Electric 'flying taxi' prototype unveiled by German start-up

A new “flying taxi” has been unveiled by German start-up Lilium, which claims the vertical take-off craft could be the basis for an on-demand air service within six years.
The electric jet-powered five-seater aircraft is designed to travel up to 300km, a journey that would take it an hour at top speed.
While a smaller version of its novel plane flew in 2017, Lilium said that the maiden flight of a full-scale prototype earlier this month – a brief, remote-controlled test hover in Munich – was a “huge step”.
The firm, which has attracted more than €100m (£87m) in investment since its founding in 2015, has set a target of offering Uber-style, app-based air taxis in multiple cities by 2025.
The latest iteration, with room for a pilot and four passengers, will be the template for Lilium’s mass production model. With sufficient economy of scale, Lilium believes fares would be around $70 (£55) per head for a cross-city hop from, for example, JFK airport to Manhattan.

Daniel Wiegand, co-founder and chief executive, said: “We are taking another huge step towards making urban air mobility a reality. The Lilium Jet itself is beautiful and we were thrilled to see it take to the skies for the first time.”

According to Lilium, the relatively simple design, beyond the 36 electric jet engines needed for vertical take-off and landing, make it more safe and affordable than other planes. Once in the air, the power needed in cruise is little more than that of an electric car, Lilium says. The fixed wing design gives a longer range than competitors with drone-based aircraft, which consume much more energy keeping airborne.

Lilium will now seek certification for its new plane through rigorous flight testing, the next landmark being to move the jet seamlessly from vertical to horizontal flight.
Although many people might have reservations about Lilium’s stated ambition – “a world where anyone can fly wherever they want, whenever they want” – Wiegand said that the firm was trying to meet society’s demands for quiet, green urban air travel.
Remo Gerber, chief commercial officer, said the jet made around 20% of the noise of a helicopter: “You could utilise this in cities where people live, it’s totally electric powered ... This is very different.”
He said that the ambition for an app-based on demand service would not mean “landing in every garden... You’d be working with regulation around the world, integrating with public transport systems where they have them. We’re coming at a respectful way of thinking how people live, how we create corridors and not just fill the skies with these things.”
For people in rural Britain, for example, Gerber said, any disruption would compare favourably to building HS2: “You don’t have to cut through their lovely countryside. You need a little take-off pad and you’re connected to the whole country. Compare that to building roads or building train lines, it’s a fraction of the cost.”

 The market for flying taxis could be worth $1.5tn by 2040, according to a Morgan Stanley analysis, and a host of other eVTOLS – or electric vertical take-off and landing craft – are in development around the world. Uber itself unveiled a very different-looking concept model earlier this year, while Airbus is developing its autonomous Vahana craft. Chinese drone manufacturer Ehang was confident enough to carry VIPs on a helicopter-shaped eVTOL in 2018.

HISTORY OF THE SEX ROBOTS

                       

                       

Sex robots or sexbots are hypothetical anthropomorphic robot sex dolls. As of 2018, elaborately instrumented sex dolls have been created by a number of inventors, but not fully functioning
The development of the sex robot has evolved from sex doll precursors that stem back as far as the 17th century, during which the Dutch sailors created an hand sewn masturbation puppet made of cloth and leather . Many scholars considered this creation to be the direct predecessor of modern sex dolls. Much of the inspiration for creating the modern sex dolls came from mannequin-based art.
By 1968, sex dolls were advertised for the first time in pornographic magazines and became available for purchase through mails. These sex dolls were inflatable with air; consisting of the penetration areas; the mouth, vagina, and anus. However, due to their inflatable nature, these dolls were subjected to deterioration and were not sustainable for continuous use. By the 1970’s, materials such as latex and silicone were widely used in the production of sex dolls to facilitate enhanced durability and a greater resemblance to a human.
currently As of 2018, several new models have been constructed to hold conversations, remember important facts, and express various emotions. One such model is "Harmony", created by Matt McMullen, which is customizable by using a mobile app, where users can choose from "thousands of possible combinations of looks, clothes, personalities and voices to make your perfect companion".
There are ongoing attempts to make sex dolls socially interactive. In 2010, a sex doll called Roxxxy that had the capacity to play back pre-recorded speech cues was demonstrated at a trade show In 2015, Matt McMullen, the creator of the RealDoll stated that he intended to create sex dolls with the capacity to hold conversations. Sexbots with a male design may be referred to as malebots or manbots.
The Barcelona based Dr. Sergi Santos already

developed a sex robot named Samantha; this robot has the ability to switch between a sex setting (which can include Samantha simulating an orgasm) and a family mode. It can also can tell jokes and discuss philosophy.
Also in 2017, Matt McMullen created a sex doll

 and named it "Harmony" which has the capability of learning about the preferences, wants, and desires of the owner. Furthermore, Harmony can smile, blink and frown in a nearly humanlike fashion. She can hold a conversation with you, tell jokes, remember your food preferences, and the names of your siblings. The estimated cost of Harmony is said to be roughly $15,000.
It is said that the skin on doll's face could be peeled off and replaced with another one. Her personality can equally be changed by using the app on his hand held device, this device is also responsible for controlling the sex doll.

