- Renewable resources seem to be the smartest way to solve our decreasing current resources, so why is it that we are not working harder to produce more windmills, water turbines, or use of the suns energy? And where would I find research on the advancements of these projects?(2 votes)
- It is because currently fossil fuels are cheaper and easier to use. It is also very expensive to store electricity and due to the wind not always blowing and sun not always shining, you have to store this electricity so when you are not getting any electricity you have extra in reserve.(4 votes)
- What is the device pictured at1:32? It appears to be some type of sensor that attaches to a power line(1 vote)
- Hello JC,
It looks like that are performing a laboratory calibration of a new sensor. The power line wire is heating up due to the high current flow. This link may help:

- IBM launched the "Battery 500 Project" in 2009. There are many web sites describing it. In 2012 all discussion about it stopped. I suspect the military took control and it wont be available for consumer use in the near future. Has anyone heard anything about it recently?(0 votes)
