Well it could be used for your crotch if you are tall enough, or you have a weirdly high crotch with a weirdly short torso. Either way, it’s a sweet-looking fixture with a lot of options. [Hansa via Trendir]

The 2011 Nissan Leaf: It’s going to be the first “mass-market” pure-electric car. It’s not the first electric-car period, but the “mass-market” qualifier makes it OK. I guess. And the 160km range. And it’ll be about $30,000 before a $7500 tax break, so you can afford it. And we love Nissans. [Popsci]

The Sikorsky X2 Helicopter: It’s going to be the fastest chopper in existence based on the fact that there are counter-rotating rotors and a backwards-facing propeller that pushes the whole thing forward. It may not look like a helicopter you’re familiar with, but it’s pure sweetness. [Popsci]

Diamond Interchange: This new traffic intersection type can “reduce clogging by as much as 60 per cent”, which bodes well for drivers everywhere. You don’t need to know how it works, you just need to know that it does, and convince your local MP to change over to this style. [Popsci]

Powergenix Rechargeable AA Batteries: These are supposed to be, thanks to better Nickel-Zinc technology, as good as disposables — but can last up to 1000 charges. They’re not too expensive either, comparatively, at $US15 for four. [Popsci]

Sennheiser HD800 headphones: Sennheiser’s HD series are expensive (boldly expensive), but very much worth it. The 800 is just another reason why you should be taking night classes in order to get a better job to pay for these. $US1400 isn’t something you throw down casually, but if you’re talking sound quality AND comfort (others can do one or the other), you’ll have a hard time beating Sennheiser. [Popsci]

X-Flex Blast Protection Wallpaper: These sticky, rollable, self-adhesive sheets can be applied to any wall that you think will be the subject of explosions. In turn, the walls stay vertical and the occupants inside the building say alive. Popsci says these things kept a wrecking ball from going through pure brick, so it’ll definitely keep your angry teenage kid from putting his fist through your drywall. [Popsci]

Filigent Limited BioMask: A face mask — like the kind everyone wears in Japan when they’re sick — that kills 99.9 per cent of flu viruses in less than a minute. And 100 per cent after 10. A regular mask still holds 50,000 bugs (on average). If you want one of these you’ll have to import it from Hong Kong or Europe, where it’s more acceptable to wear one of these on the street. I should really stock up on these for CES next year; not because it’s going to be a mass of diseased bodies in a confined space, but because Adam Frucci is really disgusting. [Popsci]

Xela Innovations Purleve Hygienic Door Handle: The door handle is actually a sleeve dispenser, so instead of touching poopy metal, you touch a removable plastic sleeve whenever you have to get out from the can. It’s genius, even if it is slightly wasteful to refill sleeves all the time. But if we have no problem protecting our arses from public toilets with disposable toilet rings, this should sell just as well. [Popsci]

Microsoft’s Project Natal: If there’s one game development we’re looking forward to, it’s Natal. Imagine combining the fun of being at home with the fun of moving around in your living room and having a machine know exactly what you’re doing. Perhaps we should phrase it another way: Whenever Mark and I play any game, he says “imagine how great this would be with NATAL!!!!” He actually pronounces those exclamation points out loud over Xbox Live so I get how serious he is. [Popsci]

Bosch Full Force Technology Nail Gun: You might not use nail guns every day, but when you do, you really want to savour the experience. In this case, Bosch uses a secondary air blast that follows the first nail-ejection one in order to return the piston into firing position. So the nail gun literally goes pew-pew with each shot. As a result, the gun is 20 per cent smaller and 10 per cent more powerful than anything else. With one of these, everything you own becomes a board. [Popsci]

The tub also features touch controls and a motion-activated hand shower. Unfortunately, it’s only a concept—but the design was good enough to become a Red Dot 2009 award winner. [Red Dot via Born Rich via Unplgged via DVICE]

Optionally made with moisturising shea butter, the face of the $US8 soap is about the same size as an actual iPhone, and even has icons and a home button.

Other iPhone soap scents include strawberries and champagne, aged merlot, watermelon margarita, peppermint, Oma’s strudel, Coca-Cola, and beer.

And don’t fret Pre owners: the creator also has Palm Pre soap that smells like yummy chocolate truffles. [Two Egg Plants Company via Etsy]

The thinking is that, by fitting around your teeth like some kind of bristly retainer, the 40 second toothbrush can decrease necessary brushing time by 66%. This assumes you were taking 120 seconds to brush your chiclets with a traditional toothbrush, which, let’s be honest, you weren’t.

This brush bears the two telltales marks of a Hammacher Schlemmer product, which it is: it solves a problem that nobody has (an inability to pay attention long enough to brush their teeth) with a method that probably doesn’t work (wrapping your teeth in cupped brushes and vibrating like hell). Oh, I almost forgot about the third mark: it’s $US100. [Hammacher via RedFerret]

In addition to the fish tank base, Hydroco’s Hydroglass unit can feature a 7-head rainbar, heated aquabed, warm water mattress and other accessories when fully decked out. It’s going to start a revolution of laziness in the bathroom. That’s right—sooner or later we will be able to poop lying down. What a day that will be. [Hydroco via Born Rich via DVICE]

The way I see it you have four options: sit directly on the unsanitary toilet, wallpaper the seat with TP squares, use one of those flimsy paper covers, or squat and hover. If you prefer the latter option, but you lack the thigh strength to maintain elevated above the bowl for the duration, this toilet can help.

You see, the user takes a motorcycle-esque stance over the bowl, with their knees inserted into padded grooves to support weight comfortably. Of course, I’m not sure that this concept completely addresses the other major problem with the squat and hover method—(ahem) “discharge containment.” The bowl would probably have to be really wide. Yeah, public restrooms are nasty enough already. [The Design Blog]
