New alternative to Trump's wall would create jobs, renewable energy, and increase border security

A consortium of scientists and engineers have proposed that the U.S. and Mexico build a series of guarded solar, wind, natural gas and desalination facilities along the entirety of the border.

  • The proposal was recently presented to several U.S. members of Congress.
  • The plan still calls for border security, considering all of the facilities along the border would be guarded and connected by physical barriers.
  • It's undoubtedly an expensive and complicated proposal, but the team argues that border regions are ideal spots for wind and solar energy, and that they could use the jobs and fresh water the energy park would create.

  • Solar geoengineering aims to cool global temperatures by reflecting some of the sun's light back into space.
  • The team plans to test how releasing particles at high altitudes affects a small part of the stratosphere.
  • Solar geoengineering solutions such as this could be a relatively cheap way to curb global warming.

New air-conditioning design cools without using fossil fuels

Is the future with radiative cooling?

Linda Cicero, Stanford News
  • Scientists at Stanford have developed what is essentially a fossil-free air conditioner.
  • It absorbs solar energy, creates a heat sink, and releases that heat through radiative cooling.
  • The device is still in development.
