There was a period where it was still a skill to know how to use a computer. If you had a computer in your house it was a part of your identity, you were a computer owner. Using a computer was something you did. The computer is a powerful tool, and the user had an opportunity to overcome the challenge of learning how to use it.
Now a computer is an appliance. People know how to do what they do with it, but see no reason to explore farther. They aren’t interested in delving into the device’s potential. Owning a computer is like owning a car. They want it for the function they use it for. Learning more is like learning to change the oil in a car. In principle easy, but more of a chore than an opportunity.
For comparison, the Betacel boasted 25 microwatts per cubic centimeter, and this Betavolt battery appears to have 88 microwatts per cubic centimeter. This will also have a longer lifetime also.
The Betacel was successfully used to power pacemakers. I suspect there will be more applications for power sources in this range today.
