Urgent Evoke

A crash course in changing the world.

Here's an idea that came to me last night:

So I was lying in my bed, waiting to fall asleep when I heard a small high pitch noise. I lay still a moment before I determined that it wasn't my tinnitus acting up. So I went up and tried to find the source of the sound. It didn't take long before I discovered what made the barely audible screech. It was my cell phone recharger. Apparently I had accidentally left it in the socket when my phone was fully charged, the electricity running through the charger generated the noise.

Since rechargers still draw power when they're not connect to a device, I removed it intermediately. But it got me thinking. This is the perfect example of "It's not a bug, it's a feature". Why not install these gentle reminders in every recharger alike? A small LED, a soft high pitch noise, or something similar, could be used to remind people of removing the chargers when they're not in use. These reminders would only be active when a device is not connected to the charger but still in a socket. Why not add a small LED array on big chargers saying:

"Chargers use energy even if they're not charging. Save money; unplug"

Good points well made. Why not go one further and have a charger that "disconnects" from the socket (perhaps through a breaker) once the device is fully charged? That way no power is wasted if the owner is out of the house or out of ear-shot.

Well worth a +1 for creativity Per

Great idea!

Myself, I keep forgetting to unplug chargers. With electricity bills always rising, such a gizmo would be of great help.

Hey ben good catch! It would be a lot easier that way!

There is a charger made that ejects from the wall when phone is charged.
I wish I had the link, if you search on YouTube it should POP up

Ben said it for me, so I'll follow suit with +1 creativity. Still, as an addon tech, it could be worth some money too. Bells and whistles costt $$ use energy AND are very popular. :) Or...Is there an app for that?

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
