Investments are tricky things, especially startups and the super-risky types of investments. You know that if you pick the right ones, profits would be HUGE. Conversely, if you pick the wrong ones, well, losses would hurt. If you want to take some chances, but still be ensured of a profit margin, check out these four, more unusual investments for your portfolio.

​Gas Project Investment Opportunities

​Gas project investment opportunities involve backing companies looking for natural gas, backing companies that drill for and extract natural gas, and supporting gas companies that sell gas to consumers for heating and industrial purposes. In any of the above, you can expect a profit because natural gas is a commodity that many people need for residential, commercial, and industrial purposes. Since it is also a clean-burning fuel, many people are making the conversion to gas from other natural fuels or electricity, which ups the demand and ups the profits.

​Gold and Silver

​Gold and silver investments involves either buying coins and bullion of the metals, or buying shares in existing caches of the metals. Either option works, but the shares are a little safer because only you can cash out the shares when you are ready to do so. If your paper shares are ever stolen, they cannot be sold or traded or cashed without a photo ID and another form of picture identification. The shares act as a fraction of a single bullion bar of gold or silver, so the more shares you purchase, the more money you can make when you are ready to liquidate the shares.

Pork

Yes, it is funny, seeing how "pork" is typically a word used by investors to mean something of not very good value, or something that is just a filler. Yet, pork, as in the pig meat, is a real investment. Pork farms are struggling in recent years, and to stay afloat, they have begun looking for private and public investors to help them remain running and promote pork as a good protein. If you are fond of bacon, ham, BBQ ribs, and pork chops, consider investing in the pork production industry. 

Solar Energy

It is interesting to think about investing in something you cannot really see or touch; only feel on a warm summer's day. However, solar energy, the conversion of solar light and heat to functional energy, is definitely winning the energy wars for the future. Continued advancements in solar technology are supported by investors, like you. One day, the sun will power nearly everything, and those who get in on the ground floor now may find themselves quite warm and cozy (financially speaking!) down the road.
