OILOHOLICS: BREAKING THE HABIT

 WILL OIL CONTINUE TO DOMINATE THE WORLD ENERGY?

There is wide consensus that fossil fuels will probably dominate the world energy mix until at least 2040, due to the lack of cheap, practical alternatives.

PROBLEM AREAS

China is still building two coal power plants a week. In both India and China, air pollution and congestion in the biggest cities are already appalling, which will limit the scope for a richer population to buy ever more cars.

India still relies on coal for 58% of its primary energy needs. It hopes to reduce its dependence on oil (28% of the mix) by 10% by 2022, and plans to double the share of natural gas from 7% to 15%

OIL AND WAR

The Muslim world has become polarized into Sunni and Shia and it is fighting international Su-Shi Civil War. Minority Shia, which is only 10% of the Muslim world, are poking the other 90% Sunni in the eye with a stick. Over 95% of terror victims are Muslims.
Nigeria, Libya, Algeria, Yemen, and South Sudan are hot new battle zones due in large part to their oil wealth.

Fracking is the most powerful weapon for geopolitical change in the past decade. It has bankrupted Russia, Venezuela, Nigeria, Brazil and the Arab World forcing deep political change and near revolution.
Today terrorists are starved by the low price of oil–they cannot do their big plans. Weapons and training cost a lot of money.

MOST WORLD GOVERNMENTS

The US is importing half of its oil currently and it will only be the world’s largest producer of oil in a few years and Canada has oil reserves larger than Saudi Arabia.

Political pressure to “keep it in the ground” only works in developed western societies. Yet even Prime Minister Justin Trudeau commented that he knew no country that would allow its oil reserves in the ground to remain untouched.

Governments do not have the political will to implement their climate goals at anything like the speed the Paris agreement envisages. Fossil fuels are a major revenue earner for many governments, usually in the form of excise or hydrocarbons taxes.

Around 18 scientific organizations are telling us that global warming is real because of human cause. These include the American Association for the Advancement of Science, the American Meteorological Society, the University Corporation for Atmospheric Research, and the American Chemical Society, to name just a few. These are not slouch organizations. http://climate.nasa.gov/scientific-consensus/ Continue reading OILOHOLICS: BREAKING THE HABIT

WATER CRISES: COMING CATASTROPHE

If water is not managed better, today’s crisis will become a catastrophe.

As water becomes ever more scant the world needs to conserve it, use it more efficiently. Researchers from MIT predict that by 2050, more than half of humanity will live in water-stressed areas, where people are now extracting unsustainable amounts from available freshwater sources.  We can expect a water crisis that will go viral into a catastrophe if we continue with business as usual.

Many people have a strong moral aversion to paying for the life-sustaining liquid. Some feel that water is a right, and should therefore be free. Others lobby governments to subsidize its distribution to favored groups. This results in vast, but preventable waste.

To make matters worse, few places price water properly. Usually, it is artificially cheap, because politicians are scared to charge much for something essential that falls from the sky. This means that consumers have little incentive to conserve it and investors have little incentive to build pipes and other infrastructure to bring it to where it is needed most.

Researchers from MIT predict that by 2050, more than half of humanity will live in water-stressed areas, where people are now extracting unsustainable amounts from available freshwater sources.

One reason is that as the world’s population grows larger and richer, it uses more water. Another is climate change, which accelerates hydrologic cycles, making wet places wetter and dry places drier. The World Resources Institute found that 33 face extremely high water stress by 2040 (see map).

And as the global population rises from 7.4 bn to close to 10 bn by the middle of the century, it is estimated that agricultural production will have to rise by 60% to fill the world’s bellies. This will put water supplies under huge strain.

 In many countries people can pump as much water as they like from underground aquifers, because rules are either lax or not enforced. But it is unsustainable: around a fifth of the world’s aquifers are over-exploited.

People do not drink much water—only a few liters a day. But putting food on their tables requires floods of the stuff. Growing 1 lb of wheat takes 125 gallons of water; fattening a cow to produce the same weight of beef involves 12 times more. Overall, agriculture accounts for more than 70% of global freshwater withdrawals. Farmers in parched places grow thirsty cash crops such as avocados, which could easily be imported from somewhere wetter.

POLLUTION

In many places water demand is high and the quality is also at risk: as in many of the most stressed watersheds, it is often compromised by pollution. A polluted water source increases the risk of sickness not just of the environment but of the people and communities that depend on it for their survival.

THE HUG SPIN-OFFS

 HUG Applications

The  HUG uses the physics of the vortex to create a spiraling motion to accelerate the flow of fluid  in order to generate electricity or provide irrigation pumps from the water flow from tidal flows, waves, rivers, rapids, ocean and other fluid flows using a helical turbine and to transfer this fluid like water, oil or natural gas at near zero friction.

