Multimeter not working, HELP!?

We Answered:

It is probably the fuses in the multimeter. There should be two.

If you have a second multimeter you can use, check the continuity of the fuses after taking them out. Otherwise, just replace them with new ones.

I want to go solar... all electric or keep gas?

We Answered:

I can see advantages to both options. It all depends on your intentions for going solar. Is your motivation environmental, independent living, or emergency preparedness? Do you intend to keep your utility connection and supplement it as much as possible with solar, or do you wish to be utility independent? If you keep the utility connection, then go all electric, and buy some Eden-Pure heaters for your heating needs. You will feed the grid all summer long, build up a big credit, and use the excess to run the heaters in the winter. If Independence is your goal, gas makes a good back-up plan in the event your solar does not generate a sufficient amount of power. When you say "gas" are you talking kerosene, LPG (propane) or natural gas? If you want to prepared for all emergencies, and LPG is available in your area, use it. Buy a tank big enough for a year's supply.

Be careful of tankless water heaters--gas or electric. Many do not support preheated water conditions, and will cause problems on a solar water heated system. Your bills are quite low, you are likely very energy conscious already. Solar will be a great fit for you regardless of which way you go.

if and how could i make money on this?

We Answered:

You need to do a patent search,and assuming no one has already invented this, make your patent

First and foremost: Document your invention. There is a process, and it would take paragraphs to describe it, so google it.


edit)) and remember, you will have to invest money in your invention to make money from it. It is unreasonable to think you won't have to put some money up front to get attention.
In business school they teach us that risk and reward are directly proportional.

Heat sink fan project?

We Answered:

Yes, they will cool it down rather fast. But, remember you want to save power so you will need a thermostat and wire it in so they will shut off and start up when needed.

Ryobi makes a great unit that runs on an 18v battery. It has 2 speeds, is highly reliable, and can take a real beating. You can easily solder in a home unit, through the battery pack terminals, to accomplish exactly what you are looking for.
