Straight out of Star Wars comes the potential weapon of the future.

The Plasma Explosion Gun, as deadly as it sounds, is actually a non-lethal gun that’s designed specifically for home defense. It pulses with an invisible laser that super-heats the surrounding air, resulting in a plasma explosion that is strong enough to knock an intruder off their feet. And just in case the plasma explosion isn’t enough, electro magnetic waves cause temporary paralysis. Meanwhile, an integrated camera and microphone are automatically turned on, feeding to an off-site security center that will then notify the police.

Sadly, the Plasma Explosion Gun is still just a concept (designed by Isaac Richardson)… and who knows whether or not there’s actual science behind the intentions.

Let’s go mudding, hybrid style! With the Land Rover DC100 Sport Concept, you can get yourself into some pretty slippery situations and not worry about a thing. The DC100 has the ability to take on the water without flooding out as badly as other cars or off-road vehicles. Its Wade Aid technology increases the height of the vehicle and closes off vent ducts protecting the guts of the machine against heavy amounts of the H20.

Sensors in the side mirrors and the bumpers even help gauge how deep of water you’re dealing with for a safe all-terrain vehicle. The engine is four-cylindered and 2.0 liters. The auto transmission goes up to 8 speeds and the vehicle itself, as mentioned before, has hybrid capabilities for better gas mileage and will look great next to your Lexus LF-LC. No price yet as it’s just a concept, but stay tuned. Land Rover won’t want to keep this baby off the market for long.

Let’s do a psychological exercise – I’ll say a word and you say the first American car company that comes to mind.

“Luxury.”

If you said anything other than “Cadillac”, then you did it wrong.

The Cadillac Ciel Concept takes drivers back to a bygone era of roomy interiors, four-seat convertibles and smooth styling. But behind the classic lines lie a hybrid lithium-ion battery and 3.6L V6 twin turbocharged engine, power-assisted transmission and as many accoutrements as you can squeeze into an automobile.

The exterior features four full-sized doors and suicide doors in the back, just in case Prohibition makes a second appearance and you need to lose the feds after a speakeasy raid. All over the Ciel, you’ll find polished aluminum, wood, leather and 22-inch rims.

This car is too pretty to stay a concept forever. Cadillac better put this beauty into production tout suite – we need a little eye candy to break up the monotony of SUVs and mid-sized sedans on the road.
