Ask HN: Best location for a new Singapore-like city-state?

Taking into account:- Size: neither too big nor too small (Singapore is about 700 square kilometers).- Geographical position: climate (which will change), sea level (which will change, attention to coastlines), topography, soil quality (possibly).- The strategic position: trade routes, access to the sea (possibly).- Colonisibility: a piece of land that is disputed, under-exploited, purchasable,...

Ask HN: Would you be able to explain a trillion dollar GREEN company idea?

For example: recycling.Current recycling is far from optimal. A company could exploit this and raise recycling to a whole new standard.Its raw material costs would be zero or very low, its logistics costs would be high, but by using technology and automation it could definitely become (very) profitable.And to take on the task of retransforming, by extensive chemical engineering, all the...

Don't know exactly how it is calculated (in the example I gave).
It is $53B for 2017, recorded in December 2017.
Anyone ?

Ask HN: What volume (in dollars) of materials is discarded/burned every year?

Here :https://www.telegraph.co.uk/science/2017/12/13/discarded-phones-computers-electronics-behind-worlds-fastest/53 billion dollars in December 2017 for discarded phones/laptops/electronic devices only.But what about EVERYTHING ELSE that's thrown away or burned? Tires, cars, paper, furniture... How much do you think that amounts to?

Re:Ask HN: How to disrupt the payment card industry? on Wednesday February 12, 2020 @03:59AM (#22307141)
Very difficult, because those companies are literally taking no fees, most of the fee is actually cashed in by the banks when they decide to approve a transaction. To compete with Visa and Mastercard you need to be the bank, lower the fees, and propose the same level of transaction performance. And that's a challenge.

There is some space in the cross-country payment market though, and some (a lot, actually) in the B2B payment market too.

Ask HN: Should we merge all SaaS?

I am currently working in a startup.It is very difficult to navigate between the tools, which often have features in common. With 5, 10 and up to 20 different tools, how are we supposed to organize ourselves, train ourselves in use, manage our accounts, etc.?And how is a company supposed to be able to manage all these subscriptions financially?How do I know what tools to keep? Which ones to...

What could we be able to manufacture in space in the next 15/20 years in your opinion?

How about a logistics company ?

It's actually one of the best solutions proposed here.

Thanks, very interesting. Could you develop steps 2 and 4?

In short, infrastructure. Where would you start?

By "bootstrap" I mean a way of self-financing part of the activities, finding a source of income quickly rather than relying solely on fundraising.

Raising money is not a problem, but I don't see myself getting involved in creating a business that requires billions and billions of dollars in financing before generating a single cent.

For what purpose?

Telecommunications?

Ask HN: Will Fintechs Die?

Or be absorbed by big techs ?As we can see, large tech companies are turning into finance. Amazon has launched a full range of services. Google is on the same path. Uber began to manage the cash flows on its network itself.It seems that big techs, which control consumers (and have become the operating systems of our lives) will end up managing everything themselves rather than relying on...

Only 10/15% ? On what level of net income ?
Yes, I started that "trillionaire" thread too.
I'm betting on Education too. Healthcare seems just as big and inefficient to me honestly.
Seems relevant. Maybe some kind of global financial technology company such as Ant Financial.
What about Healthcare ? Massive and still highly inefficient industry here.
He is certainly well positioned, but Amazon is already 23 years old, industrial cycles tend to shorten and he himself anticipated the death of his own company.
