Two of our biggest environmental problems are the tons of unusable plastic waste, and the tons of carbon dioxide (CO2) which are released into the atmosphere in smokestack emissions. A new process is claimed to use the former to trap the latter.
The procedure begins with plastic waste being ground into a powder, after which it's mixed with potassium acetate – that's the unique part – and then heated at 600 ºC (1,112 ºF) for 45 minutes. Doing so renders the plastic powder into sorbent particles filled with nanoscale pores, which are very effective at trapping airborne carbon dioxide molecules.

The first vertical test shot of Green Launch's hydrogen-powered impulse launch cannon.
The hydrogen cannon can be fired every 60-90 minutes, sending its hypersonic projectile skyward where it'll "penetrate the atmosphere within a minute and shed its aeroshell." Low earth orbits between 300-1,000 km (186-621 miles) can be achieved in under two hours, and some much quicker.

Electric chopsticks that make low-salt food taste salty developed by Meiji University
One of the big drags of getting older is not being able to eat with abandon any more. Nowadays just looking at the amount of salt my kids pour onto their food is enough to give me heart palpitations, but it sure would be nice to indulge in those strong flavors without risking a lifestyle disease.
Food producer Kirin and Meiji University seem to agree and through extensive research have developed a pair of chopsticks that can stimulate the taste of salt in foods with low salt content. This still unnamed device does this simply by sending a weak electric current right into your food.
