We're not out of energy: we're just exploiting the existing non-renewable resources in Renewable energy

Posted on Apr 15 2009 at 04:19PM by prajwal

The energy crisis that is almost sure to be faced in the near future as well as the shortage of energy at present is not actually because we're going out of energy.It's just because we're using the same resource day by day and second after second without acknowledging an alternative (or minimal use). We still have our sun, we have wind and we also have plenty of water.The only thing is that they're not being utilized upto their true potential due to many reasons. But if all that potential of these perpetual sources are brought to use, we can be sure of getting enough energy. Also the earth can be made greener and cleaner if these three sources compltely replace the other energy sources like fossils and nuclear reactions used in our daily lives.

Isn't this a good alternative too.... in Renewable energy

Posted on Apr 20 2009 at 01:51PM by prajwal

I recently got to know from a news that scientists found a way to convert carbondioxide gas into methanol. Methanol is a far better fuel (in terms of the adverse effects that fuels leave behind) than other fossil fuels. Many vehicles have also been developed  that run on alcohol. Infact, we can capture the carbondioxide gas that is released from the combustion in the engine (instead of releasing it through the exhaust) and convert that CO2 into methanol within the vehicle and send it to the fuel tank. This way the same fuel can be used again and again with higher efficiency, higher mileage per litre and lower emission to the environment. On the other hand, the water vapour that is released along with CO2 during the combustion could be filtered too and be used for otehr purposes like cooling the engne itself after condensation.:)

Yes, I agree with Nadine McCormick. Storage of enrgy within large scale batteries is a wiser use of electricity produced at night.

It's still a problem though... in Renewable energy

Posted on Apr 20 2009 at 02:02PM by prajwal

Burning CH4 ie. methane anly releases CO2 and H2O. But these two components are also among the major reasons of global warming Thus, methane as a fuel might release less toxic substances to the atmosphere, but still it can accelerate global warming aka greenhouse effect.

that's ok .... in Renewable energy

Posted on Apr 20 2009 at 02:49PM by prajwal

That's ok. But drops make an ocean. Yes, toxics are far more toxic or say, unfriendly to environment and living beings than CO2, but global awrming is also an already emerging problem. It's a better way to transit to methane from gasoline and other petroleum,and you're right there, but for long term term usage, we can't deny that even methane can put forward a hazard too. At present methane as well as LPGs are a good alternative to gasoline and diesel, but in the future that must be be alternated too.

:) in Renewable energy

Posted on Apr 20 2009 at 03:07PM by prajwal

I don't know much about the transformation that was discovered by scientists from IBN (Institute of Bio-engineering and Nanotechnology) .But, it's a chemical reaction that can be carried under mild conditions and dry air with the help of NHCs ( N-Heterocyclic Carbenes), which is a stable and non-toxic organocatalyst. IMes, whose molecular formula is 1,3-bi-(2,4,6-trimethylhenyl)imidazolylidene, is an NHC which is stable, doesn't contain heavy toxic metals and can be easily produced and stored withou high costs.
This is a recent discovery.Thus it might take some time for this to come to practice.But,when it does, I think it mgiht bring a new breeze.
This could also be used to capture excess CO2 from the atmosphere and convert it into useful fuel, like methanol.

yes.... in Renewable energy

Posted on Apr 21 2009 at 02:43AM by prajwal

But the news reads that the reaction can be performed in mild conditions in dry air.Doesn't that mean the reaction needs very less or no external energy? If so, may be a battery, or the engine itself can be used to generate energy for that.Yes you can have a pdf document on that here....

Storing energy in Renewable energy

Posted on May 13 2009 at 12:57AM by prajwal

Yesterday I  watched a show on the Discovery channel about the Tower Bridge in London. It uses steam engine to lift  the two halves of the bridge. The interesting thing is that it uses the power generated is used to lift very heavy boulders of steel to a certain height and produce potential energy in them.This potential energy is then again used to lift the bridge easily and quickly,with the help of hydraulics.It's a very good idea,isn't it?
We can use a number of these steel boulders to store excess energy produced at night and then use the potential energy stored in these boulders along with hydraulics to drive a generator to produce electricity in peak hours.

