir, I can’t do this anymore.” He kneeled infront of me then said, “Son, you didn’t choose this, just
like none before you chose to be this way, it doesn’t matter what you
do this is you, but there is something you can do. It will not be easy
and it will be great pain you will suffer. However at the end of this
journey you will be able to control yourself and be stronger than you
ever dreamed.” “Please sir, I will do anything for that.” “You must be completely sure or I cannot take you.” “I am very sure, please sir, I beg you to take me. I am worthless in
this condition.” The chief did take me and he did train me, like I never thought
possible. In all I spent what would to the natural man be over a
hundred years in my solitude. The nights, if they’re where nights
would be spent thinking of my family and what I would say when I
finally saw them again. I worried many times that I had missed the
life’s of my Jasmine, Charlie and my Izzy Clare’s to come, but was
reassured they would only know the time in which I was on earth. It
would be only a few hours, which had passed by to them. So my training
went on and on. Many scars and just as many beatings I had to endure
through my years on this plain, I could only describe as preheaven,
but sometimes it was more hell than heaven. The only comfort I had was
I could talk to my departed family, but even though I loved them, I
still missed my family in Denver. Many journeys I had to trek testing
my limits and abilities. I was more than ever before, but didn’t know
when it was time for me to return. To me I had lived another life,
since I had lie beside my Jasmine, but my desire for her had never
died, nor did it ever wane. I had been taught so many things and now
possessed a confidence I never knew before my solitude. The chief and
I had our arguments and many times I wanted to go back, but I would in
no way allow him to know that. Nevertheless through it all I had come
to respect and even love him. Somewhere in what I think was my
eightieth year, I began to call him father. After that I saw a change
in him. Don’t get me wrong, he never let up on me and to be perfectly
honest I didn’t want him to, I had made a remarkable transformation
and I owed it all to him. One day the chief walked up to me, as I sat looking pointlessly down
the same hall he had taught me the first steps at controlling my fire
making abilities. “What are you waiting on, son?” I looked up at him and asked. “What are you talking about, father?” “You have completed your training, I can’t teach you anymore.” “But father, you have such wisdom, I can never learn everything you
have to teach me.” “Jack,” Him saying that surprised me, since I had been in training he
hadn’t called me by my name. If it wasn’t for my family occasionally
calling me, Jack, I don’t think I would have remembered it was in fact
my name. “Yes that is your name. Son it is time for you to go back
home. You have what you came here for. I hate to say this but I will
miss you.” “I can come back whenever I need you, father.” “Yes son, you can come back at any time, but this will be the last you
see of me,” he said and for the first time I saw tears in his eyes. I stood up, “No father, I need your guidance.” “I can’t teach you anymore,” He back handed me then said almost
without breath, “I have to go, Jack, and so do you, there is nothing
else for you to learn here.” He then turned his back to me, but I
could tell he was trying not to cry. Reluctantly and nervously, with a bit of a broken heart, I sent myself
to the same field I was when he had taken me to start my training. I
felt the bright light of the sun beaming down on me. I looked all
around, and the sights of the property reminded me of what I had left
behind so many years ago, in my mind. As I walked, I was reminded of how scared I felt almost constantly
before, but I would never admit it to myself and I wouldn’t dare admit
it to my loved ones. I knew what I had to do to straighten out the
confusion I had caused, but my paramount destination was to see my
Jasmine and my Charlie. Time hadn’t meant anything to me in such a
long time, so I don’t know how long it took me to walk back to the
apartment, but as I walked through that door I saw exactly what I had
spent all my time away or, my Jasmine and Charlie.
