More than one (or larger) electrical energy storage battery?
There are various reasons to want a second battery, and a second battery is less helpful to some of those reasons than others, so there’s no simple answer. But if I had to make a general recommendation, it would be to get a second one because it’s an important factor in going all electric; that…

A look at the production and finances of my Tesla Energy system
There are so many factors that affect how a solar energy system will perform and behave, including latitude and longitude, house construction, house orientation, roof shape, trees, neighboring buildings, nearby mountains, HOA, utility rates and regulations, family size and habits, whether you drive an electric car and how much you intend to charge at home,…

Home Electricity Fundamentals
Electrical Energy Fundamentals While energy generally flows in one direction through the network of wires in your home — from the grid, towards your outlets — they don’t have to. You could plug a generator into any outlet in your home (but don’t do this, it’s dangerous) and energy flows “backwards” from that outlet to…

Reader-augmented Writing
Words gave us the ability to effectively share ideas and knowledge, and writing allowed those words to spread further and be carried across time. The printing press accelerated that spread, and electronic mediums allowed even more people to share ideas more quickly. Yet articles and books — even e-books — are still largely static and…

Containerized Passenger Transportation
Getting someone from point-A to point-B will often — even in the distant future — involve a variety of methods of transport. For example, getting someone from their home in San Francisco to an office in Los Angeles might primarily (the majority of the distance) be served by something like high-speed rail or Hyperloop. However,…

HTTP Status Codes 401 Unauthorized and 403 Forbidden for Authentication and Authorization (and OAuth)
When a client requests a resource from an HTTP server and it’s not allowed to access that resource, the client needs to know enough about why in order to present the right message or options to the user. Basically, we need to know whether the user can do something about it or not. HTTP status…