We should update our lives... in Species - The extinction crisis

Posted on Jul 08 2009 at 05:22PM by prajwal

Our modern daily life directly or indirectly is affecting other species.We buy more packaging than the items we actually need, we bring home a plastic bag for each product we buy,we leave behind tons of carbon footprint for each mile we move...There are a lot of things we repeat that adversely affects the environment,this effect to the environment is transferred to the species living here.Pollution,overpopulation,global warming...all are our gifts to the nature that supports species' extinction. To worsen this, there are only a few efforts from personal,communal,social,national and international level.

Need to save them in Species - The extinction crisis

Posted on Jul 08 2009 at 05:35PM by prajwal

Our country,Nepal, is one of the few habitats of many endangered species like one-horned rhinos.Many times, we've come to hear about poaching, dead rhinos, but we never get to hear about poachers. Some weeks ago, poachers cut of the horn of a rhino and left it in the reserve.It died of infection,waiting to get treated. A week or two after that, another rhino was found which was shot with a bullet. It too could not be treated because of lack of essential equipments, and died. But the officials were happy that they the horn was not stolen. Hey the rhinos gone and they're glad the horn was there!!!(Does this mean you'll kill all of them yourself and save the horns in a museum?) There are many such cases. Get up government and non-government,they're vanishing one by one and their present number could be counted on fingers.

yes... in Species - The extinction crisis

Posted on Jul 13 2009 at 03:57AM by prajwal

The best way of eradicating the solid waste disposal problem is lowering the production of such wastage, giving priority to bio-degradable items like papers,clothes and fabrics and easily recyclable materials like glass over plastics. Reusing and recycling solid waste can reduce this problem, but to reduce this in a large extent, use of degradables and easily recyclables must be promoted.

Don't try to interfere with the ecosystem.... in Species - The extinction crisis

Posted on Jul 20 2009 at 10:24AM by prajwal

A whole stack of bricks collapses when one brick falls. In the same way even a tiny insect killed in artificial manner can have a great impact on whole ecosystem. The use of chemical insecticides and pesticides not just kills insects in our crops,it kills the food of larger insects and small animals and birds. This eating and being eaten continues to humans as well. Then why not live the killing to other species insect of using chemicals. This kills the insect as well as holds the ecosystem.For this I think it's a good idea to protect the larger and friendly insects in order to kill the smaller insects that harm our crops, instead of using insecticides which kills those friendly insects as well. And note that insecticides also harm our crops,which are a part of ecosystem as well as our food.

What about breeding... in Species - The extinction crisis

Posted on Jul 20 2009 at 10:33AM by prajwal

Breeding endangered species,if possible, can prevent their extinction. But in the Koshi Tappu Reserve in Nepal, breeding has created another problem. It's the breeding between domestic buffaloes and wild water buffaloes (arnas) that is supporting the decrease in water buffalo population and increase in the number of cross species.

That's true.. in Species - The extinction crisis

Posted on Jul 20 2009 at 11:04AM by prajwal

If we buy,we kill. Poaching can only be controlled by stopping to buy anything that's,in any way,related to endangered species. If we stop to buy rhino horns or elephant ivories or tiger parts or whale meat or fur from species on their way to extinction, what could the poachers possibly do with their kill. And next time they'd probably stop the kill.

We don't need to import predators... in Species - The extinction crisis

Posted on Jul 24 2009 at 03:23AM by prajwal

Yes, importing predators from other places can be a havoc. But who
needs to bring them from other places. They're locally available. And
every locality has its own complete eco-system. And we can,for sure
leave the killing to a local predator,instead of using pesticides which
kills them both, bringing imbalance to the eco-system and creating a
probability of their extinction which can induce extinction of other
higher members of the eco-system.

Posted on Jul 24 2009 at 03:31AM by prajwal

I am 19, but I still like spongebob squarepants. Cartoons are liked by all age groups. So,delivering a good message for protection of a species by turning him into a cute cartoon characters, can for sure turn out to be a good campaign. These can include endangered species like one horned rhinos in Nepal and India, water buffaloes, whales,sharks, red pandas, crocs and alligators, buck deers, monitor lizards, corals, bengal tigers, asian lions and many others that I don't know the names of. This also helps in inducing a mentality of conservation of species in a child, which is humans best learning period.

