By 2050, electric vehicles are expected to be the primary type of vehicle. What will cause this change?
We have already passed peak oil predicted by Hubbert.
Oil will be plentiful but people will realize it causes emissions that contribute to global warming
Charging stations sponsored by the government
Electric vehicles are cheaper to produce than gas powered cars.
What is the main reason why hydrogen is more difficult to store than diesel?
Hydrogen is a gas at room temperature but diesel is a liquid
Hydrogen can be liquefied by cooling it
Hydrogen can be stored under pressure
What is a strength of using hydrogen-oxygen fuel cells in manned spacecraft, compared to using chemical cells?

Quantumscape (QS) has been in the news recently for profession that they have made the first solid state lithium ion battery. Their stock made a huge jump because this would be a money maker in the auto industry. This is because Li-ion batteries...
would allow cars to travel further on a single charge
would allow cars to be built without batteries
weigh less than other batteries
are cheaper
Where is Geothermal energy most used?
Iceland
Greenland
Sweden
Denmark
How do geothermal power stations work
Cold water is heated up and the water power turbines under the water and turns it into electricity!
Cold water is pumped down and the cold water meets the hot water from inside the earth to produce steam to power turbines then creating electricity !
The hot water from inside the earth meets cold air and produces condensation which powers the turbines and turns it into electricity!
