Newly Patented Automotive Technology of Multi Motor Hybrid Cars presented on Go-kart
Kart’s internal combustion engines tend to be in the six to eight horsepower range, again typically derived from some sort of small motorized utility product, but given some tuning to make them race-ready. Weight drops to around 130 kg. Chassis and motor setup tends to be limited because they’re generally used as fleets, with the idea being one is as good as another.
When many people think of a “fast” racing kart they think of a shifter and/or a hybrid karts. A shifter is basically of well-known motorcycle six-speed gearing, enabling the driver to bump up or down a gear very quickly. Engines are still generally 125cc, but the increased mechanical advantage of multiple gears will get you to 100 kmh in less than four seconds. It is not so easy. But for hybrid karts it is not any problem. They powered by an electric motor in addition. In the two motors mode the acceleration is better even without six-speed gearing.
The new invented hybrid car takes all advantages of the regenerative braking:
- In electric mode of driving
- In “gasoline” mode of driving
- In both “gasoline” and electric mode of driving
Other advantages of electric mode of kart running are low noise and zero air pollutions.
Articulated suspension of a climbing motorized wheelchair for rough terrains
Articulated suspension off a climbing motorized wheelchair for rough terrains
This invention (including advanced solutions disclosed in issued patent BG 65421 В1), generally relates to personal propulsion devices that are worn on the front of a user attachable to an wheelchair, tri-cycle or other human-powered vehicle, ridden by the user to propel the user and the object. More specifically, this invention relates to various improvements to the configuration of such devices that improve the usefulness and functionality of the device for disable peoples.
The propulsion support unit of U.S. Pat. No. 4,189,019 to Zech, discloses a complex system of levers, springs, turntable and bars on both sides of the users’ body. Both hands and arms are required for controls. The many parts, heavy weight, high cost of manufacturing, hazardous in a fall, and both hands and arms occupied, make this invention less attractive as an alternative form of transportation.
The propulsion means set forth in U.S. Pat. No. 5,222,569 to Martel, discloses a device that imparts thrust “solely to the rear of the pelvic area.” The propulsion device is supported by a pendulum shoulder harness on the user and must be controlled by both hands on a pair of grips and pivoting handles along both sides of the user. The device is located below the axis centered on the pelvic region and the user may not sit in an wheelchair or bicycle car. Further more the users hands would be unavailable to grasp the required maneuvering implements such as paddles, brakes, handle bars, wheels of the wheelchair etc.
The current invention will overcome the above referenced hand and arm requirements. It will allow hands free operation and control of a simple light weight, efficient, economical, device that is adjustable up and down the user’s back. The current invention eliminates the need for any side bar for control. In the simple case – see pictures and video – the propulsion device is foldable and the wheelchair is foldable, as well. In this case a disable man can operate by one hand only with out any sophisticated control units.
An articulated suspension system resiliently supports a wheelchair. The system includes a suspension mount having an upper shackle and a link arm mount. The link arm mount of the suspension mount has an upper pivot and a lower pivot. An axle tube is configured to rotatably support a pair of rear wheels, and an axle tube clamp engages an end of the axle tube. The axle tube clamp has a pivot and a lower shackle. The axle tube includes a link arm tube mount having a pivot. An upper link arm is supported for pivoting movement between the link arm mount upper pivot and the link arm tube mount pivot. A lower link arm is supported for pivoting movement between the link arm mount lower pivot and the axle tube clamp pivot. A resilient member is pivotally connected between the upper and lower shackles.

Platform of a hydrogen powered electric car
The pure hydrogen car are powered by fuel cells. But they do not benefit of regenerative braking energy because they are not equipped with storage batteries.
The e-car chassis relates to an auxiliary frame, comprising a left longitudinal beam and a right longitudinal beam, a front cross beam and a rear bow beam which are welded to form frame structure. See video.
The present design presents a small hydrogen powered electric vehicle with batteries for temporally storage of regenerated energy from electric brakes. Such type of cars is mainly used in personal or in-location traffic. The platform includes vehicle frame, two seats, front and rear wheels, driving means, batteries, fuel cells, steering system, and front wheels suspension system. One frame is arranged in the middle of the vehicle frame and bulging toward front, and the batteries are arranged on the frame.
The front wheels suspension system is fully independent. The rear wheels suspension system is fully independent as well. Two front wheels fit on the front wheels suspension system, and the back edges of the front wheels are located behind the front edge of the batteries; the steering system is connected to the front end of the vehicle frame and moves with the front wheels. The batteries are arranged at the front, to balance the weight of the electric vehicle thus improving the driving security, comfort and steering quality.
An improvement of the energy efficiency of the hydrogen car is based on both patents BG 65421 and BG 65480. They disclose advanced solutions on how to increase the rotational speed of the electric alternator when it regenerates energy back to the battery.

