If you’ve ever wondered, “How long will a helium-filled Graphene balloon stay afloat?” then you aren’t alone. The answer is surprisingly long, at least for a Graphene balloon. This article will explain how Graphene works and answer some frequently asked questions about this innovative material.
It is hard to predict how long a helium-filled graphene balloon will stay afloat, but it’s not impossible to imagine! One possible solution is the use of bubble foam. A complex 3D network of carbon nanotubes and Graphene is called aerographene and has the highest volume of air and a density that is slightly lower than helium.
The researchers attached the Graphene to a silica glass membrane. They then measured the volume of Graphene under pressure. The bulge in the graphene material is the same as that of ordinary graphite. Using a laser, they can then calculate the mass of the Graphene. This method could also be used for tiny weighing devices and pressure sensors.
While scientists do not yet know the answer to that question, they take steps toward that goal. To make this technology a reality, researchers at Cornell University developed a method that would allow them to produce sheets of Graphene. The researchers fashioned a small bottle with a graphene sheet stretched over the gas. The graphene sheet remained stable under high pressure. This research was published in the journal Nano Letters.
Graphene is an excellent material for balloons, as it conducts electricity and heat while remaining lightweight. Although it’s stronger than steel, Graphene is also lighter than air, which means a helium-filled graphene balloon would stay afloat much longer. Although Graphene is more potent than helium, it’s not a suitable replacement for helium.
However, the main challenges for large-area nanoporous graphene membranes are their production and transfer and their engineering performance. But it’s worth noting that the nanoporous graphene membranes can reject two to three orders of magnitude more water than commercially available RO membranes. If successful, such membranes would have the ability to purify water, fuel cells, and various other chemicals.
What’s more, the size of a helium-filled graphene balloon will likely be tiny. The minimum gasbag radius is about 2.5 times the density of the membrane. However, this doesn’t mean it’s impossible. Further, Graphene and bubbles may allow tiny balloons, which might be more practical for everyday use. There is another possibility – the use of helium in the form of bubbles or Graphene.
A helium-filled graphene balloon will remain afloat as long as the balloon is sealed and connected to long channels. Its unique properties make it an excellent material for studying the dynamics of gas flows at the nanoscale. The material’s outstanding properties are also helpful in engineering new types of sensors and devices. For example, Graphene can be used to detect the composition of gases.
However, hydrogen is a non-recyclable gas that will leak out of the balloon. Hydrogen will eventually escape because it is non-recyclable, and the whole contraption will be disposed of. This would be extremely harmful to the environment. The Hydrogen cocoon project hopes to solve this problem by developing a small-scale prototype that can be tested in the laboratory before a more extensive version is manufactured.
In previous research, the length of a helium-filled graphene balloon has been estimated to be up to a hundred kilometers. The rope must be more than a hundred kilometers long to increase the balloon’s height. In addition, the length of the string should be longer than the diameter of the graphene balloon.
The cost of the balloon is a crucial issue. Developing a helium rocket will cost PS80 billion and PS11 billion, while the cost of an airship would cost more than twice that much. This technology would need ten to twenty years to become practical. However, the downsides of a helium rocket are negligible, and the social and environmental impact of the project would be minimal.
Although helium and hydrogen would be much lower than a helium-filled graphene balloon, they would still need to be re-inflated every flight, making the total cost around PS1.4 billion per year. These costs would increase with the cost of helium and hydrogen. It would take five to ten years to deploy a hydrogen-filled balloon fully and require extensive investment in supply lines.
The helium gas inside the balloon will contract at temperatures between 45 and 50 degrees Celsius. The balloon will shrink and lose helium at these temperatures. Once the balloon is moved to a warmer area, it will revert to its entire shape. However, the temperature in the room will affect the helium balloon’s float time. It should not be inflated too close to the event as it will quickly lose its helium.
The theory behind a graphene-filled balloon is not entirely new. The principle that Graphene is a gas sphere is not precisely new. But Graphene is a brittle material with low shear strength. So, a graphene balloon would need to be inflated with a gas that would displace some of the air in its body. A gas that does this is hydrogen, which is relatively inexpensive and quickly produced in a laboratory.
Graphene sheets are used as seals in microscopic wells of silica glass. These sheets are held in place by van der Waals forces – atoms that make things sticky on tiny scales. Researchers then varied the pressure inside the wells to see how well the Graphene could retain the gas. As they altered the pressure inside the wells, the membranes either bulged inward or outward. When appropriately sealed, the graphene sheets were utterly impermeable.
Graphene can conduct electricity and heat. Its thickness means that it can be stronger than 200 percent steel and lighter than air. As a result, researchers have hypothesized that Graphene could eventually replace helium in balloons. But while Graphene can replace helium, the researchers at MIT have come to a definitive answer.
Hydrogen permeation is dependent on pressure. Monolayer graphene exhibits no hydrogen permeation under prolonged exposure to H2. Then again, monolayer MoS2 shows no hydrogen permeation under a pressure of 50 deg Celsius. So, the graphene-filled balloons theory is far from a complete failsafe.
The energy barrier for dissociation of molecular hydrogen on Graphene was calculated from the first principles. We used the generalized gradient approximation (GGA) and the projected augmented wave model. We chose a k-point mesh of 500 eV and a vacuum region to avoid frequent interactions. The energy convergence criteria were 0.01 eV/A.
As for the float time, a helium-filled graphene balloon will float for 8 hours or so, while a latex balloon will stay afloat for four to six hours in a hot environment. However, this period is significantly reduced if the balloon is left in the sun for a long time. Assuming it is kept in a relaxed environment, it should be safe and look good the next day.
