A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted, clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts: 1

All posts must be showerthoughts
The entire showerthought must be in the title
No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- If you feel strongly that you want politics back, please volunteer as a mod.

Solar should be packaged with consumer appliances (lemmy.world)

Like all buildings should have some kind of standard for solar panel placement added or retrofitted with a very low cost modular mounted frame. Then, when you get an appliance it has a built in battery and comes paired with the right size panels that are sized for each region in the local store/wholesale distribution layer.

The whole scheme is hybrid in the first phase of a decade or so while edge cases and issues come up, like how to handle high rise buildings. Then the burden of grid infrastructure is less of a burden on the poor in total because few people are going to replace all appliances in this instance unlike those that can install a whole house solar system. The entire thing would be more incremental and serviceable over time with modularity. It is less efficient overall compared to a single controller and battery but doesn't require large upfront cost or repurchase later down the line.

This isn't that good of an idea. While it seems like a good idea as we skip the loss of DC solar panel to AC mains to DC appliance.

Currently each appliance* you have runs at 110/240 AC and will transform down to whatever DC voltage the device needs.

Solar panels produce DC voltage somewhere between 12v to 52v.

Plugging in a device that expects 12v into a 48v line will blow something up.

*Some appliances like washing machines, fridges, toasters, kettles don't always use DC some will still step down the voltage to something more usable.

The power can easily be addressed in a buck boost topology and matched to the machine in question much better than a general system for the home as it would remove any need to worry about the standard voltages. Match to the appliance's needs directly. Then use a small step down wall wart like plug pack to boost the battery as a hybrid option if needed during the down cycles.
