Laser

While we may still not have flying cars, robot butlers or food replicators in our possession, you can now order something else you may have long dreamt of. It's called the Photon Matrix, and it uses lasers to track and kill airborne mosquitoes.

Laser light sources for projectors have their pros and cons. The same is true for LED. The MP1 Max from Dangbei teams them up for the promise of "stunning color accuracy, and enhanced viewing comfort."

Startup Valerion ended last year with the most-funded projector campaign so far on Kickstarter with a bunch of affordable premium streaming projectors. We've been bathing in ultra-sharp 4K goodness recently as we tried out the VisonMaster Pro 2 model.

Looking forward to a future where laser beams replace power lines, DAPRA's Persistent Optical Wireless Energy Relay (POWER) program has set new records for transmitting more power wirelessly over longer distances.

XGIMI has updated its funky portable projector line to include a laser edition. The MoGo 4 has been "engineered to resonate with tech-savvy Millennials, Gen Z and Gen A" though there's no reason old coots like me can't join the portable laser party.

Hisense has launched its "smallest, lightest and most portable laser projector to date." The M2 Pro smart mini projector boasts RGB lasers, expands 4K viewing up to 200 inches and pounds out the soundtrack though Dolby speakers.

Hisense sub-brand Vidda has launched a new home entertainment powerhouse in China called the C3 Ultra. The 4K home cinema projector is the first to feature the MCL39 laser light source for high brightness and excellent color performance.

Nobody likes hearing a mosquito somewhere in their bedroom, without being able to see where it is. Well, the Bzigo Iris tracks and highlights mozzies, so you can swat them. It's now 50% cheaper, and doesn't require a Wi-Fi connection.

Space-starved folks looking for a cinematic solution to replace the living room TV may find a good fit in ultra-short-throw projectors. Optoma's latest model delivers "incredible brightness and true-to-life color in a new compact design."

Just when you think you've seen it all, researchers claim to have developed a way for people to see a color the human eye has previously never seen before. They're calling this new hue 'Olo.'

Under specific conditions, lasers can cool things down – and that might just be what we need to tackle way-too-toasty data centers. A new technology called laser-based photonic cooling can target tiny hotspots on chips to zap heat away.

BenQ has created the Home Cinema Series to meet the "diverse needs of home entertainment enthusiasts ranging from beginners to expert connoisseurs." Joining last year's newbie-friendly 4LED projector is a brighter model plus a pro-level laser thrower.