Nano robots in medicine

ABOUT NANO ROBOTS

Nano Robotics can be defined as the technology of creating machines or robots close to the microscopic scale of a nanometer (10−9 meters). Nanorobotics refers to nanotechnology, an engineering discipline for designing and building nanorobots. These devices range from 0.1-10 micrometers and are made up of nano scale or molecular components. As no artificial, non-biological Nano robots have yet been created, they remain a pretending concept. The names nanorobots, nanoids, nanites or nanomites have also been used to describe these hypothetical devices.

Nano robots would be used in different application areas such as medicine and space technologies. Nowadays, these nanorobots play a crucial role in the field of Bio-Medicine, particularly for the treatment of cancer, cerebral Aneurysm, removal of kidney stones, elimination of defected parts in the body structure, and for some other treatments that need utmost support to save human lives.
This Nanorobots are nano devices used for the purpose of maintaining and protecting the human body and the structure against pathogens. Nanorobots are implemented by using several components such as sensors, actuators, control, power, communication and by interfacing cross-special scales between organic inorganic systems.

Nano robotic applications 

The application of nano robotics are more as; micro rooties, emerging drug delivering application, health care, bio medical application, cancer therapy, brain aneurysm, communication system and new future nano technologies. Etc
The application of nano technologies in medicine are:
1. Nanorobotics in Surgery
Surgical nanorobots are introduced into the human body through vascular systems and other cavities. Surgical nanorobots act as semi-autonomous on-site surgeon inside the human body and are programmed or directed by a human surgeon. This programmed surgical nanorobot performs various functions like searching for pathogens, and then diagnosis and correction of lesions by nano-manipulation synchronized by an on-board computer while conserving and contacting with the supervisory surgeon through coded ultrasound signals.

Nanorobotics in Surgery


Nowadays, the earlier forms of cellular nano-surgery are being explored. For example, a micropipette rapidly vibrating at a frequency of 100 Hz micropipette comparatively less than 1 micron tip diameter is used to cut dendrites from single neurons. This process is not ought to damage the cell capability.


2. Diagnosis and Testing
Medical nanorobots are used for the purpose of diagnosis, testing and monitoring of microorganisms, tissues and cells in the blood stream. These nanorobots are capable of noting down the record, and report some vital signs such as temperature, pressure and immune system’s parameters of different parts of the human body continuously.


3. Nanorobotics in Gene Therapy
Nanorobots are also applicable in treating genetic diseases, by relating the molecular structures of DNA and proteins in the cell. The modifications and irregularities in the DNA and protein sequences are then corrected (edited). The chromosomal replacement therapy is very efficient compared to the cell repair. An assembled repair vessel is inbuilt in the human body to perform the maintenance of genetics by floating inside the nucleus of a cell.

Supercoil of DNA when enlarged within its lower pair of robotic arms, the nanomachine pulls the strand which is unwounded for analysis; meanwhile the upper arms detach the proteins from the chain. The information which is stored in the large nanocomputer’s database is placed outside the nucleus and compared with the molecular structures of both DNA and proteins that are connected through communication link to cell repair ship. Abnormalities found in the structures are corrected, and the proteins reattached to the Deoxy Nucleic Acid chain once again reforms into their original form.
4. Nanorobots in Cancer Detection and Treatment
The current stages of medical technologies and therapy tools are used for the successful treatment of cancer. The important aspect to achieve a successful treatment is based on the improvement of efficient drug delivery to decrease the side-effects from the chemotherapy.

Nanorobots with embedded chemical biosensors are used for detecting the tumor cells in early stages of cancer development inside a patient’s body. Nanosensors are also utilized to find the intensity of E-cadherin .
5 Anti Hiv using nano technology
The immune system is comprised of two important cell types; the B-cells and the T- cells, The B-cell is responsible for the production of antibodies and the T-cell is responsible for helping The B-cell for making antibodies or for killing damaged or different cells within the body and the T-cell are classified mainly into two types, the "helper" T-cell and cytotoxic T-cell. The T- helper population is further divided into those help B-cells (Th2) and those which help cytotoxic T-cells (Th1) through nano robotics treatment systems, immune systems and operation of Hiv. The immune system is activated. Both B and T cell members respond to the threat, which is a result in the elimination of the substance or agent from from our bodies. Normally, these actions are wonderfully protective of us. The effect of Hiv in the immune system is the result of a gradual elimination of the Th1 and Th2 helper T- cell sub population. Remember about the proteins which envelopes HIV. One of these proteins, named gp120 'recognises' a protein on helper T-cells named CD4 and physically associates with it. The CD4 protein is a normal part of a helper T-cells membrane.

As a consequence of the interaction with CD4 on helper T-cells, HIV spefically infect the very cells necessary to activate both T-cell immune responses. Consequently the virus can multiply, and kill the helper T-cell in which it lives. The fight between the virus and the immune system for supremacy is continuous until the body eventually succumbs, apparently because of the inability to of not being able to produce T-cell any longer. This result in the complete in ability of our body o ward-off even the weakest of the organisms. This acquired condition of immune deficiency is called AID
