Re: Request for Startups: Climate Tech

a few ideas, in no particular order - stop burning fossil fuels to the altar of the crypto crazy - stop burning enormous amounts of fossil fuel to produce AI models that poorly replicate human skills, without asking if someone wanted it - support power efficient devices or appliances. I despise Apple, for a lot of reasons, but the M series is a big step in the right direction. - don't buy Teslas, buy small cars that…

- don't buy a new car ever again, just fix your old one.

good one!

there's a bit of regulatory problems in Europe[1] about that, cars need to adhere to certain emission standards to circulate in large areas of big cities, but definitely fix before buying is the old way that becomes new again.

In this light the right to repair is very important.

I'd say that the solutions should start from the top first. 100 companies are responsible for 71% of global GHG emissions.[1] That's a mind-boggling statistic. The counterargument is, of course, that these companies are supplying the demand; that consumers should vote with their wallets, change their habits, recycle, reduce their "carbon footprint", etc. This is the usual deflection propaganda pushed by the companies…

>100 companies are responsible for 71% of global GHG emissions. I've always found that stat to be misleading, as it uses the word "responsible" in a very unconventional way: essentially, GHG emissions come from fossil fuels extracted by these companies, even though the companies themselves aren't the ones using the fossil fuels nor producing the GHGs. This upstream analysis just doesn't seem very useful to me. You me…

> I've always found that stat to be misleading, as it uses the word "responsible" in a very unconventional way

I used that word, while the original article[1] and report[2] use "linked to". Maybe you'll find that less misleading.

> GHG emissions come from fossil fuels extracted by these companies, even though the companies themselves aren't the ones using the fossil fuels nor producing the GHGs.

That's addressed in the report. Usage of their products makes up the majority of emissions, but it's not true that companies don't use the fuels or emit GHGs.

> Scope 3 emissions account for 90% of total company emissions and result from the downstream combustion of coal, oil, and gas for energy purposes.

Direct operational emissions (scope 1) are also taken into account. These "are attributed to the extraction and production of oil, gas, and coal."

> I fail to see how China Coal (top 1), Saudi Aramco (2nd), or Gazprom (3rd) could do anything about their process to significantly reduce the amount of emmisions from their products.

Oh, they can do plenty. From reducing their own operational emissions and optimizing the refinement of their products, to diversifying their business strategies to avoid these emissions in the first place. How about investing their vast resources into driving climate technology forward? These companies should be the first to invest in new technology, instead of startups having to claw their way into the market.

How about we stop the growth of coal production in developing countries? If China alone would avoid making the same mistakes the West did, it would have a huge impact.

But you're conveniently building a strawman that addresses only fossil fuel producing companies. Let's ignore these and focus on other industries. Are there no changes these companies can do to significantly reduce their emissions? I doubt that very much. Changing how these companies operate would have a far greater positive effect than what any tech startup, or group of individuals, can do.

> Other solutions from climate tech like better electricity production and storage needs to happen simultaneously, not after by "getting our priorities straight".

I never said that other solutions don't need to happen simultaneously. But it's clear that the brunt of the responsibility is on corporations and governments.

Almost all climate tech is greenwashing; superficial solutions. Climate issues require deeper system changes. We need a system which encourages financial prudence and frugality instead of one which encourages financial recklessness, infinite growth, consumerism and bullshit jobs. The problem needs to be solved at the lowest monetary incentive layer. How much energy is wasted by people travelling to and from their bul…

Be that as it may, I think this initiative by YC is mainly because they noticed a lot of talented founders were starting Climate Tech companies. pg had a tweet about this a while ago.

Are you suggesting there is a solution without innovation, or that there is no solution at all?

Public policy >> tech solutions. You might get a few people to replace their water heaters if you come up with one more efficient, but that's nothing compared to federally funded nuclear plants.

You can't heat your home with public policy

You can if you print them out first.

A tesla weighs 2-3 times more than a compact car, so that means it must be extremely efficient pound for pound. Nevertheless, I doubt many people, until recently, bought Tesla's because of (ostensible) environmental concerns.

How does your efficiency argument follow from merely weight?

If you can move a heavy object using less energy than others move a much lighter object, then it would seem that you are quite efficient. Unless we're talking about constant speed in a vacuum.

Yes, but where does the less energy argument or data come from?

There are some cars coming out next year that are more energy efficient than a Tesla, like the Hyundai Ioniq 6, but I don't know of any currently widely available vehicles that are.

Every single Tesla owner I know bought it for environmental reasons.

I'm not convinced that the solutions to climate change are tech related. If anything, climate change is tech driven. Addressing climate change doesn't really require startups and venture capitalist pump and dump schemes. It requires social and behavioral changes, mainly centered around consumption. Basically everything on this list would increase consumption, manufacturing, construction, road building, etc. There are…

> If anything, climate change is tech driven.

It's sad to see such comments systematically downvoted on HN. I understand most people on here (including me) are paid to believe otherwise but you should really look at the history of tech and energy for the past 200 years or so, and also listen to competent people (i.e. not Musk nor PG) about the energy and geological resources challenges we're facing. Even if you don't care about climate change at all.

It is demonstrated in the lab and we are developing a way to assay what’s going on in the open air. Lot of interesting work in this area.

Do you have papers/whitepapers you can share (privately or otherwise)? (I run a climate engineering group to help accelerate mitigation/removal methods.)

Click on the menu item at the top of the page marked “Science”. All the rest is for the lay audience.

Can you say more about your group?