It's true,but.... in Species - The extinction crisis

Posted on Jul 31 2009 at 04:41PM by prajwal

Yes. It's true that's there's a lot of things to do to protect the environment and species apart from planting trees. But it would be a good start. So many things are depended upon those woods. Just planting woods doesn't solve all the problems, but it surely does solve many problems. It's very true that we can't stop poaching, black marketing of animal parts, controlling our rate of use of materials, decrease the production of waste, etc. And these needs some other measures. But why not start with a tree?

One good step...at least.. in Species - The extinction crisis

Posted on Aug 09 2009 at 04:08AM by prajwal

The central Zoo in Kathmandu, Nepal has brought out new rules for regulating plastics. They've banned the visitors to take plastic bags within the premises. This is a good beginning as few deers were dead in the zoo due to choking plastic bags. Instead of plastic bags,they're renting or selling cloth bags and bamboo baskets. But to make this more effective, they'll have to ban plastic bottles and cans as well. However, they've done a good job.

Climate change... in Evidence of climate change and ideas

Posted on Sep 01 2009 at 02:19AM by prajwal

Congratulations Connect2earth and all the active participants for the success of previous discussion.
Climate change is one of the most growing problems. As we all the the main cause of this is global warming, caused by carbon dioxide gas released by us to the atmosphere. This carbondioxide forms a natural greenhouse in the lower part of atmosphere trapping heat radiated by our earth. As heat can't escape, it increases the temperature of the earth gradually, resulting global warming. So if we could find a way to scrub the excess carbon dioxide from the lower atmosphere, a large chunk of the problem can be neutralized. Also further production of carbondioxide must be decreased and afforestatiom must be encouraged.

Ways to scrub carbondioxide from atmosphere.... in Evidence of climate change and ideas

Posted on Sep 01 2009 at 02:26AM by prajwal

There are different tests going on to find out a way to scrub carbondioxide from our atmosphere. One of them I came to know about is by freezing the gas into dry ice and then submerging it to ocean floor. Then the temperature and pressure at the bottom of the ocean keeps it from sublimating. It seems like a good idea. But who knows if this couldn't raise another problem to the species on ocean floor.Does anyone know about this? Please reply.

Yes I agree with you.... in Evidence of climate change and ideas

Posted on Sep 02 2009 at 12:59AM by prajwal

Yes,I agree that it requires energy. But if the amount of carbondioxide absorbed and frozen could be at least twice that of CO2 released due to that energy, it could be considered.
However, yes we know very little about the deep sea eco-system and we're not sure if it creates a havoc there. So deep research must be conducted before trying this.

That's right... in Evidence of climate change and ideas

Posted on Sep 02 2009 at 01:22PM by prajwal

Yes that applies for many othe places on earth as well. Here in Kathmandu, which is considered as a cool place, has been turning into an oven. This year, I felt the hottest summer. i'm afraid of next summer and the one that follows. The monsoon here arrived a month late, affecting our paddy farming and postponing it to a year later, in our country where 80% population depend on agriculture. The winter is near, and I wonder how it would be. Climate change is affecting everything. On one hand drought has affected agriculture raising price of food products and even causing shortages which makes it very difficult for poorer families to feed themselves. On the other hand, the heavy rainfalls ,supported by deforestation, is causing floods and landslides affecting thousands of families.
Climate change must be stopped from taking it's most frightening shape.And it must be begun from our doorsteps.

Bio-fuel.....a better alternative... in Evidence of climate change and ideas

Posted on Oct 27 2009 at 03:39PM by prajwal

In our village, once, there had been a campaign for construction of a bio-gas plant in each house that own either a cow or buffalo or both. It's still in use there. It has may benifits. One it uses the wastage from cattles as well as humans to produce gas for cooking,which has very low carbon emission.This reduces the use of other sources that could pollute the air. Second, it prevents the human wastage from being transported to the sewer and then the river,which reduces water pollution caused by sewages. Third, the solid and liquid waste that is produced by the plant is a very good fertilizer, which reduces the use of chemical fertilizers hence reducing pollution. Hence, use of this kind of bio-gas plant helps manage waste as well as reduce pollution, primarily air pollution, which is the major cause of climate change.

Hey Binay,
You're right. The increasing number of small vehicles and less use of buses in one of the main reasons behind this. The trolly buses, which were a popular mode of transport in Kathmandu, are now trashed. And the old vehicles that should be trashed are runnung. The government has time to wed the trolly buses and wait for them to have children, but they don't have time to bring it to life. Binay, the voice must be raised for this. The trollies must come back to streets. We can at least shout.
