Thank you for your thorough post. There are alternative models, such as biocyclic veganic agriculture, or in the future, foods created through fermentation [1] (this almost require…

Would be more than a plant based diet since there are more chains in between where plastic can accumulate (similar to heavy metals in fish)

There is a great mini documentary made that tries to answer this question https://m.youtube.com/watch?v=uD4izuDMUQA

I think you are underestimating the scale of our cattle. The majority of deforestation is due to cattle [1]. The world is basically dominated by us and our cattle [2] leading to ma…

I haven't dived into plant-based milks and health risks/benefits too much. What I can tell you is that Animal based Milk in general is not healthy, they are high in saturated fats,…

If plants suffer this is actually an argument FOR plant-based diets, since less plants/sentient beings suffer. Meat is a super in-efficient (land/water/energy consumption) way of t…

I synthetic fuels are a temporary solution for cars. If you are changing car infrastructure, IMO it makes most sense to switch over to electricity (highest efficiency and you can u…

I think you're making an incorrect comparison. This is basically an energy storage system. What you could do is compare the EROI of the energy source that provided it (say wind-ene…

There's a great profile on Australia’s complex climate politics and rising fossil fuel exports made by carbonbrief: https://www.carbonbrief.org/the-carbon-brief-profile-austral... …

This is a super interesting in depth article on the current state of climate policy, energy systems etc in Australia: https://www.carbonbrief.org/the-carbon-brief-profile-austral..…

An important point that people are missing is that by capturing carbon directly from the air with electricity we can combine two very important energy systems: electrical and chemi…

This is such a common misconception. US per capita emissions are around 15 tons and China is around 7 tons. And don't forget that there is a lot of creative accounting going on. Al…

Don't forget that there are also low temperature DAC routes that can use waste heat (climeworks, global thermostat, antecy, skytree). If you get the heat for free you only need ene…

Slightly off-topic: am I the only one noticing massive amounts of fake accounts that are into climate denying?

Check out carbon engineering[1]. They are using direct air capture and hydrogen to create synthetic fuels using a fischer-tropsch like process. https://www.carbonengineering.com/

There is a company in the netherlands that uses excessive heat with a similar idea to create air conditioning (SoundEnergy BV[1]). Unfortunately I can't really find a good English …

Afforestation is part of the solution but even if we would plant a lot of trees and not use them, this solution does not scale. Current most optimistic estimates think trees can se…

I've definetly come across charm industrial :). What is your plan on the negative emissions part? Underground CCS or do you have utilization plans?

I've read a lot of papers about negative emissions. My main take-away was: 1. It will be necessary 2. We can solve part of the problem with cheaper/easier solutions like trees and …

If you are interested in negative emissions this is the best review paper I've come across so far that covers all various negative emission technologies, from trees and oceans to b…

Modern heat pumps are still highly efficient at 40F (4C) the coefficient of performance is 4+ at this temperature. We switched from an hybrid set to a full-electric setup (also PV …

We ditched our gas and have an air to water heat pump, costed around €6000 ex subsidies (I live in Amsterdam so not the coldest weather, we also have solar thermal and PV). However…

Air to water heat pumps are also used in harser climates. If you're interested here is an example datasheet of an air to water heat pump (2018) (using Celsius here): PUHZ-SHW112YAA…

Direct Air Capture (capturing CO2 right from the air and utilising it in the form of synthetic fuels, building materials, polymers and more)
