Desk-Size Turbine Could Power a Town

Desk-Size Turbine Could Power a Town

GE Global Research is testing a desk-size turbine that could power a small town of about 10,000 homes. The unit is driven by “supercritical carbon dioxide,” which is in a state that at very high pressure and up to 700 °C exists as neither a liquid nor a gas. After the carbon dioxide passes through the turbine, it’s cooled and then repressurized before returning for another pass.

The unit’s compact size and ability to turn on and off rapidly could make it useful in grid storage. It’s about one-tenth the size of a steam turbine of comparable output, and has the potential to be 50 percent efficient at turning heat into electricity …

Power For Your Oxygen Concentrator

Power For Your Oxygen Concentrator

Unless you really rely on medical devices, you may not understand how vital for your survival some of them are. Especially, if you don’t have any major respiration issues, or they’re largely under control, you’ll not give a lot of thought at all to oxygen concentrators.

Until you need them… That’s the moment you understand you must have read and learned a lot of about them. Including how to provide power to them in case of a serious emergency in which typical electricity may not be available for days or longer. That’s the article you need to read to get this knowledge!

How much power do concentrators take?

The amount of electricity required for each unit depends mostly on the size of the compressor and the manufacturer ratings. In most cases, the devices will run on batteries, but there’s also considerable variance on how efficient the unit is and how much oxygen it will actually produce.

As a general guide, older, home oxygen concentrator units required about as much electricity as refrigerator. Trendy devices may take as little as a low wattage microwave, while others may still require quite a bit more.

There some things to be aware of before buying a concentrator for survival needs, and here are some of them:

  • Amperage required by the device
  • Voltage output from the emergency battery pack
  • How long the concentrator will run on the battery pack at different oxygen output amounts
  • How long the batteries are expected to last and what they are made from

 How many batteries you need to buy?

When it comes to buying batteries, most people will buy one for charging and another for using any given device, but this is not always the simplest route to take, because not having enough batteries for charging and powering will spell disaster.

Buying a lot of batteries than needed can take up excess space and also create a situation where rechargeable batteries aren’t used at best loads and rotations. At the very least, …

Flashlight Power

Flashlight Power

Flashlight technology has return a long approach since 1899 when British inventor David Misell obtained a U.S. Patent for an “electric device” using newly-invented “D-size dry cell” batteries. When he introduced the hand held light he initiated a revolution in lighting. Since then, flashlight design has created exceptional progress. Each light bulb and battery technology improved significantly, and the trend is continuing.

The Basics of Flashlights

The flashlight uses batteries that contain stored DC energy. Connecting many batteries together (in series) with a conductive metal strip, an on-off switch, and a bulb creates a flashlight. When the on-off switch or button on the flashlight is closed the circuit is complete and the bulb lights. Add a lot of batteries and a different bulb and you can realize an even brighter flashlight. The flashlight can be left energized providing continuous light till the batteries discharge. Then the light bulb goes out and you need to install new batteries to get the light back on.

A flashlight creates a beam of light that illuminates objects close or distant depending on the power and shape of the light beam. Because the distance from the flashlight increases, …

Prepper Guide – Power Outage and Lights out Kit

Prepper Guide - Power Outage and Lights out Kit

Lets face it, we are completely dependent on electricity. Everything we do in one way or another was created because of electricity. As preppers we are concerned regarding many alternative disasters, and the possibility of being without power goes along with several of them.

It doesn’t need to be an EMP strike or a terrorist attack that takes the grid down, we may lose power at any time as a result of weather or natural disasters. If you’re like me when the facility goes out everything you’re doing stops. If you’re lucky, it happens during the day and everything goes silent. If it happens at night that’s a whole completely different ball game.

Along with having food and water, having a lights out kit and alternative energy choices are at the top of the list for preppers. Not only will the lights be out, but your ability to cook, stay heat or cool or use the toilet can and will all be affected.

Every year within the fall I do a detailed inventory of my prepping provides, check expiration’s and ensure everything is in working order. So, I figured while I had my lights out kit and provides out.

The Lights Out Kit

I call this my lights out kit, however it’s really more of a place that I put the supplies I don’t need touched, and I don’t want anyone to dig through on a day to day.

It’s not everything you’ve got or need. There are most likely lots of provides that you have that won’t fit in a plastic tote, and there are plenty of provides that are scattered around the house that you use frequently. We have items like candles, lighters, flashlights and solar chargers that we use regularly that don’t go in this kit.

It’s not for fuel or lamp oils. You don’t want to store kerosene or lamp oil in the same container with your other supplies, and if you store it in the garage you wish to make sure everything in it can handle the intense temperature changes more on this later.

It’s for stuff that you don’t want touched. The children are notorious for taking batteries or mixing up dead batteries with new batteries, so I like to have a stash set up that I know for a fact that I have the supplies that I believe I have.

It’s for stuff you won’t use frequently. Like the saying goes, 1 is none, and 2 is 1 …
