Chapter 175 Hot air balloon tour
The principle of a hot-air balloon was very sih a few difficulties, the first part was the burning device, and the second was the airbag
The first point, in the absence of pressure vessels that could provide gas fuel, he had to rely on firewood or charcoal to heat the air However, the efficiency of this was too low and he had to come to accept that he wouldn’t be able to fly with it very far with it
This also meant that the principle of hot air balloon travel had been discovered inal world, but nevertheless, there was a reason why they had only been able to use it in real co Roland however, could abandon the burning device altogether, and instead let Anna take over for the heating
The second proble this issue, it was so that Roland could at least use the experience of his predecessors for, and easily solve the proble a sandwiched fabric The outer layer of the balloon was made out of a wear-resistant canvas, the center layer was made out of the intestinal epitheliuauze With this, he was able to prevent leakage, while it alsopecked at by birds
Roland propped up the opening at the botto Anna to raise the inside temperature with the help of her coly to be like ainto account that the hot air balloon would have to carry two people, the maximum diameter of the balloon needed to be at least at fiveup the intestinal epitheliu lasted almost for a whole week If it wasn’t for the fact that he was the Lord of the town, it would never have been possible for hi the buoyancy provided from hot air?” Anna asked “I remember that hot air will always rise up
“Yes, hot air rises, while cold air sinks, this is a co the particle theory to explain it, due to the air being hot, the particle’sits diffusion into the surrounding, and with the expansion of the volume, its density will beco air doesn’t change, the air in the balloon beco it to rise
When Roland finished explaining the principle, he discovered that with the exception of Anna who showed a “so that’s the reason” expression, the other three witches were at a loss, seeing this he couldn’t stop hi about the importance of innate talent
When the balloon was cohtened the draglines Roland took the lead and entered the basket first Afterward, he helped Anna to clihtingale, “maybe it would be better if you letwill happen,” Roland s unexpected, there is still Lightning”
“You can rest assured, I will catch the patted her chest confidently
“There’s also ’s appearance
With a shake, the balloon’s basket took off fro, they had crossed the top of the castle, and the whole town started to spread out in front of the new, after all, he had looked out of a skyscraper But in Anna’s view, it was a new experience, it was a perspective that she had never seen before She leaned over the edge of the gondola and looked out of it, grabbing at Roland’s ar totally excited while also being nervous at the same ti such an expression, it’s probably because her two feet have never been far away off of the ground before So, flying in the sky for the first tiht fear of heights
Soon, the basket which was tied to a he its rise The he, in other words, it was around the height of a fifteen to sixteen-story building Roland let Anna reduce the fire so that the hot air balloon could begin to hover within the air
Lightning who had stayed close the basket for the whole ti in the air she felt assured and thus she started a gaie around the hot air balloon
When looking down froht they could clearly see the castle roof, the constructions taking place all across town, the Redwater River flowing froreen farmland on the other side of the river
“How do you feel?” Roland asked with a sift,” she said excitedly “It turns out that even I could fly so high”
“You can even fly higher,” Roland sat down next to the side-wall of the rattan basket “If the following heher, but up there the airflow is much more chaotic, and it would become harder for us to still stay safe Furthermore, this is only the first aircraft, just wait until I invent a piston her than even the birds, and then…” He looked up at the blue sky full of hope in his heart, “humanity will one day fly out of this world and into the boundless space”
“…” Anna held her breath, her eyes were shining and full of expectation for as to couarantee that ill be able to fly out of the world,” Roland beca a piston machine, so that even ordinary people can fly around like the birds, the rest of h time to achieve that”
