The main difference between male and female is cost of reproduction. Sperm is tiny and can be produced in massive quantities. Eggs are much larger and take more energy to produce. This difference is then carried into other parts of repro

In my company managers were just given a free pass on difficulty with WFH managment. It was never treated as a "performance issue" by the corporate system. People are still measured the the world that existed 10 years ago. Wha

The distinction is that wind/solar arrive for free without any effort. That just isn't true of nuclear fuel. I don't think that is a problem particularly. More that "renewable" is the wrong word.

I watched my nephew create a training montage for a toy. He takes in some video sequences, adds some music and gets something far more compelling and does so quickly. We just don't have a good natural understanding about what turns r

Its more that I am surprised they started these projects in the first place. I agree that smart motorways are less safe, and there are better ways to reduce demand (like road pricing). Having said that motorways are still very safe compare

Politicians love big projects. It is much more tangible than most government programs. Your draw a line of a map and then a real change happens in the world. And this government have put much more money into infrastructure than you might

It is a few years late, but on a 10 year program. And it is only around 25% over budget. That is a lot of money to be sure. But compared to other government or corporate programs it seems pretty good. And it will deliver real measurable

You can't base every decision you make on well researched science though. Everyone develops their own heuristics to make decisions. I think naturalness is just one of those. And within a limited set of choices it is probably a prett

Abtract concepts are always somewhat invisible. What counts is having the analytical skills to match your book knowledge.

I think biology played a bigger part than just colonization itself. Europe went to the Americas and brought back potatos and a substantial boost in calorie production compared to wheat. Alongside corn, tomatoes, sweet potato. The Americas

Cars are a fashion item though and that does allow car companies to push products that are not always ideal for how they are going to be used. I am not saying we should ban things neccesarily but some basic consumer protection is a good id

In the UK there is around 1.4 GW installed battery storage capacity and a further 20GW+ in the pipeline. The technology does exist and is mass producible and scaleable. Hiccups in supply are usually more complex than just blaming a single

Technically it is exactly the same as a generator, you sell power at a particular price. From the grid perspective it is exactly the same. The fact that you also consume energy is coincidental. And it can work well with existing grid sys

From zero a few years ago it is amazing. This is an industry that is seriously scalable.

No it could work in other places. You buy 1 unit of energy for £50 per unit. And then sell at £150 per unit, or £90 for your remaining 0.6 units. The profit is from the price difference. You make money from arbitrage. And this is the k

Storage is far easier though if the input power is cheap. Cost per MW is strongly correlated with cost per MWh.

Power grids are designed to have lots of redundancy and tend to have more capacity than is actually needed. It is perfectly normal for large generators to be offline. It might increase prices, but the grid should be designed to cope.

Britain has around 1.4GW of battery storage installed and around 20GW in planning. They are easy to install and mass producible.

That efficiency could be good enough if you can buy the energy cheap and sell high.

The grid is designed to deal with the loss of a power station like this. In fact it does all the time as generators go offline for maintenance etc. Also, the land requirements for this are really modest. Our legacy power station sites are

I think it had an effect on public mood in Vietnam, which is why press coverage was restricted in later wars. Who knows how it could have played out in a modern connected world.

AC cables are just more expensive per km, I think due to skin effects.

More cables could disrupt the sea bed more during construction and cause more harm to plants and animals.

Yes, accept those things are all designed for large scale grid systems.
685.
by 7952 5y ago
Yes. But storage is easier at scale using the existing grid. A large battery storage site can take excess power from across the grid and get economy of scale.
686.
by 7952 5y ago
But these elaborate uses for excess energy are easier to do at scale using the existing grid. You have a specialist centre in a single location that can take excess power from across a large area.

> Distributed power generation is the ideal. Why bother with transporting energy when you can just generate it where you need it? You need to be able to throttle the power output up and down. That is harder to design and harder to make

Lower cost per MW of capacity correlates with lower cost per MWh.

I think we are getting to a place where the use of nukes is so unthinkable that the deterrent effect is reduced. At which point maybe conventional war becomes more possible.
