The Double Bubble D8

One of the advanced design concepts – the D8 or "double bubble" – is now a subscale model being tested in a wind tunnel at MIT. The design, developed for NASA by a team led by Massachusetts Institute of Technology, has a very wide fuselage to provide extra lift, low-swept wings to reduce drag and weight, and engines sitting above the fuselage and aft of the wings to block some noise from reaching the ground.

(Re)Charge It! USB Batteries Kick-Start Dead Gadgets

Running out of power in the middle of an important text, video game or picture-taking opportunity is a drag – and finding a place to charge up your USB gadgets is not always easy. The "Continuance rechargeable battery" concept would rescue all of your brain-dead gadgets quickly and easily, letting you finish what you have  started.

The batteries in question are the same size as traditional batteries and can be recharged in the same way. But they also feature a USB port on the side, letting you plug that gadget in for a quick jolt of energy whenever you need it.

Of course, these batteries probably won’t hold much power, but when you are in an emergency situation (whatever you might define as an “emergency”) even a little bit of power can be a huge help. Designed by Haimo Bao, Hailong Piao, Yuancheng Liu & Xiameng Hu, Continuance is an iF Concept Design entry for 2011.

How To: Install Windows 7/Vista From USB Drive [Detailed 100% Working Guide]

How To: Install Windows 7/Vista From USB Drive [Detailed 100% Working Guide]

This guide works 100% for Vista & Windows 7 unlike most of the guides out there. I have seen many sites/blogs that have “Install Vista from USB guide” but either with incomplete steps or not working guide. I have also seen some guides that don’t’ use proper commands in this guide. After spending many hours I have come up with this 100% working guide.

I just did this method on one of my friends machine and installed the new Windows 7 BETA. The main advantage is that by using USB drive you will be able to install Windows 7/Vista in just 15 minutes. You can also use this bootable USB drive on friend’s computer who doesn’t have a DVD optical drive.

The method is very simple and you can use without any hassles. Needless to say that your motherboard should support USB Boot feature to make use of the bootable USB drive.


*USB Flash Drive (Minimum 4GB)

*Windows 7 or Vista installation files.

Follow the below steps to create bootable Windows 7
/Vista USB drive using which you can install Windows 7/Vista easily.

1. Plug-in your USB flash drive to USB port and move all the contents from USB drive to a safe location on your system.

2. Open Command Prompt with admin rights. Use any of the below methods to open Command Prompt with admin rights.

*Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.


*Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.

3. You need to know about the USB drive a little bit. Type in the following commands in the command prompt:

First type DISKPART and hit enter to see the below message.

Next type LIST DISK command and note down the Disk number (ex: Disk 1) of your USB flash drive. In the below screenshot my Flash Drive Disk no is Disk 1.

4. Next type all the below commands one by one. Here I assume that your disk drive no is “Disk 1”.If you have Disk 2 as your USB flash drive then use Disk 2.Refer the above step to confirm it.

So below are the commands you need to type and execute one by one:







(Format process may take few seconds)



Don’t close the command prompt as we need to execute one more command at the next step. Just minimize it.

5. Next insert your Windows7/Vista DVD into the optical drive and check the drive letter of the DVD drive. In this guide I will assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about it).

6. Maximize the minimized Command Prompt in the 4th step.Type the following command now:

D: CD BOOT and hit enter.Where “D” is your DVD drive letter.

CD BOOT and hit enter to see the below message.

7. Type another command given below to update the USB drive with BOOTMGR compatible code.


Where “H” is your USB drive letter. Once you enter the above command you will see the below message.

8. Copy your Windows 7/Vista DVD contents to the USB flash drive.

9. Your USB drive is ready to boot and install Windows 7/Vista. Only thing you need to change the boot priority at the BIOS to USB from the HDD or CD ROM drive. I won’t explain it as it’s just the matter the changing the boot priority or enabling the USB boot option in the BIOS.

Note: If you are not able to boot after following this guide means you haven’t set the BIOS priority to USB. If you got any problem in following this guide feel free to ask questions by leaving comment.

