John1940's recent activity

  • You are right, as usual. It's all too easy to forget or simply not realize it. Until 1950 all the CPR trains that went across Ontario east/west were pulled by coal-powered steam engines. They ...
  • You may have to tolerate nuclear power on a massive scale all over the world. It is the only known way to meet our future demand for electricity while not emitting any greenhouse gases. It is a ...
  • I'm 75 years old and I'm more up to date in this field than you. BTW, do you support nuclear power? John1940
  • One of my friends down the road set up a nice solar system 15 years ago. It has several large panels on a separate structure aimed due south. He is able to vary the tilt the angle of all the ...
  • Don't get rude by telling me not to get in the way. If there is a breakthrough in large-scale storage of electrical energy, then wind and solar power will really take off. If it's a no-brainer to ...
  • It is quite the opposite of a no brainer. After 100 years of research, we still cannot store electrical energy on a large scale. See all my posts in the following: http://www.dpreview.com/forums/po ...
  • such as wind and solar power? I'm all for that but it requires some way to store electrical energy either on a grand scale or in every home. Let's increase the funding by a factor of 50 to start. ...
  • Nothing significant will happen by saying that because we cannot even measure improvements of doing more than we already are. Since we moved to where we live 29 years ago, the biggest improvement ...
  • Solar is a great energy source but it's like being in the desert and suddenly getting 10 liters of water from some source but only having a 1-liter container to hold it. You cannot drink the other ...
  • Replied in Sunny side up
    Stunning photos! John1940
  • I would never say that nuclear power plants are 100% safe. But did you know how many people died from the worst power plant failure of what one would consider to be safer, a hydroelectric power ...
  • Replied in Should vs will
    I agree. John1940
  • So do I, but I'm afraid I am correct. Unless there is an unforeseen breakthrough in storage of electrical energy on a large scale, wind and solar are minor energy contributors. Or study and learn ...
  • I agree that greenhouse gas emissions are the major problem but, if you read my first post, wind and solar power cannot be a solution because even after 100 years of research we still cannot store ...
  • If if we suddenly only used the known oil reserves in the ground and under the sea bed we would run out of oil totally in 1653/32.1 or approximately 50 years . Increasing research money ten-fold ...
  • Hello hydraulic fracking, low cost petroleum, natural gas and CO2; goodbye nuclear, solar and wind power growth. It seems to be a fact that we are not yet near the tipping point with regard to CO2 ...
  • That's actually a good and viable idea. By doing that, the CO2 emissions would be reduced to the same level over all as those of traditional oil wells. However, with the low current price of crude ...
  • Yes, 4x4. With the blower on the front, it is pretty well useless if I leave it in 2WD. I still have a 50 HP International 2WD tractor and had a 7-foot snow blower in the back, and sold it. For ...
  • It feels like -40 F (or -40 C). Just another day in paradise. I lasted about an hour. First the hands get really cold. Then the toes. Then hypothermia sets in unless you go inside to thaw out. ...
  • Which is when?
