Voltage dividers that divide by 10, or 100, or 1,000 are tough with standard resistors. The numbers do not come out exactly with standard resistors. By adding one resistor to the divider it is possible to get the division ratio exact (not counting resistor tolerances).
Biotechnology firm Joule Unlimited may have come up with a game changer in the quest for economically viable biofuels. Joule Unlimited received a patent for “a proprietary organism” – a genetically engineered cyanobacterium that produces liquid hydrocarbons: diesel fuel, jet fuel and gasoline.
IBM has announced a really fast power transistor. Of course power is a relative thing. At the frequencies involved power is a relative thing. I'd say they would be doing good if they could get between 1 and 10 watts out of the device.
Fusion is the power source of the future, goes the old saw. And for fifty years, it has always been "fifty years in the future." That may be changing with a number of new small fusion projects in the works or doing actual experiments.
In my last post I discussed Forth as a language. A language that is based on a virtual machine. What if that virtual machine was turned into a real machine? Good things. For one operations can be done in parallel. Returns can be automatically initiated at the end of an instruction cycle.
Since I wrote Neighborhood Development Package on November 11, 2006, I have been thinking about the pieces needed to make the system work 24/7. The full article is below but let me give you a short review. My idea was to electrify a neighborhood in order to educate, communicate, and pump water.