Newly patented hydraulic-hybrid drive systems
Newly patented (patent #BG 65480) Hybrid-Drive Systems has moved the technology one step closer to reality by converting a Fiat Punto to a hydraulic hybrid. The new power train is more efficient than electric hybrid powertains being used in such cars as Toyota Prius and Ford Escape.
But the innovation lies in the Fiat’s trunk. Two accumulator tanks, which resemble scuba tanks, protrude from the left side of the engine compartment.
Charging Plug-In Hybrids On A Smart Grid
The combination of Plug-in Hybrid Electric Vehicles (PHEV) and smart grid, offers a glimpse of an intriguing future and one which could become viable. Generally, the car’s battery pack would be charged overnight, when the demand for electricity is low, as well as cost. Most estimates put the cost for electricity during this period, on average, as roughly as the equivalent of 0.35 eurocent per liter. An additional option is a Solar PV module on the car roof charging the car battery as well. The advantage of a smart grid comes in, when a normal day, from an electrical stand point, is no longer normal.
Charging plug-in hybrids on a smart grid is more than a simple transmission of power to the car’s battery pack when needed. If plans pan out, and plug-in hybrids catch up, the grid and the cars could work in tandem easing the ebb and flow of power in the grid by alternately storing power and supplying power as needed. Advanced solutions of PHEV are available in the following issued patents – BG65421 and BG65420, including advanced intelligent control, wheel by wheel.

PV rooftop and ground systems with Mirrored Reflectors
Renewable power encompasses a range of technologies that generate electricity from renewable sources such as sun, wind and water.
Solar photovoltaic or solar PV as it is commonly known is probably the most flexible renewable power technologies as it can be deployed almost anywhere in the country with a high degree of operational certainty and, with no moving parts, it requires practically no maintenance once installed.
Photovoltaics is the process by which a “semi-conductor” material turns light (“photo”) into a small amount of electricity (“volt”). When the semi-conductor material is formed into a cell and linked to many more cells to form a panel and that panel is linked to other panels the electricity generated can be harnessed by a solar PV system.
A solar PV system consists of a PV array (a number of connected solar photovoltaic panels) that generates electricity, and a dedicated electrical circuit (typically linked into the main building supply) that enables this electricity to be utilised within the building and any surplus exported to the grid.
Our design software calculates and designs the mounting system according to the required standards which affect the solar PV system and its substructure.
In addition to the number of roof connection points to be used, the dimensioning software also calculates the distances of the guide rails and the maximum span width of the various profiles.
The design software enables us to plan the PV system optimally for each location, roof and the used solar panels and to select the best possible type of mounting system.
Our software calculate augmentation effect of reflectors attached to the PV modules in depend on their layout.
Wind and snow load effects. In addition to the PV system’s own weight, the system’s components and substructure are mainly exposed to wind and snow loads. Therefore, each system must be calculated and designed specifically for its requirements and external conditions, taking into consideration the respective regulations.
The exposure to wind loads is mostly dependent on the wind zone, the terrain category, the building’s height, the position of the roof’s centre, the roof shape and slope. Weight loads due to snow are mainly dependent on the snow zone.
The windload and snowload zone, on which the design of the system is based, can be determined for each location.
Ground mounted solar PV systems offer an alternative solution in situations where a building mounted installation isn’t an option.
Systems can vary in size from small, single-figure kilowatt arrays built within the grounds of a building to multi-megawatt “solar parks” or “PV farms” constructed on large areas of brownfield or low grade agricultural land. Regardless of scale, the design and construction principles of ground mounted solar PV systems are usually the same with the PV array being fitted to a dedicated mounting structure fixed directly to the ground and the inverters installed either immediately below or within a dedicated enclosure constructed nearby.
Mounting structures can take many forms but most consist of a metal or “concret-steel” framework set at the optimal pitch and orientation and fixed to a suitable foundation. To maximise system output the structure can be made to be adjustable such that the PV array will track the path of the sun during the course of the day and/or the angle of the sun across the seasons. These adjustable structures can be mechanised and are commonly referred to as trackers.
Ground mounted solar PV systems installed in fields can be constructed in such a way that sheep can graze below the mounting frames. This has the two-fold benefit of retaining an agricultural use for the land and keeping the grass down in order to avoid shading. Ground mount structures can also be designed to provide additional amenity such as shelter as in the case of solar PV “carports”.
Wherever possible we use ground screws to anchor the mounting frames as these are more environmentally friendly than concrete pile or raft foundations. Additionally, when in future the system is decommissioned the screws can be easily removed and the land returned to its original use with minimal reparation work.
Where ground screws are not appropriate, there are a number of alternative methods of anchoring ground mount frames and our engineers can tailor solutions to meet most ground conditions.
You can see at video a compact three axes Sun Tracking System. Thanks to the new invented platform is possible to reduce space between Solar PV modules (and their reflectors) significantly. Reflector augmented Solar PV modules on an advanced 3D tracking construction. Patent pending.
How Can You Boost The Solar Energy Output Of PV Modules?
Photovoltaic modules are widely being used for the converting of solar energy directly into electrical energy. Different techniques, such as retrofitting of reflectors and concentrators are adopted to increase the amount of radiation flux falling on the module; hence the output of the module increases. We are focused on the practical implementation of flat reflecting materials such as flat mirrors, shiny aluminum and white tiles on the performance of a PV module. The performance was compared with an identical module without such a reflector. The reflector fitted the module output based on the maximum power point and showed a significant increase. There was also an increase in the temperature of the module. To avoid high module temperature, a smart control unit keeps a high powered output in real time by tracking the PV-reflector system.

