I need to minimize weight of 1 litre of 8 bar hydrogen storage. The cost should be not more than 30 US dollars. Can you help me?

ChatGPT Certainly! I can help you explore some options to minimize the weight of a 1-liter, 8-bar hydrogen storage system while keeping the cost under 30 US dollars. Please note that the prices and technologies mentioned below are based on information available up until September 2021, and there may have been advancements or changes since then.

Type 1 Composite Cylinder: Consider using a lightweight composite cylinder made of carbon fiber reinforced with epoxy resin. These cylinders are commonly used for hydrogen storage. They offer high strength-to-weight ratio and can withstand high pressures. While they are relatively cost-effective, the specific cost depends on the specific manufacturer and market conditions.

Type 2 Metal Hydride Storage: Another option is to use a metal hydride storage system. Metal hydrides can absorb and release hydrogen gas, providing a safe and compact storage solution. They have a moderate weight and cost, making them a viable option for your requirements. However, their hydrogen storage capacity may be lower compared to other options.

Type 3 Composite Cylinder: Composite cylinders made of a plastic liner with carbon fiber reinforcement are another possibility. They are lighter than type 1 cylinders and may be more cost-effective. However, their operating pressure might be limited, so it's important to ensure they can withstand the required 8-bar pressure.

Type 4 Composite Cylinder: Type 4 cylinders consist of a plastic liner wrapped with carbon fiber and an additional protective layer. They are lighter than type 1 and type 3 cylinders, but they tend to be more expensive due to the advanced manufacturing techniques involved.

It's important to note that the cost of these storage solutions can vary depending on factors such as the specific manufacturer, market demand, and other associated components needed for the system. To get a more accurate estimate, I recommend reaching out to hydrogen storage system manufacturers or suppliers who can provide up-to-date pricing information.

Additionally, you may need to consider safety regulations and certifications for hydrogen storage systems, which could affect the final cost and weight of the system.

Remember that the hydrogen storage options mentioned above are suggestions based on general knowledge, and it's always a good idea to consult with experts or professionals in the field to determine the most suitable solution for your specific requirements

ahmadindrasiswantara@gmail.com find al quran saying they have heart but not used to undertand Here is a verse from the Quran that talks about people who have hearts but do not use them to understand:

"And they have hearts with which they do not understand, and they have eyes with which they do not see, and they have ears with which they do not hear. Those are like livestock; rather, they are more astray. It is they who are the heedless." [Quran 7:179]

This verse highlights the importance of using our hearts and minds to gain understanding and insight, and warns against being like those who are heedless and fail to comprehend the signs of Allah around them.

ahmadindrasiswantara@gmail.com find al quran saying Allah hates who say but never act Here's a verse from the Quran that talks about Allah's dislike for those who say but do not act:

"Say, 'Do you order righteousness of the people and forget yourselves while you recite the Scripture? Then will you not reason?' And seek help through patience and prayer, and indeed, it is difficult except for the humbly submissive [to Allah], Who are certain that they will meet their Lord and that they will return to Him." [Quran 2:44-45]

This verse emphasizes the importance of practicing what one preaches and of being humble and submissive to Allah. It warns against hypocrisy and forgetting one's own responsibilities while urging others to do good.

ahmadindrasiswantara@gmail.com find al quran saying Allah hates who say I'm sorry, my previous response was incorrect. There is no Quranic verse that specifically states "Allah hates those who say but do not act". However, there are several verses that mention the importance of action and deeds in addition to words, and warn against hypocrisy.

One such verse is:

"O you who have believed, why do you say what you do not do? Great is hatred in the sight of Allah that you say what you do not do." [Quran 61:2-3]

This verse highlights the importance of practicing what one preaches, and warns against saying things that are not backed up by action. It emphasizes the importance of sincerity and integrity in one's words and deeds.
