Maurice Mountain is a retired lawyer in Washington, D. C He developed a prototype(原型机) for a device he calls the Presto Emergency Boat Ladder. His invention is a small folding ladder that attaches to the side of a boat to help people who fall into the water. Mr. Mountain plans to mass-produce his boat ladder.
He created his invention at a workshop called TechShop . Mr. Mountain says, "I think it encourages innovation. I think people who probably have had ideas rolling around in the back of their minds for years but have never had the opportunity to actually put them into production or even experiment with them would find this place wonderful. Members of TechShop use high-tech equipment to develop and produce ideas they have for inventions. "Isabella Musachio manages a TechShop in Arlington, Virginia. She says the shop has many different kinds of equipment.
"TechShop is a do-it-yourself maker space. So when you come in we have all these different areas of the shop, and we have a metal shop, wood shop, lasers, 3D printers, electronics. I mean, we have so many different areas and we have all the equipment that is available to anybody above the age of 12. "
Membership costs for TechShop start at just over $ 100 per month. Members are able to use costly machines including 3D modeling tools and laser cutters. Isabella Musachio says TechShop helps its members build their dreams.
"Our motto is 'build your dreams here' because you can really come in with just an idea, and then with the help of TechShop make that leap from an idea to building your project o, your prototype or even your business."
