Around the world, the transportation sector is evolving. Globally, electric vehicle (EV) sales have more than doubled, showing a 72 percent increase in 2015, followed by 41 percent global increase in EV sales in 2016. Now, France is committing to a greener transportation sector by vowing to end the sale of gasoline and diesel vehicles by 2040, further pledging to become a carbon neutral country by 2050.

Currently, 95.2 percent of new car fleets in France are represented by gasoline and diesel vehicles. According to France’s Ecology Minister Nicolas Hulot, initiatives by automakers such as Volvo to go all electric in the coming years will help France start to phase out gasoline and diesel vehicles.

In order to become carbon neutral by 2050, France will also need to devote energy to ending the use of fossil fuels across the board, which includes ending hydrocarbon licenses in the country and stopping coal production by 2022.

While France’s goals are admirable, organizations such as Greenpeace believe that the measure falls short in terms of concrete measures.

“We are left wanting, on how these objectives will be achieved,” Greenpeace campaigner Cyrille Cormier said in a statement. “The goal to end the sale of gasoline and diesel vehicles by 2040 sends out a strong signal, but we would really like to know what are the first steps achieve this, and how to make this ambition something other than a disappointment.”

A few days ago we talked about fusion reactors and the new development out of the University of Washington that hopes to makes fusion a reality. Now we’re talking fusion again – only on a much different scale.

Lockheed Martin is making headlines for their announcement that their compact fusion reactors could be functional within one decade.

The company has been working for some time to develop a source of infinite energy, and have been devoting much time to fusion due to its clean and safe properties.

Their work on compact fusion revolves around the idea of using a high fraction of the magnetic field pressure, or all of its potential, to make devices much smaller than previous concepts. If they can achieve this, a reactor small enough to fit on a truck could provide enough power for a small city of up to 100,000 people.

Fusion energy appears to be the future of energy storage – or at least it should be. Fusion energy yields zero greenhouse gas emissions, no long-lived radioactive waste, and a nearly unlimited fuel supply.

Up until this point, there has been an economic roadblock in producing this type of energy. The designs that have been penciled out to create fusion power are too expensive and won’t feasibly outperform systems that use fossil fuels.

Now, the engineers at the University of Washington (UW) are hoping to change that. They have designed a concept for a fusion reactor, that when scaled up, would rival costs of fossil fuel plants with similar electrical outputs.

This from the University of Washington:

The design builds on existing technology and creates a magnetic field within a closed space to hold plasma in place long enough for fusion to occur, allowing the hot plasma to react and burn. The reactor itself would be largely self-sustaining, meaning it would continuously heat the plasma to maintain thermonuclear conditions. Heat generated from the reactor would heat up a coolant that is used to spin a turbine and generate electricity, similar to how a typical power reactor works.

Currently, the University of Washington’s concept is about one-tenth the size and power output of a final product, which would still be years away.
