Takeaways:
- Sandia National Laboratories have used heated supercritical carbon dioxide instead of steam to generate electricity.
- This is a non-toxic, stable material that is under so much pressure that it behaves like both a liquid and a gas and is not released as a greenhouse gas.
- This year, the team managed to heat it up to 600 degrees Fahrenheit, generating 10 kilowatts of power.
