Hurlable 360° cam-grenades used by IDF in Gaza

got nades

This seems like a good (but not entirely new) idea. For the price of a wireless camera setup I don't think it matters whether the UK buys them or makes them - this is not rocket science.

That said, the Israelis have a penchant for this kind of thing, and I would expect them to get it right.

As for disabling the grenade with hammer / paint - surely the camera would have served it's purpose? While Terry vandalises the surveillance, a less civilised version can be on its way into the room.

... or out, if the tech-savvy terrorist can think under pressure.

Boffin seeks $300,000 to build eight-wheel 230mph EV

fish for tea, therefore friday

according to wikipedia,

"The car has eight wheels enabling it to be closer to the ground for better traction".

I think I follow this argument, (there's a couple of steps left out).

But what advance in engineering has made this change a good idea? I suspect it's not the battery. Vista SP1, perhaps?

exposure ...

"...radiation could be expected to use up much of an astronaut's lifetime exposure limit."

Can there be a sensible limit to lifetime radiation exposure ?

Even if you gave someone a hefty dose in the last minute of their life, they would be unlikely to er . . give a shit.

This is not quite as bonkers as it seems. It is generally accepted that sending elderly astronauts to Mars would be a preferable, as they would be less likely to suffer from cancer as a result of their exposure during the trip. Not because of any special immunity, just because something else will probably get them first !

A tombstone, I think.

Top aero boffin: Green planes will be noisy planes

I remember seeing an open rotor jet flying at Farnborough in the late 80's

this one I think ...

It sounded slightly different, but not noticeably louder.

Is it just me or did all civil engines sound different back then ?

Nuclear reactors are not suited to an aircraft that needs to carry people or take off and land more than a few times a year.

The reasons are based in science, not engineering, so I don't expect to see them flying around for a while.

Coat ... because I mentioned the S word.
