So, in that respect, you would have to say that yes, bananas
have more energy density compared to some other fruits.
Compared to a standard nickle - metal hydride battery, a super capacitor system
has more energy density and can charge and discharge much more quickly.
Not exact matches
However, the
more I researched the
more I realized that most of these types of foods tend to help milk supply in one of three ways: they contain phytoestrogens or some other hormone impacting component, they
have a high micronutrient
density (iron, calcium, potassium...), or they provide a good boost of
energy.
So we're interested in looking at a system that's far
more along the lines of the
energy density of the food, because we know that that
has the highest impact on...
Because water
has greater
density than air and flows are
more constant than wind, underwater turbines can deliver much
more energy than wind turbines.
To do this, Skyllas - Kazacos
has found an electrolyte that allows
more vanadium to dissolve, thus doubling the
energy storage
density.
By contrast, magnesium is much
more abundant than lithium,
has a higher melting point, forms smooth surfaces when recharging, and
has the potential to deliver
more than a five-fold increase in
energy density if an appropriate cathode can be identified.»
For decades, the memristor — short for memory resistor —
had been little
more than an engineer's dream: a circuit element with high -
density memory and low
energy requirements.
The new zinc - polyiodide redox flow battery, described in Nature Communications, uses an electrolyte that
has more than two times the
energy density of the next - best flow battery used to store renewable
energy and support the power grid.
The Department of
Energy's (DOE) National Nuclear Security Administration (NNSA) and Office of Science (SC)
have awarded
more than $ 14 million in research awards as part of the Joint Program in High
Energy Density Laboratory Plasmas (HEDLP).
Now, a team of researchers led by scientists at the U.S. Department of
Energy's Lawrence Berkeley National Laboratory (Berkeley Lab)
have reported that a new lithium - sulfur battery component allows a doubling in capacity compared to a conventional lithium - sulfur battery, even after
more than 100 charge cycles at high current
densities, which are key performance metrics for their adoption in electric vehicles (EVs) and in aviation.
But, for someone who hasn't seen you in two weeks, 3 - 5 pounds of weight loss,
more muscle
density, better posture, improved skin, and
more energy are EXTREMELY noticeable.
It coincidentally also
has an edge over slow work in improving bone
density and increasing metabolic activity (requiring
more energy expenditure).
It's hard to build muscle if you're not getting enough calories, and you
have to eat
more food to meet your body's calorie needs when you're eating plants due to their low
energy density.
Since the research
has repeatedly discovered that almost everyone will eat
more when served larger portions from a larger plate or container, and there is obviously a serious issue of «portion distortion» occurring, another group of scientists and psychologists decided to test this even further by providing larger plates or containers of low
energy density, high nutrient
density foods before the main course and or in between meals.
In other words, foods that are high in
energy density have more calories per bite than foods that are low in
energy density.
However, an example of a factor that affects the ability of your muscles to absorb oxygen
would be the extent of the blood capillary distribution at your muscles (
more blood capillaries means
more surface area for oxygen absorption), and an example of a factor that affects the ability of your muscles to use oxygen
would be the mitochondrial
density of your muscles (mitochondria are organelles in your cells that are primarily responsible for the cellular respiration process that uses oxygen to create ATP
energy).
Fruit and starch
have similar
energy density and so frugavore and starchavores don't need the huge small and large bowel, but they do need
more than carnivores which eat very high calorie
density food.
Alternatively, they don't adapt their approach as they progress (e.g. they don't transition to a
more nutrient - dense lower
energy density approach once their blood sugars
have stabilised on a lower carb diet).
The key drivers of
energy efficiency appear to be less about
density and
more about walkability... You can't
have walkability at suburban
densities, but you don't need to be New York or Hong Kong either.
It also
has high power
density, meaning that it produces
more energy per gallon than many other liquid fuels.
If low
energy density of solar is a problem in my home state of California, where we
have large deserts available for solar farms, imagine how much
more of a problem it is in South Korea, which
has far
more people per square kilometer.
(In case someone does not see why internal
energy is proportional to
density it is because if stuff
has energy, and you
have more of the same kind of energetic stuff, you must
have more energy.)
He concluded that as renewable
energy sources
have low
energy density,
more fossil - fuel such as natural gas should be burned for power generation, hence
more pollutants emitted.
They could be
had through regulations mandating
more urban
density, tougher home and vehicle efficiency standards, an increase in the renewable
energy mandate, transmission expansion, or almost anything else, really.
Compared with western Europe, the current leader in offshore wind
energy, the United States is estimated to
have more abundant and favorable onshore wind resources, which are largely located in areas with low population
density.
Given that Smil
has done
more than anyone to explain the relationship between
energy density and environmental impact, it's surprising that he spends so little time on this problem as it relates to renewables.
NYC
has some of the lowest per capita
energy consumption in the US due to it's
density which makes it far
more efficient.
