Fossil-free Steel - Hybrit
All hydrogen reducing steel manufacturing, rather than using carbon/coke. Energy intensive (when taking hydrogen production by electrolysis into account) but "green" (I suppose that includes induction based furnaces). Not actually new per se, just not at industrial levels

Efficient Generation of H2 by Splitting Water with an Isothermal Redox Cycle
Interesting work showing no temperature swing, only the presence of steam, is the determinant in a redox reaction supporting water/steam cracking for hydrogen production at 1350C which is both lower than expected and avoids thermal cycling the metal oxide catalyst.

Fins Formed on Auto Tire to Reduce Air Resistance -- Tech-On!
Weird ribbing on the inner side of the tire creates a vortex in the wheel well, ostensibly keeping air from spilling out of the wheel well and ruining the aerodynamics of the overall car body, so it's a net gain despite the increased air resistance within the wheel well.

Having a regional scale cloud platform be time/location energy cost aware can reduce total costs, if you can shift workloads to cheaper energy zones. Though that requires the power utilities to provide electricity to datacenters at spot prices on a fairly fine time scale.

Honda to Launch High-efficiency Gas Engine Cogeneration Unit -- Tech-On!
Hrm, I would normally suspect a gas engine here implies a piston judging by the mention of a linkage, but that puts a cap on efficiency since you want to avoid predetonation. Interesting implementation of a variable cylinder volume, but couldn't you do that in a simpler way with a prematurely closing intake valve and simply use cylinder/crankshaft inertia to fight the suction that would develop? But why a reciprocating engine? Capital costs? You would think a fuelcell or capstone microturbine would be better...

Hurricane suppression system - Salter Sink
There is a shot of a two stroke system, where the wave action is both pumping warm surface water down and deep cold seawater up. The nutrient rich deep water replicates natural ocean upwelling currents/gradients, which greatly promote surface marine life. Naturally it also cools a slightly subsurface layer, so there are thermodynamic costs since it would sap heat out of the local surface water you are trying to force down.

tripleO · Home
Basically, you treat a surface with a light acid wash to clean pores and microfeatures on a surface and positively charge them, then put the tripleO paint on, where the nanoparticle emulsion is negatively charged, causing the nanoparticle to seek and bond to the microfeatures, effectively filling them and making the overall surface smoother, providing a drag reduction. Apparently for EasyJet, they may be getting up to 2% drag reduction on their airplanes for almost no weight gain using this paint.

Stena Bulk - Stena E-MAXair
An LNG/diesel fueled ship concept with an auxiliary propulsion kitesail, and an air cushion cavity to reduce friction. They probably could have pushed it a little farther with a LNG powered fuelcell driving electric motors (really pushing it is to use auxiliary liquid nitrogen cooling jacket on the LNG tank to supply cooling for superconducting motors).

Ships | Air cushion concept to lower ship’s fuel consumption by 30 percent | ekopolitan
I always wondered how they deal with air bubbles escaping the air cavity towards the transom interfering with the propellers. Shouldn't that aggravate cavitation? Ideally, wouldn't that require a center "trench" run towards the stern to funnel the escaping bubbles, and perhaps waterjets with side intakes?

Idea here is to use near consumer grade (500W) cheap power supplies with fast response factors, coupled with aggressive OS sleep software (and maybe SSD's to cut back on the response start lag of spinning disks), to create server arrays that can shed power load to follow computational demand load. Easier to turn off single power supplies working in an array set to cut power than to tweak a single big monolithic power supply.
