We use fossil fuels precisely because they have
very high energy density — that is, they contain lots of heat energy in concentrated form; wind and solar do not.
(Do the physics on how much energy it takes to compress air to
a very high energy density, how much you lose in heating the air and how much of that heat is lost in the storage itself, how much you use when air rushes through a turbine like water, but unlike water running down hill whose speed / pressure stays the same, the compressed air loses force continually.
Bottom Line: Nuts have
a very high energy density and are easy to overeat on.
Wang said his research could yield the «holy grail» of magnets, having
very high energy density but made with common materials.

Packed with antioxidants that enhance your mood, health and
energy level There are several different «grades» of matcha green tea powder Which are determined by the quality of the appearance processing method and ingredients used: The color of the tea The texture, quality and
density The quality of the product The fineness of the powder How it was ground up Treatment prior to processing All these qualities help determine the grade of the Matcha green tea powder Which can be separated into two main categories: Ceremonial grade Culinary grade CEREMONIAL GRADE MATCHA GREEN TEA POWDER Sipped for centuries in the traditional Japanese tea ceremony Ceremonial grade matcha is the
highest quality green tea powder available This premium grade is vibrant green in color, with a
very delicate taste The leaves are stone - ground, makes the matcha suitable for a thick - style tea Thanks to its bright green color, it can easily be recognized from the other tea Often used for cooking and baking.
But because the
density of the gas in a fluorescent light tube is so low, even though the temperature is
high, the total amount of heat
energy is
very low.
As

energy directly into electric power
very efficiently and environmentally friendly.

energy source.
What also comes with it are
very high neutron flux levels, which open up a variety of applications for stockpile stewardship,
high energy density physics and nuclear physics.
A
high intake of greens, fibrous vegetables and low calorie fruits can help tip the
energy balance equation in your favor as fibrous veggies are
very low in calorie
density and some of the calories in the fiber are not metabolizable.
In addition to being
high in water, nutrients and fiber, they usually have
very low
energy density.
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.
On the left - hand end of the chart a
very high carb low fat diet can be hard to overeat because it has such a low
energy density and is so filling.
High fiber diets are charac - terized by a very low energy density compared to diets high in fat, and a greater volume must be consumed in order to reach a certain energy level (Duncan et al., 1983; Tremblay et al., 1991), which again could result in cessation of eat
High fiber diets are charac - terized by a

high in fat, and a greater volume must be consumed in order to reach a certain
energy level (Duncan et al., 1983; Tremblay et al., 1991), which again could result in cessation of eating.
The overall
energy density of this formulation may be a bit lower due to the lower fat content, but these dogs work in short,
very intense bursts, and consequently do not need consistently
high calorie intake.
I was trying to estimate the mining footprints of solar and nuclear, and came up with some
very tentative rough estimates that ore input for solar
energy might have an
energy density (per unit mass) ~ 5 to 80 times coal, while nuclear (convential US fuel cycle) may be ~ 20 times coal — on the solar side, this doesn't include some balance of system components, and on the nuclear side, it only includes the U, but on the solar side, the actual
energy density could get much
higher with recycling of the same material into multiple successive generations of solar
energy devices, and on the nuclear side, breeder reactors.
A huge laser delivers a large amount of
energy in a short time to heat the walls of the larger chamber, and the radiation emitted from those walls in turn drives the small capsule to a
very small size, increasing the
density of the gases inside to much
higher density than lead and heating it at the same time to
very high temperatures required for fusion to occur.
The reasons we use thermal plants for generating electricity is that these plants have a small footprint, can be located close to consumers, and produce electricity reliably at
very high energy -
densities.
Well, in my opinion, it means we need to treat our liquid fuels (with
high -
energy density) as
very precious resources as we have yet to prove that we can create a renewable liquid fuel even nearly equivalent to gasoline (petrol) or diesel.
