expand and with our world facing immense
[12]
challenges from housing to

transportation and our use of natural

resources
[17]
supersized construction projects have
[19]
begun to proliferate
[20]
[Music]
[27]
with eye-watering budgets extreme

complexity staggering scale and
[32]
far-reaching impacts

the 8.5 billion us dollar upgrade to

chicago's o'hare international will mark
[72]
the first comprehensive redevelopment
[74]
and expansion of the terminal core in
[76]
the airport's history
[78]
the master plan will see terminal 5
[80]
expanded while terminal 2 will be
[83]
completely rebuilt becoming a global
[86]
transfer hub with two satellite
[88]
concourses
[89]
adding 280 000 square meters of space
[92]
and 50 additional gates to the airport
[96]
to minimize disruption the new
[98]
concourses will be built first allowing
[100]
them to take over operations from
[102]
terminal 2 when the existing building is
[104]
demolished
[106]
work on terminal 5 is scheduled to
[108]
complete by 2022 and subsequent phases

a joint project between 35 nations the
[124]
iter formerly known as the international
[127]
thermonuclear experimental reactor is
[130]
currently under construction in france
[132]
once completed the 20 billion us dollar
[135]
center will allow scientists to recreate
[138]
the fusion reactions that take place
[139]
inside the sun potentially
[141]
revolutionizing energy production
[144]
consisting of three main buildings the
[147]
product is centered around the tokamak a
[149]
magnetic chamber that will contain the
[151]
plasma created when particles are heated
[153]
over 150 million degrees celsius and
[157]
collided to produce fusion energy
[160]
construction of the vast building that
[162]
houses the reactor began in 2013
[165]
requiring the development of 10
[167]
different types of concrete to shield
[170]
workers from radiation
[172]
with more than 60 percent of the reactor
[174]
complex already complete work is now
[176]
underway on the tokamak inside its 337
[180]
000 tonne housing chamber
[182]
the entire complex is due to come online

ethiopia's grand renaissance dam sits
[196]
alongside nigeria's echo atlantic and
[199]
egypt's 58 billion new capital as one of
[202]
africa's most impressive mega projects
[205]
with work first starting back in 2011
[208]
the dam will become the continent's
[210]
largest hydroelectric plant
[212]
generating some 6.45 gigawatts of power
[215]
when it completes in 2022
[218]
standing 155
[220]
meters tall and extending almost 1 800
[224]
meters across the blue nile the main
[226]
structure is being formed with over 10
[228]
million tons of concrete holding back 74
[232]
cubic kilometers of water when the
[234]
reservoir is full
[236]
while the dam will transform ethiopia's
[238]
energy production the project has been
[241]
marred in controversy since inception
[244]
20 000 people were relocated to enable
[247]
the construction works and many have
[249]
raised concerns over the project's 4.8
[251]
billion us dollar price tag which
[253]
represents roughly six percent of
[255]
ethiopia's entire gdp
[258]
and saw funding diverted away from other
[260]
much-needed energy projects
[263]
the dam has also reignited an ongoing
[265]
dispute between ethiopia and the
[267]
downstream nations of sudan and egypt
[270]
who see the project as an attempt by the
[272]
ethiopian government to gain regional
[274]
influence

the two cities within 40 minutes of each
[318]
other
[320]
set to become one of the shortest routes
[322]
on the shinkansen network
[324]
90 of the trackway will run underground
[327]
and beneath the japanese alps reducing
[329]
the travel distance by over 50
[331]
kilometers and saving 4.9 billion us
[334]
dollars over alternative options
[337]
the new line set to open in 2027 plans
