Can Transistors Be Made To Work When They're Off? 89

An anonymous reader writes "Engineers at the Belgian research institute IMEC are looking at the use of silicon transistors in the sub-threshold region of their operation as a way of pursuing ultra-low power goals. A chip the engineers are designing for biomedical applications could have blocks designed to operate at 0.2 or 0.3 volts, researchers said, according to EE Times. The threshold voltage is the point at which the transistor nominally switches off. Operating a transistor when it is 'off' would make use of the leakage conduction that is normally seen as wasted energy, according to the article."

Those issues can be addressed by particulate filters and urea injection, as the current diesels from VW/Audi, BMW and Mercedes demonstrate. I'm familiar with the VW/Audi technology, having just bought an A3 TDI -- their 2.0l TDI engine uses a particulate filter & is 50-state legal. Their larger engines use urea injection, as do the BMW/Mercedes -- the urea reacts with NOx to produce CO2 and NH3 -- the NH3 is subsequently catalytically reacted to produce N2 and H2O.

If you think the police don't care that much then you must not know how they can take everything you own over simply having an immature plant in your home. Dealing or not dealing, if you're manufacturing they will probably own you and all of your possessions.

What's worse is they will also take your WoW account, shard all of your purples, and sell all of your gold for money to fund their War on Weedcraft.
