iPhone 5 will support 4G networks "around the world"

The iPhone 5 will work on LTE networks "around the world", the Wall Street Journal reports. That means if you use one, you'll be able to jump between high-speed networks as you trot around the globe. Though there is one rather massive caveat: it won't work on every network, according to the Journal's sources.

Drat.

Speculation has been rife that the new iPhone will be 4G after the latest iPad launched with LTE support in the US. Other manufacturers -- like Apple's arch-nemesis Samsung -- have launched mobiles that support LTE (commonly referred to as 4G), but locked to one region. So if you bought a Galaxy S3 in the US, you wouldn't be able to use an LTE network anywhere else in the world.

Apple won't be the first to come touting international LTE connectivity. The Nokia Lumia 920, announced this week, supports five bands of LTE. But it just isn't possible yet to make one phone equipped to work on all LTE networks across the world. We still haven't got one in the UK, for starters, though Everything Everywhere is expected to roll one out in the coming weeks.

The iPhone 5 will be announced on 12 September -- that's this Wednesday. Last week Apple sent out an invite for the event, with the shadow of the 12 making a 5, so it's a dead cert the handset will be unveiled. It's expected to pack a 4-inch screen, high-speed LTE access, and a faster processor.

Apple marketed the latest iPad as 4G, but had to climb down after people complained it only works on some LTE bands across the world. So hopefully Apple will be a bit clearer with the next iPhone.

Tata air-power car looks like robot ladybird, may save world

Indian car maker Tata has constructed a prototype air-powered car, that as well as looking like a massive robot ladybird might just be the next big thing in clean energy.

The company, which built the 'world's cheapest car' and then covered it in gems and also makes terrifying war vehicles completed testing on two vehicles that are powered by compressed air back in May. A joint-venture with MDI, the prototype-stage 'AirPod' cars apparently cost just €1 per 200km, or £0.00631899077 per mile.

Despite looking like the worm car from the Busy World of Richard Scarry, the experimental automobiles are no slouch in the speed department, clocking a speed in the vicinity of 70km/h. I wouldn't attempt a speedy corner in one if I were you, though.

The cars seat three people, which is rather impressive for its small size, but won't win you any style points if you try cruising around town in it. Unfortunately, despite being surrounded by the substance that powers its motors, you'll still need to pull into an air-pumping station to fill it up.

Compressed-air power is still relatively unproven, and not without disadvantages (thanks Wikipedia). For example the compressed air must be completely dehydrated, and the energy conversion involved can be an inefficient process.

Still, I can't fault progress on any tech that could reduce our dependence on non-renewable fuels. Motor-makers are slowly moving toward more environmentally friendly vehicles, with VW mocking up a concept electric Beetle and the Nissan Leaf proving a fabulous -- if pricey -- electric motor.

Meanwhile the Tesla Roadster is doing its best to prove that non-petrol-guzzling motors can still look a bit like the Batmobile.

Fingers crossed Tata can make progress on its air-powered car, but in the meantime DMC is beavering away on the electric DeLorean, which boasts 35kW of power and doesn't even require a Flux capacitor to make it go. Check out the video below.

Would you drive Tata's mecha-ladybird air-powered car? Is air-power the future or should we focus on the electric variety? Let me know in the comments or on our Facebook wall.
