The Mag-Beam propulsion concept was developed by Robert Winglee and his fellow researchers as a means of propelling quick interplanetary shuttles without mucking around with rockets and  Dell Latitude D620 Battery. Basically it’s a big plasma rocket turned into a big plasma gun, that fires a fast, hard ion-beam at a magnetically ensheathed shuttle vehicle. This gives the shuttle a big shove and sends it on its way – to be slowed down at the destination by another Mag-Beam, or a bit of adroit aerobraking if it’s slow enough.

Problem is the Mag-Beam wants a lot of juice to do the job – for example, a 20 ton shuttle being accelerated to 20 km/s needs a 300 MW Mag-Beam firing at it for about 4 hours, which is a lot of Dell U4873 Dell D5318 battery mass (3,000 tons at 400 W.hr/kg of battery.) Once the beam has fired the massive battery pack can be recharged via solar power over a few weeks or days before the Mag-Beam is needed again. But is the battery pack needed at all?

Geoffrey Landis designed a Solar Power Satellite that beams 1 GW to the ground @ 33% efficiency and it massed just 1,300 tons which means its in-space power output is 3 GW – ten times the power needed by the Mag-Beam for Dell TC030 Dell PC764. Thus an in-space SPS power source for a 300 MW Mag-Beam need only weigh 130 tons.

That’s a mass that could be launched in one piece by an Energia or Saturn V class launcher – like the new Ares launchers for NASA’s Return to the Moon. To do everything the Mag-Beam is required to do the power has to be delivered to multiple Mag-Beam plasma-gun stations.

What made Landis’ SPS so light was that it remained in an orbit perpetually pointed at the Sun, so there was no need for a rotating power transfer collar from the array to the rectenna, and the same reflectors used for power gathering act as rectennae for power transmission in the Landis design. To keep that simple design for Dell 8N544 Dell RN873, and power Mag-Beam stations in multiple locations, Power Relay Satellites – really just microwave wave-guide horns for changing a beam’s direction – might be needed.

Or we might just bite the bullet and have a rotating connection between array and station. Both add mass, but it’ll be a LOT less than 3,000 tons of Latitude D400 Battery. Plus PRSs can point at rectennae beaming power up from the ground to transfer back down to the ground at another location, allowing a PRS to do multiple roles and make money transferring power to areas of peak demand on the ground.

Aside from propelling shuttles to Mars and elsewhere a Mag-Beam can also boost a sub-orbital vehicle ( a modified Virgin Galactic SpaceShip, for example) to orbital speed in Inspiron E1405 Battery. The power required maybe higher, but as a shorter burst. If the sub-orbital vehicle can boost to a horizontal speed of ~ 1 km/s, then another 6.8 km/s is needed for low orbit. At an acceleration of 20 m/s^2 that’s a boost for 340 seconds, just under 6 minutes. In energy terms it’s the equivalent of 120 minutes of a 300 MW beam. Perhaps the higher power can be supplied from the ground?

Experts Call for home power outlet qualified products to choose 3C logo(B)

Beijing Quality and Technical Supervision, Senior Engineer, Beijing Quality and Technical Supervision of Quality Supervision Department, the former Director of Hede Xiang believes that the current power plugs and sockets and switches pass rate is generally low, “in 1999 in Beijing for the first time on the market 60 kinds of product sampling, and only five kinds of products(f4809a) qualified, a pass rate of 8.3%. in which Beijing had inspected eight kinds, including the Branch can come there are four kinds of qualified, including Bo, while the field is only 1 species of 52 qualified; to Beijing in 2004 City, also on the 80 kinds of mobile socket converters carry out spot checks, qualified nine kinds, with a pass rate to 13.24%, but still low. ” Hede Xiang said: “Over the last two years, some raw materials prices, such as plugs and sockets used by Ling, zinc and copper prices higher, a time of high Qiba Wan yuan per ton of material, some manufacturers in order to reduce the cost of an ordinary copper instead, it on the impact on product quality. ”

China Electrical Equipment Certification Board (CCEE), former director of the Office of researcher-level senior engineer called on people to use with the pro-Shun “3C” mark of qualified products. Product certification is widely used around the world product quality supervision and management and evaluation assessment approach, the pro-Shun said: “The power plugs and sockets and switches must CQC (China Quality Certification Center Electrical Equipment) certified qualified, wearing 3C signs, in order to the factory sales pavilion zd8000 battery, This is the product of the access card to enter the market is a product based on market surveillance and investigation to ensure that the bulk of enterprises to provide stable, continuous qualified products. ”

As the power plugs and sockets and switches the brand companies can come to Bo, Beijing Branch has always been dedicated to market stability, qualified to meet the 3C compulsory certification of quality products; they also become a space flight using electronic power converters fixed procurement enterprises, “Shenzhou V”, “Shenzhou VI” has contributed to the success of flying. FENG Song-yun, chairman of the analysis of characteristics of the safe use of electrical appliances, said: “Most modern electrical appliances used in high-voltage integrated circuits are afraid to shock, in addition, the whole problem easy to difficult, issues are generally the interface, the electrical power supply interface does not directly affect the reliability for laptop battery and hp battery rechargeable is the key to the safe use of electrical appliances. Bacheng unqualified power outlet converter is a great a security risk. “

With the popularity of household appliances, electrical fires have accounted for 28% of the total number of cities around the fire, fire losses accounted for more than 40% of the entire loss of electrical goods is becoming a city of fire first “killer”, to the people’s lives and property caused by serious harm. According to the survey pavilion zv5000 battery, electrical interface, and power interface being exposed lead to ignition is the main reason for the fire.

