Lazareth LMV 496 Transforming Jet Hover Bike

This is the Lazareth LMV 496, which the world’s first transforming flying electric motorbike.

Lazareth have a jet engine in the hub of each wheel, and hydraulic actuators that tilt the four wheels out and up, forming a configuration something like a jet-powered hoverbike.

In it’s normal bike form, it is certified to ride on the road, just like the LMV847 Quad bike.

But the main difference between the 2 bikes is, at a press of a button the bike starts it’s transformation. Firstly 2 centre stands come down to support the weight of the bike.

Then each wheel tilts up, so the jet engines in the hubs are now facing down, and after waiting about 60 seconds for the jets to pre-heat, you can lift off.

The Lazareth team will be bringing the Hover Bike, to Gitex computer & electronics trade show in Dubai in October 2019, and will launch pre-orders there at a price of €496,000 euro or about $560,000 US Dollars.

For $150,000 you can now order your own Hoverbike

Circa 2018

After first spotting this crazy looking motorcycle-styled hoverbike in early 2017, we were skeptical the contraption would ever move beyond just an odd engineering curiosity. However, Russian company Hoversurf has just revealed its hoverbikes are now ready for production and preorders are open, with delivery scheduled for sometime in 2019.

Ever since the Scorpion hoverbike was revealed we seriously questioned its safety, with such a crazy close proximity between spinning blades and fleshy legs it seemed like a device only really suitable for “aspiring amputees”. Nevertheless, Hoversurf has rapidly moved from ambitious prototype to commercial aircraft, first revealing a deal to sell the aircraft to Dubai Police, and then more recently passing the US Federal Aviation Administration requirements to be classified as a legal ultralight vehicle.

The plan to classify the hoverbike as an ultralight vehicle resulted in some minor design tweaks to fulfill the legal requirements of the classification, but this final commercial iteration is still, at its core, the same crazy quadcopter hoverbike.

Flight of an aeroplane with solid-state propulsion

Circa 2018

Since the first aeroplane flight more than 100 years ago, aeroplanes have been propelled using moving surfaces such as propellers and turbines. Most have been powered by fossil-fuel combustion. Electroaerodynamics, in which electrical forces accelerate ions in a fluid1,2, has been proposed as an alternative method of propelling aeroplanes—without moving parts, nearly silently and without combustion emissions3,4,5,6. However, no aeroplane with such a solid-state propulsion system has yet flown. Here we demonstrate that a solid-state propulsion system can sustain powered flight, by designing and flying an electroaerodynamically propelled heavier-than-air aeroplane. We flew a fixed-wing aeroplane with a five-metre wingspan ten times and showed that it achieved steady-level flight. All batteries and power systems, including a specifically developed ultralight high-voltage (40-kilovolt) power converter, were carried on-board. We show that conventionally accepted limitations in thrust-to-power ratio and thrust density4,6,7, which were previously thought to make electroaerodynamics unfeasible as a method of aeroplane propulsion, are surmountable. We provide a proof of concept for electroaerodynamic aeroplane propulsion, opening up possibilities for aircraft and aerodynamic devices that are quieter, mechanically simpler and do not emit combustion emissions.

This is how India can become the next Silicon Valley

If India can continue to develop its urban centres and promote a Silicon Valley spirit of entrepreneurship, it could be in a prime position to achieve global tech hub status. Bengaluru (formerly Bangalore) in the south and Gurgaon in the north are two tech-savvy cities emblematic of India’s rapid urbanization. The country is set to become the largest contributor to the world’s urban population.

India has long branded itself as the world’s leading outsourcing destination for global companies, particularly for those in the technology sector — but in the Fourth Industrial Revolution, the time is ripe for the world’s most populous country to reinvent itself.

There is a burgeoning start-up and innovation culture, as shown by the Global Innovation Index, where India has improved its ranking from 81 to 52 between 2015 and 2019. In addition, the country has improved its reputation in terms of the risk posed to foreign investments and, in 2019, ranked third in the world in terms of attracting investment for technology transactions.

To maintain this momentum, India needs to further improve government regulations to encourage support for technological innovation, train tech talent and incentivize it to stay in the country and continue to improve its risk profile by attracting significant foreign and domestic investment in technology. Provided these favourable conditions can be met, India has unmatched potential to become the world’s next Silicon Valley.

‘The next era of human progress’: what lies behind the global new cities epidemic?

This new breed of city takes various different forms, from government initiatives, to public-private partnerships, to entirely private enterprises. Many are being used to jump-start economies in the developing world, with masterplans carefully calibrated to attract foreign investors and treasuries looking to sink their funds into something concrete. They provide a powerful means for wealthy countries to expand their strategic influence abroad, with the construction of new cities acting as a form of “debt-trap diplomacy”, tying host nations into impossibly burdensome deals. They are billed as a panacea for the world’s urban ills, solving overcrowding, congestion and pollution; yet, more often than not, they turn out to be catalysts for land dispossession, environmental degradation and social inequality.

The feature Kim enjoys most is a small touchscreen display on his kitchen wall that allows him to keep track of his and his wife’s consumption of electricity, water and gas and, most important, compare it against the average statistics for the building. Flicking between the screens of bar charts and graphs, a broad grin spreads across his face: for yet another day running, they are more energy-efficient than all their neighbours.

From their living room window at the top of one of the city’s new residential towers, a panorama of downtown Songdo unfolds. Across an eight-lane highway lies Central Park, a broad swath of trees surrounding an ornamental lake, flanked by rows of glass towers with vaguely jaunty silhouettes. Armies of identikit concrete apartment blocks march into the hazy distance beyond, terminating at a Jack Nicklaus-designed golf course. It looks a lot like many other modern Asian cities, a place of generic towers rising above a car-dominated grid. Public life is mostly confined to the air-conditioned environments of malls and private leisure clubs.

Initiated by the South Korean government in the late 1990s, when Incheon airport was being planned, Songdo represents a model that has been replicated numerous times around the world. Begun as a joint venture with US developer Gale International – which has since hawked its “city in a box” kit to other countries – the Songdo International Business District was conceived as a $40bn hub for international companies, an exemplar of sustainable urbanism and testing ground for new smart city technologies.
