Moment Cancelling Engine | Dan Gurney's All American Racers
Interesting tandem twin motorcycle engine that in theory cancels crankshaft vibration, but while a 4 stroke it sends both pistons down at the same time, so wouldn't there be hammerblow type vertical vibration? The patent covers an intake optimization trick that may be the more applicable innovation.

Wallet TrackR
Interesting wallet tracker tag concept. Using Bluetooth 4 low power, their standalone tag claims 1.5 years. Which is a considerable improvement over other wallet tracker tags, which typically only last a week between recharges. Though the flip side problem is only the iPhone 4S or later have Bluetooth 4, and hardly any android phones feature it, so this is effectively locked to Apple products for the time being.

ck :: VMware ESXi 4.1 does not use whole disk capacity for VMFS3 ::
So, the VMware ESXi 4.1 installer is dumb and won't slice up a large local RAID volume sanely if it's over 2TB to create multiple datastores or a single datastore with multiple extents. You could try to pull the following stunt, or resign yourself to fate and split up the RAID volume into 2TB virtual disks...

Ecomotors Opposed-Piston Opposed-Cylinder Engine Could make Class 8 Trucks 45% More Fuel Efficient
Interesting opposed piston engine concept. Each opposed piston cylinder set/module consists of pairs of inner and outer pistons. By putting the inlet and exhaust ports at opposite ends of the cylinder, you get better fuel burn, and potentially easier valve systems. Opposed setups get some nice balance going, and because it is "flat" engine you could potentially put it under the floor/bed of a vehicle rather than in the front, for better weight balance (provided you are using all wheel electric drive, which is not unreasonable since this engine concept uses an electric turbo/supercharger so you will in principle need a large generator/alternator attached to the driveshaft anyways). I wonder what would stop you from using a concept like this for a diesel cycle, since it is functionally a two stroke based cycle?
