Two drinks and I have to get a taxi home.
As an energy source, the process of concentrating ethanol consumes a lot of energy. It depends on who you believe, but the amount of energy consumed may exceed the amount of energy in the ethanol created.
If that's so, then ethanol may be a useful form of energy (in the same was as electricity is), but not a useful source of energy.
Burning ethanol releases greenhouse gases.
One major drawback of hydrogen power is the cost associated with producing, storing, and transporting hydrogen. Additionally, the current infrastructure for hydrogen refueling stations is limited, making it less convenient for widespread adoption. There are also safety concerns related to the flammability of hydrogen gas.
Yes, ethanol is hygroscopic, meaning it has a tendency to absorb moisture from the air. This property can affect its use in various applications by impacting its stability, solubility, and ability to mix with other substances. In some cases, the hygroscopic nature of ethanol can be beneficial, such as in certain chemical reactions or as a solvent. However, it can also be a drawback in applications where moisture absorption is undesirable, such as in fuel blends or pharmaceutical formulations.
Not at all. Instead, they are being used in car engines as an alternative fuel as it is a green fuel (non - pollutant). But, the drawback is that you may have to change / modify the engine of your car to use this type of green fuel.
The use of fossil fuels is required to create pure hydrogen. APEX!
A major drawback of ethanol-based energy is its potential to contribute to deforestation and food insecurity due to competition with food crops for land use. Additionally, the production and transportation of ethanol can lead to increased greenhouse gas emissions, partially offsetting its environmental benefits.
Burning ethanol releases greenhouse gases.
A major drawback to medical therapy is the high recurrence rate of stones in those treated.
no
The Major drawback, is probably the gasses that will penetrate the Ozone Layer? My Name is amanda, and i am 13. I hope to be a Physicist when i grow up.
The major drawback is the political and social dissaprove because chemical weapons are bad for the environment and leave too much waste.
inaccuracy due to component drift.
False positives.
False positives
involves considerable overhead
One major drawback is the limited thrust that electric rocket engines can provide compared to chemical rockets, which can hinder their acceleration and overall performance in certain mission scenarios.
Mass distribution of such devices is costly.
