A Stirling Engine … for your motherboard?
Yup, a stirling engine that uses the heat from your mother boards CPU to cool it. All at a 70% efficiency.
This is a weird time for tech, and isn’t the tiny stirling engine cute? The article is here.

Cheap Hydrogen Production!
Well here we are again, cheap hydrogen, the holy grail of environmental energy storage. We have the way to use the stuff (fuel cells) and some ways to store it, but now we need to produce it from water.
The problem is it’s not too efficient to split water into the stuff (and oxygen of course). [...]

Finding Geothermal sites on the cheap by searching for Helium on the surface.
Geothermal is possibly one of the best natural power sources in the world. The geothermal resources of the USA alone in theory could provide 3000 times our current energy needs. The issue has never been using it, but it has been one of finding it cheaply. The technique so far has been to guess [...]

Trapping CO2 as Baking Soda.
Skyonic has a cool idea. The type of idea I like. Take some sodium hydroxide, add some heat, and you can trap co2 by changing it into sodium bicarbonate (Baking Soda) and release hydrogen. Now the CO2 is in a solid form and it’s useful. All you need is some heat.
Now put this at an [...]

Now Fluorescent bulbs are not good enough, here is a firm that seems to be making plug in LED bulb replacements for traditional Fluorescent bulbs. I guess it was a matter of time … cool though. I wonder if they flicker as well as Fluorescent bulbs. I’ll miss the flicker. More on it [here]

Free Hydrogen for EVERYONE!!!!
Free as in unattached, not free as in no cost.
So energy is pouring down on us in buckets, the problem is we have no good way to catch it. Batteries are not efficient enough, they loose energy over time. We need a good portable light weight and flow-able energy storage device. Something that does not [...]

Energy and the modern house renovation.
Let me introduce you to me and my project. I am GReg and I am in the processes of doing a massive renovation to a 1940’s house in north Florida. I am going to cover the energy saving issues I have tackled during this interesting trip through a lot of seemingly bogus information.
I am what [...]
