Using PET bottles to cast low-weight and cost-effective reinforced concrete voided slabs

Empty bottles (polyethylene terephthalate – PET) are available in abundance, whether as waste or new, getting them is very cheap or without cost and using them in construction is an excellent solution to a large and very widespread environmental problem.

Solid reinforced concrete slabs are expensive and heavy in weight and consume more steel reinforcement and concrete materials than voided concrete slabs of equal strength because the middle part of the slab depth is useless for most of it, except to give the slab a depth between the tensile and compressive, lower and upper, depths.

Voided concrete slabs cast on site is a common technique. However, its production requires the use of forms or shapes materials specially made for the casting of voided slabs and it is of medium cost and freight.

Therefore, after laying the reinforcing bars, it is more expedient to throw empty PET flasks to fill the spaces between the steel before or during the pouring of concrete. Flasks of any types and sizes can be used in an easy manner that does not require much care other than to restrain their movement during casting

استخدام قوارير فارغة لصب بلاطات خرسانية مسلحة قليلة الوزن والتكلفة

القوارير الفارغة (بولي إيثيلين تيرفثالات – بي ئي تي) متوفرة بكثرة سواء كنفايات او جديدة والحصول عليهم رخيص جدا او بدون تكلفة واستخدامهم في البناء يشكل حل ممتاز لمشكلة بيئية كبيرة ومنتشرة جدا.

والبلاطات الخرسانية المسلحة المصمتة تعتبر مكلفة الثمن وثقيلة الوزن وتستهلك تسليح فولاذ ومواد خرسانية اكثر من البلاطات الخرسانية المفرغة المساوية لها في القوة لان الجزء الوسطي من عمق البلاطة لاجدوي من غالبيته سوي منح البلاطة عمق بين سطحي الشد والضغط العلوي والسفلي.

والبلاطات الخرسانية المفرغة المصبوبة في الموقع هي تقنية اعتيادية منتشرة. ولكن انتجها يتطلب استخدام مواد مفرغة او خفيفة الوزن مصنوعة خصيصا لصب البلاطات المفرغة وهي متوسطة التكلفة والشحن.

لذا الاجدي بعد ربط شبكة التسليح القاء قوارير بي ئي تي الفارغة لملء الفراغات بين الفولاذ قبل او اثناء صب الخرسانة. ويمكن استخدام قوارير من اي الانواع والاحجام وبشكل لايتطلب عناء في التوزيع سوي للحد من حركتهم اثناء الصب

Boxed Ship Mast

A new design concept for sailing masts. I called it “Boxed Mast”. It is structurally and economically more sound than the conventional mast design; and it is also much better than the tripod design and the one used in The Maltese Falcon.

It also provides better energy saving and safety from sinking and weight and materials reduction.

Costa Concordia Wreck Removal Alternative Proposal

Costa Concordia wreck

Costa Concordia Wreck Removal Alternative Proposal

I think the idea of moving the wreck of Costa Concordia to upright position on a newly erected sub-sea platform before floating is not the best solution. It is time-consuming and materials-consuming and it is by far more expensive. And definitely it will be impossible to keep it upright during the towing phase.

It would have been better to float and tow it in its tilted position because keeping a damaged ship upright after shifting and distorting its center of gravity and after its bottom cavity was destroyed is clearly huge task.

I suggest a much easier and cheaper approach, as follows:
1. Make many small light weight tanks
2. Sink equal numbers of these tanks on both sides along the length of the wreck
3. Tie each tank with at least three tanks on the opposite side of the wreck with steel cables passing underneath the wreck
4. Tighten the mesh of steel cables to bring the opposite tanks as close as possible
5. Start pumping the water out of the air-tight tanks simultaneously to make them float and lift the wreck
6. Add more connected tanks as much as needed on both sides of the wreck to raise the load substantially
7. While it is afloat and still on its tilted position it is possible to tow the wreck away to a ship dismantling yard

The current operation i as follows:

1- The tieback chains prevent the wreck from sliding

2- Meanwhile fabrication and then installation of sub-sea platform to support the ship

