3. What is alternative energy
Alterative energy is an energy source that could
replace the normal form of energy production.
Alterative energy Is Usually Green and produces non
or little environmental impact. Although alterative
energy Not used that much because most of the
time it is less efficient then the current ways of
getting energy like fossil fuels.
4. Why is it my passion
Futuristic energy is my passion because a have always
being astonished by it. And I what to learn more about
it . And maybe when I am older help solve the world
energy problem and find an alterative to fossil fuels.
Lastly I Am passionate about science and this is a very
scientific
5. Why do we need Alterative
energy
Right now we get most of our energy from fossil fuels
which is ok but the will eventually run out. Burning them
causes huge amounts of co2 and sulfur die oxide into the
atmosphere. Which will gradually destroy the ozone.
Layer. Are only hope is new means to generate energy
6. What will happen if we keep
using fossil fuels
If we keep using fossil fuels many horrible things will
happen. Firstly If we use up all our fossil fuels which
will happen in 70 years. If we uses it the way we do
now. Tis would cause a huge wave of power lose
that would then lead to the destruction of all
humanity. Lastly there might be so much co2 and
sulfur in the atmosphere that all animals including
homes have perished
7. Alterative energy now
right now we have many alterative energy sources
besides fossil fuels like wind hydro, and tidal power
but we do not use these types frequently because
the all have huge cons and a low energy output
compared to fossil fuels
8. Safe fossil fuel burning
Burning fossils on earth is not safe for the environment
but burning fossil fuels on other planets especially
ones that are not capable of sustaining life might be
an option. The only problem is you need oxygen to
burn fossil fuels and if we did find a planet with
oxygen, we would be more interested in living there
then burning fossil fuel there
Or we could rocket
harmful gasses to space
at huge expense
9. Safe fossil fuel burning 2
New technology can allow fossil fuels to be burnt
without emitting tons of co2 and sulfur. These new
methods uses special filters to capture harmful
gasses. The harmful gases can then be disposed of
or sold to people who have use for them. Finally the
co2 can be put back into the ground and help new
fossil fuels develop
10. Burning garbage for energy
Most garbage waste can be burnt for power
creating a winwin situation creating energy and
reducing waste. The only problem is that burning
most garbage especially plastic releases many
harmful chemicals into the air. Luckily these harmful
chemicals do have some safe uses and can be
filtered from the smoke
11. Next gen wind turbines
Lets face it standard wind turbines are not very effective
- They take up lots of space
- You need lots to be effective
- There expensive
- They have a low power output
- They interfere with radar
- They need to constantly rotate their terbines to face the wind
- For those paranoid people, they do hit a couple of birds
New thing like of shore
wind farms have come
out but a better design is
needed
12. Next gen wind turbines
This new wind
turbine Is
suspended
high in the sky
because wind
is stronger
there plus it’s
a cheaper
then mounting
a turbine on a
tower
13. Next gen wind turbines
This wind
turbine can be
driven by wind
from all angles.
Removing the
need to angle
the turbine
blades. And it
does not need
to be mounted
on a super tall
tower
14. Next gen wind turbines
This wind
turbine has a
circular disk
around it for
better
efficiency. The
disk forces
more air into
the blades
and the disks
reduce wing
tip vortexes
and drag.
15. Algae biofuel
Oils in algae the bacteria like micro organism plant. can
be used as gas in most vehicles today without alterations.
Algae unlike most biofuel plants requires little car and
grows like a weed. Finally the exes algae from the oil
extraction can be used as high grade fish food for farmers.
Finally algae absorbs huge amounts of co2 from fossil fuels
burned in the past and reuses them again, and absorbs
more co2 then most plants and it is cheap to grow, as all
you need is water and co2 and a tiny bit of food Although
Algae does eat other dead algae cells for food.
