Africa might leapfrog straight to cheap renewable electricity and mini-grids.
Apart from speckles of light around the biggest cities, much of Africa is dark.Of all the measures of the continent’s poverty, few are starker than that about two-thirds of its people have no access to reliable electricity. The number of Africans without any power is 620 million, most of them in villages and on farms. The African Progress Panel (APP) found that in nine African countries fewer than one in five primary schools had lights. A study by the World Health Organization found that about a quarter of clinics and hospitals in 11 African countries have no power of any kind, and many of the rest get it from generators that often break down or run out of fuel. If you don’t have electricity you don’t have a fridge, and if you don’t have a fridge hospitals can’t store vaccines. They rely on expensive backup generators, so the electricity they use is among the costliest in the world. This is the biggest single barrier to development.
Adding a house to the grid even in a compact country such as Rwanda typically costs about $2,000, which is more than the country’s average annual income per person. The APP reckons that expanding grid power across Africa to reach almost everyone would cost $63 billion a year until 2030, compared with the $8 billion a year that is being spent now.Continue reading HUG THE MINI GRID 2→
TheHUGis a damless system that uses kinetic power of moving water. Rapids can add 70 MW power without impacting on the environment. Africa could benefit from its kinetic power of water from rapids. This would provide a return on investment within just a few years.
A Funnel HUG can be adapted to capture kinetic energy in the form of electricity from the tail race of a dam.
Now let’s explain the real reason for the HUG: POWER
The formula for Kinetic Energy is KE= ½ x A x V 3 x (.35) efficiency (A = area swept; Velocity). The area of the throat of the HUG is 3.26 m2
Kinetic Energy = ½ x 3.26 m2 x (7.7 m/s*)3 x .35 = 260kW/turbine x 6 = 1.56 MW
Acceleration = a = g (acceleration of gravity) = 9.8 m/sec
(Final Velocity)2 = 2 x a x s (2 x 9.8 m/sec x 3.05 m)= 7.7 m/sec
Our solution lies in a hydro kinetic energy system called theHUG: Electricity in Remote Areas created from moving water. Electricity supply is worse in rural areas where four out of five people in Africa, are without electricity. The rate of rural electrification is lower than in any other continent. The proportion of people in Africa still depending on inefficient traditional energy sources is higher than in any other continent.
We have developed the ProprietaryHUG, based on the physics of the vortex, which will revolutionize hydroelectric energy. This new damless development of a submerged helical pathway is capable of extracting huge hydro-electric power from rivers, rapids or small waterfalls at low cost, especially in remote areas of the country where there are no dams.
HUG (Helical Unique Generation) is a New Good, which has never been seen before; it substantially deviates from any other good or service produced before. Over the past decades, no major breakthroughs have occurred in utilities.
The river flows into a pencil-shaped construction, called a HUG, which uses a helical turbine to power a large irrigation pump without the expense of electricity or diesel . When we direct the water to flow at its natural mode, it hugs the inner wall. This kind of vortex motion tends to accelerate and contract the stream of water four to five times faster than the river velocity.
