Imagine what this would've meant to people during and after Hurricane Sandy who were left without heat or power?

As it happens, CEO Jonathan Cedar and Chairman John Levy told Cramer, they did go around Brooklyn, N.Y., where the company is based, and other affected areas to help people charge their cellphones and leave them some of the stoves.

"This is personal-scale energy access," Cedar said.

The stove, which can heat a cup of tea in four minutes, is also being tested in third-world nations where there isn't a lot of access to power -- but everyone has a cellphone.

Right now the stove, costing, $130, is only available through the company's Web site, BioLitestove.com, but next year it will be available in wholesale locations.

Unlocking DST's Value

When it comes to DST Systems ( DST), an information processing and software services company, there are many ways it could unlock value, Cramer said.

It could be an acquisition target, or it could split itself in two, he pointed out.

So far, the company parts are worth more than its whole and it's been selling off non-core assets. The company looks like it's preparing itself for a sale, Cramer said. If it catches a buyer DST could be worth $75 a share.

Cramer reminded viewers that he does not recommend buying a stock based on its takeover value but must be worth something on its earnings.

"Even if DST doesn't get bought out, it has a fabulous story," Cramer concluded.

Lightning Round

In the Lightning Round, Cramer was bullish on PDC Energy ( PDCE), UnitedHealthcare ( UNH), Merrimack Pharmaceuticals ( MACK), Cabela's ( CAB) and American Capital Agency ( AGNC).

Cramer was bearish on Finistar ( FNSR) and Hovnanian ( HOV).

Mad Mail

Doing his homework as a follow-up to some earlier questions, Cramer said Micros Systems ( MCRS) is very cheap and its valuation is attractive. He suggests starting a position here on weakness. It's a nice entry point, buy, but keep an eye peeled for lower prices.

Xylem ( XYL), the company that pumped 12 feet of water out of the Brooklyn Battery tunnel after Hurricane Sandy, is an exciting pure-play water company. Its stock isn't doing so well because of weakness in Europe. Cramer suggests waiting for a pullback to $24 before buying.
