Throughout my research I have come learn that innovation is never
ending. It might seem to the masses that not much is being done, but if you
look past the surface a little bit you will see a different picture. Scientists
and engineers are progressing with their designs in renewable resources.
Strategies are being implemented to lighten our dependency on fossil fuels. Hydrogen
and solar energy seem to be the front runners as the energy source to replace
fuel, but that too can change. Other sources can potentially get that jump as
new technology is discovered. Perhaps we may come across an unknown element
with far more benefits. Fossil fuels will be a thing in the past and how will
some countries take it? As I have mentioned before, economy plays a big role in
all this planning and progression. There are some countries who rely heavily on
its exportation income. Countries in the Middle East are an example of this.
Will these countries fall when we do make the switch, or will they adapt and
overcome? Will we be able to avoid any sort of tensions? With big strides being
taken much planning must be implemented once we find this source of energy that
can replace fossil fuels. Costs could also go down in certain systems that are
currently considered expensive. Perhaps asteroid mining will do just that. Once
we have vast access to materials we need anything is possible. This is no
longer of if we will find that source of energy we need but when. I’m looking forward to seeing what sort of
changes we will see in the future and what sort of possibilities these changes
will bring. I truly hope that for the first time in centuries we can truly say
we are independent of fossil fuels.
If we truly wish to rid ourselves from fossil fuels, we need
an energy source that is both renewable and efficient. Finding that energy
source will not only provide us with our energy needs but relieve us of any worry of
this resource ever running out. As I did some research I found that solar
energy took a huge step in efficiency. Weforum.org published an article written by writer and journalist Tom Ward which talks about "the solar panel of the future". Ward states that scientists were able to successfully develop a solar panel with a record energy efficiency of 44.5%. Typical solar panels that you see in house rooftops produce 25% as Ward put it. This feat is made possible by stacking multiple solar materials together in one panel and catching more wave lengths of sun rays. Energy efficiency is
calculated by dividing 3600 to the plant’s measured heat rate. According to
Enggcyclopedia.com a typical coal powerplant produces between 35-38% energy efficiency. The
problem I see here is their efficiency when there is little to no sunlight. Would these panels be better suited in orbit? Not only will these panels be getting plenty of
sunlight but there is also less obstructions like clouds. With that in mind we’d
have to think about the initial costs to get these panels up in orbit. The cost to sending anything up into space is quite a lot. Perhaps
in time other renewable resources such as wind and water could gain an
efficient system as well making them another contender to replace fossil fuel.
Hydrogen would be the resource to benefit most from these innovations. Hydrogen fusion reactors seem to be the answer to the future but are still under the developmental stages. These fusion reactors basically mimic the sun which takes in hydrogen and converts it into helium which then outputs a tremendous amount of energy. This will not only give us a limitless supply of energy since hydrogen is the most abundant element in the universe but also produces no greenhouse gasses which has no negative effects on the planet. I found an article from the library database published by The Chemical Engineer (TCE) in which MIT engineers predict fusion reactors to be reality in 15 years. With $32 million of funding being provided from ENI, the collaboration of MIT engineers and CFS will strive to make efficient semiconducting electromagnets. These efficient magnets will provide for a more compact and functional system when compared to other reactor designs. This system will be more commercially practical and possibly less expensive. Development of these magnets are expected to be completed in three years. Will its efficiency be enough to power a city effectively and affordably in the predicted time? With so much progress perhaps every community will be powered by a miniature sun.
Both sources provide some positive insight with their respective energy source topic. Both sources state that progress is being made as new materials and designs are developed. Although costs tends to be a common problem with these two renewable sources of energy. Ward has claimed in his article on solar panels that the materials needed are quite expensive and that perhaps in time affordability will be possible with further enhancements. In the TCE article it is noted that $32 million is provided to fund this fusion reactor project and I'm sure other projects of this sort have gotten into the billions. Ward made it a clear point to his audience that initial spending is necessary and that it was going to be expensive. TCE only mentioned the funding amount going to the project. It was failed to mention how this system can be a financial burden even after its completion. I feel economy plays a key role in energy. Would consumers buy into this solar energy or hydrogen fusion reactor projects if the return investment isn't so certain? If energy isn't affordable people will be quick to turn away. Just like when gas prices rise up and drivers look for alternative fuels, consumers will always stick to the more economic route. We must keep that in mind and perhaps when new designs and ideas are implemented we can all take the full plunge and rid ourselves of our dependance in fossil fuels.