3- Install the flotation tanks on the port side by welding to framework which was previously attacked to the hull

4- Pulling machines are connected to pulling points on the subsea platform

5- With flotation tanks and pullers in place, we can begin to roll the ship upright

6- The TitanMicoperi plan for the salvage of the Costa Concordia

7- resting on new platform

8- attaching floating tanks

9- floating the wreck

10- towing

New All-in-One Desktop Computer Design

New All-in-One Desktop Computer Design

New All-in-One Desktop Computer Design

I propose to all entrepreneurs a new design for tower desktop; called “Top-Tower form”, (T.T.). The end product shall have all the performance of a versatile, upgradeable, powerful and affordable desktop together with many features of a compact laptop.

Desktop Workstation New AIO Design Details

It is very efficient, practical, economical and attractive. It shall solve many issues at once and will become the best alternative to conventional desktop and laptop in business and personal uses.

Since all desktops are now using slim monitors (LCD or Plasma) then there is a chance to have a design whereby the monitor could be integrated and forms a removable part of tower case.

Not like Apple’s iMac computer models released from 2004, and other All-in-One designs, where all PC components are integrated behind an LCD screen. The new design shall do the opposite; by mounting a changeable slim monitor to one side of full-,mid- or mini-tower with a top handle.

The monitor shall act as a slightly tilting side cover to the case, or the case shall have a trapezoidal x-section. All the components of the front panel may be moved below the monitor which will transform the side panel to become the new front panel. You can make the conventional PSU slimmer and/or just fix it vertically to reduce case depth.

You can initiate a standard trend whereby new tower cases shall have the monitor as a customizable integral part. A separate fold-able or detachable keyboard with an additional touch pad may be added as optional, or just keep a conventional mouse.

Also, you can add a single-leaf or two-leaf sliding or hinged cover to the monitor; plus a single Y-shaped power cord.

An alternative to this design is to make the monitor fixed on adjustable mounts on the left- side of ordinary case. Both designs can be applied with the second as modification for the present models of tower cases.

Hard disks; expansion cards; and optical drives shall be mounted and ejected just from outside of the new front panel below the monitor without opening the case, with the same mechanism used with optical drives in laptops.

I expect these designs will be very attractive and useful for the majority of computer owners who cannot afford to buy a laptop or prefer using a desktop.

The new designs have the following features:
1- occupy less space;
2-shorter cables;
3- changeable monitor;
4- compact and portable;
5- maintain component flexibility;
6- lesser materials and total weight and
7- less expensive in transport and upgrading.
It can go together with manufacturing conventional Desktop Tower Cases.

Major companies realized that the conventional tower desktop needs new design to solve a number of important difficulties. So they came up with the AIO monitor concept but the concept behind the design was based on integrating the case components into the back of the monitor. By doing so, they sacrificed important elements as of upgradability and AIO became only a immobile laptop. It failed.

Now computer manufacturers reversed the concept of AIO monitor and integrated the monitor onto the desktop tower case to create AIO case; but did not solve the issues of expansion cards, monitor positioning and the access to the motherboard. This failed also.

I did not try to improve the AIO case but my design is independent fresh approach. My design offers a number of important advantages to the monitor, motherboard, hard disks, expansion cards, upgradability, maintenance, keyboard, weight, aesthetics and cost.

I am posting to hear form someone interested in manufacturing this deign under patent license.

Wicked So-called Skilled Workers Endemic

…

Wicked Skilled Workers Endemic

Beside massive scale western plunder and state official  corruption, the causes of poverty and sickening economy are the low qualities of manual and “skilled” workers in many underdeveloped countries.  They got no tools; have flimsy experience; illiterate; cheats; liars; careless; vulgar; tricky; destructive; stupid; and fake.

People better avoid owning a lot of stuff or properties that will make them in need for those trouble makers.

I hate the day when one of these access my property and pretend to do repairs and improvements. I better get rid of that thing or not to have at all.

I hate to have a house; business; car; or appliances here! If I cannot do it myself then to hell with it.
They cause headache and stress; and of course take your money without any good reason.
