3 times even. The jackhammers that aren't toy models run off compressed air that has a 4 cylinder engine running it. 60hp perhaps.

Dear Prime Minister Trudeau and Minister McKenna;
Canada has a problem.
Climate Change is Killing Us.

Or more precisely, your view of climate change is killing us.
The first issue is to understand the words “climate change.” In the recent public discourse, “climate change” has come to mean “blaming humans for changing the climate by using oil and gas and coal.” That creates a major difficulty, because it means that anytime the uninformed see an aspect of climate that either they haven’t seen before or an aspect that is genuinely changed, the underlying assumption is that it must be our own fault and it must be change for the worse. This view of our climate as primarily anthropomorphic is useful for scaring the populace into submission so you can tax and regulate us to death, but in fact it is the modern-day equivalent of the geocentric view of the universe dating back to Ptolemy.
So, let’s be clear. There is no doubt that the climate is changing. The climate has always changed and always will. The climate will never stay the same – nor should it. The only thing more absurd than denying climate change is thinking that humans can stop it from changing. But when people today say the words “climate change” they mean something else. They mean that humans are to blame.

It is only natural that because we humans tend to incorrectly perceive ourselves as the centre of things we would tend to blame ourselves when the earth’s climate changes. This flaw in human thought is not new.
The Maya, Inca and Aztecs used to do the same thing. In a vain attempt to control the weather and the resulting crop yields, they would engage in human sacrifices including decapitation, blood offerings and live heart extractions. If those efforts didn’t work and the crops failed, then the assumption would be that they didn’t do enough of it – leading to more sacrifices. Today it seems obvious to almost all of us that blood offerings don’t change the weather. I find it strange though that when the sacrificial offerings are from our own treasury, especially if the victims of sacrifice are either corporations or wealthy individuals, you and many other Canadians continue to believe essentially the same thing. And what leaders know is that being the master of the sacrifice concentrates power in those conducting the ritual.

Your government’s view that Canada can stop the global climate from changing by taxing Canadians, killing billions of dollars of new projects and chasing foreign investment away when none of the major global powers are doing the same is profoundly harmful and irresponsible. You have created a graveyard of cancelled mega-projects that are severely damaging to Canada but that strongly benefit other nations for no good reason. The Energy East cancellation resulting from the NEB including ‘climate change’ considerations in its evaluation of that project is the latest serious casualty. Insanity! You should be ashamed that we will now unnecessarily import oil from dictatorships when we could be building a stronger Canada.
Just 18,000 years ago almost all of Canada sat under giant thick sheets of ice. Both the Cordilleran and Laurentide Ice Sheets were continuous sheets thousands of kilometres across and several kilometres thick. They melted entirely without human intervention (as did their equivalents in Asia and Europe). They melted so quickly that the rocks upon which they rested (including the Canadian Precambrian Shield) are still rebounding from the rapid removal of their incredible weight. Sea levels have risen over 100 metres during that period separating Alaska from Russia and modifying ocean currents around the globe. The changes we are observing and living through at present are simply the tail end of that monumental transformation and are absolutely in keeping with natural climate change.

Imagine the energy required to melt several continental ice sheets thousands of kilometres across and several kilometres thick, thereby raising the sea level by over 100 metres in just a few thousand years – a blink of an eye in geological time just on the edge of recorded human history. Let the fact that humans had nothing to do with that sink in, and then ask yourself how taxing Canadians and issuing government subsidies to install windmills and solar panels will stop that sort of planetary-scale climate change.
Rather than the disaster that you would have us believe has befallen us or will befall us in future, what we have in fact observed is that access to abundant and reliable energy has increased human life spans, reduced famine and suffering and lead to unprecedented levels of prosperity around the globe. Access to secure sources of energy reduces the impact of climate to humans, not the other way around.

Today, humans are more able to respond to natural disasters than ever before largely because we have access to abundant energy – and this is a good thing. Life before hydrocarbon energy was available was much harder and many lives were cut short by starvation and disease. Today, anti-hydrocarbon positions are written with computers made of and powered by hydrocarbons by people who got to work in a vehicle powered by hydrocarbons, who demand access to health care that is only possible because of hydrocarbon energy and who go on vacations to warmer climates in planes powered by hydrocarbons. The hypocrisy is telling – no opponent of hydrocarbon energy seems prepared or willing to live without it – including you and your government.