Recently, Beijing held a portal to a “modern electric appliances, application and safe use of electricity,” the exchange will be invited to the domestic power socket and plug converters well-known enterprises in the Beijing Branch can come to Bo Electronic Technology Co., Ltd. Chairman and Managing Director FENG Song-yun and others talked about power supply interface, the safe use of socket converter.

Holly Gates ran across our item raising the possibility of solar-cell covers to help power E Ink machines. But what about an e-reader that relies entirely on energy from the sun or other light sources and Pavilion dv6000 Battery?

None other than Holly has built a demo model for battery, and here’s part of the write-up from the Greener Gadgets Design Competition 2008:

“Snippy is an ultraportable handheld electronic viewer for textual and graphic information which harvests operating energy from the sun and transparently links to other Snippys in the area to share content. This solar networked information propagating paper-like display brings together the daylight readability and extremely low average power consumption of an electronic paper display to Toshiba PA3356U-1BRS, a solar panel to gather energy from light, and a Bluetooth radio interface.

“The readability and optical quality of an E Ink display are unparalleled, especially in high light conditions like outdoors during daylight hours for Toshiba PA3383U-1BRS. The 800×600 6″ diagonal high reflectivity screen used in the device offers 166ppi resolution at 16 gray levels , which translates to crisp, well rendered text and detailed grayscale images with a paper-like look. A high quality device of this nature can reduce greenhouse gas emissions by 128kg and fresh water usage by 3543 liters per year by displacing the paper used for ephemeral content by a typical reader…

“…Laminated metal/organic construction, design for repairability and long service life, and mostly recyclable components minimize the life cycle ecological impact of the device…”

So, gang, what do you think—about the solar-power aspects of Snippy and the ergonomic angles? What would it take for you to buy such a machine not Toshiba PA3384U-1BRS? How much would you pay? And might the idea fit into One Laptop Per Child or similar groups in some ways? Others, too, have been thinking solar. Maybe Holly Gates and Martin Woodhouse could join forces (that’s his design you see to the left). One thing they have going for them is that E Ink will be common in the near future in a bendable form, which could make units even smaller and lighter, not just more rugged. I wonder, too, if future E Ink might have even lower power requirements than the present variety sucn as Toshiba PA3395U-1BRS.

D620 update : Dell latitude D630

The Latitude D630 is Dell’s latest update to the Dell Latitude D620 Battery, a light-weight business class machine. It was in May that Dell announced its intent to implement the new technologies provided by Intel’s new mobile computing platform codenamed Santa Rosa, and known as Centrino Duo. In short the latitude D630 is a real powerhouse and unbeatable value machine.

Dell latitude D630 Spec

• Processor : Intel? Core? 2 Duo T7250 (2.00GHz, 2M L2 Cache, 800MHz) Dual Core
• Media Bay Devices : 24X CD-RW/DVD w/ Cyberlink PowerDVD?
• Memory: 1.0GB, DDR2 SDRAM, 1 DIMM
• Hard Drives: 80GB2 Hard Drive, 9.5MM, 5400RPM
• Graphics: Intel? Integrated Graphics Media Accelerator X3100
• Battery: 6 Cell Primary latitude D630 Battery
• Wireless LAN (802.11): Dell Wireless? 1395 802.11g Mini Card
• Dimensions (LWH): 13.3 x 9.3 (10.3 with extended battery) x 1.3 inches
• Screen size diagonal) 14.1 inches
• Battery code : Dell TC030 Dell PC764

The D630 sports the same ergonomics that we loved about the Dell Latitude D620 Battery: a pointing stick, dedicated volume and mute buttons, and a roomy, spill-resistant keyboard with minimal flex. That’s near the outer limit for a thin-and-light, though just 0.4 pound heavier than the Lenovo ThinkPad T61. Also The notebook also incorporates a thorough set of features for business — including corporate-level security measures and optional WWAN — for a lower price than competitors such as the Lenovo ThinkPad T61.

Includes a 14.1in display with a 1,440 x 900 native resolution that’s a significant improvement over the 1,280 x 800 often found on displays of this size. The latitude D630 can paly almost the vedio and game clearly with the 9cells battery as Dell U4873 Dell D5318.The screen facing the sun while indoors. Easily readable. . The movie looked good from most horizontal angles, but shifting the LCD up or down resulted in a distorted picture.

