batteries the energy game changer

[conradelektro]

How I see the energy future:

What we need is a non toxic battery which lasts a long time (million time charging/ discharging, mechanically sturdy) and with a reasonable capacity.

The rest is energy saving. We have to get used to the idea that energy will be expensive and that every individual has to use less. The rich will have much more energy than the poor.

Energy saving which will happen:

- the LED light follows people around the house or office, and is switched off else where
- the refrigerator has to become a lot smaller
- no deep freezer (canned and dried food instead)
- much less travel by car, more public transport (only the rich can drive cars every day)
- only the living room is heated during the waking hours in winter and to a lower temperature (better clothes have to be worn, better insulation of houses)
- no air conditioning in summer (better natural ventilation and shading)
- the gadgets (e.g. mobile phone which is everything also TV and recording device) use less energy and are charged by alternative power sources like solar and vibration (from your movements)
- the power grid has at least a loss of 50% (resistance of the wires and inductive losses), therefore the electricity has to be generated near the place where it is used

Of course, the rich (about 2% of world population) will have enough energy but most of the people will have very little from batteries and crude devices (like pedal power).

You will enjoy a smart phone (which uses very little energy which you provide at your home from a small solar cell, small wind generator, pedal power device) in a rather dark and cold/hot and very small house or flat. You will commute in a crappy public transport where it is dangerous (mugging by your fellow citizens). Go to big cities in the Third World to experience this life style right now. May be New York, Paris and London can provide that way of life largely today.

Welcome to the future,

Conrad

We have to differ : on/off grid battery systems


On grid I prefer the iron-air battery solution,cheap and abundant materials !
For home use weight (50Wh/kg)will not make any trouble !


Off-grid there are actually some different solutions and what we know is that for 2020 the KWH-costs from these lithium/magnesium/aluminium/zinc....cells will fall
under the 200US$-limit (McKinsey-study/outlook)


And yes,
@ conrad is allright
freezer as refrigerator http://mtbest.net/chest_fridge_1.pdf
LEDs
warmwater by friction or heat pump
room heating with efficient heat systems
kitchen appliances with energy saving heat conductors and efficient VSD-motors
