If you have a grape, a knife, and a microwave you don’t mind potentially ruining, you can make plasma at home. The process is simple: you cut a single grape nearly in half, leaving a bit of skin connecting the two halves, then microwave it by itself.

So, how do plasma weapons work? Strictly speaking they don’t, since no plasma weapons exist today. The electromagnetic confinement field would keep the plasma coherent on its trajectory, so that it’s still hot enough to cause damage when it arrives to the target.

No, it´s not possible. The main problem with energy weapons besides the energy source is energy efficiency: Energy converting systems such as lasers, ion or plasma guns never work at 100% efficiency. The rest of your collection even performs worse as they dissipate almost all of their energy on the way to target.

Blood plasma is yellow in colour because of the presence of a yellow pigment called bilubrin. This is usually not visible to us unless the blood cells are all removed from blood. The blood cells RBC give a red colour to normal blood. Plasma is made of water and proteins.

They make up just 2 in 50 people, their plasma is universal. This means their plasma can be used by anyone. At noncommercial donation sites, people can donate plasma every 28 days, up to 13 times a year. To learn more about donating blood, visit the American Red Cross .

The Red Cross urges people with type AB blood to consider a plasma donation. AB is the only universal plasma and can be given to patients of any blood type. This means that type AB plasma transfusions can be given immediately, without losing precious time determining if the patient’s blood type is compatible.

Group O recipients do not have either A or B antigen, so can safely receive plasma of any blood group type.

The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood.

Only about 3 percent of the U.S. population is AB+, making AB+ blood donors all the more valuable. Although people with AB+ blood can receive from any blood type, it is always preferred to receive blood from a person with the same blood type.

The amount you’re paid per donation depends on several factors, including how long the donation takes and your weight (the more you weigh the more plasma you can donate). Generally, you’ll see centers offering between $30 and $60 per session.

AB positive blood type is known as the “universal recipient” because AB positive patients can receive red blood cells from all blood types.
