Q

Describe the technological life cycle

A

Early market- early adopters of tech, visionaries, begins to become more mainstream as more people accept it and use it (and price decreases), decreases when new technology is introduced

Q

Why do patents cause concern for poorer countries?

A

Cheaper copies of drugs and tech cannot be made, so access to possibly life-saving tech not possible, funds are returned to developed countries (e.g. USA accounts for 40% of all tech patents)

Q

How does the level of economic development create inequality of access to technology?

A

MEDCs and TNCs invest more into R&D, protect innovations, restrict access in LEDCs through patents, MEDCs have funds to invest into infrastructure to support technology e.g. HIV drugs limited in LEDCs due to patents, Brazil started to make cheaper but illegal copies of some technologies

104
Q

What is the difference between Thomas Malthus and Esther Boserup in their relative theories?

A

Benefit- could take as little as 5 years to reduce temperatures to pre-1900 levels

Costs- $100 million a year, need to release sulphur monthly, could never stop without immediate and sustained global temp. rises, risk of acid rain, reduce global rainfall, regional climate change

110
Q

How would the idea of mirrors in space work to reduce climate change?

A

16 trillion metre-wide flat fisks launched into space by 20 million rockets to reflect solar energy away

111
Q

What are the 2 benefits and 4 costs to mirrors in space?

A

Benefits- received NASA funding, would reflect solar energy effectively

Costs- would reflect solar energy (possibly too much), $4 trillion over 30 years, not a quick solution, questions of power for rockets and materials

112
Q

How could artificial trees with the new carbon dioxide scrubber prototype work to reduce climate change?

A

Ion-exchange membrane on trees extracts carbon dioxide from air, then used to intensify plant growth in greenhouses

113
Q

What are the 3 costs and 3 benefits to the artificial tree idea?

A

Costs- prototype cost $100,000 and takes 2 years, question over appearance, NIMBYism

Benefits- single tree could remove 90,000 tonnes of carbon dioxide a year, benefits plant growth, easier than capturing vehicle emissions directly
