Uses a closed loop ICE of sorts, using input hydrogen/methane and oxygen along with working fluid argon. Burn in a piston, condense out the water, membrane filter the CO2, and recycle the argon back to the cylinder.

Enhancing Mechanical Properties of Pervious Concrete Using Carbon Fiber Composite Reinforcement | Journal of Materials in Civil Engineering | Vol 30, No 3
permeable concrete normally sucks, but throwing ground up waste carbon fiber into it makes it strong enough for actual usage, particularly for road/ground cover where you want rain water to pass though into the ground reasonably quickly, rather than collecting pollution then ending up in storm sewers..

Interesting chinese work on using EoL C-band transmitter GEO satellites that have drifted off-plane as a pseudo-GPS system with potentially equivalent performance to GPS at substantially lower cost. I assume there will also be a terrestrial repeater network, likely cellular tower based, for improvements in urban canyon environments. The interesting question is will any existing satellite operator be wiling to rent their EoL but still operable satellites, as this can be considered part of a military weapons and navigation system potentially. The alternative is chinese GEO sats having the capability baked in to improve usefulness at EoL. They only need 4 SIGSO sats and 2 GEO sats for the minimum constellation, ostensibly covering mainland china.

Floating Island Southeast
Interesting artificial bioremediation platform, using recycled plastic and foam to make essentially hydroponic mounts for plants, which free float in lake or river water. The plants pierce the matting, with roots dangling below, offering bioremediation of local water.

NASA - OMEGA Project
Interesting idea of feeding effluent/wastewater/sewage into ocean floating clear tubes to make algae and clean the water. End run around the issues of fertilizer/nutrient feeds for algae production, algae growth medium location, facility structure cost and location, and nicely deals with the wastewater output of sewage treatment facilities.

Transatomic Power
Appears to be a single fluid molten salt nuclear reactor running on LWR/PWR waste mixed into the salt. Company is structured similar to a fabless semiconductor company startup, where they license their design to actual general contractors. LFTR still seems like a better choice...

CO2-Free Engine Powers Up
A magnesium burning steam cycle engine, with a proposed regeneration of magnesium reactant from magnesium oxide cycle output via solar powered laser. I wonder what the energy costs of regenerating the reactant are, because the laser is energy intensive, and there probably needs to be some mechanical treatment of the magnesium to make it a fine powder.

Oceans of plastic
Okay, the idea is attractive, but collecting all the microscopic trash plastic particles without killing off huge amounts of local life will be hard. Any driftnet approach will kill all animals collected by design unfortunately.

Vac from the Sea
Nice little PR campaign. But the seed for thought is, large tuna fishing fleets are increasingly unsustainable due to reduced catches. Retrofit the fleets for recovering plastic from the great pacific garbage gyre would be a huge PR move. I'm looking at you Japan.
