Power generator using cycling waste heat hot water/cooling water to drive a shape memory alloy wire actuator piston, which drives a hydraulic transmission and power generator. Made a discovery for high cycle ninitol alloy (10 million versus 1 million cycles for regular NT wire) to make the linear actuator work for industrial applications. Uses direct impingement of hot water and cold water to cycle the actuator though...

Hybrid-Electric Military Motorcycle - Logos New Website
If they make a good multifuel series hybrid, I can imagine a lot of civilians who would be interested. BRD is making the base electric motorcycle chassis, but the multifuel rotary series hybrid generator engine maker is Cubewano (based off an UAV engine they made for a military secret UAV project). The SilentHawk being a two wheel drive motorcycle is interesting as well, but that suggests the possibility that a boost electric hub motor in the front, with a conventional ICE mechanical drivetrain with integrated generator for the back would possibly work as well. But the description was series hybrid so both wheels would be electric.

Sagita - Home
Looks like a semi-hot cycle helicopter, but instead of a potentially more complicated tip jet drive, it appears to use dual contra rotating direct drive turbines to spin the rotors, exhausting into the inter-disk area of the rotor hub. That exhaust choice is a bit odd though, but it might increase local air velocity over the blades.

Evtron | Next generation storage platform
Currently their device, called CELL,is a 4U oversize (length is 45 inches, current standard is 42 (38-48) inches) DAS, mounting 120 3.5 inch SAS HDD. Appears to use 5x24port SAS backplanes. Claims to use a proprietary heatsink/mount system, ostensibly to reduce the airgaps needed for cooling to increase density. No pictures of the insides, so can't tell if hot swappable.

Still, looking at the Backblaze StoragePod for comparison (if not hotswap) which has 15 disks per row in 3 rows, you are looking at maybe 16 disks per row for a exceptionally tight setup, but that comes out to 7.5 rows. If you look at a DataON DNS-1660 (with hotswap), it has 12 disks per row in 5 rows, and roughly 20 inches consumed, so 120 disks would consume 40 inches. Which makes me think it is not hotswappable in the normal sense, to cut down on hotswap caddy tray space consumption, and still leave enough room for for the PSU's. Maybe some backplane chip layout tricks to shorten the length.

Future proof » Tim’s F6 driver guide
Only 3 brands of USB floppy are supported in Windows XP installs when needing a mass storage driver (demarcated in txtsetup.sif) so that HP USB Floppy Drive Key won't work. But if you modify the ISO by changing the txtsetup.sif to add additional hardware vendors, it should work. Though if you go to the trouble of modifying the ISO, you may as well slipstream patches and additional storage drivers from a driverpack.