It is noteworthy that the two primary products of hydrocarbon combustion are H2O and CO2, which (along with the sun and nutrients from the earth) also happen to be the very building blocks of life on earth. This is because hydrocarbons are themselves the natural product of organic growth and decay. The primary indisputable and measurable impact of increased levels of CO2 on earth is that plants will grow quicker – which is why greenhouses routinely pump CO2 into their greenhouses (to levels 300% higher than current atmospheric levels) to accelerate plant growth. CO2 should be celebrated just as water is, not vilified as a ‘pollutant’ – which it clearly is not.

There is no invisible thermometer controlled by taxation and regulation and subsidy that will change the output of the sun or our relationship with the sun. It turns out that the earth and the sun and the universe at large just don’t care that much about humans or our actions. The simple fact of the matter is that we are vastly more affected by the planet than the planet is by us – and one day in the distant future we will simply be another sedimentary layer in the geological record.
However, just as Galileo was persecuted during his time for advancing a heliocentric theory and questioning the geocentric view of the universe, those of us who question this anthropocentric view of climate are now also subject to ridicule and persecution.

This persecution takes shape in the notion that if I deploy scientific knowledge to refute many of the alarmist claims made by those who believe climate change is anthropogenic, then I must be a ‘denier’ – an epithet closely linked to neo-Nazism that would subtly try to link me to that horrible way of thinking.
Statements like “the science is settled” or “97% of scientists agree” are extremely troubling as they are themselves anti-scientific and designed to suppress the relentless questioning that is essential to the scientific method. Even Neil DeGrasse Tyson’s statement that “the good thing about science is that it’s true whether or not you believe in it” misappropriates the scientific method to declare science as an infallible source of truth rather than a process of finding and discovering truth through questioning and testing. People in your government tend to say things like “Canadians know…” or “We all know…” when it comes to the anthropocentric view of climate change. In fact, we may not know, or we may know the opposite.
Instead, I prefer Albert Einstein’s statement that “The important thing is to never stop questioning” as the ultimate piece of scientific advice.

The anthropocentric view of climate change has confused the masses and under your leadership is causing Canada to make a series of terrible decisions. In subscribing to this ill-conceived view of hydrocarbon energy as a bad thing, Canadians are suffering terrible casualties to your Liberal government’s economic friendly fire.
I have no doubt that you believe you are doing the right thing and that your intentions are good. The road to hell is paved with good intentions and history is full of leaders who destroyed their nations in fits of madness and in pursuit of vanity and folly.

It is high time you considered that you might be wrong. Many of us can already see that you are.

Best Regards,
Allan Châtenay

Will be interested to see the size of the battery required to operate a jack hammer for more than a few minutes



Real jack hammers are air powered. I don't see electric replacing air in certain uses - like painting. Unless a battery powered compressser...

There have been electric jackhammers for at least 20 yers. Also hydraulic.
The problem with battery tools is that they invariably go dead at the least opportune time. Last weekend we played with battery powered Auto EX tools. These are the same basic jaws and cutters as the traditional hydraulic tool but with a battery powered pump built in. Abit heavy but have their application. Catch is they use smart batteries that cost somewhere around $600 each. And the bastards would die half way through a cut.

in a year or two those batteries will be replaced by batteries that are many times more powerful and longer lasting and quicker charging.

Mercedes sells their E vehicles with free upgrade for batteries as they become available.

As was pointed-out, that air compressor will need to be powered (and a significant amount).

.... Or are you suggesting that compressors be exempted from the green energy revolution

Kind of.. I drive with 427 horses and an updated buggy.

No whip required (for the horses that is)

Tesla Model S has 779 horsepower with 920 ft lbs of torque delivered through a one speed transmission. Far superior to any gas engine ever made.

I've seen electric motors in operation in vehicles and it is damned impressive.

That said, my questions are not about performance (horse power wise) but relates to range, load and big questions about cold temperatures affecting the batteries.

In the end, it's not a question of IF hydrocarbons will be phased-out, but when (based on the notion that the storage/transportation of electricity is too undeveloped to achieve these goals in the near future)

The near future? They are already superior. IN the near future they will be even more superior. In the not too distant future they will be obsolete, rendered so by the next scientific break through.

The computer has altered every time line.

If you ever drove tow motors, you know electric engines do just fine.
The problem is batteries

This is what is at the core of the issue... Add to that power consumption/battery drainage on inclines and ambient temps (cold specifically) on the battery life capacity.

Have asked that (and other) questions repeatedly, but the issue(s) go unanswered as the only response undermines the practicality of the tech as it stands today

Battery technology has progressed tremendously.

It will continue to do so.

I think it's essential to put internal-combustion engine powered generators on all our satellites.

Seeing as how solar panels are useless and all.
