Olds Elevator - Vertical Conveyor Technology: new Solutions in Material Handling
So this is the inverse of an achimedes screw, where the auger/screw is stationary, and the casing is turned, which makes some things easier mechanically

Interesting design, using perching leg jumps and a blown wing upper surface jet for enhanced lift in a STOVL arrangement. Sorta bird like.

Hybrid Quadrotor
Interesting hybrid mixed propulsion VTOL quadcopter drone. Essentially a conventional flying drone with separate secondary lift engines, but while forward flight is done with a gasoline powered primary engine with high endurance, the secondary lift engines are effectively a stop rotor electric quadcopter which needs a short but very high power burst for vertical ops. So this basically adapts the different powerplants to match their advantages.

Up Mouse -- Indiegogo
For some people with RSI who can still painlessly use finger lifting motions, a new ergonomic mouse for you. No scroll wheel though (why not some kind of scroll slider, constant force button, or a trackpoint like switch under the thumb?)

Propulsion Systems for small and light aircrafts | Micro-Turbofan™, Micro-Turboalternator™, Distributed Lift
The image is not helping in visualizing a power turbine occurring IN FRONT OF a combustor, especially how one transfers compressed air from the compressor to the combustor through the turbine wheel. Seems they are doing a trick where they use a centrifugal compressor, and rather than having a fixed stator correcting the swirl, they allow power recovery of the swirl directly to power the bypass fan ring (pre-combustion power turbine), then move the air towards the combustor (secondary compressor here too?), then on to the post combustion power turbine which is shaft linked to the first stage compressor. So they are probably trying to get too much pressure from the stage compressor, and trying to avoid a HP/LP post combustion power turbine setup. Attractive for some uses.

The DIRECT guys are proposing Leviathan, an update to the old Truax Sea Dragon design using annular aerospike rocket engines. Which is exactly the idea I was kicking around with college friends back before 2000. Sea Dragon basically revolved around the logical end to the big dumb booster argument, making a rocket so large that certain materials handling issues become easier. Namely, using submarine pressure hull manufacturing techniques on half inch thick steel plates formed into a cylindrical tank body. You build this in a shipyard, not a clean room hangar. Due to size, sea transport and launh is must, but that ends up making a lot of other things easier. Leviathan neatly sidesteps one of the issues with Sea Dragon; the second stage expandable nozzle skirt. Aerospikes get almost equivalent performance for less complexity and risk. Reusuability is easier at this size, and sets the ground for SSTO.
