Enhanced geothermal systems: 10 Breakthrough Technologies 2024

Geothermal heat, an abundant and carbon-­free energy source, offers an alternative to fossil fuels that doesn’t vary with the weather or time of day. However, conventional geothermal plants require specific geological conditions—in particular, permeable rocks with water sources.

Because of this, geothermal accounts for less than 1% of global renewables capacity. But an emerging technology could let us exploit even more of the heat beneath our feet.

Enhanced geothermal systems allow companies to access geothermal heat in new locations, cracking open relatively solid rocks at depths much greater than existing geothermal wells. Water is then injected into these rocks to generate steam, which subsequently drives turbines to produce electricity. But the technology is not without potential risks. Read the full story.

The big story

The rise of the tech ethics congregation

August 2023

Just before Christmas 2022, a pastor preached a gospel of morals over money to several hundred members of his flock. But the leader in question was not an ordained minister, nor even a religious man.

Polgar is the founder of All Tech Is Human, a nonprofit organization devoted to promoting ethics and responsibility in tech. His congregation is undergoing dramatic growth in an age when the life of the spirit often struggles to compete with cold, hard, capitalism.

Its leaders believe there are large numbers of individuals in and around the technology world, often from marginalized backgrounds, who wish tech focused less on profits and more on being a force for ethics and justice. But attempts to stay above the fray can cause more problems than they solve. Read the full story.
