Topic: Chapter 3 – Implications of wider issues
New and Emerging Technologies examples:

Artificial Intelligence :

- Considered a threat in how it may create mass unemployment
- Involved in many aspects of our life - keep inboxes free of spam, help web transactions, fly planes, drive cars
- Work continues to develop safe, sustainable, independent robots

Biometrics:

- Passports: automated passport checks
- Phones, fingerprint scanners, face ID
- Recording arrival and departure times at work places

Virtual Reality:

- Used for training purposes
- Expensive
- Allows for realistic simulations, providing training otherwise impossible
- e.g flight simulations for pilots, racing simulations for racing drivers

Drones:

- Used in numerous industries, from retail to manufacturing
- Have potential to carry out courier roles, resulting in unemployment
- Threat to human jobs

Energy:
How energy is stored:

- Kinetic energy
- Thermal energy
- Chemical energy

Non-renewable sources of energy:

- Come from finite sources like coal, crude oil, natural gas (which are called fossil fuels)
- Creates carbon-rich chemical energy sources over lots of time
- Burnt in power stations so generate thermal energy, which is used to move turbines and generate electrical
energy
- Another way to do this is by generating heat through nuclear fission

Renewable sources of energy:

- Hydroelectric power: Dam traps water which turns turbines to generate electricity
- Wind: Blades catch wind to turn turbines
- Solar: Photovoltaic cells convert light to electricity
- Tidal barrages: Turbines turn as tides enter
- Wave: Motion of waves forces air up cylinder to turn turbines
- Geothermal: Cold water is pumped underground through heated rocks, the steam turns turbines
