About Us

Most of the world's energy is derived from fossil fuels like coal, oil and natural gas. Only about 6 percent comes from nuclear power plants. But burning fossil fuels emits large amounts of carbon dioxide (CO2) and other gases that trap infrared radiation from the sun. As a result, say many climatologists, our atmosphere is heating up like the inside of a greenhouse, and unless we reduce the rate of CO2 gas emissions, the temperature of the Earth will increase by as much as 6^o F in the next century. Such global warming, according to worst-case scenarios, will cause disastrous floods, droughts and erratic changes in ocean currents, and even will spread tropical diseases and parasites throughout the planet.

Advocates say that nuclear power will help prevent global warming because nuclear reactors produce virtually no greenhouse gases. They point to France, where about 60 pollution-free power plants provide three-fourths of the country's electricity. But critics argue that nuclear power is inherently dangerous and prohibitively expensive. They point out that accidents like the 1986 Chernobyl power plant disaster in the former Soviet Union can result in radiation poisoning that lasts many generations. Opponents also maintain that safely storing radioactive waste is difficult, and that newly designed breeder reactors could make it easier for plutonium fuel to get into the hands of terrorists and others eager to build small-scale nuclear weapons.

Bulgarian energy emits more than 60% of air, soil and water pollutions in our Country. The European Commission is considering imposing an new (2010) EU-wide tax on CO2 emissions on sectors such as transport and agriculture, which are currently not covered by the bloc's cap-and-trade scheme for carbon dioxide. The main problem of the development of renewable energy iis relative high cost of generated electricity.

All projects and Inventions of B 2 B ^TM  network is called to answer the problems caused by low efficiency and high investment costs of the conventional renewable power facilities. The usable renewable power generated by B 2 B ^TM  network members innovative solutions related high efficient energy converters significantly reduced environmental impacts and have a longer lifespan. They are easy to operate and provide a reasonable amount of low cost usable power without requiring frequent or expensive maintenance.

The new invented Wind-PV synergy energy system exploits a passive ground based PV-modules supporting structure as an wind accelerator directed accelerated wind to wind turbine JET blades. This invention is applicable as an upgrade of the turbines operating in Wind Farms, as well. The hybrid systems, generally, is better energy source from energy-system point of view. Another invention related to low cost energy storage system is applicable to all renewable power plants.

All inventions & know-how based on the power analysis and "design-to-cost" approach of  wind, solar, hydro and hybrid  renewable energy systems. According to the issued and pending patents are developing number of advanced renewable power solutions.

Based on new invented ROTOJET fluid kinetic energy converters are developing number of wind and hydrokinetic JET rotor designs. Each of them is full scalable. JET rotor/blades concept require new line of airfoil / hydrofoil  cross section, new plan form, new pitch and twist designs, new hub etc. In addition we have developed complete new ROTOJET power system "flow - blade - rotor - drive train - electric generator - power controller/inverter" . ROTOJET power system design is easy tailored to the specific flow conditions (velocity, turbulence etc.) to achieve much better system capacity factor. Low cost power generation from free river/canal streams by Pontoon Hydro Kinetic Power Barge/Plant with 15 JET Turbines. The barge is a module of hydro kinetic power farm includes number of interconnected modules with semi submersed axis flow JET turbines. The cost of power generated is about USD 0.04/kWh. The JET turbines are world novelty that increase water-to-power efficiency significantly. The JET turbine is a radical new solution based on low cost well known technology. It is fixed blade variable rpm turbine rotating permanent magnet alternator. see a video at  www.youtube.com/watch#!v=47yepY4Mwzw&feature=channel

Wind/Hydro-kinetic power plant with JET blades on vertical shafts (cross flow turbines)based on a floating anchored pontoon structure. Patented JET turbines formed by hollow blades with elliptic-like cross-section. The blades with side inlet aperture and outlet nozzles at blade trailing edge. It is a radical new patented blade design (ROTOJET) that increases flow-to-power efficiency significantly and helps to increase turbine performance at low and moderate flow speeds and in turbulent flow as well.

The Double Hydraulic-Electric (H-E) hybrid car (see video and pictures here) constructed by both patents (BG 65480 @ BG 65421) that uses rpm multiplication to improve the efficiency of the parallel regenerative  braking systems. The new patented Hydraulic-Electric (H-E) hybrid returns above  80 percent of the braking energy back to the wheels.

The developed advanced hybrid car takes synergy effects of both hydraulic and electric regenerative systems.

Different techniques such as retrofitting of reflectors and concentrators are adopted to increase the amount of radiation flux falling on the module and the output of the module thereby increases. WE are focusing on the practical implementation of flat reflecting materials such as flat mirrors, shinny 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 module output based on maximum power point showed a significant increase, and there was also an increase in temperature of the module  See more at: http://tonchev.org/PVparks.html

Because of the expense, political and ecological problems involved with importing oil world,needs electric cars. In fact, the only fundamental impediment to electric cars becoming more important than those with internal combustion engines is the difficulty of building a reasonably priced electric car (or a reasonably priced gas/electric hybrid with the electric motor being the dominant one) that has the range people want. It is also worth noting, however, that a "plug in" pure electric car or a hybrid whose dominant electric motor only relies on plug in electricity and electricity indirectly generated by the internal combustion engine is not so much better than a standard car in terms of global warming. This is because most "plug in" electricity is generated by fossil fuels. Solar power, on the other hand, is both free and does not cause global warming or other ecological problems. Therefore, we believe that the car of the future will have a dominant electric motor drive train whose primary source of power is solar.