The D630’s 2.2-GHz Intel Core 2 Duo processor and 2GB of RAM enabled the system to produce a strong PCMark05 score of 4,568. That’s slower than the ThinkPad T61 we tested. The design behind this is most likely for the battery use and people that need a faster processor (multimedia users).The machine is extremely quiet, the fan hardly goes into full blast, even with the CPU at 100 percent.

One especially nice perk is the included Wi-Fi Catcher (activated by pushing the Wi-Fi switch to the far right as Dell Latitude D610 Battery), I did not have enough time to test it with the screen at a medium level but Vista tells me I can safely say it can push a little over six hours with Wi-Fi. If you get the Media Bay battery to go along with the nine-cell, I would venture about 7.5 or more hours. Of course, this is assuming you are using it for lightweight programs and you have 1GB or more of RAM.

Battery life with the primary 6-cell Dell laptop Battery was fairly standard stuff, and you can expect between two to three hours battery depending on how you use the notebook. But Compaqr to Dell Latitude D820 Battery  Dell Latitude D630 included a nine-cell battery  that extends about 2.5cm in front of the system. The extended battery served the Latitude well in our taxing DVD battery-drain test, where it held out for 4 hours 45 minutes.

In all, dell latitude D630 is Dell’s latest update to the latitude D620, so it has better performance. It is enough competent for your daily work and study. Dell’s incredible website with full instructions about servicing the laptop. All of the diagrams give me so much confidence installing more memory (or if I need to replace the drive).

Buying rechargable Digital Camera battery is always far better than purchasing the disposable ones. However, it’s still not a perfect method. It helps so that you’re throwing away less batteries, but at the same time you’re still plugging something into the wall and using your electricity to charge the batteries. Instead of plugging a Sony laptop battery charger into the wall, this ReNEW would allow for your rechargable batteries to become even more eco-friendly.

This ReNEW charger allows for you to just drop the Toshiba laptop battery through the top slot and once the battery is all charged it will drop out of the bottom. On the back of the unit is a solar panel that is the resource of the power pumped into your batteries. The charger can either sit on a tabletop like a picture frame or you could use the suction cup to attach it to a window. It’s a fantastic design, but sadly Canon digital camera battery is still a concept.

Check out the reNEW Solar Battery Charger concept that does come across as some sort of decorative frame which hangs out on your window through the use of a suction cup, where laptop battery will sit pretty on any table. When you take a closer look at it, you will realize that this is a solar charger for rechargeable batteries, so hopefully neat designs such as these will help move more people’s hearts and wallets to lean towards the green side of things. All you need to do is slide batteries down the back of the frame straight into the protective charging pouch and you’re good to go. Too bad this is but a concept at this point in time.

Lithium-ion Battery Life and Death

Lithium-ion laptop battery packs are expensive, so if you want to make yours to last longer, here are some things to keep in mind:

• Lithium ion chemistry Sony pcga bp71 prefers partial discharge to deep discharge, so it’s best to avoid taking the battery all the way down to zero. Since lithium-ion chemistry does not have a “memory”, you do not harm the battery pack with a partial discharge. If the voltage of a lithium-ion cell drops below a certain level, it’s ruined.
• Lithium-ion batteries age as Dell inspiron 6000 battery. They only last two to three years, even if they are sitting on a shelf unused. So do not “avoid using” the battery with the thought that the battery pack will last five years. It won’t. Also, if you are buying a new battery pack, you want to make sure it really is new. If it has been sitting on a shelf in the store for a year, it won’t last very long. Manufacturing dates are important.
• Avoid heat, which degrades the Toshiba pa3465u-1brsbatteries.

Exploding Batteries

Now that we know how to keep lithium-ion batteries working longer, let’s look at why they can explode. Several news reports in the past six months describe laptops with lithium-ion laptop battery that caught on fire.

If the Toshiba pa3107u 1brs battery gets hot enough to ignite the electrolyte, you are going to get a fire. There are video clips and photos on the Web that show just how serious these fires can be. The CBC article,”Summer of the Exploding Laptop,” rounds up several of these incidents.

When a fire like this happens, it is usually caused by an internal short in the battery. Recall from the previous section that lithium-ion cells contain a separator sheet that keeps the positive and negative electrodes apart. If that sheet get punctured and the electrodes touch, the battery heats up very quickly. You may have experienced the kind of heat a Toshiba pa3384u 1brs batterycan produce if you have ever put a normal 9-volt battery in your pocket. It a coin shorts across the two terminals, thebattery gets quite hot.

In a separator failure, that same kind of short happens inside the lithium-ion evo n600c battery. Since lithium-ion batteries are so energetic, they get very hot. The heat causes the battery to vent the organic solvent used as an electrolyte, and the heat (or a nearby spark) can light it. Once that happens inside one of the cells, the heat of the fire cascades to the other cells and the whole pack goes up in flames.

It is important to note that fires are very rare. Still, it only takes a couple of fires and a little media coverage to prompt a recall.
