Question 1

What is a catalytic shift converter OR catalytic methanation associated with?

Answer 1

Gasification of coal

Question 2

What’s the estimated temp. @ earths core?

Answer 2

aprox. 5000 degrees C

Question 3

What’s the estimated geothermal gradient range per KM below earths surface?

Answer 3

15 - 75 degrees C per KM below the surface

Question 4

Where are Canada’s hot springs located?

Answer 4

the Southern Rocky Mountain Region (BC/Berta).

Question 5

Highlighted issue with solar and wind energy.

Answer 5

variability, intermittency, inconsistency

Question 6

Highlighted issues with hydroelectric energy (4).

Answer 6

1. Disruption of sediment transport/ free movement of native aquatic species
2. Destruction of shoreline ecosystems
3. Displacement of settled peoples
4. Seismic activity

Question 7

What’s the deal with hydroelectric dams (i.e., reservoirs) triggering seismic activity?

Answer 7

Water follows the path of least resistance, typically along fault lines/fault traces. Reservoirs for hydroelectric dams (especially during high water) exert a downward force on the underlying areas of instability (fault line/trace) which they overlie. This can increase the likelihood of seismic events to occurring within those areas.

Question 8

Flood tide vs. Ebb tide

Answer 8

Flood tide - movement of tide toward shore

Ebb tide - movement of tide away from shore

Question 9

Bay of Fundy tides can get up to ___m high.

Answer 9

16 m!

Question 10

Electrolysis

Answer 10

Separating hydrogen from water.

Question 11

Biggest problem to overcome across all renewable energy sources?

Answer 11

Energy storage

Question 12

Ideas for storing energy?

Answer 12

compressed air in underground caverns - Southwestern Ontario is well positioned for this solution b/c of teardrop shaped limestone/salt caverns.
