Russia is number one in gas reserves. We do not realise how much wealth we have.

Gas generation is the cleanest; harmful emissions into the atmosphere are reduced to zero. By the way only one volcanic eruption in Iceland surpassed all thermal power station emissions in few years.

And "alternative energy" is:

- megatons of detergent chemicals to clean solar panels (SBs) in operation

-billions of tons of ore dug up in search of rare earth elements (REEs) and batteries for their production

-millions of birds killed by wind turbine blades (BGs) and vibration transmitted to the earth from the masts

- degraded landscape

-unstable generation for consumers and low efficiency of less than 10%, the remaining 90% of losses heat the already heated atmosphere (the efficiency of modern powerful gas turbine plant more than 95%)

No small-scale HV or SB will ever produce as much energy in its lifetime as was spent to produce it plus the metal-intensive masts, production and disposal of batteries and other "iron".

The conclusion is that "alternative" energy is fashion and politics.

 
Yuri Evseenkov:

.... low efficiency of less than 10%...

Don't lie.
 
We have plenty of firewood too (in case we run out of gas).
 

Russian scientists have created a cheap laser scalpel >>>

"Керамика – перспективный тип среды для лазеров. В производстве она дешевле и проще, чем монокристаллы, что крайне важно для массового внедрения. Кроме того, химический состав керамики легко менять, меняя и свойства лазера", — поясняет Иван Обронов из Московского физтеха в Долгопрудном, один из создателей лазера.

"The radiation from the most common infrared lasers has low absorption and penetrates very deeply into the biotissues, resulting in coagulation of blood and tissue, as well as significant areas of 'dead' tissue. A surgical scalpel has to work at a precise depth, so two-micron lasers are used which do not damage the underlying tissue," the scientist continues.

For this reason medics usually use holmium lasers for medical purposes, which are very expensive and not very user-friendly. The ceramic laser, according to Obronov, is devoid of all the disadvantages of its holmium cousins, and it is much more compact than traditional medical laser scalpels.

An added bonus of the Russian development is that the beam can be used not only to cut body tissues but also to cut through polymeric materials that are transparent to ordinary infrared lasers. The technology, he said, would find a place in the aircraft industry and other areas of industry where a lot of composite materials are used.

МОСКВА, 18 июл – РИА Новости. Ученые из Московского физтеха и институтов РАН разработали дешевый и мощный лазерный скальпель на базе керамических материалов, который поможет медикам вести операции без нанесения серьезных травм пациенту, а рабочим – легко резать и гравировать композитные материалы, сообщает пресс-служба МФТИ.

If they won't flap their ears, I will earn money on my invention. If they do, the Chinese will.
 
Alexandr Murzin:
We have plenty of firewood (in case we run out of gas).
And there is enough oil (we can keep warm with paraffin)
 
Alexandr Saprykin:
And there's still enough oil (paraffin to keep us warm).
You? Where does your oil come from? I don't have any.