 

HUG Turbine
The HUG

There are many applications or spin-offs of the HUG, a new invention or a new good, which are named by their function:

  1. The Funnel HUG, used in ‘Run-of-River’ (Run-of-River HUG), and in a waterfall (Waterfall HUG) and the Reservoir HUG used to house an array of Funnel HUGs.
  2. The Pump HUG used in a river (River HUG), at a pylon (Pylon HUG), in an ocean current (Ocean Current HUG) and a tide (Tidal HUG)
  3. The Wave Energy HUG: creating electricity from wave energy
  4. The HUG pipe or HUG pipeline
  5. The Recycle HUG to recycle gray water
  6. The HUG Siphon for Waterfalls, Watermills and Dams

The “prior art” helical turbine is used to provide rotation to either the submersible pump or the electrical generator. One of the companies—GCK Technologies Inc. has a patented turbine using the helical blade.  Lucid Energy Technologies patented the same helical turbine in a pipeline, but there is no vortex claimed for either patents.  Continue reading THE HUG SPIN-OFFS

OCEAN WAVE ENERGY: WAVING GOOD BUY?

 

OCEAN WAVE ENERGY
OCEAN WAVE ENERGY

THE idea of extracting energy from an ocean wave and turning it into electricity is an alluring one. It has the potential to fill in the gaps that are left by wind and sun power plants when it is calm and dark.

 We calculate that the cost of producing electricity from the HUG will be around $0 .003 kilowatt hour. That compares with 16 cents a kilowatt hour for offshore wind farms, six cents for the onshore variety and a grid-connected fossil-fuel power station at five cents or more.

 HUG Wave Energy Systems are ultra-simple, only three moving parts: the helical turbine, the submersible pump and the electric generator (which is accessible and kept dry).  The simple HUG design will operate for decades with no more maintenance than an occasional scrub to remove accumulated barnacles.

The HUG uses higher waves to fill a higher reservoir to a greater water level than the surrounding ocean. The lower Pump HUG has a helical turbine, which engages a submersible pump in order to send water up a HUG pipeline to a second Funnel HUG above the water line on its own barge where its second helical turbine engages an electric generator in a dry environment.

The real advantage of the HUG is POWER from the action of the vortex in the HUG and the Venturi effect created by the shape of the HUG:

GREEN ENERGY

Green energy is the way of the future. Look at the Fossil Fuel and Renewable Energy Subsidies.

Coal, natural gas, and oil accounted for 87 percent of global primary energy consumption in 2012.

Our energy needs are growing to such an extent that we are forced to use whatever we have at our disposable without looking at the cost/damage. We are so dependent on conventional sources that the need to change often isn’t there.

Fossil fuel subsidies reached $90 billion in the OECD and over $500 billion globally in 2011. Renewable energy subsidies reached $88 billion in 2011. The IMF estimates that for 2015 the economic cost of energy subsidies worldwide will amount to US$5.3 trillion. This is not to be confused with actual amount of subsidies which are projected to amount to around US$333 billion for 2015. Without fossil fuel subsidies, the price of electricity by about 1.2 cents per kilowatt-hour. 

There is no such thing as clean coal, it’s a lie. If you think coal is great, why don’t you go live in Beijing and soak up some of that super clean air.

Hydroelectric energy This form uses the gravitational potential of elevated water that was lifted from the oceans by sunlight. At this time, most of the available locations for hydroelectric dams are already used in the developed world.  Hydroelectric  energy SUBSIDIES receive $0.01/ kWh.

Electricity: the Dominant Energy

Big Hydro’s Big Days are behind us

The $6.5-billion Romaine ” big hydro” development in Quebec, Canada will produce 1,550 MW: $4200/kW. British Columbia’s plan to build a new $8.8-billion hydro project on the Peace River for 1,100-megawatt: $8,000/kW. Manitoba may be in the worst shape of all: it has green-lighted the $6.5-billion, 700-megawatt Keeyask dam: $9286/kW (9 cents per kilowatt-hour).

The average cost of electricity from a hydro station larger than 10 megawatts use to be $1,000-$5,000/kW (3 to 5 U.S. cents per kilowatt-hour). The HUG$954/kW

There are additional indirect costs: damming interrupts the flow of rivers and can harm local ecosystems, and building large dams and reservoirs often involves displacing people and wildlife.

Cheap and abundant U.S. natural gas, with its lighter (than coal) carbon footprint, is eating Canadian hydro’s lunch. Export prices averaged 6.5 cents per kw/h in 2008. By 2012, that was down to 3.1 cents per kw/h – far below the production costs of any new hydro projects being built now.

By 2040, world energy demand is expected to dramatically increase (in 25 years)

Worldwide energy usage is on track to increase by roughly 40% in the next 20 years and to nearly double by 2050. Carbon emissions still have to be cut 84% by 2050, yet almost 70% of the kilowatt-hours of electricity consumed today comes from coal or natural gas. Electricity has to be the dominant energy form used in the future.