A Jet Turbine Used In A Water Vortex Power Plant
A lot of people believe that we need more innovation and more development before being able to produce clean energy. This is not true. The vortex power plant integrates a jet turbine in a little river, producing electricity on a cheap basis and in a very clean way.
To build a conventional water vortex power plant in a river, the land must have a downward slope (water head) of at least 0.7 meters. In addition, you have to construct a spatial canal and respectively a vortex basin with a canal water outlet.
Our new technology is based on an artificial water head, by creating a down going force, caused by pressure difference between the upper and the lower chamber of the newly invented water vortex promoter. It is a relatively simple facility-fixed direct in-river bed, with slow moving water. It can also be used on a floating structure (e.g. pontoon).
With new technology we can produce much cleaner energy and be much more sustainable.

ROTOJET Turbine Technology
The ROTOJET designs solve the main problems of the conventional propeller (lift and/or drag) turbine rotors by JET peripheral channels (or semi channel) of the blades. The JET channels have two functions:
The fist one is to avoid the tip blade energy loses because of tip vortices.
The second function is much more significant. The second function is acceleration of the fluid current in the JET channel (or semi channel) and its directing towards the back of the correspondent blade, and thus the flowing current to create JET stream. In the opposite direction of the JET flow appears JET force/torque which considerably augments the rotation.
Because of the JETchannels big part of the fluid pressure over the rotor is redirected into JET force and also due to the channels the inductive blade tip losses of energy are vastly decreased.
During last 10 years we are developing a lot of hydro-kinetic power applications. We have tested ducted and non ducted hydro kinetic turbines. The ducted hydro kinetic applications are more heavy and costly. They require more often and expensive maintenance.
The prevailing world wide practice in zero head tidal plants now is to implement simple and low cost duct less Savonius machines. But they show low efficiency. That is why we have focused on number of options to increase the Savonius machines efficiency.
We find that the around rotor water speed and turbulence affect significantly rotor efficiency. We have developed a mats model for it and have developed respective simulator. Based on both the simulator and water test we propose to number of options.
Hydrokinetic Power – 100% Predictable Renewable Energy Sources
River stream energy is more predictable than wind energy or solar power. Tides are driven by predictable and regular gravitational forces between the sun, moon and earth, whereas wind and solar power are governed by solar radiation and the interaction of atmosphere, ocean, topology and earth rotation, which often result in heterogeneous and unpredictable distribution. Natural river systems and man made canal systems operate on the gradient between the precipitation site and the ocean, which normally exceeds the required value to maintain the nominal flow regime and results in soil erosion. It is this excess kinetic energy that can be gainfully employed with extra side benefits, such as soil retention or recovery.
Water has a much higher density than air (832 times), so a single tidal or river stream generator can provide significant power at low tidal or river flow velocities as compared to wind currents. Moreover, because of the smaller value of kinematic viscosity of water (almost 1:20), compared to air, small size blades that operate at high Reynolds numbers result in a significantly improved aero (hydro) dynamic performance in water as compared to air. A wind machine designed to operate at similar Reynolds numbers would require blades 10 times bigger in chord in order to be effective at low speeds.
