akshatrathi | 5 years ago | on: Primary energy vs final energy: why replacing fossil fuels may not be so hard

Totally right that what matters is greenhouse gases in the atmosphere. Tackling them, however, is going to take all our muscles. Many climate deniers have used the 80% of primary energy from fossil fuel figure as a way to claim it's too hard to do anything about the problem or to say there's been little progress. That's misleading and I wrote the article to explain to correct that narrative.

I wrote the story. The efficiency here isn't breaking the first law of thermodynamics. It's just the industry's way of measuring how much work gets done for a certain amount of input. If the work is heating or cooling, then shifting heat from in one direction or another can be done using heat pumps, which move three units of thermal energy for every unit of electrical energy consumed. Might that explain the conundrum?

They will be in the US, because there's supposed to be NHTSA-approved version. Given regulations in Europe, I assume that would be the case too.

That means this version has some more safety features than the the base model in China, which could explain why it costs more than 3x outside China.

I don't for certain. In my trip to China, I couldn't meet makers of LSEVs. What I do know is that there are no subsidies in that market, which means carmakers won't survive if they don't make a profit. But it's a good question whether they are making that profit at the cost of human lives (no crash protection) or the environment (lead-acid batteries).

akshatrathi | 7 years ago | on: Carbon Removal Technologies

I wrote a series on carbon capture technologies: https://qz.com/re/the-race-to-zero-emissions/

What I took away most was that carbon removal is now firmly a part of mitigating climate change. It's part of "Plan A" but also there is so much from the previous "Plan A" that will still need to work on. There are a number of carbon-capture technologies on current emissions that need to be deployed from power plants to cement factories.