Lamp lights without a socket or sun!

 the makers of the Zen light, still in the nascent stage of development, actually claim that it does not need any external source to light itself. It actually depends on the “magnetic engine” that the lamp is already equipped with. The way this lamp functions is both simple and intriguing. The magnets placed inside the lamp make sure that they create enough force to keep the lamp spinning. Now this spinning, in return, powers a series of LED diodes. The power thus generated helps the lamp light up without any external assistance.

The designs shown so far are sleek and very contemporary.
Just while penning this down, here is an afterthought. Since the idea is so simplistic and basic in nature, could we not adapt it (in its cheaper version of course!) and use it to light the kerosene-lit, forest-covered areas that still darken the world map of the 21st century.

Indian students create kinetically-powered, junk-made washing machine

Designed by a team of two students, Sourabh Siyal and Tushar Agarwal, from Christ College, Bangalore, India, Eco-wash is a junk-made washing machine that does laundry for you on mechanical and kinetic energy. The duo utilized a discarded plastic bottle and a pulley to create their version of an eco-friendly machine. With a plastic bottle working as a box for washing clothes, an attached pulley helps ease the washing process.
Sourabh Siyal, team member, says…

Our idea is to do away with electricity and come up with an alternative. The washing machine can be useful in big textile industries. We’re planning to give our idea to one of India’s leading garment manufacturing units.

Fluid-submerged data-center servers promise 95% cut in energy usage

Most data centers have been cooling there servers using air cooling method. While the method is used widely, it is not very cost-friendly and green because many times the cooling cost is almost equivalent or even higher than the equipment cost.

To solve this problem a company called Green Revolution Cooling has introduced a radical new approach to cooling via a liquid dielectric coolant in which the data server can be submerged.
The greatest advantage of this technology is that it reduces cooling energy use by 90-95 percent and the total energy usage by almost 50 percent. The fluid used for the cooling system is a clear, odorless, non-toxic, and low-cost non-conductive white mineral oil that can hold 1200 times more heat than air when the server is submerged in it.

There are certain visible advantages of the fluid cooling system over traditional air cooling methods:

•With liquid cooling environment servers do not gather dust on them and they remain virtually dust-free.

•There are no fans that can wear and tear and fail to work leading to server heating. Therefore, the servers’ life is indirectly increased.

•Liquid cooling makes it easy to recover the heat produced and use it for some other useful purpose.

•Overheating of the server and failure is minimized because the liquid cooling is more controlled than air cooling method.

•The use of digital technology is increasing every day and therefore the fluid cooling method gives a greener and energy efficient choice to maintain the server cloud than the air cooling system.

•Servers cooled with mineral oil are more safely overclocked therefore the same chips are run at a higher speed.

According to the manufacturers,

Our system will cool up to 100kW in a 42U rack in its current configuration. This is equivalent to an air-cooled system near 120kW since nearly 20kW of that 120kW would be used by server fans. Our system offers orders of magnitude better convective cooling than an air-cooled system and thus can handle higher densities.

The cost-wise advantage of this system is also noteworthy. For a brand new data center the upfront cost can be drastically reduced with smaller generator, smaller UPS, no CRACs, no chillers and no need for raised floor. Add to it the low energy usage and high performance and it is a complete win -win situation.

The liquid cooling system for data servers is surely a next generation green technology.

Minix aerodynamics breakthrough increases fuel efficiency by about 6%

Fuel efficiency and emissions are the two contexts in which aviation industry has invited bad press in perpetuity. A fair bit of scaling down can be expected in all of this with the Minix wing tip device. Developed by French aeronautics teacher Christian Hugues, the equipment which sits on the tip of an aircraft wing is a replacement for vertical and tilted winglets. Its aerodynamic design comprises cylindrical shape which reduces the drag by smoothening out and negating the high-pressure spiral vortices that form when a plane is in motion.
The Minix wing tip can be retrofitted to any aircraft wing. Apart from reducing the drag, the Minix system produces increased lift at the wing tip, which is especially useful during landing. Most importantly, according to Hughes the Minix wing tip is cheaper than a traditional winglet and on a recent prototype testing it showed a 6% gain in drag efficiency at Mach 0.8 which is the typical speed of an airliner.