17. Hydrogen fusion
Hydrogen fusion is the process that goes on inside a
star that creates energy in the form of heat and
light. This process is similar to the process nuclear
power plants use. But with some changes. Firstly
hydrogen fission creates helium as a by product
instead of toxic waste which is a by product of
uranium. And secondly it creates huge amounts of
light which can be transferred to electricity via solar
panels. And thirdly its very easy to turn heat to
electricity. Finally its self sustaining and can run for
years without new fuel
18. helium
The two hydrogen atoms
combine under the huge
gravitational pressure creating
helium
The process
gravity
h
19. Energy transferring
The heat from the fission can then be transfer to
electricity via steam turbines or using the Pelteir
cooler. Although the amount of energy generated
might be to much for our energy transfer systems to
take. Scientists are also looking for more complex
ways to transfer energy so less energy is transferred
into unwanted stuff and all the energy goes to the
purpose it is used for.
20. The problem
Hydrogen fission is almost impossible to pull off with the
tech we have today. And if we could pull it of it would by
too dangerous. And finally gravity is the only way to create
hydrogen fission that we no of and again there is no way
we can control gravy to reliably and safely create a star.
The amount of light and heat put out by a sun would be to
much for modern tech to handle at short distances. And
finally if a hydrogen fusion reactor wear to run out of
hydrogen it might explode with the force of a nuclear
bomb.
If a grain of sand in Italy was heated
to the temp of the suns core it would
fry every person in Europe. And in a
month the heat would make earth
too hot for humans to live
21. fuel cells
A fuel cell is like a battery but it has huge differences.
Firstly it needs a constant flow of fuel. And secondly
its used fuel can be reused again and again with the
proper machinery. And thirdly they uses no harmful
acids like batters do and they are lighter
h
ox
22. Also hydrogen can
be collected from
the atmosphere and
oxygen can be
found anywhere
Firstly to make the fuel
Firstly to make the fuel And electric current is run
through water with and electrolyte like salt added to
it to split water molecules into separate atoms.
Storage tank
battery
23. What is happening
The electricity causes the water molecule to break
up by increasing the number of electrons the
molecule has until there is an amount capable to
break the molecule apart. During the process the
oxygen atom and two hydrogen atoms turn into a
gas and leave the rest of the water as the form of
hydrogen and oxygen gas into a storage tank with
no impurities reed for use
o
25. WHAT are these USED FOR
Fuel cells have mostly been used in electric cars to
replace their batteries. The reason that fuel cells are
going to replace batteries is that they have many
benefits. They take up less space and are lighter
then batteries. Their fuel can be more easily reused.
And they don’t use any harmful acids like batteries
use. Fuel cells use very common elements like
oxygen and carbon making them practical plus the
by product is clean h2o plus this by product can be
reused. More uses for these fuel cells will come out in
the future but now fuel cell will be used mostly just for
cars
26. Pelteir cooler
Inside this
device there
are negatively
charged metal
cells that can
remove heat
from air and
generate
electricity
The peltire cooler was designed as a unmechanical cooler in complex machinery
where vibrations of mechanical coolers with
fans could damage something. This cooler
takes in hot air and emits cold air from the other
side. This device has an useful by-product of
generating electricity

blade by varying air pressures on the top and bottom of a
wing. This vortex creates turbulence and high amounts of
drag
IONS: is an element or molecule that is willing to ether give
its electrons to other atoms or take electrons from atoms.
Or is an element that is not stable with an equal amount of
protons and electrons.
Fusion: a process of adding protons to and element to
make an unstable element and a whole lot of energy.
29. Self refection
On this p3 I tried to show of all the skills learnt in term one grade 7
combined with previous knowledge to make this project the best
it could possibly be. During the project I worked hard in class
overcoming distractions and many school nights making sure That
this project was something I was proud of. I used many sights to
find info on my topic and I used so many that I could not keep
track of all the sits I used and had to exclude some from the
bibliography. I tried to make this slide show as info packed as
possible and I put in many cool animations to better express my
project. The pictures were also chosen to be understandable and
helped clearly show the ideas that I was projecting. One thing
that I could have worked on is descriptive writing to better depict
in words what I am saying. There were a few things in my project
that I could of made better if I had a bit more time but these
tweaks would have only made a small impact on my
presentation. Overall I am proud of my efforts on this project and
will present on Monday with no hesitation as I did memorize what I
have to say. This project has actually been fun and I look forward
to the second one coming up in a few weeks.
