TECHNO THRILLS
minis

Scientists have created the smallest
petrol
engine in the world ( less than a centimeter long not even half
an
inch ), small enough to power a watch or any small gadget.
- The mini-motor, which runs for two
years on a
single squirt of lighter fuel, is set to revolutionize world
technology.
- It generates 700 times more energy than
a
conventional battery. It could be used to operate laptops and
mobile phones for months doing away with the need for charging.
- Experts believe it could be phasing out
batteries
in such items within just six years.
- The engine, minute enough to be balanced
on a
fingertip, has been produced by engineers at the University of
Birmingham
- Al Gore
cries havoc! and says he's committed to eliminating the
threat posed by this internal combustion engine"
Current
events lead me to speculate on how the state will use this technology
to further intrude on our privacy. Ironic isn't it, that the
party of
abortion rests its argument on the "right to privacy," and only in that
one instance?
Here's more examples of V8
and V12 Engines in Miniature

Rodger, went looking around the web to find more on this. Seems the original article was written around 2003, but there has been some updates since (2012).

Did these inspire those advertisements on TV where people working in an office pull a starter rope to turn on their computer? Prescient.
ReplyDeleteOn youtube, there's a guy who runs 'Visible V8' models up to ~7200 rpm. Not too sure what his goal is, but he'll tell you about melted crankshafts and twisted connecting rods, and teflon topped pistons.

As for wristwatch like complexity on mass produced engines, nothing beat the Napier Sabre British Engine on the Hawker Tempest...24 cylinders sleeve valves H engine...extremely efficient...just as unreliable!

Contrast to the unsinkable Pratt and Whitney R-2800's power and simplicity running the P-47(one kept flying after taking 3,000 hits!) One bullet was enough to kill the Tempest...just like with the Mustang!

The 18 cylinders 3,000hp PW engine itself(without gearbox and rear accessories) was only 2.5 feet long!
Oops...here's the Pratt:
