Nano-spike catalysts convert carbon dioxide directly into ethanol

[s0]

 

[Schoq]

is this rly something to get excited about though unless the energy required for the conversion is less than the energy released when burning the ethanol (physically impossible?(physics ppl help))

I think they're still researching this:

The researchers plan to refine their approach to improve the overall production rate and further study the catalyst’s properties and behavior.

But here's tiny bit of something to get exited about:

Given the technique’s reliance on low-cost materials and an ability to operate at room temperature in water, the researchers believe the approach could be scaled up for industrially relevant applications. For instance, the process could be used to store excess electricity generated from variable power sources such as wind and solar.

“A process like this would allow you to consume extra electricity when it’s available to make and store as ethanol,” Rondinone said. “This could help to balance a grid supplied by intermittent renewable sources.”

But how do we use ethanol? by burning it back?

Cash only
No credit cards. Drivers get paid directly with cash. BitCoin integration is on the way!

Thats the biggest bummer to me. I rarely have cash with me anymore. I will stick to cabify meanwhile.
