(PhysOrg.com) -- A team of scientists led by NASA space scientist James Mason have proposed the idea of using a mid-powered laser and telescope to nudge pieces of space junk out of the way and slow it down to avoid collisions.
Cal Poly engineering student Alexandra Kline had a crazy idea: What if we could help competitive runners train by allowing them to race against a visual marker? Runners are constantly trying to improve the efficiency and quality of their workouts, and in a sport where success is…
There has been a movement for achieving this for decades now. The tech is getting better all the time and they look so much better than firey pollution that harms animals.
Seb Lee Delisle is your man for this. He is on a mission to replace fireworks with laser shows. Check out some of the stuff he does with lasers in the UK and elsewhere.
To improve communication between spaceships and satellites, it’s out with the old radio-wave reliance and in with the latest in laser-based technology.
This is amasing – better is that eco-activists and artists with laser lighting equipment could go around projecting environmental messages onto waterfalls in inner-city fountains near busy roads.
Saw the idea of projecting on to water years ago and often wondered what real-life applications it could have. So I guess this is it. Any more examples on how this could be used?
Would be good if they played a sound while you crossed too!

Aug 7, 2012 - This may not be very exciting to most, but as a piano player I find it extremely cool. Newly painted zebra crossings in Warsaw have been given a new shape. I absolutely love it!!!
Think its just a concept/idea rather than a thing. Though not sure. It says in the Wired article that it could project silhouettes of the pedestrians behind it, so the motorists are aware that there are lives behind the barrier, that don’t want to be extinguished. Would this type of thing help though? Motorists that ignore lights are just as likely to ignore laser lights too right?
Laser experts, we need to know something: Would this work? The Virtual Wall is designed as a replacement for traffic lights and if made would use “plasma laser beams” to project silhouettes of moving people into the path of oncoming traffic. Supposedly this would calm traffic and make drivers mo... Read more
Wow, I found this from a Google reverse image search. It’s a “virtual wall” and looks like they made it over a decade ago, why aren’t they all over the place already?
The Virtual Wall provides a barrier made up of plasma laser beams depicting pedestrians doing what they do best and any car that crosses that barrier suffers the consequences. Okay so maybe those lasers aren’t powerful enough to do any harm but the effect is enough to make drivers and pedestrians ... Read more
Great idea, not sure how the pen would detect the 2 laser beams have crossed each other or the dots are in the same place on the wall, but would love this for the pens I have. Recommend these btw
Artist and filmmaker Robin Bell projected the words "Pay Trump Bribes Here" onto the Trump International Hotel in Washington, D.C. a few days ago. Is this criminal trespass? Grounds for a civil lawsuit? Or can you do it too?
“News Puff” Purpose: We will project clips of the corporate news media onto smoke escaping from the Cloud Factory. The amorphous quality of the smoke will challenge the fixed, clearly-d…
The secret story of the development of cloud generation devices told by a participating expert in the Cloud Project challenge to project images onto clouds.
Pollution in China is a very real, very serious problem, with around 750,000 people thought to die prematurely each year because of it, with most of these caused by air pollution, both outside and...
Asteroid laser ablation is a proposed method for deflecting asteroids, involving the use of a laser array to alter the orbit of an asteroid. Laser ablation works by heating up a substance enough to allow gaseous material to eject, either through sublimation (solid to gas) or vaporization (liquid to ... Read more
Lasers in space don’t inspire confidence when they can be used as weapons against other countries’ satellites or spacecraft.
Several space agencies, including NASA, are already researching the use of lasers to vaporize space debris.

Very soon, space will become as polluted as our oceans, the only difference being that space debris is more lethal when it starts falling to earth.
Trackpacer is an iOS-controlled LED-based pacesetting system that is being tested and refined with university running teams.
Easier might just be to put them on a treadmill that goes the pace the current record breaker achieved. No?

This already. Lasers might work better, might not. Early days.
coming to an orbit near you.
I loved this idea since I heared about The LLCD. They are coming and once they start, just try to stop them.
Could be dangerous adding all that water to the road surface, unless you used something like a water repellant covering.

So cool, in the UK, you would just need the projector and use the regular rain 😉
You can’t project lasers onto nothing, but you can use clouds or mist like this idea https://ideamill.info/waterfall-road-signs/
We should have these crossing laser walls on the end of groins and piers in Brighton, and the gay lights they have in Madrid.
The UK has a cheaper solution, ain’t seen one of these but there was one in London.

Better for art no?
Didn’t realise this was a thing til now. Brilliant. http://www.creativeguerrillamarketing.com/guerrilla-marketing/12-must-see-guerrilla-3d-projection-mapping-examples/
May be illegal but it’s easy and effective 😉
Interesting idea. Looked this idea up and there are some legalities involved.
it works even better if you project messages onto smoke – SHAME THE POLUTERS! WE ARE WATCHING YOU
japan seems to be going ahead with this already…
this is a bit weird tbh
Or use the laser to defelct it into an orbit where we can mine it easier? Just an idea.
One for djs but I want one for my room so I can visualise the waves I am hearing. Maybe some sort of osciliscope would do it.
Steve Moulde nailed this – surprised it isn;t a product already
this is being tested atm.
